路由模块化

1，模块化方式封装路由

Route.js

const staticWeb = require('./web')

const app={
    static:function(req,res,staticPath){
        //创建静态Web服务
        staticWeb(req, res, './static')
    },
    index:function(req,res){
        res.writeHead(200, { 'Content-Type': 'text/html;charset="utf-8"' });
        res.end("<h3>Index</h3>");
    },
    login:function(req,res){
        res.writeHead(200, { 'Content-Type': 'text/html;charset="utf-8"' });
        res.end("<h3>Login</h3>");
    },
    doLogin:function(req,res){
        res.writeHead(200, { 'Content-Type': 'text/html;charset="utf-8"' });
        res.end("<h3>doLogin</h3>");
    },
    register:function(req,res){
        req.writeHead(200, { 'Content-Type': 'text/html;charset="utf-8"' });
        res.end("<h3>register</h3>");
    },
    error:function(req,res){
        res.writeHead(200, { 'Content-Type': 'text/html;charset="utf-8"' });
        res.end("<h3>error</h3>");
    }
}
module.exports=app;

2，调用路由模块：

app.js

const http = require('http');
const url = require('url')
const Route = require('./Router');

http.createServer(function (request, response) {
    Route.static(request,response,'./static')
    let pathname = url.parse(request.url).pathname //'/login'
    if (pathname == '/') {
       Route.index(request,response)
    }
    else if(pathname=='/login'){
       Route.login(request,response)
    }
    else if(pathname=='/register'){
       Route.register(request,response)
    }
    else{
       Route.error(request,response)
    }
}).listen(8081);

console.log('Server running at http://127.0.0.1:8081/');
