javascript - 如何使用@sendgrid/mail 发送 zip 文件

Question

这是我编写的使用@sendgrid 发送带附件的电子邮件的代码

  const mailOptions = {}
  if(mailOptions){
    mailOptions.from = 'APP NAME'
    mailOptions.to = 'emailId'
    mailOptions.subject = 'Subject' // Subject line
    //mailOptions.attachments = attachments
    mailOptions.text = 'attachments'
  }
  const sendEmail = await sgMail.send(mailOptions)

但它只发送主题为“无附件”的邮件

取消注释 attachment 行时出现的错误

{ Error: Bad Request
    at Request.http [as _callback] (node_modules/@sendgrid/client/src/classes/client.js:124:25)

为什么会发生这种情况，谁能帮帮我。

这个问题已经有一段时间了，但回答以备将来引用。

为了修复错误，附件必须采用 Base64 编码 - 并且其文件类型应设置为“application/zip”。要输入的 .js 代码也已大大更新。今天的示例如下所示

const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);

const fs = require("fs");

pathToAttachment = `${__dirname}/attachment.zip`;
attachment = fs.readFileSync(pathToAttachment).toString("base64");

const msg = {
  to: 'test@example.com',
  from: 'test@example.com',
  subject: 'Subject',
  text: 'Sent using Node.js',
  attachments: [{
    content: data.toString('base64'),
    filename: filename,
    type: fileType,
    disposition: 'attachment',
  }, ],
};
sgMail.send(msg).catch(err => {
  console.log(err);
});

编码愉快!
