通过Node.js/Express在Mongo中找到不工作的记录_id

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

const app = express();
const url = 'mongodb://localhost:27017'; // MongoDB连接URL
const dbName = 'your-database-name'; // 数据库名称

app.get('/findNotWorkingRecord/:id', (req, res) => {
  const recordId = req.params.id; // 获取请求中的记录_id

  MongoClient.connect(url, { useNewUrlParser: true }, (err, client) => {
    if (err) {
      console.error('Failed to connect to MongoDB:', err);
      res.status(500).send('Internal Server Error');
      return;
    }

    const db = client.db(dbName); // 获取数据库实例
    const collection = db.collection('your-collection-name'); // 获取集合实例

    collection.findOne({ _id: new mongodb.ObjectID(recordId) }, (err, result) => {
      if (err) {
        console.error('Failed to find record:', err);
        res.status(500).send('Internal Server Error');
        return;
      }

      if (!result) {
        res.status(404).send('Record not found');
        return;
      }

      res.json(result); // 返回找到的记录
    });
  });
});

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