无法使用 Oauth2 通过 Google cloud 发送节点邮件程序(响应代码：530)

Question

我已经配置了两个GMAIL帐户来集成nodemailer与Oauth2fromGoogle cloud当我第一次这样做时，我可以成功地从我的nodejs应用程序发送GMAIL的电子邮件。然而，今天我做了和以前一样的步骤，当我试图发送电子邮件时，它抛出了一个错误。

Error: Mail command failed: 530-5.7.0 Authentication Required

互联网上的一些答案说我需要在谷歌上激活不太安全的应用程序，但自2022年5月以来，这个选项被谷歌停用，所以我不能这样做。

在Google cloud上设置Oauth2的所有步骤(摘要):

1. 创建新项目

2. 已启用的服务和API

3. 在OAuth同意屏幕上创建新的Oauth2

4. 创建新的凭据，web应用程序，重定向:https://developers.google.com/oauthplayground

5. 新增测试用户在OAuth同意界面

6. oauthplayground选择"https://mail.google.com">服务并添加CLIENT_ID和CLIENT_SECRET，然后单击为令牌交换授权代码

这是相同的设置，我总是做当我需要配置nodejs与GMAIL，我应该工作，然后我复制所有必要的值到node.js CLIENT_ID, CLIENT_SECRET, refresh_tokens…

现在我想分别分享与nodemailer和googleapi相关的重要.js文件:

const nodemailer = require('nodemailer');
const urlUtil = require('../utils/urlUtil');
const config = require(urlUtil.getPath('../config.min.js'));
const googleApiUtil = require(urlUtil.getPath('../utils/googleApiUtil.min.js'));
/**
* Send generic email
* @param {*} destination to
* @param {*} subject title of the email
* @param {*} html html content for email template
* @returns promise
*/
function sendEmail(destination, subject, html) {
return new Promise((resolve) => {
googleApiUtil.getCredentials().then((credentials) => {
try {
let transporter = nodemailer.createTransport({
service: config.mail.service,
auth: {
type: 'OAuth2',
user: config.mail.user,
clientId: credentials.client_id,
clientSecret: credentials.client_secret,
refreshToken: credentials.refresh_token,
accessToken: credentials.accessToken
}, tls: {
rejectUnauthorized: false
}
});
let mailOptions = {};
mailOptions = {
from: `IARA <${config.mail.user}>`,
to: destination,
subject: subject,
html: html,
attachments: null
};
transporter.sendMail(mailOptions, resolve);
} catch (error) {
console.log(error);
}
});
});
}
//This should send an email to destinantion
sendEmail('[e-mail]','teste','testando').then(r=> {
console.log(r)
})
/**
* Exports
*/
module.exports = {
sendEmail
};

const {google} = require('googleapis');
const urlUtil = require('../utils/urlUtil');
const config = require(urlUtil.getPath('../config.min.js'));
const fsUtil = require(urlUtil.getPath('../utils/fsUtil.min.js'));
//Basic credentials
const CLIENT_ID = '4123123..';
const CLIENT_SECRET = 'GO...';
//https://developers.google.com/oauthplayground
const REDIRECT_URI = 'https://developers.google.com/oauthplayground';
let refresh_token = '';
let accessToken = '';
if (!config.mail.refresh_token) {
refresh_token = '1//...';
} else {
refresh_token = config.mail.refresh_token;
}
const oAuth2Client = new google.auth.OAuth2(CLIENT_ID, CLIENT_SECRET, REDIRECT_URI);

oAuth2Client.setCredentials({
refresh_token: refresh_token,
});
oAuth2Client.refreshAccessToken((err, tokens) => {
console.log(tokens)
accessToken = tokens['access_token'];
refresh_token = tokens['refresh_token'];
//Set Config
if (err) {
console.log(err);
}
config.mail.accessToken = accessToken;
config.mail.refresh_token = refresh_token;
fsUtil.updateCredentials(config);
});
/**
* @returns Get credentials
*/
async function getCredentials() {
return {
redirect_uri: REDIRECT_URI,
refresh_token: refresh_token,
client_id: CLIENT_ID,
client_secret: CLIENT_SECRET,
accessToken: accessToken
};
}

module.exports = {
getCredentials
};

结论:

我甚至不知道如果我的错误是在Oauth2配置或在Nodejs，我相信它是在谷歌云，但我不太确定，如果有人更有经验知道我如何解决它让我知道，谢谢很多

Answer 1

我刚刚解决了这个问题，这是我得到的最佳解决方案，每当我调用oAuth2Client.refreshAccessToken()函数时，我保存所有返回的凭据，例如refresh_token,access_token在配置文件(.json)上，所以当我调用发送电子邮件时，我从配置文件中更新了这些凭据。这其实很简单，抱歉在Stackoverflow上开了一个愚蠢的问题。
