用于微信小程序的socket库

需要服务器配合，服务器需要返回一样的结构体

interface MessageConstructor{
  type:string,      // 默认返回 "ALL"
  payload?:any,     // 要发送的数据体
  id?:string        // 此id为消息发送者的消息id，如果有，则返回
}

特性

• 简单易容的API
• 使得每次发送数据，都可以得到一个Promise

Usage

yarn add @axetroy/wxapp-socket;

const wxSocket = require('@axetroy/wxapp-socket');

new wxSocket({
    url: 'ws://0.0.0.0:10086'
});

wxSocket.on(function(msg) {
  // ...
});

wxSocket.send('hello world')
.then(function(res) {
  // ...
});

API

new wxSocket(config);

• Arguments
  • config

      interface Config {
        url: string;
        data?: any;
        header?: any;
        method?: string;
        retryTimes?: number,        // 重连次数，默认无限重连
        retryInterval?: number,     // 重连间隔，默认3s，可以设置最低100ms
        success?: () => any;
        fail?: () => any;
        complete?: () => any;
      }

wxSocket.on([type:string], callback): () => any[]

• Arguments
  • type?string，服务器返回的消息类型。当传入type时，指定监听某一类的消息，不传则接收所有消息
  • callback:Function，接收到消息后的回调函数
• Return
  • {Function} 返回一个函数，用于取消监听

wxSocket.send(msg: any, [config]) : Promise

发送消息至服务器，type指定类型，如果不指定，则type默认是message

• Arguments
  • msg?any，发送的消息
  • config:Object，配置

  interface SendMessageConfig {
    noResponse?: boolean,          // 无需等待服务器响应，只要数据发送成功，则resolve
    timeout?: number               // 超时，数据发出之后，xx毫秒没有相应则算超时，reject
  }

• Return
  • {Promise} 返回一个promise
• Example

  wxSocket.send('hello world');
  /*
    实际发送
    {
      "type": "MESSAGE",
      "payload": "hello world",
      "id": "1484540236270908"    // 每一条信息都产生不同的id
    }
  */
  wxSocket.send({type:'LOGIN',payload:{name:"axe",age:100}});
  /*
    实际发送
    {
      "type": "LOGIN",
      "payload": {
        name: "axe",
        age: 100
      },
      "id": "1484540236270908"
    }
  */

wxSocket.socketOpen:boolean

当前socket是否正在链接

wxSocket.messageQueue:array

当前的消息队列，只要在socket未连接，然后又使用wxSocket.send方法的情况下，会把消息放入队列

当socket重新连上之后，会重新发送消息
