nodejs輕量服務器后端

搭建思路

server.js主函數 + mine.js配置文件 + index.html 測試網頁

目錄結構

__./|__ test1|__ index.html|__ mine.js|__ server.js

server.js文件

var PORT = 8080; //端口 var DIR = 'test1'; //用于存放html的目錄var http = require('http'); var url=require('url'); var fs=require('fs'); var mine=require('./mine').types; var path=require('path');var server = http.createServer(function (request, response) {var pathname = url.parse(request.url).pathname;var realPath = path.join(DIR, pathname);//console.log(realPath);var ext = path.extname(realPath);ext = ext ? ext.slice(1) : 'unknown';fs.exists(realPath, function (exists) {if (!exists) {response.writeHead(404, {'Content-Type': 'text/plain'});response.write("This request URL " + pathname + " was not found on this server.");response.end();} else {fs.readFile(realPath, "binary", function (err, file) {if (err) {response.writeHead(500, {'Content-Type': 'text/plain'});response.end(err);} else {var contentType = mine[ext] || "text/plain";response.writeHead(200, {'Content-Type': contentType});response.write(file, "binary");response.end();}});}}); });server.listen(PORT); console.log("Server runing at port: " + PORT + ".");

mine.js

exports.types = {"css": "text/css","gif": "image/gif","html": "text/html","ico": "image/x-icon","jpeg": "image/jpeg","jpg": "image/jpeg","js": "text/javascript","json": "application/json","pdf": "application/pdf","png": "image/png","svg": "image/svg+xml","swf": "application/x-shockwave-flash","tiff": "image/tiff","txt": "text/plain","wav": "audio/x-wav","wma": "audio/x-ms-wma","wmv": "video/x-ms-wmv","xml": "text/xml" };

測試網頁自備index.html

<h1>hello world</h1>

執行腳本

node server.js
