Estou desesperadamente a tentar colocar um script em PHP que faça LIKE a uma foto de uma página do Facebook.. usando a OPEN GRAPH e SDK PHP do Facebook.
tenho este código para já:
Código:
<?php
//include "dbc.php";
require './src/facebook.php';
$url = (!empty($_SERVER['HTTPS'])) ? 'https://'.$_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF'].$_SERVER['REQUEST_URL'] : 'http://'.$_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF'].$_SERVER['REQUEST_URL'];
$facebook = new Facebook(array(
'appId' => '******',
'secret' => '******',
'cookie' => true, // enable optional cookie support
));
$user = $facebook->getUser();
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
//$pageInfo = $facebook->api('/'.$pageid.'?access_token='.$_SESSION['fb_112104298812138_access_token].');
//$pageInfoUser = $user_profile[id];
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
/* */
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$params = array(
scope => 'read_stream,publish_stream,publish_actions,offline_access',
redirect_uri => $url
);
$loginUrl = $facebook->getLoginUrl($params);
}
$access_token = $facebook->getAccessToken();
// $access_token = $_SESSION['user_id'];
//$_SESSION['fb_135669679827333_access_token'];
if(!$user){
echo ' : <a href="'.$loginUrl.'" target="_self">Login</a> ';
}else{
echo '<a href="'.$logoutUrl.'?'.$app_access_token.'" target="_blank">Logout</a>';
}
?>
<?
function GetCH(){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://graph.facebook.com/oauth/access_token?client_id=112115512230132&client_secret=ef3d2a30aa9a3f799130565b8391d42dT&grant_type=client_credentials");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT_MS,20000);
if(substr($url,0,8)=='https://'){
// The following ensures SSL always works. A little detail:
// SSL does two things at once:
// 1. it encrypts communication
// 2. it ensures the target party is who it claims to be.
// In short, if the following code is allowed, CURL won't check if the
// certificate is known and valid, however, it still encrypts communication.
curl_setopt($ch,CURLOPT_HTTPAUTH,CURLAUTH_ANY);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
}
$sendCH = curl_exec($ch);
curl_close($ch);
return $sendCH;
};
echo "Access_token : ".$access_token;
$app_access_token = GetCH();
if($_GET['postid']){
$postid = $_GET['postid'];
echo "test1";
}else{
$postid = "ERROR";//'135669679827333_151602784936066';
}
if($access_token){
echo "test2";
$pageLike = $facebook->api('/'.$postid.'/likes?access_token='.$access_token.'&method=post', 'POST');
}
?>

Tenho 2 erros:
o user_id dá-me sempre 0
e este erro: Uncaught OAuthException: Invalid OAuth access token signature.
Tenho andado em fóruns internacionais e nacionais e ninguém me resolve isto..
Se alguém me poder ajudar agradeço.
