简单的 websocket

项目由于要实现一些自主定位推送，tcp协议后台不知怎么搭不上，决定还是换成http协议  用websocket 去实现推送。当时我是懵的，没去了解过这个websocket，和同事花了一下时间搞懂了一部分，深入的东西项目里没用到就先过了。

           需要的jar  包                        Java-WebSocket-1.3.1-SNAPSHOT.jar 

直接上代码

在Application中初始化 并连接

// websockettry {uri = new URI("服务器ip或者域名"); //例如：http://rdp.7wa.com:5503Draft_17 draft = new Draft_17();websocket = QppWebsocket.webSocket(uri, new Draft_17(), this);Field field = websocket.getClass().getDeclaredField("engine");field.set(websocket, new MyWebSocketImpl(websocket, draft));} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}

清单文件要记得给广播进行注册

  <!-- websocket -->         <receiver             android:name="com.qpp.websocketPush.ClientReceiver"             >            <intent-filter android:priority="1000"                >                <action android:name="com.qpbox"/>            </intent-filter>        </receiver>

如果是要用户登录时客户端发送消息到服务器后服务器对登录用户进行针对推送 

在登录成功的方法里调用

QPPApplication.websocket.connectBlocking();QPPApplication.websocket.sendMsg(map_2_json(login("14778327", "0", "62236824340")));

客户端发送什么唯一标识来给服务端 请行约定好即可。 我这里是推荐手机标识符+时间戳+随机数；

如果有更多优化会继续更新的。代码全在这里。
