Question

我正在使用facebook api在我的网站上使用facebook的登录功能。但是它存在问题，登录后它没有重定向到我的网站。它重定向到Facebook主页。我不知道为什么会这样。我的代码如下：

此文件名为logign_facebook.php

<?php

require 'facebook/facebook.php';
require 'config/fbconfig.php';
require 'config/functions.php';

$facebook = new Facebook(array(
            'app_id' => APP_ID,
            'app_seceret' => APP_SECRET,
            ));

$user = $facebook->getUser();

if ($user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }

    if (!empty($user_profile )) {
        # User info ok? Let's print it (Here we will be adding the login and registering routines)

        $username = $user_profile['name'];
             $uid = $user_profile['id'];
         $email = $user_profile['email'];
        $user = new User();
        $userdata = $user->checkUser($uid, 'facebook', $username,$email,$twitter_otoken,$twitter_otoken_secret);
        if(!empty($userdata)){
            session_start();
            $_SESSION['id'] = $userdata['id'];
 $_SESSION['oauth_id'] = $uid;

            $_SESSION['username'] = $userdata['username'];
            $_SESSION['email'] = $email;
            $_SESSION['oauth_provider'] = $userdata['oauth_provider'];
            header("Location: home.php");
        }
    } else {
        # For testing purposes, if there was an error, let's kill the script
        die("There was an error.");
    }
} else {
    # There's no active session, let's generate one
    $login_url = $facebook->getLoginUrl(array( 'scope' => 'email'));
    header("Location: " . $login_url);
}
?>

请帮我解决这个问题。感谢

Facebook需要知道重定向到用户登录时的URL。

您可以通过PHP SDK中的 getLoginUrl（）函数传递此信息，如下所示：

$login_url = $facebook->getLoginUrl(array(
    'redirect_uri' => 'http://yoururlhere.com/logign_facebook.php',
    'scope'        => array('email')
));

可以在https://developers.facebook.com/docs/reference/php/facebook-getLoginUrl看到此功能的完整参数列表。

另一种解决方案：

https://developers.facebook.com/apps/

应用和GT;＆GT; [APP_NAME] GT;＆GT;基本

然后向下滚动到“使用Facebook登录的网站”

在文本字段中输入所需的网址。

登录Facebook无法正常工作
