Question

我使用以下代码获取用户的Facebook详细信息。现在，当我运行它时，页面会显示“请登录”，其中login是锚标记。当我点击登录时，另一页显示“无效的应用程序ID：YOUR_APP_ID”。当我做这一切时，我已登录到Facebook。那么为什么我没有得到细节？

<?php
  include 'facebook-php-sdk/src/facebook.php';
  $config = array(
'appId' => 'YOUR_APP_ID',
'secret' => 'YOUR_APP_SECRET',
'allowSignedRequest' => false // optional but should be set to false for non-canvas 
apps
);

 $facebook = new Facebook($config);
  $user_id = $facebook->getUser();
?>
<html>
  <head></head>
  <body>
  <?php

    if($user_id) {
     // We have a user ID, so probably a logged in user.
      // If not, we'll get an exception, which we handle below.

     try {
      $user_profile = $facebook->api('/me','GET');
      echo "Name: " . $user_profile['name'];

    } catch(FacebookApiException $e) {

       // If the user is logged out, you can have a 
      // user ID even though the access token is invalid.
     // In this case, we'll get an exception, so we'll
    // just ask the user to login again here.

    $login_url = $facebook->getLoginUrl(); 
    echo 'Please <a href="' . $login_url . '">login.</a>';
    error_log($e->getType());
    error_log($e->getMessage());
  }   

} else {

  // No user, print a link for the user to login
  $login_url = $facebook->getLoginUrl();
  echo 'Please <a href="' . $login_url . '">login.</a>';
}
  ?>
 </body>
</html>

我认为您需要将YOUR_APP_ID和YOUR_APP_SECRET替换为您在创建应用后在Facebook开发者页面上找到的值。

Where can I find my Facebook application id and secret key?
