示例代码
index.js
var server = require("./server");var router=require("./router");var requestHandlers=require("./requestHandlers"); var handle = {}handle["/"] = requestHandlers.start;handle["/start"] = requestHandlers.start;handle["/upload"] = requestHandlers.upload; server.start(router.route,handle);
server.js
var http = require("http");var url=require("url"); function start(route,handle) { function onRequest(request, response) { var postData=""; 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); }); //route(handle,pathname,response); //response.writeHead(200, {"Content-Type": "text/plain"}); //response.write("this is a demo"); //response.end(); } http.createServer(onRequest).listen(5656,'127.0.0.1'); console.log("Server has started. localhost:5656");} exports.start = start;
router.js
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 found for"+pathname); response.writeHead(404, {"Content-Type": "text/plain"}); response.write("404 Not found"); response.end(); }}exports.route=route;
requestHandlers.js
//var querystring = require("querystring"); 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="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/plain"}); response.write("You've sent: " + postData); response.end();} exports.start = start;exports.upload = upload;
运行:node mynode/index
