这毕竟大势所趋,了解一下无防的。
最终,对JS的要求还是有点高。。。
以后弄过一次,很快就忘了。
再来再拾起来一下。
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); }); } http.createServer(onRequest).listen(8888); console.log("server start listen at port 8888!"); } 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') { return 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"); fs = require("fs"); 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 send: " + querystring.parse(postData).text); response.end(); } function show(response, postData) { console.log("Request handler 'show' was called."); fs.readFile("GH2.png", "binary", function(error, file) { if(error) { response.writeHead(500, {"Content-Type": "text/plain"}); response.write(error + "\n"); response.end(); } else { response.writeHead(200, {"Content-Type": "image/png"}); response.write(file, "binary"); response.end(); } }); } exports.start = start; exports.upload = upload; exports.show = show;
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; handle["/show"] = requestHandlers.show; server.start(router.route, handle);
