node-sparkpost 不包括电子邮件中的附件

Question

我正在尝试发送带有node-sparkpost 附件的电子邮件（在后台使用transmissions API）。

为什么下面的代码会发送邮件，但没有附件？

"use strict";
let Sparkpost = require("sparkpost");
let apiKey = "xxx";
let fromAddress = "dan@example.com";
let toAddress = "dare@example.com";

let spClient = new Sparkpost(apiKey);

spClient.transmissions
  .send({
    options: {},
    content: {
      from: fromAddress,
      subject: "The subject",
      html: "See attached file.",
      text: "See attached file."
    },
    recipients: [{ address: toAddress }],
    attachments: [
      {
        name: "attachment.json",
        type: "application/json",
        data: Buffer.from("{}").toString("base64")
      }
    ]
  })
  .then(data => {
    console.log("email mail sent");
    console.log(data);
  })
  .catch(err => {
    console.log("email NOT sent");
    console.log(err);
  });

一个经典的自我橡胶闪避时刻。

attachments 属性必须是 content 的子属性：

    content: {
      from: fromAddress,
      subject: "The subject",
      html: "See attached file.",
      text: "See attached file.",
      attachments: [
        {
          name: "attachment.json",
          type: "application/json",
          data: Buffer.from("{}").toString("base64")
        }
      ]
    },
