如何使用multer将数组文件保存到mongoDB数据库中？

npm install multer mongoose

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

const storage = multer.diskStorage({
  destination: function (req, file, cb) {
    cb(null, 'uploads/') // 指定文件存储的路径
  },
  filename: function (req, file, cb) {
    cb(null, file.originalname) // 使用原始文件名作为文件名
  }
});

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

const fileSchema = new mongoose.Schema({
  filename: String,
  path: String
});

const File = mongoose.model('File', fileSchema);

app.post('/upload', upload.array('files'), function (req, res, next) {
  const files = req.files;

  // 将文件信息保存到MongoDB数据库中
  files.forEach(function (file) {
    const newFile = new File({
      filename: file.originalname,
      path: file.path
    });

    newFile.save(function (err) {
      if (err) {
        console.log(err);
      }
    });
  });

  res.send('文件上传成功！');
});
