修改两处代码即可使用，一个是请求后台的地址，还有一个是发送给后台的参数，(注意：webstock中只能发送字符串)

created() {

this.initWebSocket();

},

destroyed() {

this.websock.close();//离开路由之后断开websocket连接

},

methods: {

initWebSocket(){//初始化weosocket(必须)

const wsuri = "后台给你的请求地址"; //请根据实际项目需要进行修改

this.websock = new WebSocket(wsuri); //新建一个webstock对象

this.websock.onmessage = this.websocketonmessage;

this.websock.onopen = this.websocketonopen;

this.websock.onerror = this.websocketonerror;

this.websock.onclose = this.websocketclose;

},

websocketonopen(){//websocket连接后发送数据(send发送)

let actions = {你要发送给后台的参数}; //请根据实际项目需要进行修改

this.websocketsend(JSON.stringify(actions));

},

websocketonerror(){//连接建立失败重连

this.initWebSocket();

},

websocketonmessage(e){ //数据接收

this.redata = JSON.parse(e.data).data;

console.log(this.redata);

},

websocketsend(Data){//数据发送

this.websock.send(Data);

},

websocketclose(e){ //关闭

console.log('断开连接',e);

},

},
