PHP curl 模拟登陆 获取cookie求助

菜鸟学习使用PHP curl模拟登陆，等陆weiphon论坛时用以下代码成功，登陆www.xiaomi.com就死活成功不了，求助啊。窃以为是cookie获取有问题。麻烦牛人帮忙解决一下。苦思无所得夜不能寐啊！

<?php	$cookie_file=tempnam('./temp','cookie');	$login_url='https://account.xiaomi.com/pass/serviceLoginAuth';	$post ='user&pwd=&sid=eshop&callback=http%3A%2F%2Forder.xiaomi.com%2Flogin%2Fcallback%3Ffollowup%3Dhttp%253A%252F%252Fwww.xiaomi.com%252F%26sign%3DMjk4NmVlYzNiOWY5YTkwMjExNzg5MjkyNzE3ZmIxOGM4YTBiMDk1Mg%2C%2C&_sign=f%2FKB8SAfmaLZ0s28kcLtBSmZlEM%3D&_json=true'//避免不必要的麻烦 post的具体帐号密码去掉了	$ch=$curl=curl_init($login_url);	curl_setopt($ch,CURLOPT_HEADER,0);	curl_setopt($ch,CURLOPT_RETURNTRANSFER,0);	curl_setopt($ch,CURLOPT_POST,1);	curl_setopt($ch,CURLOPT_COOKIEJAR,$cookie_file);	curl_setopt($ch,CURLOPT_POSTFIELDS,$post);	curl_exec($ch);	curl_close($ch);	$url="http://www.xiaomi.com/index.php";	$ch=curl_init($url);	curl_setopt($ch,CURLOPT_HEADER,0);	curl_setopt($ch,CURLOPT_RETURNTRANSFER,0);	curl_setopt($ch,CURLOPT_COOKIEFILE,$cookie_file);	$contents=curl_exec($ch);	curl_close($ch);		?>

回复讨论(解决方案)

把第十九行删除了

<?php    $url="http://www.xiaomi.com/index.php";    $ch=curl_init($url);    curl_setopt($ch,CURLOPT_HEADER,0);    curl_setopt($ch,CURLOPT_RETURNTRANSFER,0);    //curl_setopt($ch,CURLOPT_COOKIEFILE,$cookie_file);    echo $contents=curl_exec($ch);    curl_close($ch);

测试成功

可是这样就没达到模拟帐号登陆的效果呀。只是采集了xiaomi的主页。

那说明还有数据没有提交。例如：
curl_setopt($ch, CURLOPT_REFERER,
post的数据不全：
两周内自动登录的input标志：auto=1
网页里面表单的其它值等。

$login_url='https://account.xiaomi.com/pass/serviceLoginAuth';
应为：
$login_url='https://account.xiaomi.com/pass/serviceLoginAuth2';

<form method="post" action="/pass/serviceLoginAuth2" id="loginForm" onsubmit="return validate_form()">	<input type="hidden" name="passToken" id="passToken" value="" />        <div class="input-field clearfix" id="loginId">          <input type="text" id="user_ph" class="input_kuang item errortip" value="邮箱/手机号码/小米ID" style="color:#999;display:none;"/>          <input type="text" name="user" value="" id="user" class="input_kuang item errortip" placeholder="邮箱/手机号码/小米ID" isRequired="true" rule="(^[\w.\-]+@(?:[a-z0-9]+(?:-[a-z0-9]+)*\.)+[a-z]{2,6}$)|(^1[3|4|5|8]\d{9}$)|(^\d{3,}$)|(^\++\d{2,}$)" autocomplete="off"/>          <span class="littlepop"><!-- 错误提示小气泡 -->            <span class="popmessage error_tip">              <span class="error_icontwo"></span><span id="errorTip">帐户名错误</span>            </span>            <span class="popmessage empty_tip">              <span class="error_icontwo"></span><span>请输入帐户名</span>            </span>            <i class="little_corner"></i>          </span>        </div>        <div class="input-field clearfix" id="loginPass">          <input type="text" id="pwd_ph" value="密码" class="input_kuang item errortip" style="color:#999;display:none;"/>          <input type="password" name="pwd" class="input_kuang item errortip" id="pwd" placeholder="密码" isRequired="true" autocomplete="off"/><!-- error_put为出现错误时的黄框 -->          <span class="littlepop">            <span class="popmessage empty_tip">              <span class="error_icontwo"></span><span>请输入密码</span>            </span>             <i class="little_corner"></i>          </span>          <input type="hidden" name="callback" value="https://account.xiaomi.com">          <input type="hidden" name="sid" value="passport">          <input type="hidden" id="qs" name="qs" value="%3Fsid%3Dpassport"/>          <input type="hidden" name="hidden" value="">          <input type="hidden" name="_sign" value="KKkRvCpZoDC+gLdeyOsdMhwV0Xg=">        </div>                <div class="cooke">          <label for="auto"><input type="checkbox" id="auto" name="auto" value="true" class="Mradio val_mT" /><span class="val_m">两周内自动登录</span></label>        </div>        <div class="sub_log clearfix">          <div class="sub_login flt_l"><input type="submit" class="no_bg" value="登录"/></div>          <a href="/pass/forgetPassword">忘记密码?</a>        </div>      </form>

里面所有 的值，其中passToken可能是使用js生成的。

感谢大神提供思路，我再试试看~
