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:
•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
rush:js;">
node -v
npm -v
如果得到了版本号则表示nodejs安装完成
•在命令行中执行
rush:js;">
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
rush:js;">
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
rush: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
rush: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','
404
file or dir :' + pathname + '
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.html resolve(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,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),stat) { if (err) { console.error(err); resolve(''); } else if (stat.isFile()) { resolve(``); } else if (stat.isDirectory()) { resolve(``); } else { resolve(''); } }) })); }); Promise.all(pmlist).then(function (linkList) { var links = '- ';
links += '';
links += linkList.join('');
links += '
404
file or dir :' + pathname + '
not found'); } }).catch(function (err) { resWrite(response,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,data) { if (err) { resWrite(response,err.toString()); } else { var ext = path.extname(realPath).toLocaleLowerCase(); ext = (ext ? ext.slice(1) : 'unkNown'); resWrite(response,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
