通过抓包获取QQ空间相册的真实地址，实现空间相册下载。

在网上找过相关的资料，都不是太全~有些缺漏。所有自己根据网上的再结合自己的修改了下。

1.通过HttpAnalyzerStdV5 分析QQ空间相册的真实地址。一下就是空间相册的地址：

之前在网上看见只有一个地址，但是通过我的分析，貌似会有很大的问题。比如：某个人的空间相册有些是有设置密码的。也有不设置密码的，那么就无法下载。因为这类的相册是通过另外一个URL解析的。

 
      1 
       private static final String albumbase1 = "http://alist.photo.qq.com/fcgi-bin/fcg_list_album?uin=";//如果没有设置密保的相册是通过这个地址访问的  
     
      2 
       private static final String albumbase2 = "http://xalist.photo.qq.com/fcgi-bin/fcg_list_album?uin=";//设置密保的相册是通过这个地址访问的  
     
      3 
       
      4 
      //private static final String photobase = "http://alist.photo.qq.com/fcgi-bin/fcg_list_photo?uin="; 
     
      5 
       private static final String photobase1 = "http://plist.photo.qq.com/fcgi-bin/fcg_list_photo?uin=";  
     
      6 
       private static final String photobase2 = "http://xaplist.photo.qq.com/fcgi-bin/fcg_list_photo?uin=";

2.程序的main方法：

1.albums集合是所有相册的集合。

2.主要是两个方法一个是得到集合getAlbums 一个是保存相册的 savePhoto

 
      01 
       public static void main(String[] args) {  
     
      02 
           PhotoDownLoad pdl = new PhotoDownLoad();  
     
      03 
           String qq = "1315404564";  
     
      04 
           albums = pdl.getAlbums(qq, albumbase1);//先传一个地址进去要是找到不再分析另外一个地址  
     
      05 
           if (albums == null || albums.size() == 0) {  
     
      06 
               albums = pdl.getAlbums(qq, albumbase2);  
     
      07 
           }  
     
      08 
           if (albums == null || albums.size() == 0) {  
     
      09 
               System.out.println("没有获取到相册");  
     
      10 
           }  
     
      11 
           int len = albums.size();  
     
      12 
           System.out.println("相册信息获取成功,用户共有" + len + "个相册.");  
     
      13 
           for (int i = 0; i < len; i++) { // 考虑到相册数量不会很多,相册采用顺序下载，不使用异步下载  
     
      14 
               System.out.println("开始下载第" + (i + 1) + "个相册...");  
     
      15 
               pdl.savePhoto(i, qq);  
     
      16 
               pdl.curIndex = 0;  
     
      17 
               System.out.println("第" + (i + 1) + "个相册下载完成.");  
     
      18 
           }  
     
      19 
      }
