node.js - Nodejs Nodemailer : Sendgrid SMTP username & password to API key using existing code error : 550

Question

目前我正在使用使用 nodejs 库“('nodemailer')”的sendgrid转运选项:

配置:

 transporterOption: {
        host: process.env.SMTP_HOST, // smtp.sendgrid.net
        pool: true,
        maxConnections: 20,
        rateDelta: 1000,
        rateLimit: 150,        
        auth: {
            user: process.env.USER_NAME,
            pass: process.env.PASSWORD
        }
    },

发送代码:

const config = require('./config');
const nodeMailer = require('nodemailer');
const htmlToText = require('nodemailer-html-to-text').htmlToText;



const transporter = nodeMailer.createTransport(config.transporterOption);

transporter.use('compile', htmlToText());


try {

    let mailOptions = {
        headers: { 'X-SMTPAPI': `{"category":["${myid}"]}` },
        from: `"myname" <${toemail}>`,
        replyTo: `"myname" <${toemail}>`,
        to: `"name" <${emailAdr}>`,
        subject: mysubject,
        text: mytextbody,
        html: myhtmlbodymsg

    }
} catch (e) {

    console.log(e);
}

工作正常，没有问题。

从用户名/密码迁移到 API key 当传递 api_key 以响应收到此错误“邮件命令失败:550 未经身份验证的发件人不允许”

选项 1:

transporterOption: {
        host: process.env.SMTP_HOST, // smtp.sendgrid.net
        pool: true,
        maxConnections: 20,
        rateDelta: 1000,
        rateLimit: 150,        
        auth: {
            api_key: process.env.SENDGRID_API_KEY // fakeKEY.kashdkjhjkdhsakjdhksajhd
        }
    },

"err":{"message":"Missing credentials for"PLAIN"","name":"Error","stack":"Error: Missing credentials for"PLAIN"\n

选项 2:

transporterOption: {
        host: process.env.SMTP_HOST, // smtp.sendgrid.net
        pool: true,
        maxConnections: 20,
        rateDelta: 1000,
        rateLimit: 150,        
        auth: {
            Username: process.env.USER_NAME, //’apikey’
            Password: process.env.SENDGRID_API_KEY // fakekeyssssjhkjsahdkjsahdkjhsa
        }
    },

Error : “{"message":"Mail command failed: 550 Unauthenticated sendersnot allowed","name":"Error","stack":"Error: Mail command failed: 550Unauthenticated senders not allowed\n”

选项 3:

transporterOption: {
        host: process.env.SMTP_HOST, // smtp.sendgrid.net
        pool: true,
        maxConnections: 20,
        rateDelta: 1000,
        rateLimit: 150,        
        auth: {
            api_user: 'apikey',
        api_key: process.env.SENDGRID_API_KEY // fakekeyssssjhkjsahdkjsahdkjhsa
        }
    },

Error : “{"message":"Mail command failed: 550 Unauthenticated sendersnot allowed","name":"Error","stack":"Error: Mail command failed: 550Unauthenticated senders not allowed\n”

Answer 1

我还需要从基本身份验证迁移到 Sendgrid 的 API key 。
我尝试通过以下方式使用 API key ，并且可能有效，但不知道我们是否仍在通过这种方式使用基本身份验证，由于强制，很快就会失败2FA.
让我知道我们在这里所做的是否正确。

// This below auth object is specific to NODEMAILER configuration options
// This is NOT the same for sendgrid native API configuration

// you can try with your keys named Username/Password but mine works with user/pass
auth: {
  'user': 'apikey', // <--- keep as is
  'pass': 'SG.aslknwefn_RANDOM_FAKE_KEY', // <--- your api key
}
