我使用作曲家下载了Hybrid Auth，并将index.php和config.php文件复制到了root。然后，我将index.php文件重命名为hybrid.php文件。我只是想从Facebook获取用户的电子邮件。
Auth.php抛出此异常：
致命错误：未捕获的异常：验证失败！脸书 返回了无效的用户ID。在C：\ xampp \ htdocs \ hybrid中 auth \ vendor \ hybridauth \ hybridauth \ hybridauth \ Hybrid \ Auth.php：153堆栈 跟踪：＃0 C：\ xampp \ htdocs \ hybrid auth \ vendor \ hybridauth \ hybridauth \ hybridauth \ Hybrid \ Auth.php（39）： Hybrid_Auth :: initialize（Array）＃1 C：\ xampp \ htdocs \ hybrid auth \ index.php（6）：Hybrid_Auth-> __ construct（'config.php'）＃2 {main} 抛出C：\ xampp \ htdocs \ hybrid 在线上的auth \ vendor \ hybridauth \ hybridauth \ hybridauth \ Hybrid \ Auth.php 153
混合身份验证调试文件：
我创建了一个新的index.php文件，如下所示：
<?php
require 'vendor/autoload.php';
$model = new \Model\App_Model();
$hybridInstance = new Hybrid_Auth('config.php');
$session_identifier = Hybrid_Auth::storage()->get( 'user' );
if (is_null( $session_identifier )) {
echo "redirect to login";
try {
$adapter = $hybridInstance->authenticate( ucwords('facebook') );
$user_profile = $adapter->getUserProfile();
if (empty( $user_profile )) {
echo "/login/?err=1";
}
$identifier = $user_profile->identifier;
if ($model->identifier_exists( $identifier )) {
$model->login_user( $identifier );
echo "welcome";
} else {
$register = $model->register_user(
$identifier,
