1.判断浏览器是否支持WebSocket,发起WebSocket连接
- if(typeof(WebSocket) === 'undefined'){
- alert("您的浏览器不支持在线聊天")
- }else{
- //初始化WebSocket
- _this.socket = new WebSocket("wss://"+你的地址)
- _this.socket.onopen = function(){
- console.log("连接成功")
- heartCheck.reset().start()
- }
- }
2.增加心跳检测,并在WebSocket连接成功是调用该方法
- let _this = this
- var heartCheck = {
- timeout:5000,
- timeoutObj:null,
- reset:function(){
- clearInterval(this.timeoutObj)
- return this;
- },
- start:function(){
- this.timeoutObj = setInterval(function(){
- _this.socket.send('heartbeat')
- console.log("给服务器发送:heartbeat")
- },this.timeout)
- }
- }
3.接收到服务器的消息
- _this.socket.onmessage = function(event){
- console.log("接收到服务器消息:"+event.data)
- }
4.关闭时聊天时销毁WebSocket链接
this.socket.close()
完整代码
- init(){
- if(typeof(WebSocket) === 'undefined'){
- alert("您的浏览器不支持在线聊天")
- }else{
- let _this = this
- var heartCheck = {
- timeout:5000,
- timeoutObj:null,
- reset:function(){
- clearInterval(this.timeoutObj)
- return this;
- },
- start:function(){
- this.timeoutObj = setInterval(function(){
- _this.socket.send('heartbeat')
- console.log("给服务器发送:heartbeat")
- },this.timeout)
- }
- }
- _this.socket = new WebSocket("wss://" + )
- _this.socket.onopen = function(){
- console.log("连接成功")
- heartCheck.reset().start()
- }
- _this.socket.onmessage = function(event){
- console.log("接收到服务器消息:"+event.data)
-
- }
- }
- }
