使用mongoose在动态路由下向mongodb插入新数据

npm install mongoose

const mongoose = require('mongoose');

const dataSchema = new mongoose.Schema({
  // 定义数据字段和类型
  field1: String,
  field2: Number,
  // ...
});

const Data = mongoose.model('Data', dataSchema);

app.post('/dynamic-route/:id', (req, res) => {
  const newData = new Data({
    field1: req.body.field1,
    field2: req.body.field2,
    // ...
  });

mongoose.connect('mongodb://localhost:27017/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => {
    console.log('Connected to MongoDB');
    // 在连接成功后，执行保存数据的操作
    newData.save()
      .then(() => {
        console.log('Data saved successfully');
        res.send('Data saved successfully');
      })
      .catch((error) => {
        console.error('Error saving data:', error);
        res.status(500).send('Error saving data');
      })
      .finally(() => {
        // 关闭数据库连接
        mongoose.connection.close();
      });
  })
  .catch((error) => {
    console.error('Error connecting to MongoDB:', error);
    res.status(500).send('Error connecting to MongoDB');
  });
