尝试在Node.js和MongoDB中通过GET请求执行搜索查询

npm install express

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

app.get('/search', (req, res) => {
  const searchTerm = req.query.term; // 获取GET请求中的搜索关键词

  // 连接MongoDB数据库
  MongoClient.connect(url, (err, client) => {
    if (err) {
      console.error('Failed to connect to MongoDB:', err);
      res.status(500).send('Failed to connect to MongoDB');
      return;
    }

    const db = client.db(dbName);
    const collection = db.collection('your-collection-name'); // 集合名称

    // 在MongoDB中执行搜索查询
    collection.find({ $text: { $search: searchTerm } }).toArray((err, result) => {
      if (err) {
        console.error('Failed to execute search query:', err);
        res.status(500).send('Failed to execute search query');
        return;
      }

      res.json(result); // 返回查询结果
      client.close(); // 关闭数据库连接
    });
  });
});

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

node app.js
