vue websocket，复制即用

<template>
  <div class="test">
    <p v-for="item in msglist">{{item.data}}</p>
  </div>
</template>

<script>
  export default {
    name : 'test',
    data() {
      return {
        websock: null,
        msglist: []
      }
    },
    created() {
      this.initWebSocket();
    },
    destroyed() {
      this.websock.close() //离开路由之后断开websocket连接
    },
    methods: {
      initWebSocket(){ //初始化weosocket
        const wsuri = "ws://127.0.0.1:8000/ws/chat/www/";
        this.websock = new WebSocket(wsuri);
        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 = {"test":"12345"};
        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);
        console.log(e)
        this.msglist.push(e)

      },
      websocketsend(Data){//数据发送
        this.websock.send(Data);
      },
      websocketclose(e){  //关闭
        console.log('断开连接',e);
      },
    },
  }
</script>

　　

后端使用django channels，注意版本，不同版本使用方式稍有差异

谷歌浏览器测试连接状态：

ws = new WebSocket('wss://a.b.c/ws/monitoring/syncConfig/');
或者
ws = new WebSocket('wss://a.b.c/ws/monitoring/syncConfig/');
ws.onopen=function(data){console.log(data)};
ws.onmessage=function(data){console.log(data)};
ws.onclose=function(data){console.log(data)};
ws.onerror=function(data){console.log(data)};
ws.send('msg');
