首先先看一下文件的结构：
我想通过改变不同的路由进不同的页面，
先看这几个HTML页面：
404：
<!DOCTYPE html><html lang="en"><head> ???<meta charset="UTF-8"> ???<title>Document</title></head><body>404</body></html>
about:
<!DOCTYPE html><html lang="en"><head> ???<meta charset="UTF-8"> ???<title>Document</title></head><body>about</body></html>
home:
<!DOCTYPE html><html lang="en"><head> ???<meta charset="UTF-8"> ???<title>Document</title></head><body>home</body></html>
再看一下主要的root.js:
// 加载所需模块let http = require(‘http‘);let url = require(‘url‘);let fs = require(‘fs‘);let host = ‘127.0.0.1‘;let port = 8080;http.createServer(function(req,res){ ???let pathname = url.parse(req.url).pathname; ???console.log(‘Request for ‘ + pathname + ‘ received.‘); ???function showPaper(path,status){ ???????let content = fs.readFileSync(path); ???????res.writeHead(status, { ‘Content-Type‘: ‘text/html;charset=utf-8‘ }); ???????res.write(content); ???????res.end(); ???} ???switch(pathname){ ???????//‘首页‘ ???????case ‘/‘: ???????case ‘/home‘: ???????????showPaper(‘./rooter/home.html‘,200); ???????????break; ???????//‘about页‘ ???????case ‘/about‘: ???????????showPaper(‘./rooter/about.html‘,200); ???????????break; ???????//‘404页‘ ???????default: ???????????showPaper(‘./rooter/404.html‘,404); ???????????break; ???}}).listen(port, host);首先我们得到了路由的URL的pathname,然后通过pathname进行判断，这里是通过使用readFileSync同步读取文件内容的方法，再写到页面中的方法进行路由的转换，结果如下：
使用Node.js完成路由
