多对多聊天

单对单聊天

3.websocket后端代码

1. 安装weosocket
npm install websocket --save
2.在js文件下写一下代码：
const ws = require('nodejs-websocket');
 //arr  记录有多少人进入聊天
const arr = []
const server = ws.createServer(connect => {
//userId 可以从前端传进来
    const useId = new Date().getTime()
    connect.userName = `用户${useId}`;
    arr.push({
        userName:connect.userName,
        value: '加入聊天室',
        connect,
    })
    broadcast(arr)
    
    connect.on('text', data => {
        const params = {
            connect,
            userName:connect.userName,
            value: data,
        }
        arr.push(params)
        broadcast(arr)
    });
 
    //连接关闭触发close事件
    connect.on('close',()=>{
        arr.push({
            userName:connect.userName,
            value: '离开了聊天室',
        })
    });
 
    //注册error事件,用户端口后就会触发该异常
    connect.on('error',()=>{
        console.log('用户连接异常');
    });
});
 
const broadcast = (arr) => {
    const params = arr.map(({userName,value})=>({
        userName,
        value
    }))
    server.connections.forEach(item => {
        item.send(JSON.stringify(params));
    });
}
 
server.listen(5000);

4. 前端代码

<template>
  <div class="test">

  </div>
</template>

<script>
  export default {
    name : 'test',
    data() {
      return {
        websock: null,
        url:'ws://127.0.0.1:8080'
      }
    },
    mounted() {
      this.initWebSocket();
    },
    destroyed() {
      this.websock.close() //离开路由之后断开websocket连接
    },
    methods: {
      initWebSocket(){ //初始化weosocket
        this.websock = new WebSocket(this.url);
        this.websock.onmessage = this.websocketonmessage;
        this.websock.onopen = this.websocketonopen;
        this.websock.onerror = this.websocketonerror;
        this.websock.onclose = this.websocketclose;
      },
      websocketonopen(){ //连接建立之后执行send方法发送数据
        let actions = {"text":"发送信息"};
        this.websocketsend(JSON.stringify(actions));
      },
      websocketonerror(){//连接建立失败重连
        this.initWebSocket();
      },
      websocketonmessage(e){ //数据接收
        const redata = JSON.parse(e.data);
      },
      websocketsend(Data){//数据发送
        this.websock.send(Data);
      },
      websocketclose(e){  //关闭
        console.log('断开连接',e);
      },
    },
  }
</script>
