使用nodejs在mongodb中持续存储get和存储数据

const express = require('express');
const MongoClient = require('mongodb').MongoClient;
const app = express();
const port = 3000;

// MongoDB连接字符串
const url = 'mongodb://localhost:27017';
const dbName = 'mydatabase';

// 创建MongoDB客户端实例
let db;
MongoClient.connect(url, { useNewUrlParser: true, useUnifiedTopology: true }, (err, client) => {
  if (err) {
    console.error('Failed to connect to MongoDB', err);
    return;
  }
  console.log('Connected successfully to MongoDB');
  db = client.db(dbName);
});

// 简单的GET路由，用于存储数据
app.get('/storedata', (req, res) => {
  const data = { timestamp: new Date(), value: Math.random() };

  db.collection('data').insertOne(data, (err, result) => {
    if (err) {
      console.error('Failed to insert data', err);
      res.status(500).send('Internal Server Error');
      return;
    }
    console.log('Data inserted successfully', result);
    res.status(200).send('Data stored');
  });
});

app.listen(port, () => {
  console.log(`Server running on port ${port}`);
});
