node.js - 使用 PDFkit 通过 Nodemailer 发送 base64 编码的 PDF

Question

我有一个函数可以返回一个base64编码的PDF，我想使用nodemailer将其作为附件PDF文件发送。

关于nodemailer文档，我找到了这个例子:

const mailOptions = {
    from: '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="dcb9b1bdb5b0ed9cbbb1bdb5b0f2bfb3b1" rel="noreferrer noopener nofollow">[email protected]</a>', // sender address
    to: '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="adc8c0ccc4c19fedcac0ccc4c183cec2c0" rel="noreferrer noopener nofollow">[email protected]</a>', // list of receivers
    subject: 'Simulation', // Subject line
    html: '<p>SALUT</p>', // plain text body
    filename: 'file.pdf',
    attachments: [
          content: Buffer.from(
                'iVBORw0KGgoAAAANSUhEUgAAABAAAAAQAQMAAAAlPW0iAAAABlBMVEUAAAD/' +
                    '//+l2Z/dAAAAM0lEQVR4nGP4/5/h/1+G/58ZDrAz3D/McH8yw83NDDeNGe4U' +
                    'g9C9zwz3gVLMDA/A6P9/AFGGFyjOXZtQAAAAAElFTkSuQmCC',
                'base64'
            ),

            cid: '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="452b2a312005203d24283529206b262a28" rel="noreferrer noopener nofollow">[email protected]</a>' // should be as unique as possible
        },

但是，这对我不起作用。我错过了什么吗？

好吧，这都是格式问题。

以下是如何在 Nodemailer 上使用 B64:

  const mailOptions = {
    from: '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="62070f030b0e5322050f030b0e4c010d0f" rel="noreferrer noopener nofollow">[email protected]</a>', // sender address
    to: '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="03666e626a6f3143646e626a6f2d606c6e" rel="noreferrer noopener nofollow">[email protected]</a>', // list of receivers
    subject: "Hey this is a subject example", //subject
    attachments: [
      {
        filename: `myfile.pdf`,
        content: 'THISISAB64STRING',
        encoding: 'base64',
      },
    ],
  };

然后以经典方式发送即可。
