requestHandlers.js

/*简但的demo POST数据，并接受数据*//*requestHandlers.js模块*/function start(response,postData){	console.log("Request handler ‘start‘ was called");		var body = ‘<html>‘ +	 ‘<head>‘+     ‘<meta http-equiv="Content-Type" content="text/html; ‘+     ‘charset=UTF-8" />‘+     ‘</head>‘+     ‘<body>‘+     ‘<form action="/upload" method="post">‘+     ‘<textarea name="text" rows="20" cols="60"></textarea>‘+     ‘<input type="submit" value="http://www.mamicode.com/Submit text" />‘+     ‘</form>‘+     ‘</body>‘+     ‘</html>‘; 		response.writeHead(200,{"Content-Type":"text/html"});	response.write(body);	response.end();	}function upload(response,postData){	console.log("Request handler ‘upload‘ was called");	response.writeHead(200,{"Content-Type":"text/html"});	response.write("you‘ve sent" + postData);	response.end();}exports.start = start;exports.upload = upload;

router.js

/*routers.js 模块*//*通过检查给定的路径对应的请求处理程序是否存在，如果存在的话直接调用相应的函数，并返回相应是字符串*/function route(handle,pathname,response,postData){	console.log("About to route a request for " + pathname);	if(typeof handle[pathname] === ‘function‘){		handle[pathname](response,postData);	}else{		console.log("No request handler for  " + pathname);			response.writeHead(404,{"Content-Type":"text/html"});			response.write("404 Not found");			response.end();	}}exports.route = route;

server.js

/*server模块*/var http = require("http");var url = require("url");function start(route, handle){	function onRequest(request, response){		var postDatahttp://www.mamicode.com/= "";		var pathname = url.parse(request.url).pathname;		console.log("Request for " + pathname + "received");				request.setEncoding("utf8");				request.addListener("data",function(postDataChunk){			postData += postDataChunk;			console.log("Received POST data chunk" + postDataChunk + ".");		});				request.addListener("end", function(){			route(handle, pathname, response, postData);		});	}	http.createServer(onRequest).listen(3000);	console.log("Server has started");}exports.start = start;

index.js　

/*index模块*/var server = require("./server");var router = require("./router"); var requestHandlers = require("./requestHandlers");  var handle = {} //区分大小写的  handle["/"] = requestHandlers.start; handle["/start"] = requestHandlers.start; handle["/upload"] = requestHandlers.upload;  server.start(router.route, handle);
