Question

我正在尝试使用OAuth2通过Gmail发送电子邮件。

我已完成此处描述的所有步骤：https://github.com/PHPMailer/PHPMailer/wiki/Using-Gmail-with-XOAUTH2

唯一的区别是默认情况下 get_oauth_token.php 请求离线访问，并且在指南中他们没有说明更改此内容，但是在屏幕截图上请求“查看和管理您的邮件“而不是”离线访问“。但是好的，我正在授权一个将来发送电子邮件但没有提示许可的应用程序，所以我认为“离线”正是我需要的。

但问题是，当我使用所有获得的凭据发送电子邮件时，它会失败。这是我的PHP代码：

<?php

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\OAuth;
use League\OAuth2\Client\Provider\Google;

date_default_timezone_set('Etc/UTC');
require 'vendor/autoload.php';

$mail = new PHPMailer;
$mail->isSMTP();
$mail->SMTPDebug = 2;
$mail->Debugoutput = 'html';

$mail->Host = 'smtp.gmail.com';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->AuthType = 'XOAUTH2';

$email = 'hello@otdelkalux.ru';
$clientId = '407883698840-47e4rhg839eh8fm3qsfuva8b46acnl36.apps.googleusercontent.com';
$clientSecret = 'xr1Q08dGYjpSFLrwWB7laBb3';
$refreshToken = '1/JRTle_utTpfG4Mz_Z1fQiCf-qrNXzkS2PDg4iaqSHa4';

//Create a new OAuth2 provider instance
$provider = new Google([
    'clientId' => $clientId,
    'clientSecret' => $clientSecret
]);

//Pass the OAuth provider instance to PHPMailer
$mail->setOAuth(
    new OAuth([
        'provider' => $provider,
        'clientId' => $clientId,
        'clientSecret' => $clientSecret,
        'refreshToken' => $refreshToken,
        'userName' => $email
    ])
);

$mail->addAddress('mike.shestakov@gmail.com');     // Add a recipient
$mail->isHTML(true);                               // Set email format to HTML

$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

以下是服务器响应的内容：

它说用户名和密码不被接受;但是，我没有使用任何密码。

我错过了什么？谢谢！

更新：我已尝试过6.0分支，但失败的结果完全相同。我已经用新的代码替换了代码示例和日志（上图）。真实的凭据在代码中，所以如果你@synchro可以重现这个问题并帮助解决它，那将非常感激！
