一、Cookie
通过 Set-Cookie 设置、 下次浏览器请求就会带上、 键值对，可以设置多个。
Cookie 属性
max-age 和 expires 设置过期时间
Secure 只在 https 的时候发送
HttpOnly 无法通过 document.cookie 访问
server.js 代码
const http = require(‘http‘)const fs = require(‘fs‘)http.createServer(function (request, response) { ?console.log(‘request come‘, request.url) ?if (request.url === ‘/‘) { ???const html = fs.readFileSync(‘test.html‘, ‘utf8‘) ???response.writeHead(200, { ?????‘Content-Type‘: ‘text/html‘, ?????‘Set-Cookie‘: [‘id=123; max-age=2‘, ‘abc=456;domain=test.com‘] ???}) ???response.end(html) ?}}).listen(8888)console.log(‘server listening on 8888‘)test.html 代码
<!DOCTYPE html><html lang="en"><head> ?<meta charset="UTF-8"> ?<meta name="viewport" content="width=device-width, initial-scale=1.0"> ?<meta http-equiv="X-UA-Compatible" content="ie=edge"> ?<title>Document</title></head><body> ?<div>Content</div></body><script> ?console.log(document.cookie)</script></html>

二、 HTTP 长连接
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‘) ?const img = fs.readFileSync(‘test.jpg‘) ?if (request.url === ‘/‘) { ???response.writeHead(200, { ?????‘Content-Type‘: ‘text/html‘, ???}) ???response.end(html) ?} else { ???response.writeHead(200, { ?????‘Content-Type‘: ‘image/jpg‘, ?????‘Connection‘: ‘keep-alive‘ // or close ???}) ???response.end(img) ?}}).listen(8888)console.log(‘server listening on 8888‘)test.html
<!DOCTYPE html><html lang="en"><head> ?<meta charset="UTF-8"> ?<meta name="viewport" content="width=device-width, initial-scale=1.0"> ?<meta http-equiv="X-UA-Compatible" content="ie=edge"> ?<title>Document</title></head><body> ?<img src="/test1.jpg" alt=""> ?<img src="/test2.jpg" alt=""> ?<img src="/test3.jpg" alt=""> ?<img src="/test4.jpg" alt=""> ?<img src="/test5.jpg" alt=""> ?<img src="/test6.jpg" alt=""> ?<img src="/test7.jpg" alt=""> ?<img src="/test11.jpg" alt=""> ?<img src="/test12.jpg" alt=""> ?<img src="/test13.jpg" alt=""> ?<img src="/test14.jpg" alt=""> ?<img src="/test15.jpg" alt=""> ?<img src="/test16.jpg" alt=""> ?<img src="/test17.jpg" alt=""> ?<img src="/test111.jpg" alt=""> ?<img src="/test112.jpg" alt=""> ?<img src="/test113.jpg" alt=""> ?<img src="/test114.jpg" alt=""> ?<img src="/test115.jpg" alt=""> ?<img src="/test116.jpg" alt=""> ?<img src="/test117.jpg" alt=""></body></html>
test.jpg
请求运行结果：
