使用Facebook PHP SDK发布到用户的Facebook Wall

Question

I'm integrating my web-based game to a Facebook Game . Facebook login, getting user id, getting user profile picture is OK . But i need to post somethings to wall (For example, John Doe earned 50 point!) .

I have offline_access and publish_Stream permissions for my Facebook App.

Now i want to publish some links automatically. I'm using Facebook PHP SDK with Yii.

I can get Facebook User ID etc... But i don't know how can i post somethings to user's wall, automatically (for example when user is offline).

I'm looking Graph API Post document's Publishing title. But i need access_token parameter for use this. And i'm not sure where is this access_token .

Answer 1

PHP-SDK 3.1.1

To generate app and user tokens. $app_access_token & $access_token

*The user access_token if you have offline access will never expire, unless user deAuthorizes your app. You would need to use for posting to a users wall when they are offline or not interacting with your application.*

<?php
require './src/facebook.php';
$facebook = new Facebook(array(
  'appId'  => '135669679827333',
  'secret' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
));
 $user = $facebook->getUser();
 if ($user) {
   try {
     // Proceed knowing you have a logged in user who's authenticated.
     $user_profile = $facebook->api('/me');
   } catch (FacebookApiException $e) {
     error_log($e);
     $user = null;
   }
 }
 if ($user) {
   $logoutUrl = $facebook->getLogoutUrl();
 } else {
   $loginUrl = $facebook->getLoginUrl();
 }
// Create Application Access Token
$app_access = "https://graph.facebook.com/oauth/access_token?client_id=135669679827333&client_secret=xxxxxxxxxxxxxxxxxxxxxxxx&grant_type=client_credentials";
$app_access_token = file_get_contents($app_access);
// If we have a user who is logged in, create access_token with session.
if ($user) {
$access_token = $_SESSION['fb_135669679827333_access_token'];
}
?>
