路由

我们要为路由提供请求的URL和其他需要的GET及POST参数，随后路由需要根据这些数据来执行相应的代码。

const http = require('http')
const url = require('url')
const server = http.createServer(function (req, res) {
  const pathname = url.parse(req.url).pathname
  if (pathname == '/') {
    res.end('hello')
  } else if (pathname == '/getList') {
    res.writeHead(200, { 'Content-Type': 'application/json; charset=utf-8' })
    res.write(JSON.stringify({ recrods: [{ name: 'fyx' }] }))
    res.end()
  } else {
    res.writeHead(200, { 'Content-Type': 'text/plain; charset=utf-8' })
    res.end('默认值')
  }
})
server.listen('3030', function () {
  console.log('服务器正在监听3030端口')
})

整理:

index.js

const http = require('http')
const url = require('url')
const router = require('./router')
const server = http.createServer(function (req, res) {
  const pathname = url.parse(req.url).pathname
  router(pathname, res)
})
server.listen('3030', function () {
  console.log('服务器正在监听3030端口')
})

router.js

module.exports = (pathname, res) => {
  res.writeHead(200, { 'Content-Type': 'application/json; charset=utf-8' })
  if (pathname == '/') {
    res.end('hello')
  } else if (pathname == '/getList') {
    res.write(JSON.stringify({ recrods: [{ name: 'fyx' }] }))
    res.end()
  } else {
    res.end('默认值')
  }
}
