I am trying to get CI session from an external file. I have a page on CI that dumps the current session. When i access direct it operates as expected. However when i access via CURL it returns nothing. I believe CI session is lost when sending request using CURL.
My question is how do i send this session data together with my curl request.
The code i am using is as below.
$url = "http://localhost/cdmcl/dashboard/getsession";
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
echo $data;
You need to set CURLOPT_COOKIEFILE so that cURL saves its cookies into a file.
So, for Code Igniter you have to write like this:
$this->curl->option(CURLOPT_COOKIEFILE,'cookies_1.txt');

I am working on an online shop payment system and have to deal with both JSP and PHP file. Here is the partial flow of the transaction:
PHP gets the encrypted string from $_REQUEST & passes it to JSP by cURL.
JSP decrypts it by calling corresponding API function.
JSP passes the decrypted variables back to PHP.
PHP receives the variables and updates the database.
PHP display response message.
Here is the PHP code:
<?php
$data = $_REQUEST['String'];
$url = "http://demo:8000/decrypt.jsp";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "String=$data");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec ($ch);
curl_close ($ch);
//print $result;
//update database...
?>
I have done some testing and the encrypted string can be successfully passed to JSP by cURL. However, I have no idea how to pass the JSP variables back to the same PHP file.
Is there any solution for this problem?
I am using curl request to hit the has-offers conversion url from my sevrver with the help of curl but it is not working.But when I call the same URL using a browser, it works.Is they can block CURL requests?.I am not getting why, is there any port blocking issue.
Below is php code to call url using curl request.
<?php
function curl_get_contents($url)
{
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$url="http://paravey.go2cloud.org/aff_l?offer_id=12&aff_id=1000";
$contents = curl_get_contents($url);
echo $contents;
?>
Please help me thanks in Advance
The url you are curling is a pixel tracking url:
http://paravey.go2cloud.org/aff_l?offer_id=12&aff_id=1000
The aff_l endpoint looks for a cookie with session information (hence why it works in the browser).
If you want to create conversions with server side code, you will need to store the session identifier (the transaction_id) in your system and use the aff_lsr endpoint to send that data to HasOffers to trigger a conversion.
The url for this would look like this:
http://paravey.go2cloud.org/aff_lsr?transaction_id= VALUE
Where Value is the session identifier you have stored.
I would ask the HasOffers support team if you have more issues with this.
I am using CURl to retrieve a page for a small search engine project I am working on, but on some pages it's not retrieving the entire page.
The function that I have setup is:
public function grabSourceCode($url) {
// Try and get source code using #file_get_contents
$ch = curl_init();
$timeout = 50;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_USERAGENT,'NameBot/0.2');
$source_code = curl_exec($ch);
curl_close($ch);
return $source_code;
}
and I am retrieving the page using:
$Crawler->grabSourceCode('https://sedo.com/search/searchresult.php4?keyword=cats&language_output=e&language=e')
on this page I get everything, but on this page, I only get part of the page.
I have tried using file_get_contents() but that has the same results.
It seem's to be an issue with dynamic loading of the page, when I run the browser in JavaScript blocking mode it shows the same results as the CURl function.
Is there anyway to do this in PHP, or would I have to look at another language, such as JavaScript?
Thanks, Daniel
I have a cURL script that is sending login info to a script.
//open connection
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url;
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields1);
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);
//open connection
The script has a setcookie function.
setcookie("cookie_email",$email,time()+(3600*24*$i),"/");
setcookie("cookie_password",$password,time()+(3600*24*$i),"/");
When I login to the form using the form everything works as expected. For some reason when you run the cURL it's skipping the setcookies function.
I've been all over the net and I can't find a solution. I'm not sure why it's failing to set the cookies.
Any step in the right direction would be much appreciated.
Thanks,
Phil
UPDATE! - Getting Closer
Okay I have made some changes that grab cookies and put them into a cookie file. Two Issues I set.
1. The cookied password in the file reads: deleted
2. The cookies aren't being set in the browser.
How do I get the md5($password) into the file and how does:
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies/cookies.txt');
set the cookies in the browser?
You must set the CURL_COOKIEJAR and CURL_COOKIEFILE options for curl to set where cookies should be stored and loaded from respectively.
EDIT: Your example rewritten:
//open connection
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url;
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields1);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies/cookies.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies/cookies.txt');
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);
This assumes you have created a directory 'cookies/' and will save the cookies in a file called 'cookies.txt' (as long as your webserver can write to that directory, it will create the file itself)
Subsequent requests will then use any cookies stored in cookies.txt when sending their request (assuming you set the cookiefile for that request as well)
Im using cURL to post data to a php file (setcookie.php) on another domain.
The file, setcookie.php is supposed to set a cookie on that domain with the data posted to it.
The problem is the cookie doesn't want to be set when im doing it with cURL, because cURL returns to the calling file/domain, i guess.
So how can I make cURL not come back to the calling file?
Or is there an easier way to do this?
Here's my code :
$ch = curl_init ("http://<other domain>/setnewcookie.php");
curl_setopt ($ch, CURLOPT_POST, true);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $datatopost);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, false);
$returndata = curl_exec ($ch);
Here's what you need to do:
$ch = curl_init('http://example.org/setnewcookie.php');
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_exec($ch);
For cookies to work with cURL, you need to define both CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE. ALso, if you don't want the content of "http://example.org/setnewcookie.php" to be outputted to the browser, you need to set CURLOPT_RETURNTRANSFER to TRUE.
This will create a cookie on your server that cURL can use for subsequent requests but it won't allow the user of your website for instance to use that cookie. If the intent is for the user to be logged in on both sites, this will not work as-is.
For cross sub-domains (as in between www1.example.org and www2.example.org), have a look at PHP authentication with multiple domains and subdomains.
If you want the cookie to get sent from domain2 to browser, browser needs to make request directly.
So if you must get the information from domain1 and user must not get it directly, I'd somehow encrypt the data and redirect browser to send the request to domain2 like this:
domain1/script.php
$return_url = 'http://domain1/script2.php';
$request_url = 'http://domain2/setnewcookie.php';
$request = $request_url . '?data=' . url_encode($encrypted_data) . '&return_url=' . urlencode($return_url);
header('Location: ' . $request);
exit;
And then in domain2/setnewcookie.php just decrypt the data, set the cookie and once that is done, redirect user back to domain1 with help of the $return_url.
Still not sure if this was what you were trying to accomplish, HTH.
