如何仅使用带有节点的http来监听GET请求？ 没有快递

Question

I'm wondering how to listen to http get requests with only "require http" instead of express.

This is what I have now:

let http = require('http');
let server = http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello, World!\n');
});
server.listen(8443);
console.log('Server running on port 8443');

I want to listen to get requests, and console.log the url. and if there is any other request i want to print ("bad request").

You need to check what method was used using http: message.method and if it is not GET then send another response.

'use strict'
let http = require('http');
let server = http.createServer(function (req, res) {
  if( req.method === 'GET' ) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello, World!\n');
  } else {
    res.writeHead(405, {'Content-Type': 'text/plain'});
    res.end('Method Not Allowed\n');
  }
});
server.listen(8443);
console.log('Server running on port 8443');
