Js WebSocket简单抽象类实现

/*** WebSocket客户端*/export abstract class WebSocketClient{protected ws:WebSocket;constructor(){}/*** 连接服务器* @param serverAddress 服务器地址*/public Connect(serverAddress:string){this.ws = new WebSocket("ws://"+serverAddress)//设置二进制类型this.ws.binaryType = "arraybuffer"; let self = this;this.ws.onopen = function (event) {self.onConnected()};this.ws.onmessage = function (event) {//console.info("recv"+event.data)self.onMessage(event.data)};this.ws.onerror = function (event) {self.onError()};this.ws.onclose = function (event) {self.onDisconnect()};}/*** 关闭websocket*/public Close(){this.ws.close()}/*** 判断是否连接到websocket服务器*/public isConnected():boolean{return (this.ws.readyState === WebSocket.OPEN)}/*** 发送数据* @param data 数据*/public sendMessage(data:any){if (this.isConnected()){this.ws.send(data)}else{console.error("WebSocket is closed!")}}/*** 当连接到服务器*/public abstract onConnected()/*** 当接受到数据*/public abstract onMessage(data:any)/*** 当出现错误时*/public abstract onError()/*** 当连接断开时*/public abstract onDisconnect()}
