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>
