13-6-25 移动服务器的实现之连接的建立（二）

在很多产业中，移动服务器配合android系统来实现小型服务器构架越来越成为我们的议题，尤其是物联网的发展，IPV6的推出。智能家居对移动服务器的需要更是千丝万缕，毕竟一台成熟的服务器价格还是不菲的，不适合广泛的每个家庭来安装。所以我提出了移动服务器的议题，来解决我们小访问量的服务器构架。

      小型服务器的构架原理是什么，框架结构又如何，通信机制是什么，实现办法该怎样，都是我们遇上的问题。这里我会一一记录我构架的服务器的过程，供大家参考。

服务器的框架：采用apache技术，通信采用http的GET方法，POST方法我没有搞通。

1.效果演示

效果为：

 

                                                   未打开wifi获取的效果

                                                  打开wifi获取的IP地址

                                       浏览器通过get方式请求服务器获取的内容。

2.程序讲解

2.1 主线程开启service服务

@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);initViews();intent = new Intent(this, WebService.class);Log.i(TAG, "------->>>"+"初始化完毕"+intent.toString());}private void initViews() {toggleBtn = (ToggleButton) findViewById(R.id.togbtnOpen);toggleBtn.setOnCheckedChangeListener(this);urlText = (TextView) findViewById(R.id.txtUrl);}

处理toggleButton改变触发

@Overridepublic void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {if (isChecked) {String ip = getLocalIpAddress();if (ip == null) {urlText.setText("");} else {startService(intent);Log.i(TAG, "------->>>"+"WebService起动");urlText.setText("http://" + ip + ":" + WebService.PORT + "/");}} else {stopService(intent);Log.i(TAG, "------->>>"+"WebService关闭"+intent.toString());urlText.setText("");}}

获取当前IP地址

public String getLocalIpAddress(){WifiManager wifimanager = (WifiManager)this.getSystemService(Context.WIFI_SERVICE);WifiInfo wifiinfo = (WifiInfo)wifimanager.getConnectionInfo();try {  int i = wifiinfo.getIpAddress();//返回IP 地址return (i&0xff)+"."+((i>>8)&0xff)+"."+((i>>16)&0xff)+"."+((i>>24)&0xff);    } catch (Exception ex) {          ex.printStackTrace();    }      return null;  }

2.在service任务中加入server处理

public class WebService extends Service {public static final int PORT = 7766;public static final String TAG = "WebService";private WebServer webServer;@Overridepublic IBinder onBind(Intent intent) {// TODO Auto-generated method stubreturn null;}@Overridepublic void onCreate() {super.onCreate();webServer = new WebServer(PORT);}@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {webServer.setDaemon(true);webServer.start();return super.onStartCommand(intent, flags, startId);}@Overridepublic void onDestroy() {webServer.close();super.onDestroy();}}

3.做WebServer处理程序

public class WebServer extends Thread {public static final String TAG = "WebService";private int port;private boolean isLoop = false;public WebServer(int port) {super();this.port = port;}@Overridepublic void run() {ServerSocket serverSocket = null;try {Log.i(TAG, "coming in!!");// 创建服务器套接字serverSocket = new ServerSocket(port);// 创建HTTP协议处理器BasicHttpProcessor httpproc = new BasicHttpProcessor();// 增加HTTP协议拦截器httpproc.addInterceptor(new ResponseDate());httpproc.addInterceptor(new ResponseServer());httpproc.addInterceptor(new ResponseContent());httpproc.addInterceptor(new ResponseConnControl());// 创建HTTP服务HttpService httpService = new HttpService(httpproc,new DefaultConnectionReuseStrategy(),new DefaultHttpResponseFactory());// 创建HTTP参数HttpParams params = new BasicHttpParams();params.setIntParameter(CoreConnectionPNames.SO_TIMEOUT, 5000).setIntParameter(CoreConnectionPNames.SOCKET_BUFFER_SIZE,8 * 1024).setBooleanParameter(CoreConnectionPNames.STALE_CONNECTION_CHECK, false).setBooleanParameter(CoreConnectionPNames.TCP_NODELAY, true).setParameter(CoreProtocolPNames.ORIGIN_SERVER,"WebServer/1.1");// 设置HTTP参数httpService.setParams(params);// 创建HTTP请求执行器注册表HttpRequestHandlerRegistry reqistry = new HttpRequestHandlerRegistry();reqistry.register("*"+"AfangCtrl", new AfangCtrl());reqistry.register("*"+"CameraCtrl", new CameraCtrl());reqistry.register("*"+"LightCtrl", new LightCtrl());reqistry.register("*"+"TvCtrl", new TvCtrl());// 设置HTTP请求执行器httpService.setHandlerResolver(reqistry);/* 循环接收各客户端 */isLoop = true;while (isLoop && !Thread.interrupted()) {// 接收客户端套接字Socket socket = serverSocket.accept();// 绑定至服务器端HTTP连接DefaultHttpServerConnection conn = new DefaultHttpServerConnection();conn.bind(socket, params);// 派送至WorkerThread处理请求Thread t = new WorkerThread(httpService, conn);t.setDaemon(true); // 设为守护线程t.start();}} catch (IOException e) {isLoop = false;e.printStackTrace();} finally {try {if (serverSocket != null) {serverSocket.close();}} catch (IOException e) {}}}public void close() {isLoop = false;}}

4.对LightCtrl进行简单描述

 当前类要继承HttpRequestHandler类，做handler实现请求的处理

public class LightCtrl implements HttpRequestHandler {private static final String TAG = "HttpJsonlogin";public LightCtrl(){}@Overridepublic void handle(HttpRequest request, HttpResponse response,HttpContext context) throws HttpException, IOException {RequestLine requestLine = request.getRequestLine();String method=requestLine.getMethod();if("GET".equals(method)){doGet(request, response);}else{Log.i(TAG, "method is error:"+method.toString());  }}/**************************************************************** * urlCmd格式：http://loaclhost:port/DEVICE?device=num&operation=open(close)&clientId=phone * @param request * @param response */public void doGet(HttpRequest request, HttpResponse response){response.setStatusCode(HttpStatus.SC_OK);//响应成功response.setHeader("Content-Type", "text/json");response.setHeader("Content-Type", "charset=gbk");JSONObject json = new JSONObject();//************解析参数*************************************String urlCmd = request.getRequestLine().getUri();int a = urlCmd.indexOf("device");a=a+7;int b = urlCmd.indexOf("&",a);String device = urlCmd.substring(a, b);a = urlCmd.indexOf("operation");a=a+10;b = urlCmd.indexOf("&",a);String operation = urlCmd.substring(a, b);a = urlCmd.indexOf("clientId");a=a+9;b = urlCmd.length();String clientId = urlCmd.substring(a, b);Log.i(TAG, "请求命令为："+device+operation+clientId);//根据命令做出响应StringEntity entity = null;try {json.put("device", device);json.put("operation", operation);json.put("clientId", clientId);json.put("result", "ok");Log.i(TAG,"响应JSON数据为："+json.toString());entity = new StringEntity(json.toString(),"UTF-8");} catch (JSONException e) {e.printStackTrace();} catch (UnsupportedEncodingException e) {// TODO Auto-generated catch blocke.printStackTrace();}response.setEntity(entity);}}
