Android中如何搭建一個WebServer

今天終於把老大交代的任務搞完了，感覺收獲挺多的，所以就寫一篇來記錄一下吧，首先還是來看一下，老大們的需求

需求：

希望移動端的用戶標識(IMEI)和HTML頁面的用戶標識(Cookie)連接起來，其中HTML頁面可能是用戶使用PC訪問指定的html頁面也有可能是移動端使用浏覽器訪問html頁面

技術解決：

運用移動設備的系統特型，用Apps的Service監聽本地的網絡端口，當局域網內或本機的Html頁面通過請求調用本地IP:Port時觸發監聽。Apps在將當前Html的Cookie和移動設備標識物發回服務端時，即實現了本次PC/Mobile Html頁面的Cookie和移動設備的互相綁定。

具體實現方案之多端通信技術方案

各模塊細節
1.Native App(移動端的app)：
1).跟隨主服務常駐內存，在收到當前網絡環境為Wifi事件後，啟動HttpServer。
(當前網絡切換成3G/2G等網絡時關閉HttpServer)。

以上這步我們叫做注冊:啟動移動端的HttpServer的時候，我們會將移動設備的ip地址(內網地址)發送到指定的後台Server上

2).收到從Web來的http請求後，往Server發送綁定請求，這時候就將移動端的IMEI和HTML中的Cookie一起上傳到指定的Server上
例如：
http://serverhost/?cookie=123213&imei=31233213123
以上這步我們叫做一次綁定的完成操作

以為我們是在移動端開始一個HttpServer的，所以要考慮一些額外的因素，比如耗電量
風險控制：使用灰度測試規則，並使用開關限制功能。
功耗風險：經過三台設備測試，電量消耗忽略不計（具體CPU使用時間在統計）。

2.Web JS：
1).加載頁面加載後先從CDN加載一個靜態的JS到此頁面。

2).靜態JS再請求Server 獲取一段動態JS用以做本地Ping。
(如果此IP已有N次獲取，則考慮>N的節點是一個大型公共網絡，則把此公共IP加入黑名單，不再返回動態JS)

3).獲得動態JS後直接Ping本地的HttpServer。
(Ping的IP/Port會隨著動態JS一起下發)

這裡我們是在Html頁面中使用JS腳本來處理傳遞Cookie給移動端的功能。

3.Bridge Server：
1).Sever選型：Node.js
同時考慮到開發效率，性能，和client的JS的契合度。
Node.js單台16核服務器，4節點，QPS經測試能到6k-8k。
較適合短頻非阻塞的請求。

2).數據存儲：Redis
考慮到NativeApp的外網IP時效性，以及對於短頻請求的快速應答。
以外網IP為Key，各個IP為Value。每天清理一次外網IP。
存儲格式：{外網IP：{NativeApp IP/Port, .........}}

3).移動端所需要的接口
接口一：Native App 對於本外網IP的注冊的請求。
接口二：Navtive App的綁定請求。

具體原理圖：

上面講解了一下技術的實現方案，下面我們就來看一下，具體的實現技術

首先來看移動端的，我們需要建立一個HttpServer

我們可能知道在PC端建立一個Server很簡單，直接使用Tomcat服務器就可以了，但是我們移動端不可能去搭建一個服務器的，那麼我們該怎麼辦呢？我們可以在網上搜索一下關於如何在手機中搭建一個WebServce，我們可以看到Apache已經幫我們做好了這件事了，他提供了一個jar，有相應的api，同時還有一種技術就是老外有個人寫好了一個類：NanoHttpd，我們只需要看懂這個類，然後自己在編寫一個類，繼承這個類即可，因為這個類是抽象的。這兩種搭建的Server原理都是很簡單的，就是建立一個Socket連接，這個和Tomcat是一樣的，只是他們將這種操作進行優化處理了，那麼我們首先來看一下Apache給我們提供的這個HttpServer：<喎?/kf/ware/vc/" target="_blank" class="keylink">vcD4KPHA+sLTV1cnPw+a1xLy8yvW3vbC4o6zO0sPHz6PN+9XiuPZIdHRwU2VydmVys6PXpNTa0ru49rf+zvHW0L340NC84Mz9tcSjrMv50tTO0sPH0OjSqr2owaLSu7j2U2VydmljZTwvcD4KPHA+PHByZSBjbGFzcz0="brush:java;">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; //網絡開關狀態改變的監聽 private BroadcastReceiver receiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if(intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)){ AppListYPLog.e("DEMO","網絡狀態切換..."); //注冊接口 new Thread(){ @Override public void run(){ //開始注冊 register(); } }.start(); } } }; @Override public IBinder onBind(Intent arg0) { return null; } @Override public void onCreate() { super.onCreate(); Log.v("23233", "Complete"); Utils.init(this); //開啟監聽端口 HttpServer hs = new HttpServer(); try{ AppListYPLog.i("監聽開啟..."); for(int i=0;i在這個服務中，我們開始的時候就進行注冊，上報一些信息：

imei:手機移動的標識

hs_ip:手機的HttpServer的地址和端口號

route_mac:手機連接的路由器的mac地址

route_ssid:手機連接的路由器的ssid

timetag:注冊的時間戳

同時我們還注冊了一個監聽網絡變化的廣播，這個是為了防止，開始的時候用戶沒有開啟網絡，一旦用戶開啟網路的時候，我們就開啟監聽並且進行注冊。

這裡我們使用的監聽端口是3個，因為我們知道，端口最大的是655535，0-1024是系統使用的，所以我們就使用了三個備用的端口，在使用這個端口之前要檢測一下該端口有沒有被占用，這裡我們就使用Socket探針技術。

再來看一下最核心的HttpServer的實現：

首先我們需要下載Apache提供的jar包：

        }  
    } 
    
}  

我們首先需要定義一個RequestHander用來處理請求的邏輯結果，同時我們需要建立一個HttpConnection,這裡我們需要獲取來訪者的ip地址，所以我們定義了一個全局的變量ipAddress,然後在WebServiceHandler類中的handle方法中進行上報完成的動作，需要上報的參數為：

cookie:來訪者攜帶的cookie值(也就是Html頁面中的cookie)

imei:手機的移動標識

visitor_ip:來訪者的ip地址

local_ip:本機的ip地址

route_mac:手機連接的路由器的地址

route_ssid:手機連接的路由器的ssid

timetag:上報的時間戳

測試的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));
	}
	
}

手機端的HttpServer就搭建完成了，下面我們要想測試的話，就必須在搭建一個Server端，我們這裡就簡單的建立一個Servlet：

移動端進行注冊的接口：

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);
	}

}

移動端完成操作的接口：

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);
	}

}

模擬攜帶有cookie值的Html頁面

    Click

這裡就是為了簡單的模擬，所以直接隨便寫了一個cookie值

我們將PC和手機進行聯網，這裡不需要連接在一個網段中，只要在一個公網內就可以了，即他們兩個可以ping通就可以，我這裡在家裡面測試的，用的是自己的路由器，所以一定是在一個網段中，我們查看PC的ip地址：

手機端的ip地址：

這樣我們下面就可以來進行測試了，首先我們將Android應用部署到手機中，同時我們將Server啟動，測試流程很簡單：我們嘗試改變網絡狀態，將網路斷開，在進行連接，打印Log如下：

這裡我們看到注冊成功了，而且將手機的HttpServer的ip地址和監聽端口上報了

我們在Server查看上報的信息：

我們就可以將手機的的內網地址進行保存，這裡我們要注意在前面我們說到，這裡還有一個步驟就是要獲取公網的ip地址

上面的注冊流程就走通了，下面我們看一下，完成操作的測試：

我們在浏覽器中訪問：

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

點擊Click,我們看到控制台中Log信息

我們看到完成操作，將cookie值和imei上報給Server端了，同時記錄了來訪者的ip地址

我們在Server的控制台中看到打印信息：

這樣我們就將手機的imei和html頁面的cookie值進行綁定了。。

前面我們說到了搭建移動端的Server的時候還有一種方法就是使用一個老外寫的一個簡單的類：

我們測試的時候需要自己定義的類：

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);
	 }
	
	
}

這裡只是做了一下拓展知識，兩種方式搭建都可以的，但是明顯Apache的功能強大一點。。

總結：上面就是將PC端的Cookie和移動端的imei進行綁定的操作，這種操作的價值是很大的，未來如果用戶在家裡面進行上網的話，我們就可以將PC端和移動端進行緊密耦合在一起，相當於一個整體。。這樣我們對用戶的行為就更加了解了。。
