Android中如何搭建一个WebServer

今天终于把老大交代的任务搞完了，感觉收获挺多的，所以就写一篇来记录一下吧，首先还是来看一下，老大们的需求

需求：

希望移动端的用户标识(IMEI)和HTML页面的用户标识(Cookie)连接起来，其中HTML页面可能是用户使用PC访问指定的html页面也有可能是移动端使用浏览器访问html页面

技术解决：

运用移动设备的系统特型，用Apps的Service监听本地的网络端口，当局域网内或本机的Html页面通过请求调用本地IP:Port时触发监听。Apps在将当前Html的Cookie和移动设备标识物发回服务端时，即实现了本次PC/Mobile Html页面的Cookie和移动设备的互相绑定。

具体实现方案之多端通信技术方案



各模块细节

1.Native App(移动端的app)：

1).跟随主服务常驻内存，在收到当前网络环境为Wifi事件后，启动HttpServer。

(当前网络切换成3G/2G等网络时关闭HttpServer)。

以上这步我们叫做注册:启动移动端的HttpServer的时候，我们会将移动设备的ip地址(内网地址)发送到指定的后台Server上

 

2).收到从Web来的http请求后，往Server发送绑定请求，这时候就将移动端的IMEI和HTML中的Cookie一起上传到指定的Server上

例如：

http://serverhost/?cookie=123213&imei=31233213123

以上这步我们叫做一次绑定的完成操作

以为我们是在移动端开始一个HttpServer的，所以要考虑一些额外的因素，比如耗电量

风险控制：使用灰度测试规则，并使用开关限制功能。

功耗风险：经过三台设备测试，电量消耗忽略不计（具体CPU使用时间在统计）。

 

2.Web JS：

1).加载页面加载后先从CDN加载一个静态的JS到此页面。

2).静态JS再请求Server 获取一段动态JS用以做本地Ping。

(如果此IP已有N次获取，则考虑>N的节点是一个大型公共网络，则把此公共IP加入黑名单，不再返回动态JS)

3).获得动态JS后直接Ping本地的HttpServer。

(Ping的IP/Port会随着动态JS一起下发)

这里我们是在Html页面中使用JS脚本来处理传递Cookie给移动端的功能。

3.Bridge Server：

1).Sever选型：Node.js

同时考虑到开发效率，性能，和client的JS的契合度。

Node.js单台16核服务器，4节点，QPS经测试能到6k-8k。

较适合短频非阻塞的请求。

 

2).数据存储：Redis

考虑到NativeApp的外网IP时效性，以及对于短频请求的快速应答。

以外网IP为Key，各个IP为Value。每天清理一次外网IP。

存储格式：{外网IP：{NativeApp IP/Port, .........}}



3).移动端所需要的接口

接口一：Native App 对于本外网IP的注册的请求。

接口二：Navtive App的绑定请求。



具体原理图：

上面讲解了一下技术的实现方案，下面我们就来看一下，具体的实现技术

首先来看移动端的，我们需要建立一个HttpServer

我们可能知道在PC端建立一个Server很简单，直接使用Tomcat服务器就可以了，但是我们移动端不可能去搭建一个服务器的，那么我们该怎么办呢？我们可以在网上搜索一下关于如何在手机中搭建一个WebServce，我们可以看到Apache已经帮我们做好了这件事了，他提供了一个jar，有相应的api，同时还有一种技术就是老外有个人写好了一个类：NanoHttpd，我们只需要看懂这个类，然后自己在编写一个类，继承这个类即可，因为这个类是抽象的。这两种搭建的Server原理都是很简单的，就是建立一个Socket连接，这个和Tomcat是一样的，只是他们将这种操作进行优化处理了，那么我们首先来看一下Apache给我们提供的这个HttpServer：

按照上面的技术方案，我们希望这个HttpServer常驻在一个服务中进行监听的，所以我们需要建立一个Service

package com.sohu.tests;
 
import java.io.IOException;
 
import org.apache.http.client.ClientProtocolException;
 
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.net.ConnectivityManager;
import android.os.IBinder;
import android.util.Log;
 
public class SocketService extends Service {
 
	private int port = Consts.defaultPort;
 
	//网络开关状态改变的监听
	private BroadcastReceiver receiver = new BroadcastReceiver() {
		@Override
		public void onReceive(Context context, Intent intent) {
			if(intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)){
				AppListYPLog.e("DEMO","网络状态切换...");
				//注册接口
				new Thread(){
					@Override
					public void run(){
						//开始注册
						register();
					}
				}.start();
			}
		}
	};
 
	@Override
	public IBinder onBind(Intent arg0) {
		return null;
	}
 
	@Override
	public void onCreate() {
		super.onCreate();
		Log.v("23233", "Complete");
 
		Utils.init(this);
 
		//开启监听端口
		HttpServer hs = new HttpServer();
		try{
			AppListYPLog.i("监听开启...");
			for(int i=0;i<Consts.portAry.length;i++){
				if(Utils.checkPort(Consts.portAry[i])){
					port = Consts.portAry[i];
					break;
				}
			}
			hs.execute(port);
			register();
		}catch(Exception e){
			AppListYPLog.e("异常:"+e.getMessage());
		}
 
		//注册广播
		IntentFilter filter = new IntentFilter();
		filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
		registerReceiver(receiver, filter);
 
	}
 
	/**
	 * 注册ip地址
	 * @return
	 */
	public boolean register(){
		//拼接参数
        StringBuilder param = new StringBuilder();
        param.append("imei=");
        param.append(Utils.getImeiInfo());
        param.append("&hs_ip=");
        param.append(Utils.getLocalHostIp()+":"+port);
        param.append("&route_mac=");
        param.append(Utils.getRouteMac());
        param.append("&route_ssid=");
        param.append(Utils.getRouteSSID());
        param.append("&timetag=");
        param.append(System.currentTimeMillis()+"");
 
        boolean flag = false;
 
		 //上报数据
        if(Utils.checkNetWorkState()){
        	try {
				flag = NetUtils.uploadRequest(Consts.registerUrl, param.toString());
				if(flag){
					AppListYPLog.i("注册操作成功");
					//Toast.makeText(getApplicationContext(), "注册成功", Toast.LENGTH_LONG).show();
				}else{
					AppListYPLog.e("注册操作失败");
					//Toast.makeText(getApplicationContext(), "注册失败", Toast.LENGTH_LONG).show();
				}
			} catch (ClientProtocolException e) {
				AppListYPLog.e("异常:"+e.getMessage()+",注册失败");
			} catch (IOException e) {
				AppListYPLog.e("异常:"+e.getMessage()+",注册失败");
			} catch(Exception e){
				AppListYPLog.e("异常:"+e.getMessage()+",注册失败");
			}
        }
 
        return flag;
	}
 
}

在这个服务中，我们开始的时候就进行注册，上报一些信息：

imei:手机移动的标识

hs_ip:手机的HttpServer的地址和端口号

route_mac:手机连接的路由器的mac地址

route_ssid:手机连接的路由器的ssid

timetag:注册的时间戳

同时我们还注册了一个监听网络变化的广播，这个是为了防止，开始的时候用户没有开启网络，一旦用户开启网路的时候，我们就开启监听并且进行注册。

这里我们使用的监听端口是3个，因为我们知道，端口最大的是655535，0-1024是系统使用的，所以我们就使用了三个备用的端口，在使用这个端口之前要检测一下该端口有没有被占用，这里我们就使用Socket探针技术。

再来看一下最核心的HttpServer的实现：

首先我们需要下载Apache提供的jar包：

我们首先需要定义一个RequestHander用来处理请求的逻辑结果，同时我们需要建立一个HttpConnection,这里我们需要获取来访者的ip地址，所以我们定义了一个全局的变量ipAddress,然后在WebServiceHandler类中的handle方法中进行上报完成的动作，需要上报的参数为：

cookie:来访者携带的cookie值(也就是Html页面中的cookie)

imei:手机的移动标识

visitor_ip:来访者的ip地址

local_ip:本机的ip地址

route_mac:手机连接的路由器的地址

route_ssid:手机连接的路由器的ssid

timetag:上报的时间戳

测试的Demo:

package com.sohu.tests;
 
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
 
public class Main extends Activity {
 
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.mainlay);
		startService(new Intent(this, SocketService.class));
	}
 
}

手机端的HttpServer就搭建完成了，下面我们要想测试的话，就必须在搭建一个Server端，我们这里就简单的建立一个Servlet：

移动端进行注册的接口：

package com.weijiang.httpserver;
 
import java.io.IOException;
import java.util.Date;
 
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
 
public class RegisterServlets extends HttpServlet {
 
	private static final long serialVersionUID = 1L;
 
	protected void doGet(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {
		System.out.println("imei:"+req.getParameter("imei"));
		System.out.println("hs_ip:"+req.getParameter("hs_ip"));
		System.out.println("route_mac:"+req.getParameter("route_mac"));
		System.out.println("route_ssid:"+req.getParameter("route_ssid"));
		System.out.println("timetag："+new Date(Long.parseLong(req.getParameter("timetag"))));
	}
 
	protected void doPost(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {
		doGet(req,resp);
	}
 
}

移动端完成操作的接口：

package com.weijiang.httpserver;
 
import java.io.IOException;
import java.util.Date;
 
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
 
public class FinishServlets extends HttpServlet {
 
	private static final long serialVersionUID = 1L;
 
	protected void doGet(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {
		System.out.println("cookie:"+req.getParameter("cookie"));
		System.out.println("imei:"+req.getParameter("imei"));
		System.out.println("visitor_ip:"+req.getParameter("visitor_ip"));
		System.out.println("local_ip:"+req.getParameter("local_ip"));
		System.out.println("route_mac:"+req.getParameter("route_mac"));
		System.out.println("route_ssid："+req.getParameter("route_ssid"));
		System.out.println("timetag："+new Date(Long.parseLong(req.getParameter("timetag"))));
	}
 
	protected void doPost(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {
		doGet(req,resp);
	}
 
}

模拟携带有cookie值的Html页面

<body>
    <a href='http://192.168.1.109:23021?cookie=123456'>Click</a>
</body>

这里就是为了简单的模拟，所以直接随便写了一个cookie值

我们将PC和手机进行联网，这里不需要连接在一个网段中，只要在一个公网内就可以了，即他们两个可以ping通就可以，我这里在家里面测试的，用的是自己的路由器，所以一定是在一个网段中，我们查看PC的ip地址：

手机端的ip地址：

这样我们下面就可以来进行测试了，首先我们将Android应用部署到手机中，同时我们将Server启动，测试流程很简单：我们尝试改变网络状态，将网路断开，在进行连接，打印Log如下：

这里我们看到注册成功了，而且将手机的HttpServer的ip地址和监听端口上报了

我们在Server查看上报的信息：

我们就可以将手机的的内网地址进行保存，这里我们要注意在前面我们说到，这里还有一个步骤就是要获取公网的ip地址

上面的注册流程就走通了，下面我们看一下，完成操作的测试：

我们在浏览器中访问：

http://localhost:8080/HttpServer/index.jsp

点击Click,我们看到控制台中Log信息

我们看到完成操作，将cookie值和imei上报给Server端了，同时记录了来访者的ip地址

我们在Server的控制台中看到打印信息：

这样我们就将手机的imei和html页面的cookie值进行绑定了。。

前面我们说到了搭建移动端的Server的时候还有一种方法就是使用一个老外写的一个简单的类：

我们测试的时候需要自己定义的类：

package com.sohu.nanohttpd;
 
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
 
public class MainActivity extends Activity {
 
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
 
		NanoHTTPD nanoHttpd = new MyNanoHTTPD("127.0.0.1",23456);
		try{
			nanoHttpd.start();
		}catch(Exception e){
			e.printStackTrace();
		}
 
		Log.e("DEMO",nanoHttpd.isAlive()+"");
 
	}
 
}
 
class MyNanoHTTPD extends NanoHTTPD{
 
	public MyNanoHTTPD(int port) {
		super(port);
	}
 
	public MyNanoHTTPD(String hostName,int port){
		super(hostName,port);
	}
 
	 public Response serve(IHTTPSession session) {
		 Method method = session.getMethod();
		 Log.e("DEMO","Method:"+method.toString());
		 if(NanoHTTPD.Method.GET.equals(method)){
			 //get方式
			 String queryParams = session.getQueryParameterString();
			 Log.e("DEMO","params:"+queryParams);
		 }else if(NanoHTTPD.Method.POST.equals(method)){
			 //post方式
		 }
		 return super.serve(session);
	 }
 
}

这里只是做了一下拓展知识，两种方式搭建都可以的，但是明显Apache的功能强大一点。。

总结：上面就是将PC端的Cookie和移动端的imei进行绑定的操作，这种操作的价值是很大的，未来如果用户在家里面进行上网的话，我们就可以将PC端和移动端进行紧密耦合在一起，相当于一个整体。。这样我们对用户的行为就更加了解了。。
