Using CURL and PHP to get facebook cookie when login

Question

I'm trying to get my_cookie.txt with the facebook cookie so I can re-use it with CURL for other facebook pages.

Here is my PHP code... When I try this... i see the facebook login page but it gives me an error saying my cookies in my browser must be enable... BUT they are enable.

$email = 'my email';
$password = 'mypassword';
$ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://login.facebook.com/login.php');
    curl_setopt($ch, CURLOPT_POSTFIELDS,'email='.urlencode($email).'&pass='.urlencode($password));
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_COOKIEJAR, "my_cookies.txt");
    curl_setopt($ch, CURLOPT_COOKIEFILE, "my_cookies.txt");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3");
$page =      curl_exec($ch);

echo $page;

Here is the error I see

enter image description here

Any idea what I'm doing wrong?

You should not try and scrape Facebook pages, it’s against their TOS. If you want to do something on Facebook, use their API. — CBroe, Jan 11 '15 at 21:02

First of all it is against the TOS of facebook (better use api).

The login is just not about to hitting the login page. You have to browse the home page first (using curl in this case) and store the cookie in jar. Then during the login use the cookie with your login request. You may need to find the token or something like that from the home page (if they use any).

So the steps are for any site you want to make a login request:

1) Browse home page using curl. Store cookies using jar. And don't forget to close the curl.

2) If the page has any token or hidden parameter then parse that from the html.

3) Initialize a new curl, prepare post parameter with user/pass + hidden parameters. Don't forget to add cookie jar.

try adding these lines:

curl_setopt( $ch, CURLOPT_COOKIESESSION, true );
curl_setopt( $ch, CURLOPT_COOKIEJAR, uniquefilename );
curl_setopt( $ch, CURLOPT_COOKIEFILE, uniquefilename );

I already had the last 2, I tried adding the first one and it gave me the same result – user3011784 Jan 11 '15 at 21:53
Then it could be possible that Facebook uses javascript cookies instead of server side cookies, if so it would be more difficult to implement. Try to debug and find from which side are you receiving cookies – manuelbcd Jan 11 '15 at 21:56

Hey have you tried to set the file permission of my_cookies.txt to 644 permission? Also, you will need all the three line above.

$cookie_file = "my_cookies.txt";
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);

you also need to make sure that you have aces to that cookie. chmod 777 my_cookies.txt – Cobuz Alexandru Jun 27 '16 at 05:28
