Help me to use PHP curl

[balasun]

Hello all,

 

I am using PHP curl function to login in secure server site by post the parameters.

 

My code is as follows:

 

$cookie_jar = tempnam('tmp/','cookie');

$url = "https://nameos site/login";
$POSTFIELDS = 'session_key=emailid&session_password=password&session_login=&session_rikey=invalid key';
$reffer = "http://www.securesitename.com";
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624 Netscape/7.1 (ax)";
$cookie_file_path = "tmp/"; 

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$POSTFIELDS);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_REFERER, $reffer);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
echo $result = curl_exec($ch);
exit;

curl_close($ch);

 

But the login does not done.  Pls help me to do login.. Is any special parameters need when we use CURL for secured site?

Add this little code and show us \echo $result\ output.

 

curl_setopt($ch, CURLOPT_HEADER, true);

 

You have at least 1 error, cookiefile and cookiejar need a filename not a directory use something like that, you make 2 variable for this and don't use the right one  :

 

$cookie_file_path = "tmp/cookie.txt";

 

And make a if to be sure your curl_exec work like that :

 

$output = curl_exec($ch);
$info = curl_getinfo($ch);

if ($output === false || $info['http_code'] != 200) {
  echo "No cURL data returned for $url [". $info['http_code']. "]";
  if (curl_error($ch)) echo curl_error($ch);
  }
else {
  echo $output;
}

You shouldn't post your password here

 

LinkedIN seem to have a API you should use that instead :

http://www.linkedin.com/static?key=developers_apis

 

And the HTTP code 200 mean it work. You can remove the curl_setopt($ch, CURLOPT_HEADER, true); And try again. But it seem to use AJAX so you may need to read the javascript on linkedin and figure all the request it made to the server and try to emulate it. Lot of job and probably a bad idea since you can use the api to do the same.
