Module

soap.createClient(url[, options], callback) - create a new SOAP client from a WSDL url. Also supports a local filesystem path.

• url (string): A HTTP/HTTPS URL, XML or a local filesystem path.
• options (Object):
  • endpoint (string): Override the host specified by the SOAP service in the WSDL file.
  • envelopeKey (string): Set a custom envelope key. (Default: 'soap')
  • preserveWhitespace (boolean): Preserve any leading and trailing whitespace characters in text and cdata.
  • escapeXML (boolean): Escape special XML characters (e.g. &, >, < etc) in SOAP messages. (Default: true)
  • suppressStack (boolean): Suppress the full stack trace for error messages.
  • returnFault (boolean): Return an Invalid XML SOAP fault upon a bad request. (Default: false)
  • forceSoap12Headers (boolean): Enable SOAP 1.2 compliance.
  • httpClient (Object): Override the built-in HttpClient object with your own. Must implement request(rurl, data, callback, exheaders, exoptions).
  • request (Object): Override the default request module (Axios as of v0.40.0).
  • wsdl_headers (Object): Set HTTP headers with values to be sent on WSDL requests.
  • wsdl_options (Object): Set options for the request module on WSDL requests. If using the default request module, see Request Config | Axios Docs.
  • disableCache (boolean): Prevents caching WSDL files and option objects.
  • wsdlCache (IWSDLCache): Custom cache implementation. If not provided, defaults to caching WSDLs indefinitely.
  • overridePromiseSuffix (string): Override the default method name suffix of WSDL operations for Promise-based methods. If any WSDL operation name ends with Async', you must use this option. (**Default:** Async`)
  • normalizeNames (boolean): Replace non-identifier characters ([^a-z$_0-9]) with _ in WSDL operation names. Note: Clients using WSDLs with two operations like soap:method and soap-method will be overwritten. In this case, you must use bracket notation instead (client['soap:method']()).
  • namespaceArrayElements (boolean): Support non-standard array semantics. JSON arrays of the form {list: [{elem: 1}, {elem: 2}]} will be marshalled into XML as <list><elem>1</elem></list> <list><elem>2</elem></list>. If false, it would be marshalled into <list> <elem>1</elem> <elem>2</elem> </list>. (Default: true)
  • stream (boolean): Use streams to parse the XML SOAP responses. (Default: false)
  • returnSaxStream (boolean): Return the SAX stream, transferring responsibility of parsing XML to the end user. Only valid when the stream option is set to true. (Default: false)
  • parseReponseAttachments (boolean): Treat response as multipart/related response with MTOM attachment. Reach attachments on the lastResponseAttachments property of SoapClient. (Default: false)
• callback (Function):
  • err (Error | )
  • result (Any)
• Returns: Client

Example

HTTP/HTTPS:

1  var soap = require('soap');
2  var url = 'http://example.com/wsdl?wsdl';
3  var args = {name: 'value'};
4
5  soap.createClient(url, {}, function(err, client) {
6      client.MyFunction(args, function(err, result) {
7          console.log(result);
8      });
9  });

XML string format:

1  var soap = require('soap');
2  var xml = `
3    <?xml version="1.0" encoding="UTF-8"?>
4    <definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
5       <message name="MyFunctionRequest"/>
6       <message name="MyFunctionResponse"/>

18             <soap:operation soapAction="MyFunction"/>
19             <input><soap:body use="encoded"/></input>
20             <output><soap:body use="encoded"/></output>
21          </operation>
22       </binding>
23    
24       <service name="MyService">
25          <port binding="MyFunctionBinding" name="MyFunctionPort">
26             <soap:address location="http://www.examples.com/MyFunction/" />
27          </port>
28       </service>
29    </definitions>
30  `;
31  var args = {name: 'value'};
32
33  soap.createClient(xml, {}, function(err, client) {
34      client.MyFunction(args, function(err, result) {
35          console.log(result);
36      });
37  });

Note: for versions of node >0.10.X, you may need to specify {connection: 'keep-alive'} in SOAP headers to avoid truncation of longer chunked responses.

soap.createClientAsync(url[, options]) - create a new SOAP client from a WSDL url. Also supports a local filesystem path.

Construct a Promise<Client> with the given WSDL file.

• url (string): A HTTP/HTTPS URL, XML or a local filesystem path.
• options (Object): See soap.createClient(url[, options], callback) for a description.
• Returns: Promise<Client>

Example

1  var soap = require('soap');
2  var url = 'http://example.com/wsdl?wsdl';
3  var args = {name: 'value'};
4
5  // then/catch
6  soap.createClientAsync(url).then((client) => {
7    return client.MyFunctionAsync(args);
8  }).then((result) => {
9    console.log(result);
10  });
11
12  // async/await
13  var client = await soap.createClientAsync(url);
14  var result = await client.MyFunctionAsync(args);
15  console.log(result[0]);

Note: for versions of node >0.10.X, you may need to specify {connection: 'keep-alive'} in SOAP headers to avoid truncation of longer chunked responses.

soap.listen(server, path, services, wsdl, callback) - create a new SOAP server that listens on path and provides services.

soap.listen(server, options) - create a new SOAP server that listens on path and provides services.

• server (Object): A http server or Express framework based server.
• path (string)
• options (Object): An object containing server options and WSDL Options
  • path (string)
  • services (Object)
  • xml (string)
  • uri (string)
  • pfx (string | Buffer): The private key, certificate and CA certs of the server in PFX or PKCS12 format. (Mutually exclusive with the key, cert and ca options.)
  • key (string | Buffer): The private key of the server in PEM format. (Could be an array of keys). (Required)
  • passphrase (string): The passphrase for the private key or pfx.
  • cert (string | Buffer): The certificate key of the server in PEM format. (Could be an array of certs). (Required)
  • ca (string[] | Buffer[]): Trusted certificates in PEM format. If this is omitted several well known "root" CAs will be used, like VeriSign. These are used to authorize connections.
  • crl (string | string[]: PEM encoded CRLs (Certificate Revocation List)
  • ciphers (string): A description of the ciphers to use or exclude, separated by :. The default cipher suite is:
  • enableChunkedEncoding (boolean): Controls chunked transfer encoding in response. Some clients (such as Windows 10's MDM enrollment SOAP client) are sensitive to transfer-encoding mode and can't accept chunked response. This option lets users disable chunked transfer encoding for such clients. (Default: true)
• services (Object)
• wsdl (string): An XML string that defines the service.
• callback (Function): A function to run after the server has been initialized.
• Returns: Server

9    // WSDL options.
10    attributesKey: 'theAttrs',
11    valueKey: 'theVal',
12    xmlKey: 'theXml'
13});

Server Logging

If the log method is defined, it will be called with:

• type: 'received', 'replied', 'info' or 'error'.
• data: The data to be logged which will be an XML for 'received' and 'replied' or a message for the other types.
• req: The original request object

1  server = soap.listen(...)
2  server.log = function(type, data, req) {
3    // type is 'received', 'replied', 'info' or 'error'
4  };

Server Events

Server instances emit the following events:

• request - Emitted for every received messages. The signature of the callback is function(request, methodName).
• response - Emitted before sending SOAP response. The signature of the callback is function(response, methodName).
• headers - Emitted when the SOAP Headers are not empty. The signature of the callback is function(headers, methodName).

The sequence order of the calls is request, headers and then the dedicated service method.

Server Response on one-way calls

The so called one-way (or asynchronous) calls occur when an operation is called with no output defined in WSDL. The server sends a response (defaults to status code 200 with no body) to the client disregarding the result of the operation.

You can configure the response to match the appropriate client expectation to the SOAP standard implementation. Pass in oneWay object in server options. Use the following keys: emptyBody: if true, returns an empty body, otherwise no content at all (default is false) responseCode: default statusCode is 200, override it with this options (for example 202 for SAP standard compliant response)

SOAP Fault

A service method can reply with a SOAP Fault to a client by throwing an object with a Fault property.

1  throw {
2    Fault: {
3      Code: {
4        Value: 'soap:Sender',
5        Subcode: { value: 'rpc:BadArguments' }
6      },
7      Reason: { Text: 'Processing Error' }
8    }
9  };

To change the HTTP statusCode of the response include it on the fault. The statusCode property will not be put on the xml message.

1  throw {
2    Fault: {
3      Code: {
4        Value: 'soap:Sender',
5        Subcode: { value: 'rpc:BadArguments' }
6      },
7      Reason: { Text: 'Processing Error' },
8      statusCode: 500
9    }
10  };

Server security example using PasswordDigest

If server.authenticate is not defined then no authentication will take place.

Asynchronous authentication:

1  server = soap.listen(...)
2  server.authenticate = function(security, callback) {
3    var created, nonce, password, user, token;
4    token = security.UsernameToken, user = token.Username,
5            password = token.Password, nonce = token.Nonce, created = token.Created;
6
7    myDatabase.getUser(user, function (err, dbUser) {
8      if (err || !dbUser) {
9        callback(false);
10        return;
11      }
12
13      callback(password === soap.passwordDigest(nonce, created, dbUser.password));
14    });
15  };

Synchronous authentication:

1  server = soap.listen(...)
2  server.authenticate = function(security) {
3    var created, nonce, password, user, token;
4    token = security.UsernameToken, user = token.Username,
5            password = token.Password, nonce = token.Nonce, created = token.Created;
6    return user === 'user' && password === soap.passwordDigest(nonce, created, 'password');
7  };

Server connection authorization

The server.authorizeConnection method is called prior to the soap service method. If the method is defined and returns false then the incoming connection is terminated.

1  server = soap.listen(...)
2  server.authorizeConnection = function(req) {
3    return true; // or false
4  };

SOAP Headers

Received SOAP Headers

A service method can look at the SOAP headers by providing a 3rd arguments.

1  {
2      HeadersAwareFunction: function(args, cb, headers) {
3          return {
4              name: headers.Token
5          };
6      }
7  }

It is also possible to subscribe to the 'headers' event. The event is triggered before the service method is called, and only when the SOAP Headers are not empty.

1  server = soap.listen(...)
2  server.on('headers', function(headers, methodName) {
3    // It is possible to change the value of the headers
4    // before they are handed to the service method.
5    // It is also possible to throw a SOAP Fault
6  });

First parameter is the Headers object; second parameter is the name of the SOAP method that will called (in case you need to handle the headers differently based on the method).

Outgoing SOAP Headers

Both client & server can define SOAP headers that will be added to what they send. They provide the following methods to manage the headers.

addSoapHeader(soapHeader[, name, namespace, xmlns]) - add soapHeader to soap:Header node

Parameters

• soapHeader Object({rootName: {name: 'value'}}), strict xml-string, or function (server only)

For servers only, soapHeader can be a function, which allows headers to be dynamically generated from information in the request. This function will be called with the following arguments for each received request:

• methodName The name of the request method
• args The arguments of the request
• headers The headers in the request
• req The original request object

The return value of the function must be an Object({rootName: {name: 'value'}}) or strict xml-string, which will be inserted as an outgoing header of the response to that request.

For example:

1  server = soap.listen(...);
2  server.addSoapHeader(function(methodName, args, headers, req) {
3    console.log('Adding headers for method', methodName);
4    return {
5      MyHeader1: args.SomeValueFromArgs,
6      MyHeader2: headers.SomeRequestHeader
7    };
8    // or you can return "<MyHeader1>SomeValue</MyHeader1>"
9  });

Returns

The index where the header is inserted.

Optional parameters when first arg is object :

• name Unknown parameter (it could just a empty string)
• namespace prefix of xml namespace
• xmlns URI

changeSoapHeader(index, soapHeader[, name, namespace, xmlns]) - change an already existing soapHeader

Parameters

• index index of the header to replace with provided new value
• soapHeader Object({rootName: {name: 'value'}}), strict xml-string or function (server only)

See addSoapHeader for how to pass a function into soapHeader.

getSoapHeaders() - return all defined headers

clearSoapHeaders() - remove all defined headers

Client

An instance of Client is passed to the soap.createClient callback. It is used to execute methods on the soap service.

Client.describe() - description of services, ports and methods as a JavaScript object

1  client.describe() // returns
2    {
3      MyService: {
4        MyPort: {
5          MyFunction: {
6            input: {
7              name: 'string'
8            }
9          }
10        }
11      }
12    }

Client.setSecurity(security) - use the specified security protocol

See Security for example usage.

Client.method(args, callback, options) - call method on the SOAP service.

• args (Object): Arguments that generate an XML document inside of the SOAP Body section.
• callback (Function)
• options (Object): Set options for the request module on WSDL requests. If using the default request module, see Request Config | Axios Docs. Additional options supported by node-soap are documented below:
  • forever (boolean): Enables keep-alive connections and pools them
  • attachments (Array): array of attachment objects. This converts the request into MTOM: headers['Content-Type']='multipart/related; type="application/xop+xml"; start= ... '

  [{
        mimetype: content mimetype,
        contentId: part id,
        name: file name,
        body: binary data
   },
    ...
  ]
  

  • forceMTOM (boolean): Send the request as MTOM even if you don't have attachments.
  • forceGzip (boolean): Force transfer-encoding in gzip. (Default: false)

Example

1  client.MyFunction({name: 'value'}, function(err, result, rawResponse, soapHeader, rawRequest) {
2      // result is a javascript object
3      // rawResponse is the raw xml response string
4      // soapHeader is the response soap header as a javascript object
5      // rawRequest is the raw xml request string
6  })

Client.methodAsync(args, options) - call method on the SOAP service.

• args (Object): Arguments that generate an XML document inside of the SOAP Body section.
• options (Object): See Client.method(args, callback, options) - call method on the SOAP service. for a description.

Example

1  client.MyFunctionAsync({name: 'value'}).then((result) => {
2    // result is a javascript array containing result, rawResponse, soapheader, and rawRequest
3    // result is a javascript object
4    // rawResponse is the raw xml response string
5    // soapHeader is the response soap header as a javascript object
6    // rawRequest is the raw xml request string
7  })

Example with JSON for the args

The example above uses {name: 'value'} as the args. This may generate a SOAP messages such as:

1<?xml version="1.0" encoding="utf-8"?>
2<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
3   <soapenv:Body>
4      <Request xmlns="http://www.example.com/v1">
5          <name>value</name>
6      </Request>
7   </soapenv:Body>
8</soapenv:Envelope>

Note that the "Request" element in the output above comes from the WSDL. If an element in args contains no namespace prefix, the default namespace is assumed. Otherwise, you must add the namespace prefixes to the element names as necessary (e.g., ns1:name).

Currently, when supplying JSON args, elements may not contain both child elements and a text value, even though that is allowed in the XML specification.

Example with XML String for the args

You may pass in a fully-formed XML string instead the individual elements in JSON args and attributes that make up the XML. The XML string should not contain an XML declaration (e.g., <?xml version="1.0" encoding="UTF-8"?>) or a document type declaration (e.g., <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd">).

 var args = { _xml: "<ns1:MyRootElement xmlns:ns1="http://www.example.com/v1/ns1">
                        <ChildElement>elementvalue</ChildElement>
                     </ns1:MyRootElement>"
            };

You must specify all of the namespaces and namespace prefixes yourself. The element(s) from the WSDL are not utilized as they were in the "Example with JSON as the args" example above, which automatically populated the "Request" element.

Client.service.port.method(args, callback[, options[, extraHeaders]]) - call a method using a specific service and port

• args (Object): Arguments that generate an XML document inside of the SOAP Body section.
• callback (Function)
• options (Object): See Client.method(args, callback, options) - call method on the SOAP service. for a description.
• extraHeaders (Object): Sets HTTP headers for the WSDL request.

Example

1  client.MyService.MyPort.MyFunction({name: 'value'}, function(err, result) {
2      // result is a javascript object
3  })

Options (optional)

• Accepts any option that the request module accepts, see here.
• For example, you could set a timeout of 5 seconds on the request like this:

1  client.MyService.MyPort.MyFunction({name: 'value'}, function(err, result) {
2      // result is a javascript object
3  }, {timeout: 5000})

• You can measure the elapsed time on the request by passing the time option:

1  client.MyService.MyPort.MyFunction({name: 'value'}, function(err, result) {
2      // client.lastElapsedTime - the elapsed time of the last request in milliseconds
3  }, {time: true})

• Also, you could pass your soap request through a debugging proxy such as Fiddler or Betwixt.

1  client.MyService.MyPort.MyFunction({name: 'value'}, function(err, result) {
2      // client.lastElapsedTime - the elapsed time of the last request in milliseconds
3  }, {
4      proxy: {
5          protocol: 'https',
6          host: '127.0.0.1',
7          port: 9000,
8          auth: {
9              username: 'mikeymike',
10              password: 'rapunz3l'
11          }
12      }
13  })

• You can modify xml (string) before call:

1  client.MyService.MyPort.MyFunction({name: 'value'}, function(err, result) {
2      // client.lastElapsedTime - the elapsed time of the last request in milliseconds
3  }, {postProcess: function(_xml) {
4    return _xml.replace('text', 'newtext');
5  }})

Extra Headers (optional)

Object properties define extra HTTP headers to be sent on the request.

• Add custom User-Agent:

1client.addHttpHeader('User-Agent', `CustomUserAgent`);

Alternative method call using callback-last pattern

To align method call signature with node' standard callback-last patter and event allow promisification of method calls, the following method signatures are also supported:

1client.MyService.MyPort.MyFunction({name: 'value'}, options, function (err, result) {
2  // result is a javascript object
3})
4
5client.MyService.MyPort.MyFunction({name: 'value'}, options, extraHeaders, function (err, result) {
6  // result is a javascript object
7})

Overriding the namespace prefix

node-soap is still working out some kinks regarding namespaces. If you find that an element is given the wrong namespace prefix in the request body, you can add the prefix to it's name in the containing object. I.E.:

1  client.MyService.MyPort.MyFunction({'ns1:name': 'value'}, function(err, result) {
2      // request body sent with `<ns1:name`, regardless of what the namespace should have been.
3  }, {timeout: 5000})

• Remove namespace prefix of param

1  client.MyService.MyPort.MyFunction({':name': 'value'}, function(err, result) {
2      // request body sent with `<name`, regardless of what the namespace should have been.
3  }, {timeout: 5000})

Client.lastRequest - the property that contains last full soap request for client logging

Client.setEndpoint(url) - overwrite the SOAP service endpoint address

Client Events

Client instances emit the following events:

request

Emitted before a request is sent. The event handler has the signature (xml, eid).

• xml - The entire Soap request (Envelope) including headers.
• eid - The exchange id.

message

Emitted before a request is sent, but only the body is passed to the event handler. Useful if you don't want to log /store Soap headers. The event handler has the signature (message, eid).

• message - Soap body contents.
• eid - The exchange id.

soapError

Emitted when an erroneous response is received. Useful if you want to globally log errors. The event handler has the signature (error, eid).

• error - An error object which also contains the resoponse.
• eid - The exchange id.

response

Emitted after a response is received. This is emitted for all responses (both success and errors). The event handler has the signature (body, response, eid)

• body - The SOAP response body.
• response - The entire IncomingMessage response object.
• eid - The exchange id.

An 'exchange' is a request/response couple. Event handlers receive the exchange id in all events. The exchange id is the same for the requests events and the responses events, this way you can use it to retrieve the matching request when an response event is received.

By default exchange ids are generated by using node-uuid but you can use options in client calls to pass your own exchange id.

Example :

1  client.MyService.MyPort.MyFunction(args , function(err, result) {
2
3  }, {exchangeId: myExchangeId})

WSDL

A WSDL instance can also be instantiated directly when you want to (un)marshal messages without doing SOAP calls. This can be used when a WSDL does not contain bindings for services (e.g. some Windows Communication Foundation SOAP web services).

WSDL.constructor(wsdl, baseURL, options):

Construct a WSDL instance from either the WSDL content or the URL to the WSDL.

Parameters

• wsdl: A string wSDL or an URL to the WSDL
• baseURL: base URL for the SOAP API
• options: options (see source for details), use {} as default.

wsdl.xmlToObject(xml):

Unmarshal XML to object.

Parameters:

• xml: SOAP response (XML) to unmarshal

Returns:

Object containing the object types from the xml as keys.

wsdl.objectToXML(object, typeName, namespacePrefix, namespaceURI, ...):

Marshal an object to XML

Parameters:

• object: Object to marshal
• typeName: type (as per the wsdl) of the object
• namespacePrefix: namespace prefix
• namespaceURI: URI of the namespace

Returns:

XML representation of object.

Example:

1// Abstracted from a real use case
2import { AxiosInstance } from 'axios';
3import { WSDL } from 'soap';
4import { IProspectType } from './types';
5
6// A WSDL in a string.
7const WSDL_CONTENT = "...";
8
9const httpClient: AxiosInstance = /* ... instantiate ... */;
10const url = 'http://example.org/SoapService.svc';
11
12const wsdl = new WSDL(WSDL_CONTENT, baseURL, {});
13
14async function sampleGetCall(): IProspectType | undefined {
15    const res = await httpClient.get(`${baseURL}/GetProspect`);
16
17    const object = wsdl.xmlToObject(res.data);
18
19    if (!object.ProspectType) {
20      // Response did not contain the expected type
21      return undefined;
22    }
23    // Optionally, unwrap and set defaults for some fields
24    // Ensure that the object meets the expected prototype
25    // Finally cast and return the result.
26    return object.ProspectType as IProspectType;
27}
28
29async function samplePostCall(prospect: IProspectType) {
30  // objectToXML(object, typeName, namespacePrefix, namespaceURI, ...)
31  const objectBody = wsdl.objectToXML(obj, 'ProspectType', '', '');
32  const data = `<?xml version="1.0" ?>${body}`;
33
34  const res = await httpClient.post(`${baseURL}/ProcessProspect`, data);
35  // Optionally, deserialize request and return response status.
36}

Security

node-soap has several default security protocols. You can easily add your own as well. The interface is quite simple. Each protocol defines these optional methods:

• addOptions(options) - a method that accepts an options arg that is eventually passed directly to request.
• addHeaders(headers) - a method that accepts an argument with HTTP headers, to add new ones.
• toXML() - a method that returns a string of XML to be appended to the SOAP headers. Not executed if postProcess is also defined.
• postProcess(xml, envelopeKey) - a method that receives the the assembled request XML plus envelope key, and returns a processed string of XML. Executed before options.postProcess.

BasicAuthSecurity

1  client.setSecurity(new soap.BasicAuthSecurity('username', 'password'));

BearerSecurity

1  client.setSecurity(new soap.BearerSecurity('token'));

ClientSSLSecurity

Note: If you run into issues using this protocol, consider passing these options as default request options to the constructor:

• rejectUnauthorized: false
• strictSSL: false
• secureOptions: constants.SSL_OP_NO_TLSv1_2 (this is likely needed for node >= 10.0)

If you want to reuse tls sessions, you can use the option forever: true.

1client.setSecurity(new soap.ClientSSLSecurity(
2                '/path/to/key',
3                'path/to/cert',
4                '/path/to/ca-cert',  /*or an array of buffer: [fs.readFileSync('/path/to/ca-cert/1', 'utf8'),
5                'fs.readFileSync('/path/to/ca-cert/2', 'utf8')], */
6                {   /*default request options like */
7                    // strictSSL: true,
8                    // rejectUnauthorized: false,
9                    // hostname: 'some-hostname'
10                    // secureOptions: constants.SSL_OP_NO_TLSv1_2,
11                    // forever: true,
12                },
13      ));

ClientSSLSecurityPFX

Note: If you run into issues using this protocol, consider passing these options as default request options to the constructor:

• rejectUnauthorized: false
• strictSSL: false
• secureOptions: constants.SSL_OP_NO_TLSv1_2 (this is likely needed for node >= 10.0)

If you want to reuse tls sessions, you can use the option forever: true.

1client.setSecurity(new soap.ClientSSLSecurityPFX(
2                '/path/to/pfx/cert', // or a buffer: [fs.readFileSync('/path/to/pfx/cert', 'utf8'),
3                'path/to/optional/passphrase',
4                {   /*default request options like */
5                    // strictSSL: true,
6                    // rejectUnauthorized: false,
7                    // hostname: 'some-hostname'
8                    // secureOptions: constants.SSL_OP_NO_TLSv1_2,
9                    // forever: true,
10                },
11      ));

WSSecurity

WSSecurity implements WS-Security. UsernameToken and PasswordText/PasswordDigest is supported.

1  var options = {
2    hasNonce: true,
3    actor: 'actor'
4  };
5  var wsSecurity = new soap.WSSecurity('username', 'password', options)
6  client.setSecurity(wsSecurity);

the options object is optional and can contain the following properties:

• passwordType: 'PasswordDigest' or 'PasswordText' (default: 'PasswordText')
• hasTimeStamp: adds Timestamp element (default: true)
• hasTokenCreated: adds Created element (default: true)
• hasNonce: adds Nonce element (default: false)
• mustUnderstand: adds mustUnderstand=1 attribute to security tag (default: false)

17     }
18  }
19  var wsSecurity = new soap.WSSecurityCert(privateKey, publicKey, password, options);
20  client.setSecurity(wsSecurity);

The options object is optional and can contain the following properties:

• hasTimeStamp: Includes Timestamp tags (default: true)
• signatureTransformations: sets the Reference Transforms Algorithm (default ['http://www.w3.org/2000/09/xmldsig#enveloped-signature', 'http://www.w3.org/2001/10/xml-exc-c14n#']). Type is a string array
• signatureAlgorithm: set to http://www.w3.org/2001/04/xmldsig-more#rsa-sha256 to use sha256

WSSecurityCertWithToken

WS-Security X509 Certificate support. Just like WSSecurityCert, except that it accepts the input properties as a single object, with two properties added username and password. Which if added, will add a UsernameToken Element to the xml security element.

1<wsse:UsernameToken>
2  <wsse:Username>someusername</wsse:Username>
3  <wsse:Password>someusername's password</wsse:Password>
4</wsse:UsernameToken>

NTLMSecurity

Parameter invocation:

1  client.setSecurity(new soap.NTLMSecurity('username', 'password', 'domain', 'workstation'));

This can also be set up with a JSON object, substituting values as appropriate, for example:

1  var loginData = {username: 'username', password: 'password', domain: 'domain', workstation: 'workstation'};
2  client.setSecurity(new soap.NTLMSecurity(loginData));

Handling XML Attributes, Value and XML (wsdlOptions).

Sometimes it is necessary to override the default behaviour of node-soap in order to deal with the special requirements of your code base or a third library you use. Therefore you can use the wsdlOptions Object, which is passed in the #createClient() method and could have any (or all) of the following contents:

1var wsdlOptions = {
2  attributesKey: 'theAttrs',
3  valueKey: 'theVal',
4  xmlKey: 'theXml'
5}

If nothing (or an empty Object {}) is passed to the #createClient() method, the node-soap defaults (attributesKey: 'attributes', valueKey: '$value' and xmlKey: '$xml') are used.

Overriding the value key

By default, node-soap uses $value as the key for any parsed XML value which may interfere with your other code as it could be some reserved word, or the $ in general cannot be used for a key to start with.

You can define your own valueKey by passing it in the wsdl_options to the createClient call:

1var wsdlOptions = {
2  valueKey: 'theVal'
3};
4
5soap.createClient(__dirname + '/wsdl/default_namespace.wsdl', wsdlOptions, function (err, client) {
6  // your code
7});

Overriding the xml key

By default, node-soap uses $xml as the key to pass through an XML string as is; without parsing or namespacing it. It overrides all the other content that the node might have otherwise had.

For example :

1{
2  dom: {
3    nodeone: {
4      $xml: '<parentnode type="type"><childnode></childnode></parentnode>',
5      siblingnode: 'Cant see me.'
6    },
7    nodetwo: {
8      parentnode: {
9        attributes: {
10          type: 'type'
11        },
12        childnode: ''
13      }
14    }
15  }
16};

could become

1<tns:dom>
2  <tns:nodeone>
3    <parentnode type="type">
4      <childnode></childnode>
5    </parentnode>
6  </tns:nodeone>
7  <tns:nodetwo>
8    <tns:parentnode type="type">
9      <tns:childnode></tns:childnode>
10    </tns:parent>
11  </tns:nodetwo>
12</tns:dom>

You can define your own xmlKey by passing it in the wsdl_options object to the createClient call:

1var wsdlOptions = {
2  xmlKey: 'theXml'
3};
4
5soap.createClient(__dirname + '/wsdl/default_namespace.wsdl', wsdlOptions, function (err, client) {
6  // your code
7});

Overriding the attributes key

By default, node-soap uses attributes as the key to define a nodes attributes.

1{
2  parentnode: {
3    childnode: {
4      attributes: {
5        name: 'childsname'
6      },
7      $value: 'Value'
8    }
9  }
10}

could become

1<parentnode>
2  <childnode name="childsname">Value</childnode>
3</parentnode>

However, attributes may be a reserved key for some systems that actually want a node called attributes

1<attributes>
2</attributes>

You can define your own attributesKey by passing it in the wsdl_options object to the createClient call:

1var wsdlOptions = {
2  attributesKey: '$attributes'
3};
4
5soap.createClient(__dirname + '/wsdl/default_namespace.wsdl', wsdlOptions, function (err, client) {
6  client.method({
7    parentnode: {
8      childnode: {
9        $attributes: {
10          name: 'childsname'
11        },
12        $value: 'Value'
13      }
14    }
15  });
16});

Overriding imports relative paths

By default, WSDL and schema files import other schemas and types using relative paths.

However in some systems (i.e. NetSuite) when the wsdl is downloaded for offline caching, all files are flattened under a single directory and all the imports fail. Passing this option allows node-soap to correctly load all files.

1var options ={
2    wsdl_options = { fixedPath: true }
3};
4soap.createClient(__dirname+'/wsdl/fixedPath/netsuite.wsdl', options, function(err, client) {
5    // your code
6});

Overriding import locations

You can override the URIs or paths of imports in the WSDL by specifying a overrideImportLocation function in the WSDL options.

1const options ={
2    wsdl_options = {
3        overrideImportLocation: (location) => {
4          return 'https://127.0.0.1/imported-service.wsdl';
5        }
6    }
7};
8soap.createClient('https://127.0.0.1/service.wsdl', options, function(err, client) {
9    // your code
10});

Specifying the exact namespace definition of the root element

In rare cases, you may want to precisely control the namespace definition that is included in the root element.

You can specify the namespace definitions by setting the overrideRootElement key in the wsdlOptions like so:

1var wsdlOptions = {
2  overrideRootElement: {
3    namespace: 'xmlns:tns',
4    xmlnsAttributes: [{
5      name: 'xmlns:ns2',
6      value: "http://tempuri.org/"
7    }, {
8      name: 'xmlns:ns3',
9      value: "http://sillypets.com/xsd"
10    }]
11  }
12};

To see it in practice, have a look at the sample files in: test/request-response-samples/addPets__force_namespaces

Custom Deserializer

Sometimes it's useful to handle deserialization in your code instead of letting node-soap do it. For example if the soap response contains dates that are not in a format recognized by javascript, you might want to use your own function to handle them.

To do so, you can pass a customDeserializer object in options. The properties of this object are the types that your deserializer handles itself.

Example :

1
2   var wsdlOptions = {
3     customDeserializer: {
4
5       // this function will be used to any date found in soap responses
6       date: function (text, context) {
7         /* text is the value of the xml element.
8           context contains the name of the xml element and other infos :
9             {
10                 name: 'lastUpdatedDate',
11                 object: {},
12                 schema: 'xsd:date',
13                 id: undefined,
14                 nil: false
15             }
16
17          */
18         return text;
19       }
20     }
21   };
22
23   soap.createClient(__dirname + '/wsdl/default_namespace.wsdl', wsdlOptions, function (err, client) {
24     ...
25   });
26

Changing the tag formats to use self-closing (empty element) tags

The XML specification specifies that there is no semantic difference between <Tag></Tag> and <Tag />, and node-soap defaults to using the <Tag></Tag> format. But if your web service is particular, or if there is a stylistic preference, the useEmptyTag option causes tags with no contents to use the <Tag /> format instead.

1var wsdlOptions = {
2  useEmptyTag: true
3};

For example: { MyTag: { attributes: { MyAttr: 'value' } } } is:

• Without useEmptyTag: <MyTag MyAttr="value"></MyTag>
• With useEmptyTag set to true: <MyTag MyAttr="value" />

Handling "ignored" namespaces

If an Element in a schema definition depends on an Element which is present in the same namespace, normally the tns: namespace prefix is used to identify this Element. This is not much of a problem as long as you have just one schema defined (inline or in a separate file). If there are more schema files, the tns: in the generated soap file resolved mostly to the parent wsdl file, which was obviously wrong.

node-soap now handles namespace prefixes which shouldn't be resolved (because it's not necessary) as so called ignoredNamespaces which default to an Array of 3 Strings (['tns', 'targetNamespace', 'typedNamespace']).

If this is not sufficient for your purpose you can easily add more namespace prefixes to this Array, or override it in its entirety by passing an ignoredNamespaces object within the options you pass in soap.createClient() method.

A simple ignoredNamespaces object, which only adds certain namespaces could look like this:

var options = {
  ignoredNamespaces: {
    namespaces: ['namespaceToIgnore', 'someOtherNamespace']
  }
}

This would extend the ignoredNamespaces of the WSDL processor to ['tns', 'targetNamespace', 'typedNamespace', 'namespaceToIgnore', 'someOtherNamespace'].

If you want to override the default ignored namespaces you would simply pass the following ignoredNamespaces object within the options:

var options = {
    ignoredNamespaces: {
      namespaces: ['namespaceToIgnore', 'someOtherNamespace'],
      override: true
    }
  }

This would override the default ignoredNamespaces of the WSDL processor to ['namespaceToIgnore', 'someOtherNamespace']. (This shouldn't be necessary, anyways).

Handling "ignoreBaseNameSpaces" attribute

If an Element in a schema definition depends has a basenamespace defined but the request does not need that value, for example you have a "sentJob" with basenamespace "v20" but the request need only: set in the tree structure, you need to set the ignoreBaseNameSpaces to true. This is set because in a lot of workaround the wsdl structure is not correctly set or the webservice bring errors.

By default the attribute is set to true. An example to use:

A simple ignoredNamespaces object, which only adds certain namespaces could look like this:

var options = {
ignoredNamespaces: true
}

soap-stub

Unit testing services that use soap clients can be very cumbersome. In order to get around this you can use soap-stub in conjunction with sinon to stub soap with your clients.

Example

1// test-initialization-script.js
2var sinon = require('sinon');
3var soapStub = require('soap/soap-stub');
4
5var urlMyApplicationWillUseWithCreateClient = 'http://path-to-my-wsdl';
6var clientStub = {
7  SomeOperation: sinon.stub()
8};
9
10clientStub.SomeOperation.respondWithError = soapStub.createErroringStub({..error json...});
11clientStub.SomeOperation.respondWithSuccess = soapStub.createRespondingStub({..success json...});
12
13soapStub.registerClient('my client alias', urlMyApplicationWillUseWithCreateClient, clientStub);
14
15// test.js
16var soapStub = require('soap/soap-stub');
17
18describe('myService', function() {
19  var clientStub;
20  var myService;
21
22  beforeEach(function() {
23    clientStub = soapStub.getStub('my client alias');
24    soapStub.reset();
25    myService.init(clientStub);
26  });
27
28  describe('failures', function() {
29    beforeEach(function() {
30      clientStub.SomeOperation.respondWithError();
31    });
32
33    it('should handle error responses', function() {
34      myService.somethingThatCallsSomeOperation(function(err, response) {
35        // handle the error response.
36      });
37    });
38  });
39});
