前面的话

  本文将使用NodeJS实现较复杂应用的路由功能

 

结构

  项目结构如下

  代码如下

 

功能

【router.js】

// 加载所需模块
var http = require('http');
var url = require('url');
var fs = require('fs');

var host = '127.0.0.1';
var port = 8080;

http.createServer(function(req,res){
    var pathname = url.parse(req.url).pathname;
    console.log('Request for ' + pathname + ' received.');
        function showPaper(path,status){
            var 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('./view/home.html',200);
            break;
        //'about页'
        case '/about':
            showPaper('./view/about.html',200);   
            break;
        //'404页'
        default:
            showPaper('./view/404.html',404);
            break;                            
    }    
}).listen(port, host);

【404.html】

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
</head>
<body>
404    
</body>
</html>

【about.html】

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
</head>
<body>
about    
</body>
</html>

【home.html】

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
</head>
<body>
home    
</body>
</html>
