在windows上用nodejs搭建静态文件服务器的简单方法

时间：2021-05-25

在windows上用nodejs搭建一个静态文件服务器，即使你一点基础没有也能学会nodejs静态文件服务器的搭建，本文介绍的非常详细，很适合零基础入门的朋友学习。

首先安装nodejs:

•新建一个node文件夹

•下载node.exe到该文件夹

•下载npm然后解压到该文件夹

•现在node文件夹是这样的

•把该目录加入到path环境变量

•在命令行执行

node -vnpm -v

如果得到了版本号则表示nodejs安装完成

•在命令行中执行

npm config set registry https://registry.npm.taobao.org

以后安装nodejs模块 都会从淘宝的npm镜像中下载

•如果想要发布自己的模块到npm要先把npm的registry切换回来

npm config set registry https://registry.npmjs.org

接下来搭建静态文件服务器

•创建一个文件夹server,一个文件夹root,server内是服务器的js代码,root是根目录

•server文件夹里面创建js文件 index.js mime.js server.js

•index.js

var server = require('./server.js');var rootpath = 'root';var sv = server.create({port: '9587',host: '127.0.0.1',root: rootpath}); •mime.js var types = {"css": "text/css","less": "text/css","gif": "image/gif","html": "text/html","ejs": "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","default": "text/plain"};module.exports = function (ext) {return types[ext] || 'text/plain'}

•server.js

var http = require('http');var path = require('path');var fs = require('fs');var url = require("url");var mime = require('./mime.js');function getPromise(cbk) {return (new Promise(cbk));}exports.create = function (opts) {var root = opts.root;var sv = http.createServer();function request(request, response) {var pathname = decodeURIComponent(url.parse(request.url).pathname);var realPath = path.resolve(path.join(root, pathname));//请求的实际路径getPromise(function (resolve, reject) {fs.exists(realPath, function (isExists) {//判断路径是否存在isExists ? resolve() : reject();});}).catch(function () {resWrite(response, '404', 'html', '<h1>404</h1>file or dir : <h3>' + pathname + '</h3>not found');}).then(function () {return getPromise(function (resolve, reject) {fs.stat(realPath, function (err, stat) {//判断路径是文件还是文件夹if (err) {reject(err);} else {resolve(stat);}})}).then(function (stat) {if (stat.isFile()) {//路径对应的是一个文件resFile(response, realPath);} else if (stat.isDirectory()) {//路径对应的是一个文件夹var defaultIndexPath = path.resolve(realPath, 'index.html');return getPromise(function (resolve, reject) {fs.exists(defaultIndexPath, function (isExists) {if (isExists) {//如果该文件夹内有index.htmlresolve(true);} else {//该文件夹内没有index.html 则 显示该文件夹的内容列表resolve(false);}})}).then(function (isExistsIndex) {if (isExistsIndex) {resFile(response, defaultIndexPath);} else {return getPromise(function (resolve, reject) {fs.readdir(realPath, function (err, list) {if (err) {reject(err);} else {resolve(list);}})}).then(function (list) {var pmlist = list.map(function (item) {return (new Promise(function (resolve, reject) {fs.stat(path.resolve(realPath, item), function (err, stat) {if (err) {console.error(err);resolve('');} else if (stat.isFile()) {resolve(`<li class="file"><a href="${item}">${item}</a></li>`);} else if (stat.isDirectory()) {resolve(`<li class="dir"><a href="${item}/">${item}</a></li>`);} else {resolve('');}})}));});Promise.all(pmlist).then(function (linkList) {var links = '<ul>';links += '<li class="dir"><a href="../">../</a></li>';links += linkList.join('');links += '</ul>';var dirPage = `<!doctype html><html><head><meta charset="utf-8"/><style>a{color:blue;text-decoration: none;}.dir a{color:orange}</style></head><body>${links}</body></html>`;resWrite(response, '200', 'html', dirPage);});}).catch(function (err) {resWrite(response, '500', 'default', err.toString());})}})} else {//既不是文件也不是文件夹resWrite(response, '404', 'html', '<h1>404</h1>file or dir : <h3>' + pathname + '</h3>not found');}}).catch(function (err) {resWrite(response, '500', 'default', err.toString());})})}sv.on('request', request);sv.listen(opts.port, opts.host);return sv;};function resFile(response, realPath) {//输出一个文件fs.readFile(realPath, function (err, data) {if (err) {resWrite(response, '500', 'default', err.toString());} else {var ext = path.extname(realPath).toLocaleLowerCase();ext = (ext ? ext.slice(1) : 'unknown');resWrite(response, '200', ext, data);}});}function resWrite(response, statusCode, mimeKey, data) {response.writeHead(statusCode, {'Content-Type': mime(mimeKey)});response.end(data);}

•在server文件夹内按住shift按钮,鼠标右键点击文件夹内空白区域,点击在此处打开命令窗口,执行命令

node index.js
