express框架封装前戏

//var route = require(‘http-route‘);
var url = require(‘url‘);
//var app = new route();
var G = {};
var app = function(req,res)
{
    var myurl = url.parse(req.url);
    var pathname = myurl.pathname;
//为了迎合解析后的路径带有‘/‘的情形，索性给参数加上‘/‘
    if(!pathname.endsWith(‘/‘))
    {
        pathname=pathname+"/";
    }
    if(G[pathname])
    {
        G[pathname](req,res);
    }
};

app.get=function(string,callback)
{

　 if (!string.endsWith("/")) {

string = string + "/";
    }
    if(!string.startsWith("/"))
    {
        string = "/"+string;
    }
    G[string]=callback;

app.get(‘login‘,function (req,res) {
    console.log("login"+req);

var app = require(‘./aexpressclass‘);
var http = require(‘http‘);
http.createServer(app).listen(3000);
