Question

im trying to test example from developers webpage

$token_url = "https://graph.facebook.com/oauth/access_token?" .
    "client_id=" . facebook::getConfig( 'appId' ) .
    "&client_secret=" . facebook::getConfig( 'secret' ) .
    "&grant_type=client_credentials";
 $app_access_token = file_get_contents($token_url);   
 $user_id = "100002758712176";
 $apprequest_url = "https://graph.facebook.com/".
    $user_id .
    "/apprequests?message='test string'&"  .   
    $app_access_token . "&method=post";
$result = file_get_contents(urlencode($apprequest_url));
echo "App Request sent? ". $result;

and got eror [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request
when i use $apprequest_url in browser all works . Where is the problem ?

Answer 1

First you should urlencode the string you are sending in url:

$apprequest_url = "https://graph.facebook.com/" . $user_id . "/apprequests?message=" . urlencode('test string') . "&" . $app_access_token . "&method=post";
