Express -如何在multer中使用sharp？

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

const app = express();
const upload = multer({ dest: 'uploads/' });

app.post('/upload', upload.single('image'), (req, res) => {
  // 使用sharp对上传的图片进行处理
  sharp(req.file.path)
    .resize(200, 200) // 缩放图片为200x200大小
    .toFile('uploads/resized_' + req.file.filename, (err, info) => {
      if (err) {
        // 处理出错
        res.status(500).send('Error occurred while processing the image');
      } else {
        // 处理成功
        res.send('Image uploaded and resized');
      }
    });
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
