How to keep CURL session alive?

[beyzad]

Hi.

 

I need to read some contents from a CURL session. Then post data again with the same session. is there anyway to do that?

 

I mean somethings like Fake Yahoo! ID makers that shows the CAPTCHA to user, then submit form.

 

Thanks

I believe if you don't close the session; you can use it again...

SHould i use curl_init() again or not?

 

If i not, I'll receive an error. else, that's not work.

This won't work? I believe I've done this before...

<?php
//Create the curl session
$curl_handle=curl_init();

//Go to site 1
curl_setopt($curl_handle,CURLOPT_URL,'http://example.com');
curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2);
$site1 = curl_exec($curl_handle);

//Now go to site 2
curl_setopt($curl_handle,CURLOPT_URL,'http://www.asdf.com');
curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2);
$site2 = curl_exec($curl_handle);

//Now close
curl_close($curl_handle);

I assume you're logging into a website first and then trying to retrieve some information? You'll need to specify a COOKIEJAR so that any cookies created by the first request (i.e. the session id) can be stored and used in the second request.

 

And no, you don't make two calls to curl_init().

That's working, but with different sessions. i need to keep the first url session.

I fount this on php.net:

 

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookiefile");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookiefile");
curl_setopt($ch, CURLOPT_COOKIE, session_name() . '=' . session_id());
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($ch, CURLOPT_URL, 'http://site.com/page1.php');
$result1 = curl_exec($ch);

curl_setopt($ch, CURLOPT_URL, 'http://site.com/page2.php');
$result2 = curl_exec($ch);

curl_close($ch);
?>

 

But i still cant understand how to grab somethings from the first URL, then post them to the second url?

 

Please help me.

To get something from the first page to use in the second request, you'll need to extract the information from the first request. You have the source of the page stored in $result1, so you could use regular expressions to get the data you need (e.g. preg_match).

 

Without actually knowing what sort of information you're trying to retrieve, it's hard to give you any more specific help than that.

Exuse me..

 

I need to grab CAPTCHA image from the first URL and show that to the user, Then POST data to the second URL with same session.

 

Thanks for your help.

I'm not overly convinced on why you'd want to do this...but anyway.

 

You'll need to make the request to the first page, storing the cookie that is set and extracting the image name. Of course, if the image name is always the same, you don't actually need to bother, though you do still need to make the request to the first page to have the cookie set. Show the user the image. Then make the second request, providing the cookie data you saved from the first one.
