php-custom隐私设置与Facebook SDK Feed帖子无法正常工作

Question

I am trying to post a simple message on my wall by using the Facebook PHP SDK but I get some troubles when I try to set up custom privacy rules, here is my code:

try {

                    $response = (new FacebookRequest(
                      $session, 'POST', '/me/feed', array(
                        'message' => @$_GET['message'],
                        'privacy' => json_encode(array(
                                        'friends' => 'SOME_FRIENDS',
                                        'value' => 'CUSTOM',
                                        'allow' => implode(',', $friends)
                                    ))
                      )
                    ))->execute()->getGraphObject();

                    echo "Posted with id: " . $response->getProperty('id');

                  } catch(FacebookRequestException $e) {

                    echo "Exception occured, code: " . $e->getCode();
                    echo " with message: " . $e->getMessage();

                  }

And i get the fallowing error: Exception occured, code: 100 with message: (#100) 'friends' value was not recognized

Someone could help me ?

EDIT The problem is that i do not have the real ID of the the friends, but i do not know how to get it when they do not use my application, any idea ?

Answer 1

If you see the Publish documentation for Feed, the privacy settings you are using are invalid. As you can no longer get IDs of friends (unless they use the application), so you cannot restrict posts to a select number of friends who's IDs you do not know.
