node（文件上传与get、post请求处理）：
1 /* 2 * http：超文本传输协议 3 * http模块：能够搭建服务器环境（模拟的客服端环境） 4 * 5 * */ 6 7 var http = require("http"); 8 var url = require("url"); 9 var fs = require("fs"); 10 var formidable = require("formidable"); 11 var server = http.createServer(function (request,response) { 12 // console.log(request.url); 13 var urlObj = url.parse(request.url,true); 14 // console.log(urlObj); 15 // console.log(request.method); 16 // response.end("响应结束"); 17 18 if(urlObj.pathname == "/10post.html" || urlObj.pathname == "/"){ 19 //访问表单页面 20 var rs = fs.createReadStream("10post.html"); 21 rs.pipe(response); 22 // response.end();不能带end() 23 }else if(urlObj.pathname == "/post"){ 24 // console.log(urlObj); 25 // request.on("data",function(chunk){ 26 // console.log(chunk); 27 // }); 28 29 var form = new formidable.IncomingForm(); 30 form.parse(request,function (err,fields,files) { 31 // console.log(fields); 32 console.log(files); 33 console.log(files.fileup.path);//文件上传的临时路径 files.fileup.path 34 fs.createReadStream(files.fileup.path).pipe(fs.createWriteStream("./upload/" + files.fileup.name)); 35 36 }); 37 response.end(); 38 }else if(urlObj.pathname == "/ajax"){ 39 var newTime = new Date(); 40 response.end(newTime.toString()); 41 }else if(urlObj.pathname == "/req"){ 42 console.log(urlObj.query); 43 var result= ""; 44 request.on("data",function(chunk){ 45 result += chunk.toString(); 46 }); 47 request.on("end",function(err){ 48 response.end("参数是" + result); 49 }) 50 response.end("参数是" + JSON.stringify(urlObj.query)); 51 }else if(urlObj.pathname != "/favicon.ico"){ 52 //其他的所有页面 53 // ./post.css 54 console.log(urlObj.pathname); 55 fs.createReadStream("." + urlObj.pathname).pipe(response); 56 } 57 }); 58 server.listen(2333);
GET、POST请求：
