[英]Fatal Error - Class 'League\OAuth2\Client\Provider\AbstractProvider' not found (phpMailer)
I installed league/oauth2-client
with composer and it created this line in composer.json
我用composer安装了league/oauth2-client
,它在composer.json
创建了这一行
"league/oauth2-client": "2.2.0" “league / oauth2-client”:“2.2.0”
When I refreshed get_oauth_token.php
page, this error still came out: 当我刷新get_oauth_token.php
页面时,这个错误仍然出现了:
Fatal error: Class 'League\\OAuth2\\Client\\Provider\\AbstractProvider' not found in C:\\xampp\\htdocs...\\PHPMailer\\get_oauth_token.php on line 35 致命错误:第35行的C:\\ xampp \\ htdocs ... \\ PHPMailer \\ get_oauth_token.php中找不到类'League \\ OAuth2 \\ Client \\ Provider \\ AbstractProvider'
Here's get_oauth_token.php
这是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
* PHP Version 5.4

Can you explain me in detail what to do after having installed league/oauth2-client
through composer require league/oauth2-client
? 你可以通过composer require league/oauth2-client
安装league/oauth2-client
之后详细解释一下我该做什么吗? Thank you. 谢谢。
Had a similar issue and discovered its not stated explicitly in the official tutorial here . 有一个类似的问题,发现它没有在这里的官方教程中明确说明。 The library league/oauth2-client requires you to install the provider you need seperately as there are multiple providers both official and third party here . 图书馆联盟/ OAuth2用户的客户端需要你,因为有多个供应商的官方和第三方安装你所需要的供应商seperately 这里 。
For google provider you would need 对于Google提供商,您需要
composer require league/oauth2-google
And refer to it like this 并且像这样参考它
use League\OAuth2\Client\Provider\Google;
