目前im使用sendgrid使用nodejs库“(‘nodemailer’)”TransporterOption：

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);
}

工作顺利，没有任何问题。

在传递api_key以响应此错误时，从用户名/密码迁移到API键：“邮件命令失败:不允许550个未经身份验证的发件人”

备选案文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
        }
    },

“错误”：{“消息”：“缺少”“平原”的凭据“，”名称“：”错误“，”堆栈“：”错误:缺少“平原”的凭据\n

备选案文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
        }
    },

错误：“{”消息“：”邮件命令失败:550个未经身份验证的发件人不允许“，”名称“：”错误“，”堆栈“：”错误:邮件命令失败:550个未经身份验证的发件人不允许\n“

备选方案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
        }
    },

错误：“{”消息“：”邮件命令失败:550个未经身份验证的发件人不允许“，”名称“：”错误“，”堆栈“：”错误:邮件命令失败:550个未经身份验证的发件人不允许\n“

我还需要从基本身份验证迁移到Sendgrid的API密钥。

我试图以以下方式使用API密钥，并且可能有效，但不知道我们是否仍然以这种方式使用基本身份验证，这将很快由于强制2FA而失败。

如果我们在这里做的是对的，请告诉我。

// 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
}

您可以安装nodemailer-sendgrid包，然后创建如下所示的传输：

const nodemailer = require('nodemailer');
const nodemailerSendgrid = require('nodemailer-sendgrid');
const transport = nodemailer.createTransport(
    nodemailerSendgrid({
        apiKey: process.env.SENDGRID_API_KEY
    })
);
