Vue中使用websocket
<template><div class="test">websocket demo</div>
</template>
<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
let wsuri = "ws://echo.websocket.org/";
this.websock = new WebSocket(wsuri);
this.websock.onopen = this.websocketonopen;
this.websock.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>
