是否可以在没有“安全性较低的应用程序”的情况下从node.js应用程序使用gmail

Question

我的帐户

LESS SECURED APPS

不支持。

我一直用这个，但现在不再用了。

const shared = require("./../common/shared");
const config = require("./../config");
const nodemailer = require('nodemailer')

class Sender {
  constructor(to, subject, content) {
    this.userId = shared.formatUserKeyLiteral(to);
    this.subject = subject;
    this.to = to;
    this.content = content;
  }

  async SEND(subject) {

    let arg = {
      user: "[email protected]",
      pass: "***",
      to: this.to,
      subject: this.subject,
      html: this.content
    }

    console.log('EMAIL')

    const transporter = nodemailer.createTransport({
      service: "gmail",
      host: "smtp.gmail.com",
      port: 587,
      secure: false,
      auth: {
        user: "[email protected]",
        pass: "****",
      }
  });

  transporter.verify(function (error, success) {
    if(error) {
        console.log("NOT PREPARE EMAIL !!!!" + error);
    } else {
        console.log('Server validation done and ready for messages.')
    }
});

const email = {
  from: '[email protected]',
  to: '[email protected]',
  subject: 'ROCKET',
  text: 'Now is the time for all good men to send Email via Node.js!'
};

  transporter.sendMail(email, function(error, success){
    if (error) {
        console.log('>>>>>>>>>>>>>>>>>' + error);
    } else {
        console.log('Nodemailer Email sent: ' + success.response);
    }
});



    // return new Promise((resolve, reject) => {
    //   this.GM = require("gmail-send")(arg);
    //   this.GM((
    //     subject
    //     // files: [filepath],
    //   ), function(err, res) {
    //     if (err != null) { reject(err); }
    //     resolve(res);
    //   });
    // });

  }

}
module.exports = (to, subject, content) => { return new Sender(to, subject, content) }

Answer 1

问题是，从 2022 年 5 月 30 日起，安全性较低的应用程序不再支持 Gmail。现在，Gmail API 使用带有令牌的 OAuth2 身份验证进行身份验证，以帮助确保帐户安全。

Google 不再支持使用要求您仅使用用户名和密码登录 Google 帐户的第三方应用或设备。

这里是来自 Google 文档的 OAuth2 身份验证实现的快速入门指南。
