/*
一个简单的新浪微搏curl模拟登录类. 来源: http://chenall.net/post/sina_curl_login/
使用方法:
http函数是一个简单的curl封装函数,需要自己去实现,
http函数原型如下:
http($url,$post_data = null)
返回网页内容.
第一个参数$url,就是要访问的url地址,$post_data是post数据,如果为空,则代表GET访问.
1.使用加密后暗码登录 加密方法: sha1(sha1($pass))
$sina = new sina($username,$sha1pass)
2.直接使用原始暗码登录
$sina = new sina($username,$sha1pass,0)
执行之后如果$sina->status非空,则登录成功,否则登录失败.
登录成功之后,你就可以直接继续使用http函数来访问其它内容.
使用 unset($sina) 会自动注销登录.
