NodeEmailer和GMail OAuth：不接受用户名和密码

Question

所以我有以下代码：

const nodemailer = require("nodemailer");

const mailer = {
    service: "gmail",
    auth: {
        type: "OAuth2",
        user: "[e-mail]",
        clientId: "123123123123123123123123123123.apps.googleusercontent.com",
        clientSecret: "krW123123123123123123RqEnS",
        refreshToken: "1/SM-7f31231231231231231231231231231231231231231231231UzH",
        accessToken: "ya29.1234568791231324564897894231324564697897ss3Ggi-TkWO4HSIZBqHiLpoIkT7H_Sgii4RQxyVJ0QjIfjKB5zk"
    }
}

const transporter = nodemailer.createTransport(mailer);
transporter.sendMail({
    to: "[e-mail]",
    subject: "test",
    text: "test"
});

但当我尝试发送电子邮件时，它总是给出如下错误：错误：无效登录：535-5.7.8用户名和密码不被接受。在535 5.7.8了解更多信息https://support.google.com/mail/?p=BadCredentialsf67-v6sm75536287pfe。75-gsmtp
