NodeJS:如何记录所有传入mongodb的服务器请求？

npm install express mongoose morgan

const express = require('express');
const mongoose = require('mongoose');
const morgan = require('morgan');
const app = express();

mongoose.connect('mongodb://localhost/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => console.log('Connected to MongoDB'))
  .catch(err => console.error('Failed to connect to MongoDB', err));

const requestLogSchema = new mongoose.Schema({
  method: String,
  url: String,
  timestamp: { type: Date, default: Date.now }
});

const RequestLog = mongoose.model('RequestLog', requestLogSchema);

app.use(morgan('combined', {
  stream: {
    write: function (message) {
      const log = new RequestLog({
        method: message.split(' ')[0],
        url: message.split(' ')[1]
      });
      log.save();
    }
  }
}));

app.listen(3000, () => console.log('Server started on port 3000'));
