Node.js 如何使用NodeJs（sendgird）从url附加pdf

我想将url附加到电子邮件中，我使用了一些解决方案，例如通过请求获取pdf url或将其作为文件读取，但不起作用

const sgMail = require('@sendgrid/mail');
sgMail.setApiKey("XXXXXXXXXXXXXXXXXXXXXXXXXXXXX");

var array = [],
    temp = [];

array.push('https://www.antennahouse.com/XSLsample/pdf/sample-
link_1.pdf');

array.push('https://www.antennahouse.com/XSLsample/pdf/sample-
link_1.pdf');

array.forEach(function(data) {
   temp.push({
      path: data,
      filename: 'hello.pdf'
  });

  const msg = {
    to: 'example@example.com',
    from: 'example@example.com',
    subject: 'Test',
    text: 'this is test',
    html: '<strong>Hello World</strong>',
    attachments: temp,
  };

  if ( temp.length == array.length )
      sgMail.send(msg);
  });

const sgMail=require（'@sendgrid/mail'）；
sgMail.setApiKey（“xxxxxxxxxxxxxxxxxxxxxxxx”）；
变量数组=[]，
温度=[]；
array.push（'https://www.antennahouse.com/XSLsample/pdf/sample-
链接_1.pdf'）；
array.push（'https://www.antennahouse.com/XSLsample/pdf/sample-
链接_1.pdf'）；
array.forEach（函数（数据）{
临时推力({
路径：数据，
文件名：“hello.pdf”
});
常数msg={
致：'example@example.com',
发件人：'example@example.com',
主题：“测试”，
文本：“这是测试”，
html:“你好，世界”，
附件：临时工，
};
if（temp.length==array.length）
sgMail.send（msg）；
});

我们有来自的示例。注意：内容必须是字符串base64编码的

const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
  to: 'recipient@example.org',
  from: 'sender@example.org',
  subject: 'Hello attachment',
  html: '<p>Here’s an attachment for you!</p>',
  attachments: [
    {
      content: 'Some base 64 encoded attachment content',
      filename: 'some-attachment.pdf',
      type: 'application/pdf',
      disposition: 'attachment',
      contentId: 'mytext'
    },
  ],
};

const sgMail=require（'@sendgrid/mail'）；
sgMail.setApiKey（process.env.SENDGRID\u API\u KEY）；
常数msg={
致：'recipient@example.org',
发件人：'sender@example.org',
主题：“你好，附件”，
html:“这是给你的附件！
”，
附件:[
{
内容：“一些基本64编码的附件内容”，
文件名：“some attachment.pdf”，
键入：“application/pdf”，
处置：'附件'，
contentId:“mytext”
},
],
};

这是我的有效解决方案。您可以使用请求npm模块从任何源读取pdf文件，但不要错过{encoding:null}

const sgMail = require('@sendgrid/mail');
var request = require('request');
request.get('https://someurl/output.pdf',{ encoding: null },(err,res) => {
  console.log(res);
  var base64File = new Buffer(res.body).toString('base64');

  sgMail.setApiKey('yourSendgridApiKey');
  const msg = {
    to: 'to@mail.com',
    from: 'from@mail.com',
    subject: 'Sending with SendGrid is Fun',
    text: 'and easy to do anywhere, even with Node.js',
    attachments: [
      {
        content: base64File,
        filename: 'some.pdf',
        ContentType: 'application/pdf',
        disposition: 'attachment',
        contentId: 'mytext'
      },
    ]
  }
  sgMail.send(msg, (error, data) => {
    if (error) {
      console.log('error', error)
    } else {
      console.log('successfully sent email' + data);
    }
  });
})

根据，似乎您想要的（附加url）不受支持。（请查看

附件

部分）。您可以使用

content

property下载文件并附加。如果您需要有关下载文件并附加其内容的帮助，请告诉我。

const sgMail = require('@sendgrid/mail');
const pdf2base64 = require('pdf-to-base64'); 
sgMail.setApiKey(apiKey); 
const body = await sgMail.send({
      to: email,
      from,
      subject: "subject",
      html: "hello welcome",
      ...(
        attachments && attachments.length && {
          attachments:attachments.map(attachment=>({
            content: attachment,
            filename: "attachment.pdf",
            type: "application/pdf",
            disposition: "attachment"
          }))
        }
      )
    });
     return body;
