Question

即使在运输对象中定义了速率限制，我仍然遇到节流错误。我在哪里缺少？

const nodemailer = require('nodemailer'); 
const ses = require('nodemailer-ses-transport');
const transporter = nodemailer.createTransport(ses({
    accessKeyId: "sesKeys_pub",
    secretAccessKey: "sesKeys_pvt",
    region : 'us-west-2',
    rateLimit: 5
}));
transporter.sendMail({
    from: "abc@xyz.com",
    to: "abc@xyz.com",
    subject: "sample",
    html: "<p>html</p>"
}

Answer 1

您的代码中有错误，应使用sendingRate

文档：https://nodemailer.com/transports/ses/#example-2

const nodemailer = require('nodemailer');
const aws = require('aws-sdk');

const transporter = nodemailer.createTransport(
SES: new aws.SES({
    accessKeyId: "sesKeys_pub",
    secretAccessKey: "sesKeys_pvt",
    region : 'us-west-2',
  }),
    sendingRate: 5
);

Answer 2

您需要设置singingRate，然后照常使用sendMail。

transporter = nodemailer.createTransport({
  SES: { ses, aws },
  sendingRate: 14,
});

const params = {
  from: 'EMAIL',
  to: 'EMAIL',
  subject: 'Message',
  html: 'I hope this <b>message</b> gets sent!',
  text: 'I hope this message gets sent!',
  // attachments: [{ filename: 'card.pdf', content: data, contentType: 'application/pdf' }],
};

transporter.sendMail(params, (err, info) => {
  if (err) {
    console.log(JSON.stringify(err));
  }
  console.log(info.envelope);
  console.log(info.messageId);
});

这里需要注意的重要一点是，nodemailer 等待下一秒继续处理下一批受限制的电子邮件和下一批，依此类推。因此，如果您运行的脚本在调用最后一个 sendMail() 后立即退出，则将永远不会发送受限制的电子邮件。通过在空闲时侦听或使用 settimeout 来确保该过程一直运行，直到所有电子邮件都发送完毕。

即使定义了速率限制，Nodemailer SES节流错误？
