服务器在 phpmailer 获取 oauth 令牌文件时返回 500 错误

Question

当我尝试访问phpmailer/get_outh_token.php 以获取refresh token 服务器返回时：

HTTP 错误 500

Client ID、Secret key 和 redirect Uri 是正确的，我已经在 Wordpress 中使用它。

我已经下载了最新版本的phpmailer，也用旧版本进行了测试，结果相同。

我找到原因了，就是这部分：

namespace League\OAuth2\Client\Provider;

当我删除它时，脚本当然会加载错误，因为

未加载提供程序命名空间。

网站正在使用PHP 7.

这是get_outh_token.php的完整代码，是原创的（当然只是凭证不同）：

<?php
error_reporting(E_ALL);
ini_set('display_errors', 'On');
/**
 * Get an OAuth2 token from Google.
 * * Install this script on your server so that it's accessible
 * as [https/http]://<yourdomain>/<folder>/get_oauth_token.php
 * e.g.: http://localhost/phpmail/get_oauth_token.php
 * * Ensure dependencies are installed with 'composer install'
 * * Set up an app in your Google developer console
 * * Set the script address as the app's redirect URL
 * If no refresh token is obtained when running this file, revoke access to your app
 * using link: https://accounts.google.com/b/0/IssuedAuthSubTokens and run the script again.
 * This script requires PHP 5.4 or later
 * PHP Version 5.4

我知道这个问题很老，但我遇到了同样的问题。 我所做的只是通过 composer 安装 League/oauth2-google

composer require league/oauth2-google

This helped me figure it out

希望对其他人有所帮助。
