Facebook-PHP-SDK：api（'/ me'）無法正常工作，很奇怪

Question

這是我的代碼：

    $session = $facebook->getSession();
var_dump($session);/*it says session is perfectly established*/
try {
    $uid = $facebook->getUser();
    echo '<br>';
    var_dump($uid);/*User id is found*/
    $fb_user = $me = $facebook->api('/me');/*PHP execution doesn't go forward, here it breaks*/
    echo '<br>';
    var_dump($fb_user);/*PHP execution doesn't come up to here*/

編輯：我在catch部分有print_r $ exception並得到以下長消息：

FacebookApiException Object

我正在使用SDK版本2.1.2。 我對使用SDK 3或更高版本有一些限制。

Answer 1

我的猜測是，正在引發異常，並且您沒有看到此異常，因為您的PHP錯誤報告設置未正確調整。

將此添加到您的PHP文件的頂部：

ini_set('display_errors', 1);
error_reporting(E_ALL);

然后，您應該在訪問頁面時看到PHP錯誤。
