facebook Uncaught OAuthException:必须使用活动访问令牌来查询有关当前用户的信息

Question

我一直在努力找出这个发生了什么.我的脚本工作正常,突然一半停止了.

我正在访问api并且正在获取访问令牌.使用访问令牌,我可以很好地访问用户的公共信息.但是,当我尝试将信息发布到他们的FB帐户时,我收到此错误.

Fatal error: Uncaught OAuthException: An active access token must be used to query information about the current user. 

知道这里发生了什么吗？我也在我的网站上使用会话来跟踪内部用户ID.不确定我的会话是否可能导致问题.

这是我上传的脚本,我收到了一个错误.

require 'facebook/src/facebook.php';


// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
  'appId'  => '12345678',
  'secret' => 'REMOVED',
  'fileUpload' => true, 
  'cookie' => true,
));
$facebook->setFileUploadSupport(true); 

$me = null;
// Session based API call.
if ($session) {
  try {
    $uid = $facebook->getUser();
    $me = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
  }
}


// login or logout url will be needed depending on current user state.
if ($me) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
  $loginUrl = $facebook->getLoginUrl();
}


$photo_details = array('message' => 'my place');
$file='photos/my.jpg'; //Example image file
$photo_details['image'] = '@' . realpath($file);
$upload_photo = $facebook->api('/me/photos', 'post', $photo_details);

Answer 1

使用:

$facebook->api('/'.$facebook_uid)

代替

$facebook->api('/me')

有用.

Answer 2

只需检查当前的Facebook用户ID $user,如果它返回null,则需要重新授权用户(或使用自定义$_SESSION用户ID值 - 不推荐)

require 'facebook/src/facebook.php';


// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
  'appId'  => 'APP_ID',
  'secret' => 'APP_SECRET',
));

$user = $facebook->getUser();

$photo_details = array('message' => 'my place');
$file='photos/my.jpg'; //Example image file
$photo_details['image'] = '@' . realpath($file);

if ($user) {
  try {
    // We have a valid FB session, so we can use 'me'
    $upload_photo = $facebook->api('/me/photos', 'post', $photo_details);
  } catch (FacebookApiException $e) {
    error_log($e);
  }
}


// login or logout url will be needed depending on current user state.
if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
// redirect to Facebook login to get a fresh user access_token
  $loginUrl = $facebook->getLoginUrl();
  header('Location: ' . $loginUrl);
}

我写了一个关于如何将图片上传到用户墙上的教程.

所以我有同样的问题,但这是因为我保存了访问令牌但没有使用它.可能是因为我因为截止日期而非常困,或者我只是没想到它!但万一其他人处于同样的情况:

当我登录用户时,我保存了访问令牌:

$facebook = new Facebook(array(
    'appId' => <insert the app id you get from facebook here>,
    'secret' => <insert the app secret you get from facebook here>
));

$accessToken = $facebook->getAccessToken();
//save the access token for later

现在当我向facebook发出请求时,我只是做了这样的事情:

$facebook = new Facebook(array(
    'appId' => <insert the app id you get from facebook here>,
    'secret' => <insert the app secret you get from facebook here>
));

$facebook->setAccessToken($accessToken);
$facebook->api(... insert own code here ...)
