Facebook 连接权限 PHP SDK

Question

我尝试建立与 Facebook Connect 的连接，处理很顺利，我可以检索用户名和 ID，但未考虑 $ 权限中传输的信息。我会忘记一件事吗？我遵循了 Facebook 开发人员提供的文档。我用的是最新版本：PHP SDK 5.2

public function facebook() {
    session_start();
    require '../Vendor/autoload.php';
    $fb = new Facebook\Facebook([
        'app_id' => 'ID_APP',
        'app_secret' => 'SECRET_APP',
        'default_graph_version' => 'v2.5',
    ]);
    $helper = $fb->getRedirectLoginHelper();
    $permissions = ['email', 'user_location','user_birthday']; // optional
    $loginUrl = $helper->getLoginUrl('http://localhost/Weade/connexion/check_facebook', $permissions);

    $this->redirect($loginUrl);


}

public function check_facebook() {
    session_start();
    require '../Vendor/autoload.php';
    $fb = new Facebook\Facebook([
        'app_id' => 'APP_ID',
        'app_secret' => 'APP_SECRET',
        'default_graph_version' => 'v2.5',
    ]);
    $helper = $fb->getRedirectLoginHelper();
    try {
        $accessToken = $helper->getAccessToken();
    } catch(Facebook\Exceptions\FacebookResponseException $e) {
        // When Graph returns an error
        echo 'Graph returned an error: ' . $e->getMessage();
        exit;
    } catch(Facebook\Exceptions\FacebookSDKException $e) {
        // When validation fails or other local issues
        echo 'Facebook SDK returned an error: ' . $e->getMessage();
        exit;
    }

    if (isset($accessToken)) {
        // Logged in!
        $_SESSION['facebook_access_token'] = (string) $accessToken;

        // Now you can redirect to another page and use the
        // access token from $_SESSION['facebook_access_token']
    }

    if($this->Session->read('facebook_access_token')) {
        $fb->setDefaultAccessToken($this->Session->read('facebook_access_token'));

        try {
            $response = $fb->get('/me');
            $userNode = $response->getGraphUser();
            debug($userNode);


        } catch(Facebook\Exceptions\FacebookResponseException $e) {
            // When Graph returns an error
            echo 'Graph returned an error: ' . $e->getMessage();
            exit;
        } catch(Facebook\Exceptions\FacebookSDKException $e) {
            // When validation fails or other local issues
            echo 'Facebook SDK returned an error: ' . $e->getMessage();
            exit;
        }

    }

}

谢谢，

Answer 1

$response = $fb->get('/me?fields=emai,user_location,user_birthday');

您必须定义要在请求中检索的字段，例如 /me?fields=id,name,email,birthday 而不仅仅是 /me

见 https://developers.facebook.com/docs/apps/changelog#v2_4

为了尝试提高移动网络的性能，v2.4 中的节点和边缘要求您明确请求 GET 请求所需的字段。例如 GET /v2.4/me/feed 默认不再包含点赞和评论，但是 GET /v2.4/me/feed?fields=comments,likes 将 return 数据。有关更多详细信息，请参阅有关如何请求特定字段的文档。
