dubbo
node.js dubbo/dubbox client with zookeeper support via dubbo default hessian protocol.
想到这个项目基本上只给国人用，就破例稍微接地气一点，下面都写中文文档
- TCP 长连接及长连接池
- 动态的服务注册
- 内部使用队列处理 Service 注册的握手过程，调用者无需关心
Install
1$ npm install dubbo --save
Usage
1import Dubbo from 'dubbo' 2 3const dubbo = new Dubbo({ 4 application: 'my-application-name', 5 6 // Dubbo 父节点名 7 root: 'dubbo-test', 8 9 // Dubbo 的版本 10 version: '2.8.4', 11 zookeeper: { 12 host : '10.0.0.100:2181', 13 14 // node-zookeeper-client 的 createClient 方法的 options， 15 sessionTimeout: 30000, 16 spinDelay : 1000, 17 retries : 5 18 }, 19 20 // 需要注册的服务名，还可以使用 `dubbo.register` 方法来动态注册一个服务 21 services: { 22 member: { 23 interface: 'me.kael.service.memberService', 24 timeout: 6000, 25 group, 26 version 27 } 28 }, 29 30 // 1. Object 31 // 对于每一个 service，长连接池的大小 32 // 这些参数会被直接传递给 generic-pool 33 // 2. false 34 // 若不希望使用连接池，则传递 false 35 pool: { 36 max: 200, 37 min: 10, 38 maxWaitingClients: 500 39 } 40}) 41 42 43// 如果一个服务没有注册就被调用，那么会收到一个 Promise.reject 44dubbo.service('member') 45 46// `'login'` 为方法名 47// invoke 方法可以接多个参数 48.invoke('login', { 49 $class: 'me.kael.member.dto.loginDTO', 50 $: { 51 mobile: { 52 $class: 'java.lang.String', 53 $: '18800008888' 54 }, 55 password: { 56 $class: 'java.lang.String', 57 $: 'my-password' 58 } 59 } 60}) 61.then(isSuccess => { 62 console.log('is successful', isSuccess) 63}) 64 65 66// 动态注册一个服务 67dubbo.register('order', { 68 interface: 'me.kael.service.orderService' 69}) 70.service('order') 71.invoke('create', ...) 72.then(...)
new Dubbo(options)
创建一个 Dubbo 实例
options Object
- application
String当前应用的名称 - root
Stringdubbo 的父节点名 - version
String连接的 dubbo 服务使用的 dubbo 版本 - zookeeper
Object- host
Stringzookeeper 的地址，格式为<ip>[:<port>]，若端口没有定义，则默认端口为2181 - 其他
node-zookeeper-client的参数，会直接传递
- host
- services
Object.<name:ServiceOptions>需要预先注册的 services - pool
Object|false连接池的 options，它会直接作为参数传递给generic-pool
ServiceOptions Object
- interface
- timeout
- group
- version
dubbo.register(name, serviceOptions)
注册一个 dubbo service，一个被注册过的 service，可以立即调用它的 service.invoke() 方法，dubbo 与 service 进行 providers 和 consumers 的握手的过程，会被 service 内部的队列处理好。
- name
String - serviceOptions
ServiceOptions
Returns this
dubbo.service(name)
获取一个 service，即使一个名为 name 的 service，没有被注册过，该方法也会返回一个 Service 实例。
但是若一个 service 没有被注册过，那么在调动 service.invoke() 方法的时候，会得到一个 Promise.reject()
Returns Service
1// 若 `member` service 没有注册，仍然能够获取一个 member 实例 2const member = dubbo.service('member') 3 4member.invoke('login', arg).catch(err => { 5 // 但是当调用 invoke 的时候，会得到一个 `SERVICE_NOT_REGISTERED` 的错误 6 console.log(err.code === 'SERVICE_NOT_REGISTERED') 7 // true 8}) 9 10// 然后，我们若注册了 member 这个 service 11dubbo.register('member', { 12 interface: '...', 13 ... 14}) 15 16// 就可以使用这个 service 了 17member.invoke('login', arg) 18.then(isSuccess => { 19 console.log('is successfull:', isSuccess) 20})
service.invoke(methodName, ...args)
请求一个 service 方法。
- methodName
Stringservice 中的方法名，若该方法名不存在，则会得到一个Promise.reject - args
any方法的参数，可传递多个，这里的方法，需要是 java 风格的对象。可以手动拼，或者使用js-to-javamodule.
1service.invoke('createProduct', product1, product2)
Returns Promise
