<script>
    export default {
        data() {
            return {
                websock: null,
            }
        },
    created(){ //页面刚进入时开启长连接
           this.initWebSocket()
       },
    destroyed: function() {//页面销毁时关闭长连接
      this.websocketclose();
    },
    methods: { 
      initWebSocket(){ //初始化weosocket 
       
        const wsuri = "/websocket/threadsocket";//ws地址
        this.websock = new WebSocket(wsuri); 
        this.websocket.onopen = this.websocketonopen;

        this.websocket.onerror = this.websocketonerror;

        this.websock.onmessage = this.websocketonmessage;
        this.websock.onclose = this.websocketclose;
     },

      websocketonopen() {
        console.log("WebSocket连接成功");
      },
      websocketonerror(e) { //错误
       console.log("WebSocket连接发生错误");
      },
      websocketonmessage(e){ //数据接收 
        const redata = JSON.parse(e.data);
         //注意:长连接我们是后台直接1秒推送一条数据,
//但是点击某个列表时,会发送给后台一个标识,后台根据此标识返回相对应的数据,
//这个时候数据就只能从一个出口出,所以让后台加了一个键,例如键为1时,是每隔1秒推送的数据,为2时是发送标识后再推送的数据,以作区分
        console.log(redata.value);
      },

      websocketsend(agentData){//数据发送
        this.websock.send(agentData);
      },

      websocketclose(e){ //关闭
        console.log("connection closed (" + e.code + ")");
     },
   },
  }
</script>
