如何使用express fileupload分别限制图片和视频的文件大小？

npm install express express-fileupload

const express = require('express');
const fileUpload = require('express-fileupload');
const app = express();

app.use(fileUpload());

app.post('/upload', (req, res) => {
  if (!req.files || !req.files.image || !req.files.video) {
    return res.status(400).send('No files were uploaded.');
  }

  const image = req.files.image;
  const video = req.files.video;

  if (image.size > 2 * 1024 * 1024) {
    return res.status(400).send('Image file size exceeds the limit of 2MB.');
  }

  if (video.size > 10 * 1024 * 1024) {
    return res.status(400).send('Video file size exceeds the limit of 10MB.');
  }

  // 文件大小符合要求，可以进行后续操作
  // ...

  res.send('Files uploaded successfully.');
});
