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：
