【详细超简单】如何使用WebSocket链接

created：

this.contactSocket()

 methods

	  contactSocket(){
		  let webSocket = null;
		  let socketOpen = false;
		  let that=this
		  if ("WebSocket" in window) {
		    webSocket = new WebSocket("ws://后台给的url");
		    webSocket.onopen = function (){
		      console.log("连接成功！");
			 webSocket.send(that.token)
		      socketOpen = true
			  
		    };
		    webSocket.onmessage = function (evt) {
		      var received_msg = evt.data;
		      console.log("接受消息：" + received_msg);
		    };
		    webSocket.onclose = function () {
		      console.log("连接关闭！");
			  that.reconnect()
		    };
		    webSocket.onerror = function () {
		      console.log("连接异常！");
		    };
		  }
	  },
	  // 重连
	  reconnect(){
		  console.log('重新连接')
		  setInterval(this.contactSocket(), 10000)
		  
	  },

直接换好链接调用就行了，非常简单
