I'm trying to grab cookies from a remote host with a little script which works well:
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_NOBODY, TRUE);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_COOKIE, TRUE);
// grab URL and pass it to the browser
$opt = curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
I would like to know how I can pass them back to the client?
I've searched high and low for the answer to this question but cant find anything...
We've got a single server and on it we've got a PHP service with an API.
We've recently written an PHP app which interacts with the API. When it goes live the API and the app will be on the same server.
However, when they are on the same server the cURL requests from the app to the API always return false. I'm sure this must be something to do with the way that the request is being routed by the server. Is there any way to make this work properly?
$url = 'http://api.some_address_on_the_same_server.com';
$postdata = array(...);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch); // $result is always false when on the same server for some reason
curl_close($ch);
Must be related to locking session situations. Try this way.
<?php
$url = 'http://api.some_address_on_the_same_server.com';
$postdata = array(...);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
session_write_close();
$result = curl_exec($ch); // $result is always false when on the same server for some reason
curl_close($ch);
session_start();
?>
EDIT :
Have you added an exception in your windows host file ?
/windows/system32/drivers/etc/hosts
like
127.0.0.1 yourdomain.com

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 developed a API for my website. API working 100% correctly. But I designed it to catch and execute functions from this kind of POST parameters$_POST['functionName']; $_POST['parameter']; Now, in request page i want to send those as $_POST, I managed to do deal with that. But my problem is, how can I create a function that can post my parameters for each functions in API using curl. Here is my code which send requests to my API.
$url = 'http://localhost/myapi/api.php';
$postfields['functionName'] = "myFunction";
$postfields['parameter'] = "1";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
$data = curl_exec($ch);
$results = json_decode($data, true);
curl_close($ch);
I need to check if remote file are online and they didn't change. The problem is that those files are big, so I want to read the http header only and then abort the request. The result would be based on response status code and content length field.
How can I do it in PHP?
You can use the get_headers() function.
If you prefer cURL, you can use CURLOPT_NOBODY:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_NOBODY, TRUE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$headers = curl_exec($ch);
