An MVC-based server written by Nodejs

At present, the implementation of static file download, based on the address to navigate to the controller corresponding controller method, but the View template feature is not yet implemented.

Server code (HTTPSERVER.JS):

varHTTP = require ("http"), URL= Require ("url"), Path= Require ("path"), FS= Require ("FS"), getContentType=function(type) {varType=type.indexof (".") ===0? TYPE.SUBSTR (1): type, Deftype= "Application/octet-stream", Types={html:"Text/html", JS:"Text/javascript", CSS:"Text/css", GIF:"Image/gif", jpg:"Image/jpeg", PNG:"Image/png",            }; return typeof(Types[type])! = "undefined"?Types[type]: Deftype; };http.createserver (function(req, res) {varPathname=Url.parse (req.url). Pathname; if(pathname== "/") {Pathname+ = "Index.html"; } Pathname=__dirname+pathname;    Console.log (Req.url); if(Req.url.match (/^\/controller\//) | | req.url.match (/^\/data\//)) {//prohibit access to directoriesRes.writehead (404, {"Content-type": "Text/html"}); }Else if(Req.url.match (/^\/\w+\/\w+ (\?. *)?$/)){//controller Output        varu=Url.parse (Req.url), CA=U.PATHNAME.SUBSTR (1). Split ("/"), C=ca[0],a=ca[1], CPath=__dirname + "/controller/" +c+ ". js", Controller; if(Fs.existssync (CPath)) {Res.writehead ($, {"Content-type": getContentType ("HTML")}); Controller=require (CPath); if(typeof(Controller[a])! = "undefined") {Controller[a] (res,u); }            //Delete Require.cache[cpath];//Whether to empty the script cache}Else{Res.writehead ($, {"Content-type": getContentType ("HTML")}); Res.end (Path+ "Not exists!"); }    }Else if(Fs.existssync (pathname)) {//static file OutputRes.writehead ($, {"Content-type"): getContentType (path.extname (pathname))}); Fs.readfile (Pathname,function(err, data) {res.end (data);    }); }Else{Res.writehead (404, {                "Content-type": getContentType ("HTML")        }); Res.end ("); }}). Listen (8080, "127.0.0.1"); Console.log ("Server running at http://127.0.0.1:8080/");

Controller code (CONTROLLER/PROJECT.JS):

varTm=1, MySQL=require ("MySQL"), Conn=mysql.createconnection ({host:' 127.0.0.1 ', User:' Root ', Password:' 123456 ', Database:' DBName ', Port:3306}); Conn.connect ();varproject={show:function(res,url) {varparas={},tb= "User";        Console.log (Url.query); if(typeof(url.query) = = "string"){            varPs=url.query.split ("&"), PSS;  for(varKinchPS) {PSS=ps[k].split ("="); paras[pss[0]]=pss[1]; }} res.write (tm+ +) + "<br/>"); Conn.query (' SELECT * from prefx_ ' + (typeof(PARAS.TB)! = "undefined"? PARAS.TB:TB) + ' limit 0,3 ',             function(Err, results, fields) {varField= "", str= "", fds=[]; if(results) { for(varKinchFields ) {Fds.push (fields[k][' Name ']); }                     for(vari = 0; i < results.length; i++) {str="";  for(varKinchFDS) {STR+=results[i][fds[k]]+ "\ T"; } res.write (str+ "<br/>"); }} res.end ("<br/>" + (NewDate ()). GetTime ());    }        ); }}module.exports=project;

The site directory structure is as follows:

For example, Access: Http://127.0.0.1:8080/project/show, then access the Show method in the project controller
