如何在express js中使用multer上传具有多个表单输入的单个文件？

const express = require('express');
const multer = require('multer');

const app = express();

// Multer配置
const storage = multer.diskStorage({
  destination: (req, file, cb) => {
    // 指定文件保存的目录
    cb(null, 'uploads/');
  },
  filename: (req, file, cb) => {
    // 指定文件保存的名称
    cb(null, file.originalname);
  }
});

const upload = multer({ storage: storage });

app.post('/upload', upload.single('file'), (req, res) => {
  // 处理上传的文件
  console.log(req.file);
  res.send('文件上传成功！');
});

<form action="/upload" method="POST" enctype="multipart/form-data">
  <input type="file" name="file">
  <input type="text" name="name">
  <input type="submit" value="上传">
</form>
