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

include('Snoopy.class.php');



 function login(){

	$snoopy = new Snoopy(); 

	$submit = "http://mp.weixin.qq.com/cgi-bin/login?lang=zh_CN";

	$post["username"] = '我的账号';

	$post["pwd"] = substr(md5('我的密码'), 0,16);

	echo $post["pwd"];

	$post["f"] = "json";

	$snoopy->submit($submit,$post);

	$cookie = '';

	print_r($snoopy->headers);exit;

	

 }

 login();

?>

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

var createLoginForm = function(e) {

var t = jQuery, n = function() {

var e = !1;

inputs = m.getVal();

switch (!1) {

case !!inputs.account:

s.trigger("Warning", [ f, "你还没有输入帐号！" ]);

break;

case !!inputs.password:

s.trigger("Warning", [ l, "你还没有输入密码！" ]);

break;

case !!inputs.verify || !!c.data("isHide"):

s.trigger("Warning", [ h, "你还没有输入验证码！" ]), r();

break;

default:

e = !0;

}

return e;

}, r = function() {

h.val(""), p.attr("src", "/cgi-bin/verifycode?username=" + m.getVal().account + "&r=" + +(new Date));

}, i = e.selector, s = t(i.error), o = t(i.errorArea), u = t(i.rememberAcct), a = t(i.changeImgLink), f = t(i.account).keydown(function(e) {

e.keyCode == 13 && l.focus().select();

}), l = t(i.password).keydown(function(e) {

e.keyCode == 13 && d.click();

}), c = t(i.verifyArea).data("isHide", 1).hide(), h = t(i.verify).keydown(function(e) {

e.keyCode == 13 && (l.val() ? d.click() : l.focus().select());

}), p = t(i.verifyImg).click(r), d = t(i.loginBtn), v = function(e, t) {

return;

var n, r, i;

};

s.bind("Warning", function(e, t, n) {

o.removeClass("dn"), s.text(n).hide().fadeIn();

}), p.bind({

load: function() {

v([ f, l ]), c.show().data("isHide", 0), h.focus().select();

},

error: function() {}

}), s.bind("Response", function(e, t, n) {

o.removeClass("dn"), s.html(n).hide().fadeIn(), v([ f, l ], "N"), c.data("isHide") || r();

switch (t) {

case "-3":

l.focus().select();

break;

case "-6":

h.focus().select();

break;

default:

f.focus().select();

}

t != "-32" && l.val("");

});

var m = {

showVerifyImg: r,

submit: function() {

if (!n()) return;

var e = m.getVal();

t.post("/cgi-bin/login?lang=zh_CN", {

username: e.account,

pwd: t.md5(e.password.substr(0, 16)),

imgcode: c.data("isHide") ? "" : e.verify,

f: "json"

}, function(t) {

var n = t.ErrCode + "", i;

u.hasClass("checkbox_checked") ? WXM.Helpers.setCookie("remember_acct", e.account, 30) : WXM.Helpers.setCookie("remember_acct", "EXPIRED", -1);

switch (n) {

case "-1":

i = "系统错误，请稍候再试。";

break;

case "-2":

i = "帐号或密码错误。";

break;

case "-3":

i = "您输入的帐号或者密码不正确，请重新输入。";

break;

case "-4":

i = "不存在该帐户。";

break;

case "-5":

i = "您目前处于访问受限状态。";

break;

case "-6":

i = "请输入图中的验证码", r();

return;

case "-7":

i = "此帐号已绑定私人微信号，不可用于公众平台登录。";

break;

case "-8":

i = "邮箱已存在。";

break;

case "-32":

i = "您输入的验证码不正确，请重新输入", r();

break;

case "-200":

i = "因频繁提交虚假资料，该帐号被拒绝登录。";

break;

case "-94":

i = "请使用邮箱登陆。";

break;

case "10":

i = "该公众会议号已经过期，无法再登录使用。";

break;

case "65201":

case "65202":

i = "成功登陆，正在跳转...", location.href = t.ErrMsg;

return;

case "0":

i = "成功登陆，正在跳转...", location.href = t.ErrMsg;

return;

case "-100":

i = '海外帐号请在公众平台海外版登录,点击登录';

break;

default:

i = "未知的返回。";

return;

}

s.trigger("Response", [ n, i ]);

}, "json");

},

getVal: function() {

return {

account: t.trim(f.val()),

password: t.trim(l.val()),

verify: t.trim(h.val())

};

},

setVal: function(e, n) {

return t(i).val(n).length;

}

};

return a.click(function() {

m.showVerifyImg();

}), d.click(m.submit), f.focus(), m;

};

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