今天老板交待任务最终完成了，感觉收获颇多，所以写一个关于它的记录，首先，看一下。老板的需求

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，当中HTML页面可能是用户使用PC訪问指定的html页面也有可能是移动端使用浏览器訪问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port，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。

详细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).尾随主服务常驻内存，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冊: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
比如：
http://serverhost/?cookie=123213&imei=31233213123
以上这步我们叫做一次绑定的完毕操作

以为我们是在移动端開始一个HttpServer的，所以要考虑一些额外的因素，比方耗电量
风险控制：使用灰度測试规则，并使用开关限制功能。

功耗风险：经过三台设备測试。电量消耗忽略不计（详细CPU使用时间在统计）。
 
2.Web JS：
1).载入页面载入后先从CDN载入一个静态的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。

(假设此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增加黑名单，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
同一时候考虑到开发效率，性能，和client的JS的契合度。
Node.js单台16核server，4节点，QPS经測试能到6k-8k。
较适合短频非堵塞的请求。
 
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高速应答。
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).移动端所须要的接口
接口一：Native App 对于本外网IP的注冊的请求。

接口二：Navtive App的绑定请求。

详细原理图：

上面解说了一下技术的实现方案，以下我们就来看一下，详细的实现技术

首先来看移动端的，我们须要建立一个HttpServer

我们可能知道在PC端建立一个Server非常easy，直接使用Tomcatserver就能够了。可是我们移动端不可能去搭建一个server的，那么我们该怎么办呢？我们能够在网上搜索一下关于怎样在手机中搭建一个WebServce，我们能够看到Apache已经帮我们做好了这件事了，他提供了一个jar。有对应的api。同一时候另一种技术就是老外有个人写好了一个类：NanoHttpd。我们仅仅须要看懂这个类。然后自己在编写一个类，继承这个类就可以。由于这个类是抽象的。

这两种搭建的Server原理都是非常easy的，就是建立一个Socket连接，这个和Tomcat是一样的。仅仅是他们将这样的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：

依照上面的技术方案。我们希望这个HttpServer常驻在一个服务中进行监听的。所以我们须要建立一个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() {@Overridepublic void onReceive(Context context, Intent intent) {if(intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)){AppListYPLog.e("DEMO","网络状态切换...");//注冊接口new Thread(){@Overridepublic void run(){//開始注冊register();}}.start();}}};@Overridepublic IBinder onBind(Intent arg0) {return null;}@Overridepublic 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());}//注冊广播IntentFilter filter = new IntentFilter();filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);registerReceiver(receiver, filter);}/*** 注冊ip地址* @return*/public boolean register(){//拼接參数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("注冊操作成功");//Toast.makeText(getApplicationContext(), "注冊成功", Toast.LENGTH_LONG).show();}else{AppListYPLog.e("注冊操作失败");//Toast.makeText(getApplicationContext(), "注冊失败", Toast.LENGTH_LONG).show();}} catch (ClientProtocolException e) {AppListYPLog.e("异常:"+e.getMessage()+",注冊失败");} catch (IOException e) {AppListYPLog.e("异常:"+e.getMessage()+",注冊失败");} catch(Exception e){AppListYPLog.e("异常:"+e.getMessage()+",注冊失败");}}return flag;}}

在这个服务中，我们開始的时候就进行注冊，上报一些信息：

imei:手机移动的标识

hs_ip:手机的HttpServer的地址和port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:注冊的时间戳

同一时候我们还注冊了一个监听网络变化的广播，这个是为了防止，開始的时候用户没有开启网络，一旦用户开启网路的时候，我们就开启监听而且进行注冊。

这里我们使用的监听port是3个。由于我们知道，port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port，在使用这个port之前要检測一下该port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：

首先我们须要下载Apache提供的jar包：

httpService.setHandlerResolver(reqistry); } @Override public void run() { AppListYPLog.i("Listening on port " + this.serversocket.getLocalPort()); AppListYPLog.i("Thread.interrupted = " + Thread.interrupted()); while (!Thread.interrupted()) { try { // 建立Http连接 Socket socket = this.serversocket.accept(); DefaultHttpServerConnection conn = new DefaultHttpServerConnection(); ipAddress = socket.getInetAddress().getHostAddress(); AppListYPLog.i("Incoming connection from " + socket.getInetAddress()); conn.bind(socket, this.params); //开启工作线程 Thread t = new WorkerThread(this.httpService, conn); t.setDaemon(true); t.start(); } catch (InterruptedIOException ex) { AppListYPLog.e("异常:InterruptedIOException"); break; } catch (IOException e) { AppListYPLog.e("I/O error initialising connection thread: " + e.getMessage()); break; } } } } /** * 后台工作线程 * @author weijiang204321 * */ static class WorkerThread extends Thread { private final HttpService httpservice; private final HttpServerConnection conn; public WorkerThread(final HttpService httpservice,final HttpServerConnection conn) { super(); this.httpservice = httpservice; this.conn = conn; } @Override public void run() { System.out.println("New connection thread"); HttpContext context = new BasicHttpContext(null); try { while (!Thread.interrupted() && this.conn.isOpen()) { this.httpservice.handleRequest(this.conn, context); } } catch (ConnectionClosedException ex) { System.err.println("Client closed connection"); } catch (IOException ex) { System.err.println("I/O error: " + ex.getMessage()); } catch (HttpException ex) { System.err.println("Unrecoverable HTTP protocol violation: "+ ex.getMessage()); } finally { try { this.conn.shutdown(); } catch (IOException ignore) { } } } } }

我们首先须要定义一个RequestHander用来处理请求的逻辑结果。同一时候我们须要建立一个HttpConnection,这里我们须要获取来訪者的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方法中进行上报完毕的动作，须要上报的參数为：

cookie:来訪者携带的cookie值(也就是Html页面中的cookie)

imei:手机的移动标识

visitor_ip:来訪者的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

手机端的HttpServer就搭建完毕了，以下我们要想測试的话。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);}}

移动端完毕操作的接口：

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。这里不须要连接在一个网段中，仅仅要在一个公网内就能够了，即他们两个能够ping通就能够。我这里在家里面測试的，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：

这样我们以下就能够来进行測试了，首先我们将Android应用部署到手机中，同一时候我们将Server启动，測试流程非常easy：我们尝试改变网络状态，将网路断开。在进行连接，打印Log例如以下：

这里我们看到注冊成功了，并且将手机的HttpServer的ip地址和监听port上报了

我们在Server查看上报的信息：

我们就能够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，这里另一个步骤就是要获取公网的ip地址

上面的注冊流程就走通了。以下我们看一下，完毕操作的測试：

我们在浏览器中訪问：

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

点击Click,我们看到控制台中Log信息

我们看到完毕操作，将cookie值和imei上报给Server端了，同一时候记录了来訪者的ip地址

我们在Server的控制台中看到信息打印：

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的时候另一种方法就是使用一个老外写的一个简单的类：

我们測试的时候须要自定义的类：

package com.sohu.nanohttpd;import android.app.Activity;
import android.os.Bundle;
import android.util.Log;public class MainActivity extends Activity {@Overrideprotected 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);}}

这里仅仅是做了一下拓展知识，两种方式搭建都能够的。可是明显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，这样的操作的价值是非常大的，未来假设用户在家里面进行上网的话，我们就能够将PC端和移动端进行紧密耦合在一起。相当于一个总体。

。这样我们对用户的行为就更加了解了。。
