包括在VAR mailOption关键附件,如下图:

var mailOptions = {
...
attachments: [
    {   // utf-8 string as an attachment
        filename: 'text1.txt',
        content: 'hello world!'
    },
    {   // binary buffer as an attachment
        filename: 'text2.txt',
        content: new Buffer('hello world!','utf-8')
    },
    {   // file on disk as an attachment
        filename: 'text3.txt',
        path: '/path/to/file.txt' // stream this file
    },
    {   // filename and content type is derived from path
        path: '/path/to/file.txt'
    },
    {   // stream as an attachment
        filename: 'text4.txt',
        content: fs.createReadStream('file.txt')
    },
    {   // define custom content type for the attachment
        filename: 'text.bin',
        content: 'hello world!',
        contentType: 'text/plain'
    },
    {   // use URL as an attachment
        filename: 'license.txt',
        path: 'https://raw.github.com/andris9/Nodemailer/master/LICENSE'
    },
    {   // encoded string as an attachment
        filename: 'text1.txt',
        content: 'aGVsbG8gd29ybGQh',
        encoding: 'base64'
    },
    {   // data uri as an attachment
        path: 'data:text/plain;base64,aGVsbG8gd29ybGQ='
    }
]

}

选择调整到您需要的选项。

我测试过的每这些附件的方法,没有是确定适合我。这里是没有SMTP传输配置我的邮件功能的代码:

function mailer(from, to, subject, attachments, body) {

    // Setup email
    var mailOptions = {
        from: from,
        to: to,
        subject: subject,
        attachments: attachments,
        html: body
    };

    // send mail with defined transport object
    smtpTransport.sendMail(mailOptions, function(error, response){
        if(error) console.log(error);
        else console.log("Message sent: " + response.message);
        // shut down the connection pool, no more messages
        smtpTransport.close();
    });
}

然后调用:

var attachments = [{ filename: 'test.pdf', path: __dirname + '/pdf/test.pdf', contentType: 'application/pdf' }];
mailer("[email protected]", "[email protected]", "Test", attachments, "<h1>Hello</h1>");

邮件来自成功,但没有附着物。即使我设置一个字符串或缓冲区附件是同样的结果。

如果您是通过选择在邮件撰写Constructor对象和依恋是HTTP服务器上,那么它应该是这样的:

const options = {
    attachments = [
      { // use URL as an attachment
        filename: 'xxx.jpg',
        path: 'http:something.com/xxx.jpg'
      }
    ]
}

该替代解决方案是在线托管图片使用CDN并链接到你的HTML,例如在线图像源。 <img src="list_image_url_here">

(我不得不使用nodemailer 2.6.0版,这就是为什么我想通了,这种解决方法nodemailer的形象嵌入的问题。)

这种方案的好处是,你不发送附件nodemailer,所以发送过程更加简化。

var express = require('express');
var router = express(),
multer = require('multer'),
upload = multer(),
fs = require('fs'),
path = require('path');
nodemailer = require('nodemailer'),

directory = path.dirname("");
var parent = path.resolve(directory, '..');
// your path to store the files
var uploaddir = parent + (path.sep) + 'emailprj' + (path.sep) + 'public' + (path.sep) + 'images' + (path.sep);
/* GET home page. */
router.get('/', function(req, res) {
res.render('index.ejs', {
    title: 'Express'
});
});

router.post('/sendemail', upload.any(), function(req, res) {

var file = req.files;
console.log(file[0].originalname)
fs.writeFile(uploaddir + file[0].originalname, file[0].buffer,     function(err) {
    //console.log("filewrited")
    //console.log(err)
})
var filepath = path.join(uploaddir, file[0].originalname);
console.log(filepath)
    //return false;
nodemailer.mail({
    from: "yourgmail.com",
    to: req.body.emailId, // list of receivers
    subject: req.body.subject + " ✔", // Subject line
    html: "<b>" + req.body.description + "</b>", // html body
    attachments: [{
        filename: file[0].originalname,
        streamSource: fs.createReadStream(filepath)
    }]
});
res.send("Email has been sent successfully");
})
module.exports = router;

var mailer = require('nodemailer');
mailer.SMTP = {
    host: 'host.com', 
    port:587,
    use_authentication: true, 
    user: '[email protected]', 
    pass: 'xxxxxx'
};

Then read a file and send an email :

fs.readFile("./attachment.txt", function (err, data) {

    mailer.send_mail({       
        sender: '[email protected]',
        to: '[email protected]',
        subject: 'Attachment!',
        body: 'mail content...',
        attachments: [{'filename': 'attachment.txt', 'content': data}]
    }), function(err, success) {
        if (err) {
            // Handle error
        }

    }
});

您的代码几乎是正确的,只需要添加,“附件”属性为您的邮件文件附加,

您的邮件选项:

var mailOption = {
        from: from,
        to:  to,
        subject: subject,
        text: text,
        html: html
}

只需添加附件一样

var mailOption = {
        from: from,
        to:  to,
        subject: subject,
        text: text,
        html: html,
        attachments: [{
            filename: change with filename,
            path: change with file path
        }]
}

附件还提供了一些其他的方式来连接文件的详细信息检查nodemailer社会的文档HERE
