Using PHP CURL to login to a remote web site

Question

I'm trying to login to a remote web site using CURL, but can't seem to get it to work.

The page I'm trying to login to is: https://vp1-voiceportal.megapath.com/Login/

So far, I've tried the following:

$username="username"; 
$password="password"; 
$url="https://vp1-voiceportal.megapath.com/Login/servlet/com.broadsoft.clients.oam.servlets.Login"; 
$cookie="cookie.txt"; 

$postdata = "EnteredUserID=".$username."&password=".$password."&domain=&UserID=&rememberPass="; 

$ch = curl_init(); 
curl_setopt ($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);

Answer 1

EDIT: The URL you specified is wrong, it should be:

https://vp1-voiceportal.megapath.com/servlet/com.broadsoft.clients.oam.servlets.Login

And not:

https://vp1-voiceportal.megapath.com/Login/servlet/com.broadsoft.clients.oam.servlets.Login

It looks like you need to follow redirects and specify the cookie file (for reading), try:

$ch = curl_init(); 
curl_setopt ($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 ($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie); 
curl_setopt ($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);

It's also a good practice so specify an absolute (and writable) path to the cookie file.
