[原创]CSDN免积分下载方法与原理小析（可制作面积分下载工具）

看到论坛上有人问csdn免积分下载器，实现原理，我看到的有两种。
1.注册新用户，送积分方式，用机器人自动注册用户名，例如，鬼哥免积分下载器。送积分后下载，这样对csdn资源是一种浪费。
2.利用csdn 接口未验证的bug进行下载。
例如：1.首先到下载区搜索你想要的资源 记下它的id
例如：http://download.csdn.net/detail/zrf139138/5293493 5293493为id
2.请求以下地址：http://download.csdn.net//index.php/rest/source/getsourceinfo/5298185 5293493为得到的id.  得到连接 

                                                                                                                  {"id":"5293493","title":"1500\u4e2a\u524d\u7aef\u5f00\u53d1\u5e38\u7528JavaScript\u7279\u6548","tag":["javascript","\u7279\u6548","\u5b9e\u4f8b","\u524d\u7aef"],"categoryid":"16007","sourcescore":"0","username":"zrf139138","sourcesize":"3489911","pubdate":"1366735880","updatetime":"2013-04-29 10:50:08","description":"1500\u4e2a\u524d\u7aef\u5f00\u53d1\u5e38\u7528JavaScript\u7279\u6548,\u5b9e\u4f8b\u8d85\u591a\uff0c\u7279\u6548\u5b9e\u7528\uff0c\u6b22\u8fce\u4e0b\u8f7d\u5b66\u4e60","isrecommended":"11","status":"2","filetype":"rar","originfile":"1500\u4e2a\u524d\u7aef\u5f00\u53d1\u5e38\u7528JavaScript\u7279\u6548.rar","fileaddr":"\/20130424\/295cc513f88b58de697799868e6a2904.rar","otherlink":"","fileaddr_prefix":"\/down10","md5":"cd58958bcefca6347db66817cd991a78","isrepeat":"0","download_num":"2499","sourcetype":"1","comment_num":"113","fav_num":"57","score_sum":"988","score_num":"231","operator":"zy3905324","operate_time":"1366768216","link":"\/detail\/zrf139138\/5293493","url":"http:\/\/dldx.csdn.net\/fd.php?i=676152934932432&"}                                      

分析后：http://dldx.csdn.net/fd.php?i=676152934932432& 就是下载地址。第三种方法还在研究暂时不公开，以后会介绍。
