通过cURL远程登录hootsuite

Question

我正在尝试使用cURL远程登录Hootsuite。我希望Hootsuite应用程序在我自己的应用程序中显示在iframe中。我使用以下代码，但它似乎不起作用。我刚刚看到登录页面，但没有错误：登录。

$username="xxx"; 
$password="yyy"; 
$url="https://hootsuite.com/login"; 
$cookie="cookie.txt"; 

$postdata = "loginInfo[email]=".$username."&loginInfo[password]=".$password; 

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;    rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
curl_setopt ($ch, CURLOPT_REFERER, $url); 

curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); 
curl_setopt ($ch, CURLOPT_POST, 1); 
$result = curl_exec ($ch); 

echo $result;  
curl_close($ch);
