原理就是第一次登陆时候获取的cookie，里面包含这验证码信息。使用这个cookie去获取验证码，然后手动输入，然后post给网站，就登陆成功了。（http是无状态的）

之后输出view/mh.php文件就能看到得到整个文件，至于显示的出错的原因： 

js文件内有些返回值是相对路径，那么get的路径就会错误，例如：如果我的本地配置域名是www.first.com，那么get的相对路径默认是我本地域名了，会导致get数据出错。解决办法是将本地域名配置成跟藏宝阁同一个域名，这样就会省去很多改动。

      还有一个显示乱码问题，看了很多天js代码，没有发现错误。最后，是将js文件的拷到本地，使用本地的js文件，这样中文显示乱码就解决掉了，原因还没有想通。
