Post使用express js和mongodb插入多个数据

npm install express mongodb

const express = require('express');
const MongoClient = require('mongodb').MongoClient;
const bodyParser = require('body-parser');

const app = express();
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

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

MongoClient.connect(url, { useNewUrlParser: true }, (err, client) => {
  if (err) throw err;
  console.log('Connected to MongoDB');

  const db = client.db(dbName);

  // 在这里执行插入多个数据的操作
});

const collection = db.collection('users');

app.post('/users', (req, res) => {
  const users = req.body.users; // 从请求体中获取要插入的多个用户数据

  collection.insertMany(users, (err, result) => {
    if (err) throw err;
    console.log(`${result.insertedCount} users inserted`);

    res.send('Users inserted');
  });
});

const port = 3000;

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