I am running a script which uploads a file to remote form
//submit form
$form_data = array("file_upload" => "#file.xml;type=text/xml","otherkey" => "overvalue");
$ch = curl_init();
$form_url = 'http://www.domain.com/form.php';
curl_setopt($ch, CURLOPT_URL, $form_url);
curl_setopt($ch, CURLOPT_POST, 1 );
curl_setopt($ch, CURLOPT_POSTFIELDS, $form_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
$postResult = curl_exec($ch);
echo $postResult;
The file is being uploaded perfectly, however on the remote server, after file upload and processing the page is reloaded (form.php), however the CURL post simply begins again.
I am guessing this is due to the POST data still being present? how can I do this so that the file is uploaded once, processed and then completed? I have set FOLLOWLOCATION = 0 but with no luck
Many thanks,
How do you know it begins again? If you infer it from your echo, it is echoed twice as you write this:
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0); //echoes result at init
instead of this
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //returns only result, not echoing

I am submitting login form data using curl in php, and from what I've observed the login POST has no response - the lander page is loaded by a subsequent GET request. What I'd like to know is how I can make a POST using curl and then a GET? For reference, here's my current code:
$ch = curl_init('https://<my url>');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Accept: text/html',
));
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_POST, 2);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'my post fields');
$result = curl_exec($ch);
// I need to make a get request to get the loggedin page here!?
curl_setopt($ch, CURLOPT_URL, 'https:<another_url>');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 0);
$result = curl_exec($ch);
echo curl_errno($ch);
I'm currently getting an error 52 from my POST which is no response, which I think should be expected. The issue is, when I tried to make a GET, I also got errno 52. Also for a sanity check, I retrieved my post fields my grabbing the form data from the network data from chrome dev tools.
Thanks in advance for the help!
I am trying to reproduce this POST https://www.screencast.com/t/OUE1StfLfyP7 in php but I couldn't archive that it works correctly because after downloading the image is not possible to open it
$url = "https://internal-api-staging-lb.interact.io/v2/contacts/X/documents/fr_FR9.gif";
$data = array('file' => '#'.realpath('https://www.viventura.de/images/icons/flags/fr_FR.gif'));
// Initialize cURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1 );
curl_setopt($ch, CURLOPT_HTTPHEADER, Array("Content-Type: application/octet-stream", "authToken: XX"));
// Set URL on which you want to post the Form and/or data
curl_setopt($ch, CURLOPT_URL, $url);
// Data+Files to be posted
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
// Pass TRUE or 1 if you want to wait for and catch the response against the request made
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// For Debug mode; shows up any error encountered during the operation
curl_setopt($ch, CURLOPT_VERBOSE, 1);
// Execute the request
$response = curl_exec($ch);
I am doing something wrong someone can give me a hand? Thanks a lot.
I am trying to login to a site using curl but for some reason when I use the print_r($login) to view the output, I always end up seeing the original login page without it being processed (it was supposed to return something like login success or fail), I think curl is not able to submit the form, any suggestion?
$user="something"; $pass="something";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, "username={$user}&password={$pass}");
curl_setopt($ch, CURLOPT_USERAGENT, "Something");
$login = curl_exec($ch);
print_r($login);
You need to add
curl_setopt($ch, CURLOPT_POST, TRUE);
To send POST content. Without it, your CURLOPT_POSTFIELDS will be ignored.
I try to login with curl to a SSL secured website but somehow I don't get it right.
The first curl connection retrieves the login form. An SSL issue in the beginning is resolved now. The fields used for authentication and all hidden fields are identified and used for the following POST. The cookie file is defined and the jar to read from as well. The cookie file is accessible and gets updated with each login attempt. A session cookie is successfully set by curl. The HTTPHEADER is removed to stop the request from hitting the 100 Continue wall. Curl is configured to follow up and to send a referer.
However, I still cannot find where the script gets stuck. Neither Curl nor PHP issue any error messages or warnings.
Here is the shortened script:
$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:')); // remove Expect header to avoid 100 Continue situations
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla [abbreviated]');
curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__).'/cacert.pem');
curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__).'/cookie.hq.txt'); // write cookies
curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__).'/cookie.hq.txt'); // read cookies
curl_setopt($ch, CURLOPT_COOKIESESSION, 1);
curl_setopt($ch, CURLOPT_URL, 'https://the_url.jsp');
$data = curl_exec($ch);
$error= curl_error($ch);
if(!empty($error))
echo '<p>'.$error.'</p>';
else
echo '<p>ok</p>';
Now the script reads the form, fills in the credentials and POSTs it back using the same curl_init handle:
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $options);
$data = curl_exec($ch);
$error=curl_error($ch);
But all I get back is the same form again and the same session cookie or a new one depending on the CURLOPT_COOKIESESSION setting.
When I log in manually I notice that there are two more cookies set: LtpaToken and LtpaToken2 but I never see them appearing in the request headers printed by the script.
Manually submitting the form works even without Javascript aktivated. So there cannot be some JS magic modifying the form data under the hood before submitting it.
Obviously I am missing something here. Any ideas where I can look further?
Solved: Finally the issue was due to an encoding issue in the POST.
Initially the POST data was created from an array with http_build_query().
Now the POST data is simply concatenated and both keys and values are urlencoded separately:
$options.=urlencode($fieldName).'='.urlencode($element->getAttribute('value'));

See below url:--
cURL login session
and try this:-
http://php.net/manual/en/function.curl-setopt.php
<?php
echo curl_grab_page("https://www.example.net/login.php", "https://www.example.net/", "username=foo&password=bar", "true", "null", "false");
// $url = page to POST data
// $ref_url = tell the server which page you came from (spoofing)
// $login = true will make a clean cookie-file.
// $proxy = proxy data
// $proxystatus = do you use a proxy ? true/false
function
curl_grab_page($url,$ref_url,$data,$login,$proxy,$proxystatus){
if($login == 'true') {
$fp = fopen("cookie.txt", "w");
fclose($fp);
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_TIMEOUT, 40);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
if ($proxystatus == 'true') {
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
}
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $ref_url);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
ob_start();
return curl_exec ($ch); // execute the curl command
ob_end_clean();
curl_close ($ch);
unset($ch);

I have another question concerning YouTube upload. Based on the answer that I received from khael here (replace form input file with direct file upload), the script uploads the video perfectly. However, the curl response is "Moved Temporarily". What I need instead is to get the YouTube video ID back.
Another problem is that the "nexturl" never gets called. If it was called, I could easily read the video id with "$_GET['id']" and write it to the database.
Here the code I'm working with
$ch = curl_init($response->url."?nexturl=".urlencode($nexturl));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]);
curl_setopt($ch, CURLOPT_POST, true);
$post = array(
"file"=>"#/path/to/file.avi",
"token"=>$response->token
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($ch);
Thanks,
Florian
Without testing I'd guess that if you add the FOLLOWLOCATION option you'd get what you're after:
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
