未设置刷新令牌或刷新处理程序回调

Question

我正在尝试使用 Nodemailer 和 OAuth2 发送电子邮件。它在 localhost 但不在 Heroku 上工作，所以我将 OAuth 添加到 Nodemailer createTransport。但现在它甚至在 localhost 上也不起作用。

我的代码是：

const oAuth2Client =new google.auth.OAuth2(process.env.CLIENT_ID,process.env.CLIENT_SECRET,process.env.REDIRECT_URI);
oAuth2Client.setCredentials({refresh_token:process.env.REFRESH_TOKEN});

const sendMail =async(email,code)=>{
    try
    {const accessToken = await oAuth2Client.getAccessToken();
    let transport = nodemailer.createTransport(smtTransport({
        service: "gmail",
        auth: {
            type:"OAuth2",
            user: "kediaarts@gmail.com",
            pass: process.env.EMAIL_PASS,
            clientId:process.env.CLIENT_ID,
            clientSecret:process.env.CLIENT_SECRET,
            refreshToken:process.env.REFRESH_TOKEN,
            accessToken:accessToken
        }
    }));

    let mailOptions,link;

   link = "http://localhost:5000"+email+"/"+code.toString() ;
    mailOptions={
        from:'"Horizons" <no-reply@gmail.com>',
        to : email,
        subject: "Please verify your Email",
        html : "<h1>Horizons</h1><br><h2>Hi,<br> Please click on the link to verify your email.</h2><br><a href="+link+">Click here to verify</a>",
    }
    const result =await transport.sendMail(mailOptions);
    return result;

} catch(error){
    console.log(error);
}
    
}

我收到以下错误：

Error: No refresh token or refresh handler callback is set.

问题是没有填充 process.env.REFRESH_TOKEN 主要是因为您没有配置 dotenv。

添加这个来填充它：

import dotenv from "dotenv";

// *Useful for getting environment vairables
dotenv.config();
