<form action="upload.php" method="post" enctype="multipart/form-data">
  <input type="file" name="image" />
  <input type="submit" value="Upload" />
</form>

const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');

// 连接到MongoDB数据库
const url = 'mongodb://localhost:27017';
const dbName = 'mydatabase';

MongoClient.connect(url, function(err, client) {
  assert.equal(null, err);
  console.log('Connected successfully to server');

  const db = client.db(dbName);

  // 获取表单提交的图像文件
  const imageFile = req.files.image;

  // 将图像数据插入到MongoDB的集合中
  const collection = db.collection('images');
  collection.insertOne({ image: imageFile.data }, function(err, result) {
    assert.equal(err, null);
    console.log('Image inserted successfully');
    client.close();
  });
