微信公眾平台類比登陸有關問題

公眾平台類比登陸問題
為了獲得使用者的頭像和使用者名稱，查了下相關資料，只有類比登陸可以做到。
於是用snoopy類比登陸代碼如下

include('Snoopy.class.php');

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

 }
 login();
?>

獲得的頭部資訊中沒有set-cookie 登陸失敗，請問，我這段程式錯在哪裡了？還是說最近改了他的代碼了，我看公眾平台上的登陸js也是post過去這幾個內容

var createLoginForm = function(e) {
var t = jQuery, n = function() {
var e = !1;
inputs = m.getVal();
switch (!1) {
case !!inputs.account:
s.trigger("Warning", [ f, "你還沒有輸入帳號！" ]);
break;
case !!inputs.password:
s.trigger("Warning", [ l, "你還沒有輸入密碼！" ]);
break;
case !!inputs.verify || !!c.data("isHide"):
s.trigger("Warning", [ h, "你還沒有輸入驗證碼！" ]), 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 = "系統錯誤，請稍候再試。";
break;
case "-2":
i = "帳號或密碼錯誤。";
break;
case "-3":
i = "您輸入的帳號或者密碼不正確，請重新輸入。";
break;
case "-4":
i = "不存在該帳戶。";
break;
case "-5":
i = "您目前處於訪問保留狀態。";
break;
case "-6":
i = "請輸入圖中的驗證碼", r();
return;
case "-7":
i = "此帳號已綁定私人號，不可用於公眾平台登入。";
break;
case "-8":
i = "郵箱已存在。";
break;
case "-32":
i = "您輸入的驗證碼不正確，請重新輸入", r();
break;
case "-200":
i = "因頻繁提交虛假資料，該帳號被拒絕登入。";
break;
case "-94":
i = "請使用郵箱登陸。";
break;
case "10":
i = "該公眾會議號已經到期，無法再登入使用。";
break;
case "65201":
case "65202":
i = "成功登陸，正在跳轉...", location.href = t.ErrMsg;
return;
case "0":
i = "成功登陸，正在跳轉...", location.href = t.ErrMsg;
return;
case "-100":
i = '海外帳號請在公眾平台海外版登入,點擊登入';
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;
};

也是這四個值
username: e.account,
pwd: t.md5(e.password.substr(0, 16)),
imgcode: c.data("isHide") ? "" : e.verify,
