致命錯誤 -

Question

我安裝league/oauth2-client與作曲家和它composer.json

"league/oauth2-client": "2.2.0"

創造了這個線的時候我刷新get_oauth_token.php頁面級聯賽\ OAuth2用戶\客戶端\供應商\ AbstractProvider'未找到（PHPMailer的），這個錯誤還是出來了：

Fatal error: Class 'League\OAuth2\Client\Provider\AbstractProvider' not found in C:\xampp\htdocs...\PHPMailer\get_oauth_token.php on line 35

這裏的get_oauth_token.php

<?php 
/** 
* 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

你能否詳細解釋一下在通過composer require league/oauth2-client安裝league/oauth2-client後應該怎麼做？ 謝謝。

有一個類似的問題，並發現它沒有在官方教程here明確說明。 圖書館聯盟/ oauth2-client需要您安裝您需要單獨提供的提供商，因爲有多個提供商都是官方和第三方here。

對於谷歌提供你需要

composer require league/oauth2-google 

，並參考它像這樣

use League\OAuth2\Client\Provider\Google;
