Question

这是我的完整代码。

// include required files form Facebook SDK

require_once( 'Facebook/HttpClients/FacebookHttpable.php' );
require_once( 'Facebook/HttpClients/FacebookCurl.php' );
require_once( 'Facebook/HttpClients/FacebookCurlHttpClient.php' );
require_once( 'Facebook/Entities/AccessToken.php' );
require_once( 'Facebook/Entities/SignedRequest.php' );
require_once( 'Facebook/FacebookSession.php' );
require_once( 'Facebook/FacebookRedirectLoginHelper.php' );
require_once( 'Facebook/FacebookRequest.php' );
require_once( 'Facebook/FacebookResponse.php' );
require_once( 'Facebook/FacebookSDKException.php' );
require_once( 'Facebook/FacebookRequestException.php' );
require_once( 'Facebook/FacebookOtherException.php' );
require_once( 'Facebook/FacebookAuthorizationException.php' );
require_once( 'Facebook/GraphObject.php' );
require_once( 'Facebook/GraphSessionInfo.php' );

use Facebook\HttpClients\FacebookHttpable;
use Facebook\HttpClients\FacebookCurl;
use Facebook\HttpClients\FacebookCurlHttpClient;
use Facebook\Entities\AccessToken;
use Facebook\Entities\SignedRequest;
use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookOtherException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;
use Facebook\GraphSessionInfo;

// start session
session_start();

// init app with app id and secret
FacebookSession::setDefaultApplication( 'KEY','SECRET' );

// login helper with redirect_uri
$helper = new FacebookRedirectLoginHelper( 'SITE_NAME.php' );

// see if a existing session exists
if ( isset( $_SESSION ) && isset( $_SESSION['fb_token'] ) ) {
  // create new session from saved access_token
  $session = new FacebookSession( $_SESSION['fb_token'] );

  // validate the access_token to make sure it's still valid
  try {
    if ( !$session->validate() ) {
      $session = null;
    }
  } catch ( Exception $e ) {
    // catch any exceptions
    $session = null;
  }
}  

if ( !isset( $session ) || $session === null ) {
  // no session exists

  try {
    $session = $helper->getSessionFromRedirect();
  } catch( FacebookRequestException $ex ) {
    // When Facebook returns an error
    // handle this better in production code
    print_r( $ex );
  } catch( Exception $ex ) {
    // When validation fails or other local issues
    // handle this better in production code
    print_r( $ex );
  }

}

// see if we have a session
if ( isset( $session ) ) {

  // save the session
  $_SESSION['fb_token'] = $session->getToken();
  // create a session using saved token or the new one we generated at login
  $session = new FacebookSession( $session->getToken() );

  // graph api request for user data
  $request = new FacebookRequest( $session, 'GET', '***/1458726944414455/likes***' );
  $response = $request->execute();
  // get response
  $graphObject = $response->getGraphObject()->asArray();

  // print profile data
  echo '<pre>' . print_r( $graphObject, 1 ) . '</pre>';

  // print logout url using session and redirect_uri (logout.php page should destroy the session)
  echo '<a href="' . $helper->getLogoutUrl( $session, 'SITE_NAME/logout.php' ) . '">Logout</a>';

} else {
  // show login url
  echo '<a href="' . $helper->getLoginUrl( array( 'email', 'user_friends' ) ) . '">Login</a>';
}

在上面的 * * 部分中，如果我放置一些Facebook页面名称或“我”，则代码可以正常工作。但是当我插入＆＃39; / 1458726944414455 / likes＆＃39;像这样的东西，我无法获得任何价值，所以结果总是这样 Array（）

令我生气的原因是，/ 1458726944414455 /喜欢这在https://developers.facebook.com/tools/explorer，这是Graph API资源管理器中工作正常。我认为在API API浏览器和我自己的网站中，令牌范围没有那么不同。

有什么问题？我搜索了每个关于facebook php sdk或graph api的网站，但他们使用的代码几乎和我一样。

这是因为我没有对评论提交表格做任何事情吗？我只是使用默认的App Status＆amp;评论。但我认为这并不重要，因为我没有像Facebook那样登录Facebook。怎么了？请帮帮我。

感谢您的阅读。
