Question

问题：为什么会出现此错误，如何解决？

我正在使用Facebook Graph API向我已在特定Facebook群组中创建的特定帖子发布回复/评论。我目前是该群组的成员，可以手动回复/评论我的帖子。

该应用目前在开发人员界面中不是“实时”。

39一些奇怪的帖子中的{p> 80会出现此错误：

Array ( [error] => Array ( [message] => (#200) Permissions error [type] => OAuthException [code] => 200 ) )

访问令牌代码

//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 = "https://www.facebook.com/dialog/oauth?client_id=" 
       . $app_id . "&redirect_uri=" . urlencode($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 = "https://graph.facebook.com/oauth/access_token?"
       . "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;
