通过 html 表单使用 nodemailer 发送 PDF 文件

Question

我有一个表单，其中包含上传文件输入。我希望用户能够上传他们的文件并通过表单发送。目前 PDF 文件显示在电子邮件中，但不包含任何数据且无法打开等。

这是我目前在 nodemailer 选项中的内容：

let mailOptions = {
    from: '"Macwear Clothing" <shop@macwearclothing.com>', // sender address
    to: req.body.email, // list of receivers
    subject: 'Order Review', // Subject line
    text: 'Order Acception', // plain text body
    html: output, // html body
    attachments: [{'filename': 'needlesheet.pdf', 'content': req.body.needle, 'contentType': 'application/pdf'
  }]
};

客户端index.ejs文件

<div class="fileUpload up<%= item.number %>" id="m<%= item.number %>">
    <div class="fileUploadContent">
        <h2>Customer:
            <%= item.email %>
        </h2>
        <div class="uploadFile">
            <input id="needle" type="file" name="needle" value="Upload File &gt;">
        </div>
        <form method="POST" action="send" name="sendNeedleSheet" enctype="multipart/form-data">
            <div class="optionalMessage">
                <span>Optional Message:</span>
                <textarea class="customTextArea" name="message"></textarea>
                <input id="email" name="email" type="hidden" value="<%= item.email %>">
            </div>
            <div class="modalOptions">
                <div class="mButton ok">
                    <button class="customButton" type="submit">Send</button>
                 </div>
                <div class="mButton cancel">
                    <span>Cancel</span>
                </div>
           </div>
      </form>

Answer 1

我只是使用Multer 来处理文件的上传。只需要设置多个上传目录即可。

var upload = multer({dest: './public/uploads/'});

然后在 /send 路由中添加 upload.single('needle') 并删除箭头函数：

app.post('/send', upload.single('needle'), function (req, res, next) {

});

然后在邮件选项的附件中：

attachments: [
  {
      filename: req.file.originalname,
      path: req.file.path

  }

]

最后，将 HTML 表单上的 enctype 设置为 multipart/form-data 很重要，否则无法通过 multer 上传文件。

Answer 2

您为附件和静态路径都使用了路径，因此文档将不会显示其扩展名

尝试：

app.use(express.static('public'))
