服务器代码：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."); if(pathname=='/start'){//登录方法使用 request.setEncoding("utf8"); //监听器 request.addListener("data", function(postDataChunk) { console.log("获取所有的数据："+postDataChunk); postData += postDataChunk; console.log('账号是：'+postData.split('&')[0].split('=')[1]+' 密码是： '+postData.split('&')[1].split('=')[1]); }); request.addListener("end", function() { route(handle, pathname, response, postData); }); }else{//非登录方法使用 route(handle, pathname, response, request); } } http.createServer(onRequest).listen(8888); console.log("Server has started."); } exports.start = start;
路由代码：router.js
function route(handle, pathname, response, request) { console.log("About to route a request for " + pathname); if (typeof handle[pathname] === 'function') { handle[pathname](response, request); } else { console.log("No request handler found for " + pathname); response.writeHead(404, {"Content-Type": "text/html"}); response.write("404 Not found"); response.end(); } } exports.route = route;
访问的路径代码：index.js
var server = require("./server"); var router = require("./router"); var requestHandlers = require("./requestHandlers"); var handle = {} handle["/"] = requestHandlers.login; handle["/login"] = requestHandlers.login; handle["/start"] = requestHandlers.start; handle["/upload"] = requestHandlers.upload; handle["/show"] = requestHandlers.show;server.start(router.route, handle);
运行方法代码：requestHandlers.js
var querystring = require("querystring"); var fs = require("fs");//获取文件上传模块var formidable = require("formidable"); //登陆页面function login(response,postData) { console.log("Request handler 'login' was called."); var body = '<html>'+ '<head>'+ '<meta http-equiv="Content-Type" content="text/html; '+ 'charset=UTF-8" />'+ '</head>'+ '<body>'+ '<form action="/start" method="post">'+ '账号：<input type="text" name="username" /><br /><br />'+ '密码：<input type="password" name="password" /><br /><br />'+ '<input type="submit" value="登录" />'+ '</form>'+ '</body>'+ '</html>'; response.writeHead(200, {"Content-Type": "text/html"}); response.write(body); response.end(); } //上传页面function start(response, postData) { var body2 = '<html>'+ '<head>'+ '<meta http-equiv="Content-Type" content="text/html; '+ 'charset=UTF-8" />'+ '</head>'+ '<body>'+ '你好'+postData.split('&')[0].split('=')[1]+'，欢迎登陆<br />账号是： '+postData.split('&')[0].split('=')[1]+' 密码是： '+postData.split('&')[1].split('=')[1]+'<br />'+ '<form action="/upload" enctype="multipart/form-data" method="post">'+ '<input type="file" name="upload" multiple="multiple">'+ '<input type="submit" value="上传图片" />'+ '</form>'+ '</body>'+ '</html>'; console.log("Request handler 'upload' was called."); response.writeHead(200, {"Content-Type": "text/html"}); response.write(body2); response.end(); } //上传方法function upload(response, request) { console.log("Request handler 'upload' was called."); var form = new formidable.IncomingForm(); console.log("about to parse"); console.log("图片详细信息："+form); form.parse(request, function(error, fields, files) { console.log("parsing done"); //修改图片名称 fs.renameSync(files.upload.path, "/tmp/test.jpg"); response.writeHead(200, {"Content-Type": "text/html"}); //显示图片名称 response.write("received image:<br/>"); //显示图片 response.write("<img src='/show' style='width:500px;height:300px;'/>"); response.end(); }); } //展示方法function show(response) { console.log("Request handler 'show' was called."); //寻找文件 fs.readFile("/tmp/test.jpg", "binary", function(error, file) { if(error) { response.writeHead(500, {"Content-Type": "text/plain"}); response.write(error + "\n"); response.end(); } else { //规定文件后缀 response.writeHead(200, {"Content-Type": "image/jpg"}); response.write(file, "binary"); response.end(); } }); } exports.login = login; exports.start = start; exports.upload = upload;exports.show = show;
这些文件必须放在node.js的安装目录下
不要忘记在C盘创建文件夹：tmp。
