Question

使用,希望简单地获得用户数据:

$facebook = new Facebook(array(  
     appId   =>  xxx ,  
     secret  =>  yyy ,  
     cookie  => true  
)); 
$user = $facebook->getUser();
  if ($user) { // Checks if there is already a logged in user
  try {
    // Proceed knowing you have a logged in user who s already authenticated.
    $user_profile = $facebook->api( /me );
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
   }
}
else { 
   //Ask for bare minimum login
   $login_url = $facebook->getLoginUrl();
   header("Location: ".$login_url); 
}

My problem is that the $user is FB logged in, but $facebook->api( /me ) not only fails, but I don t get the App authorization dialog either. What am I doing wrong?

Answer 1

最终发现我的错误,以便记录在案:

$facebook = new Facebook(array(  
     appId   =>  xxxx ,  
     secret  =>  yyyyy ,  
     cookie  => true  
 )); 
$user = $facebook->getUser();
  if ($user) { // Checks if there is already a logged in user
  try {
    // Proceed knowing you have a logged in user who s authenticated.
    $user_profile = $facebook->api( /me );
  } catch (FacebookApiException $e) {
    // Will throw the very first time as the token is not valid
    error_log($e);
    $user = null;
   }
}
// $user is null : $user is either not logged in or the token is not valid
if(!$user) { //Ask for bare minimum login
    $login_url = $facebook->getLoginUrl();
   header("Location: ".$login_url); 
}
