微信公众平台模拟登陆有关问题

微信公众平台模拟登陆问题
为了获得用户的头像和用户名，查了下相关资料，只有模拟登陆可以做到。
于是用snoopy模拟登陆代码如下

<br />
<?php <br />
<br />
include('Snoopy.class.php');<br />
<br />
 function login(){<br />
	$snoopy = new Snoopy(); <br />
	$submit = "http://mp.weixin.qq.com/cgi-bin/login?lang=zh_CN";<br />
	$post["username"] = '我的账号';<br />
	$post["pwd"] = substr(md5('我的密码'), 0,16);<br />
	echo $post["pwd"];<br />
	$post["f"] = "json";<br />
	$snoopy->submit($submit,$post);<br />
	$cookie = '';<br />
	print_r($snoopy->headers);exit;<br />
	<br />
 }<br />
 login();<br />
?><br />

获得的头部信息中没有set-cookie 登陆失败，请问，我这段程序错在哪里了？还是说最近微信改了他的代码了，我看微信公众平台上的登陆js也是post过去这几个内容

也是这四个值
username: e.account,
pwd: t.md5(e.password.substr(0, 16)),
imgcode: c.data("isHide") ? "" : e.verify,
