服务器评测
在Linux下资源下载的速度长期受限，ed2k，torrent什么都木有速度，坑爹呀，自从购买了迅雷VIP的服务，可以直接以http形式来从迅雷服务器内下载自己托迅雷下载的东西，而且如果你这个资源别人下载过的话，你就不用再次下载了，迅雷马上提示你这个任务已经完成了。
至于其他的，用过的人都知道了，也不再细说。如果windows平台配合迅雷客户端用迅雷VIP的话，这个脚本也没有啥意义了（因为客户端更人性化^_^，当然占用资源也不少，嘿嘿），所以前提是你的OS要是Linux，然后使用迅雷离线的web界面。
由于firefox下载迅雷离线的东西存在这样几个问题，比如文件名中文乱码，要自己改（暗骂编码ing），不支持断点续传（我挂过几次，不过无奈重新下载了T_T），迅雷在点击下载的时候，响应慢死了，好久才跳出窗口。
出于这几个原因，我就去研究了下PT酱的那个离线下载的脚本，然后根据自己的需要重新写如下：

用法如下，有两个东西要解释下：
第一个，user_task.htm就是你的迅雷任务页面，在Firefox可以用Ctrl+S进行保存下来，下载信息都在里面;
第二个，cookie file就是你的cookie文件，这个是给wget用的，这个文件你可以用firefox的export cookie这个插件获取（一般重新登陆之后就需要再次export一次，因为这个时候旧的cookie已经失效了），其他浏览器请自行问google;output dir就是你的下载保存路径，其他就不说了，不明白可以联系我。
(virpython2)[roowe@Arch mytools]$ ./thuner_xl_with_wget.py -h
usage: thuner_xl_with_wget.py [-h] [-p [P]] [-c [C]] [-o [O]] [-b] [-q] [-a]
Thuner li xian with wget
optional arguments:
-h, —help show this help message and exit
-p [P] load page file (default: ~/user_task.htm)
-c [C] load cookie file (default: ~/cookies.txt)
-o [O] output dir (default: ~/Downloads)
-b bt files only (default: False)
-q quiet, only log to file. (default: False)
-a download with aria2c (default: False)
执行下面的命令即可：
(virpython2)[roowe@Arch mytools]$ ./thuner_xl_with_wget.py -o /home/ftpusers/ics
