Question

我有一个带有输入上传文件的表格。我希望用户能够上传他们的文件并通过表格发送它。目前，PDF文件显示为电子邮件中的附件，但不包含任何数据，也无法打开等。

这是我目前在nodemailer选项中拥有的：

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处理文件的上传。所需要做的就是设置multer上传目录。

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

然后在/ send路由中，添加upload.single（'needle'）并删除箭头功能：

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

});

然后在mailOptions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，否则通过multer上传的文件将无法工作。

Answer 2

您对附件和静态路径都使用了路径，因此文档不会显示其扩展名

试试：

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

通过HTML表单使用nodemailer发送PDF文件
