下面贴上我的代码
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, postData);
});
// route(handle, pathname, response);
}
http.createServer(onRequest).listen(8888);
console.log("Server has started.");
} // console.log(“Server has started.”); 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;
index.js
var server = require("./server"); var router = require("./router"); var requestHandlers = require("./requestHandlers");
var handler = {}; handler["/"] = requestHandlers.start; handler["/start"] = requestHandlers.start; handler["/upload"] = requestHandlers.upload; handler["/show"] = requestHandlers.show;
server.start(router.route, handler);
requestHandlers.js
var exec = require(“child_process”).exec; var querystring = require(“querystring”); var fs = require(“fs”); function start(response, postData) { console.log(“Request handler ‘start’ was called”);
var body = '<html>'+

response.write(body);
response.end();
