Question

我想使用nodemailer和node.js附加PDF文档，但是，我找到的与nodemailer附件的唯一示例是.txt文件（here）。

有没有人知道nodemailer是否支持PDF文档附件？

最初看起来可以附加PDF，但通过电子邮件到达的PDF文件似乎已损坏（见图）。

代码：（改编自Mahesh的回答）

fs.readFile('/filePath/fileName.pdf', function (err, data) {
if (err) throw err;                                                  
var mailOptions = {
    from: 'Test <formEmail@gmail.com>', // sender address                                   
    to: 'toPersonName <toEmail@gmail.com>', // list of receivers                                 
    subject: 'Attachment', // Subject line                                                 
    text: 'Hello world attachment test', // plaintext body                                                 
    html: '<b>Hello world attachment test HTML</b>', // html body                                               
    attachments: [
        {
            filename: 'fileName.pdf',                                         
            contentType: 'application/pdf'
        }]
};

// send mail with defined transport object                                                 
transporter.sendMail(mailOptions, function(error, info){
    if(error){
        return console.log(error);
    }
    console.log('Message sent: ' + info.response);
});
console.log(data);
});

终端响应：

Answer 1

是的，你可以。您必须添加要尝试附加的文件的路径。

transporter.sendMail({
  from: 'foo@bar.com',
  to: 'bar@foo.com',
  subject: 'An Attached File',
  text: 'Check out this attached pdf file',
  attachments: [{
    filename: 'file.pdf',
    path: 'C:/Users/Username/Desktop/somefile.pdf',
    contentType: 'application/pdf'
  }],
  function(err, info) {
    if (err) {
      console.error(err);
      res.send(err);
    } else {
      console.log(info);
      res.send(info);
    }
  }
});

Answer 2

是的，您可以将pdf文档附加到电子邮件中，获取可以使用path的路径，然后从当前文件到您要附加的pdf。这对我有用。

// node-mailer.js
const nodemailer = require('nodemailer');
const path = require('path');
...
const mailOptions = {
    from: '',
    to: '',
    subject: '',
    text: '',
    html: '',
    attachments: [
        {
            filename: 'file-name.pdf', // <= Here: made sure file name match
            path: path.join(__dirname, '../output/file-name.pdf'), // <= Here
            contentType: 'application/pdf'
        }
    ]
};

transporter.sendMail(mailOptions, function(error, cb) {

});

我的文件结构/树：

├── package-lock.json
├── package.json
├── output
│   └── file-name.pdf
├── routes
│   └── node-mailer.js <= Current file
└── server.js

希望这对某人有帮助:) 编码愉快！

Answer 3

请记住两点。

提供pdf文件的完整地址。您可以使用__dirname（见下文）

文件名和路径上的pdf名称应完全相同。

let info = await transporter.sendMail({
  from: '"Subject Foo Bar" <foo@bar.com>', // sender address
  to: `foo@bar.com, foofoo@bar.com`, // list of receivers
  subject: "Your's subject", // Subject line
  text: "Body of the email",
  attachments: [
    {
      filename: "Trial_Agreement.pdf",
      path: __dirname + "/Trial_Agreement.pdf",
    },
  ],
});

Answer 4

是的，很容易做到。我最近从事的项目需要类似的东西，对我来说很好。我使用Gmail在这里发送邮件。

导入Nodemailer

const nodemailer = require('nodemailer');

发送邮件的主要功能

const sendEmailWithPromiseWithDynamicData = async () => {        
    let mailOptions = mailOptionsForDynamicMail()
    return new Promise((resolve, reject) => {
    createEmailTranspoter().sendMail(mailOptions, async(error, info) => 
    {                      
        if (error) {
        reject(error);
    }
        resolve(info);
    });
  });
}

邮件选项功能

const mailOptionsForDynamicMail = async() => {            
            return {
                from: `"PROJECT NAME" <SENDER EMAIL ADDRESS>`, // sender address
                to: "RECEIVER EMAIL ADDRESS", // list of receivers
                subject: "Test Subject", // Subject line
                text: "Test Text", // plain text body
                html: generateEmailTemplateForDynamicMail(), // html body
                attachments: [
                    {   // utf-8 string as an attachment
                        filename: "YOUR ATTACHMENT FILE NAME", // file name, like 'test.pdf'
                        href: "LINK TO THE FILE" // link to the file, like http://example.com/invoices/test.pdf 
                    }
                ]
            };
        }
    }

创建邮件传输器

const createEmailTranspoter = () => {        
        return nodemailer.createTransport({
            host: 'smtp.gmail.com', //your smtp host name
            service: 'Gmail', // your service name
            port: 465,
            secure: true, // true for 465, false for other ports
            auth: {
                user: "SENDER MAIL",
                pass: "SENDER MAIL PASSWORD"
            },
            tls: {
                rejectUnauthorized: true
            }
        });
    
    }

邮件HTML正文

const generateEmailTemplateForDynamicMail = async() => {
            return `
      <h4>This is a test mail</h4>
      <h5>Testing for email Attachments</h5>
      <br>
      <br>
      <br>
      <p></p>
      <p>Thanks</p>
      <p>Test person</p>
      `;
}
