//浏览器是允许像<link>、<img>、<Script>在标签上路径加载内容时是允许跨域的，它不关心服务器是否设置了跨域的头

server.js

const http = require('http')
const fs = require('fs')

http.createServer(function (request, response) {
  console.log('request come', request.url)

  const html = fs.readFileSync('test.html', 'utf8')//读取HTML内容
  response.writeHead(200, {
    'Content-Type': 'text/html'
  })
  response.end(html)
}).listen(8888)

console.log('server listening on 8888')

server2.js

const http = require('http')

http.createServer(function (request, response) {
  console.log('request come', request.url)
  response.end('123')
}).listen(8887)

console.log('server listening on 8887')
