Question: Why is it giving this error and how do I resolve it?
I am using the Facebook Graph API to post a reply/comment to specific posts that I have already created in specific Facebook groups. I am a currently a member of the group and can reply/comment manually to my post.
The app is not currently "live" in the developer interface.
39 of the 80 some odd posts give this error:
Array ( [error] => Array ( [message] => (#200) Permissions error [type] => OAuthException [code] => 200 ) )
Access Token Code
//Gets Facebook Token ID for use in facebook-poster.php
session_start();
$app_id = "...";
$app_secret = "....";
$my_url = "......"; // redirect url
$code = $_REQUEST["code"];
if(empty($code)) {
// Redirect to Login Dialog
$_SESSION['state'] = md5(uniqid(rand(), TRUE)); // CSRF protection
$dialog_url = "http://ift.tt/1ep6vXc"
. $app_id . "&redirect_uri=" . urlencode($my_url) . "&state="
. $_SESSION['state'] . "&scope=publish_stream,publish_actions,read_friendlists,email";
echo("<script> top.location.href='" . $dialog_url . "'</script>");
}
if($_SESSION['state'] && ($_SESSION['state'] === $_REQUEST['state'])) {
$token_url = "http://ift.tt/JH6Whd?"
. "client_id=" . $app_id . "&redirect_uri=" . urlencode($my_url)
. "&client_secret=" . $app_secret . "&code=" . $code;
$response = file_get_contents($token_url);
$params = null;
parse_str($response, $params);
$longtoken=$params['access_token'];
}
echo $longtoken;
?>
