如何使用SES服务在lambda nodeJs中发送带有附件的邮件

Question

我正试图发送一封带有附件的邮件。我已经使用SES服务发送简单和超文本标记语言的内容邮件。但是现在我想发送带有附件的邮件。

我正在使用亚马逊SES服务发送电子邮件，我正在使用sendRawEmail方法发送带有附件的邮件。

我收到这样的错误消息<代码>InvalidParameterValue:嵌套组

我没有找到任何此类错误的节点示例。

我有一个非常令人沮丧的时间试图用NodeJS SES API发送电子邮件。我发现了这个问题，我修复了使用mail作曲家npm包。现在我可以发送带有附件的邮件了。

安装AWS SDK

npm i aws-sdk

现在安装manil作曲家

npm i mailcomposer

完整代码如下

请求正文：如果要发送带有Base64内容的邮件。

{
  email: ['jen****@gmail.com', 'Aa****@gmail.com'],
  from: 'no-reply@*****.com',
  subject: 'Sending emails with attachments',
  text: 'please find attachments',
  attachments: [{
    filename: 'sample.pdf',
    content: {{file}}, // file content base64 staring
    encoding: 'base64',
  }]
}

如果要发送带有文件路径的邮件。

{
      email: ['jen****@gmail.com', 'Aa****@gmail.com'],
      from: 'no-reply@*****.com',
      subject: 'Sending emails with attachments',
      text: 'please find attachments',
      attachments: [{
        filename: 'sample.pdf',
        path: './home/sample,pdf'
      }]
    }

业务逻辑代码：

const ses = new AWS.SES({ region: 'us-east-1' }); //specify region for the particular see service.

const mailcomposer = require('mailcomposer');

exports.handler = function (event, context) {
  console.log('Event: ',JSON.stringify(event));

  if (!event.email) {
    context.fail('Missing argument: email');
    return;
  }

  if (!event.subject) {
    context.fail('Missing argument: subject');
  }

  if (!event.from) {
    context.fail('Missing argument: from');
  }

  if (!event.html && !event.text) {
    context.fail('Missing argument: html|text');
  }

  const to = event.email;
  const from = event.from;
  const subject = event.subject;
  const htmlBody = event.html; 
  const textBody = event.text;
  const attachments = event.attachments;

  const mailOptions = {
    from: from,
    subject: subject,
    text: textBody,
    html: htmlBody,
    to: to,
    attachments: attachments ? attachments : []
  };

  const mail = mailcomposer(mailOptions);

  mail.build(function (err, message) {
    const req = ses.sendRawEmail({ RawMessage: { Data: message } });

    req.on('build', function () {
      req.httpRequest.headers['Force-headers'] = '1';
    });

    req.send(function (err, data) {
      if (err) {
        console.log(err, err.stack);
        context.fail('Internal Error: The email could not be sent.');
      } else {
        console.log(message);
        console.log('The email was successfully sent')
        context.succeed('The email was successfully sent');
      }
    });
  });
};
