  代码与示例中给出的代码非常相似。你只需将 form.parse 放在路线中，就像在这个例子中一样

  var path = require('path');
      var express = require('express');
      var multiparty = require('multiparty');
      var util = require('util');
  
      var app = express();
  
      /*var staticPath = path.resolve(__dirname, '/public');
      app.use(express.static(staticPath));*/
  
      //Simulating web server
      app.get('/uploadImage', function (req, res) {
          res.writeHead(200, {'content-type': 'text/html'});
          res.end(
              '<form action="/uploadImage" enctype="multipart/form-data" method="post">'+
              '<input type="text" name="title"><br>'+
              '<input type="file" name="upload" multiple="multiple"><br>'+
              '<input type="submit" value="Upload">'+
              '</form>'
          );
      })
  
      //This routes matters
      app.post('/uploadImage', function (req, res) {
  
          // parse a file upload
          var form = new multiparty.Form();
  
          //After your request body is parsed with multipart/form encoding
          //You can access to the files and the fields in that form
          //You may upload it to another image service
          form.parse(req, function (err, fields, files) {
            res.writeHead(200, {'content-type': 'text/plain'});
            res.write('received upload:\n\n');
  
            //The property that matter inside files object it's path
            //With that, you can write it in your server file system (fs) 
            //or data base or cloud service
            console.log('files received', files);
            console.log('fields received', fields);
            res.end(util.inspect({fields: fields, files: files}));
          });
  
      })
  
      app.listen(3000, function() {
        console.log('listening');
      });
  

  确保安装所有依赖项 npm install express multiparty
