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：

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

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;

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：

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：

* <ul>
* <p/>
* <li>Only one Java file</li>
* <li>Java 5 compatible</li>
* <li>Released as open source, Modified BSD licence</li>
* <li>No fixed config files, logging, authorization etc. (Implement yourself if you need them.)</li>
* <li>Supports parameter parsing of GET and POST methods (+ rudimentary PUT support in 1.25)</li>
* <li>Supports both dynamic content and file serving</li>
* <li>Supports file upload (since version 1.2, 2010)</li>
* <li>Supports partial content (streaming)</li>
* <li>Supports ETags</li>
* <li>Never caches anything</li>
* <li>Doesn't limit bandwidth, request time or simultaneous connections</li>
* <li>Default code serves files and shows all HTTP parameters and headers</li>
* <li>File server supports directory listing, index.html and index.htm</li>
* <li>File server supports partial content (streaming)</li>
* <li>File server supports ETags</li>
* <li>File server does the 301 redirection trick for directories without '/'</li>
* <li>File server supports simple skipping for files (continue download)</li>
* <li>File server serves also very long files without memory overhead</li>
* <li>Contains a built-in list of most common mime types</li>
* <li>All header names are converted lowercase so they don't vary between browsers/clients</li>

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。。
