升级一下上一篇的功能
首先还是配置：config.js
module.exports = {host: 'http://127.0.0.1', //主机名port: 3000, //服务器端口号documentRoot: 'E:/webdev', //根目录directoryBrowse: true, //是否开启目录浏览功能directoryIndex: [ //目录默认访问页'index.html','index.htm','deflaut.html'],charset: 'utf-8',mineType: {image: {gif: 'image/gif',jpeg: 'image/jpeg',jpg: 'image/jpeg',png: 'image/png',},text: {css: 'text/css',htm: 'text/html',html: 'text/html',js: 'application/x-javascript',json: 'application/json',pdf: 'application/pdf',},other: 'text/plain'} }
接着是服务器代码：index.js
const http = require('http')
const fs = require('fs')
const path = require('path')
const tpl = require('art-template')
const config = require('./config')
const server = http.createServer()
const documentRoot = config.documentRootserver.on('request', function (req, res) {let url = req.urlconsole.log(url)let tmp = documentRoot + urllet exist = fs.existsSync(tmp)if (exist) {let stats1 = fs.statSync(tmp)if (stats1.isDirectory()) {for (let key in config.directoryIndex) {let file = tmp + '/' + config.directoryIndex[key]console.log(`${config.host}:${config.port + url + config.directoryIndex[key]}`);if (fs.existsSync(file)) {res.writeHead(302, {'Location': `${config.host}:${config.port + url + config.directoryIndex[key]}`})res.end()return}}if (!config.directoryBrowse) {//没有开放目录浏览权限res.writeHead(403, {"Content-Type": "text/html"});res.end('<h2>403 forbidden!!</h2>')return}fs.readFile('./template-apache.html', function (err, data) {if (err) {return res.end('404 Not Found.')}let prevDisplay = 'block'if (url == '/') {prevDisplay = 'none'}fs.readdir(tmp, function (err, files) {if (err) {return res.end('Can not find www dir.')}let fileObjArr = []for(key in files){fileObjArr[key] = {}fileObjArr[key].name = files[key]fileObjArr[key].type = 'file'fileObjArr[key].separate = ''let stats = fs.statSync(tmp + files[key])if (stats.isDirectory()) {fileObjArr[key].type = 'dir'fileObjArr[key].separate = '/'}fileObjArr[key].href = `${config.host}:${config.port + url + files[key] + fileObjArr[key].separate}`}let parentPath = url.substring(0, url.substr(0, url.length - 1).lastIndexOf('/') + 1)let htmlStr = tpl.render(data.toString(), {title: 'Index Of' + url,files: fileObjArr,prevDisplay,parentPath})res.end(htmlStr)})})} else {//渲染文件fs.readFile(tmp, function (err, data) {if (err) {res.end()}let ext = path.extname(tmp).substring(1)if (ext in config.mineType.text) {res.setHeader('Content-Type', `${config.mineType.text[ext]}; charset=${config.charset}`)} else if (ext in config.mineType.image) {res.setHeader('Content-Type', `${config.mineType.text[ext]}`)} else {res.setHeader('Content-Type', `${config.mineType.other}; charset=${config.charset}`)}res.end(data)})}} else {res.end()}
})
server.listen(config.port, function () {console.log(`server running in: ${config.host}:${config.port}`)const cp = require('child_process')cp.exec(`start ${config.host}:${config.port}`) //自动打开浏览器
}) 最后是模板：template-apache.html
<html> <head><meta charset="utf-8"><style>h1 {border-bottom: 1px solid #c0c0c0;margin-bottom: 10px;padding-bottom: 10px;white-space: nowrap;}table {border-collapse: collapse;}a.icon {-webkit-padding-start: 1.5em;text-decoration: none;}a.icon:hover {text-decoration: underline;}a.file {background: url("data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAIAAACQkWg2AAAABnRSTlMAAAAAAABupgeRAAABHUlEQVR42o2RMW7DIBiF3498iHRJD5JKHurL+CRVBp+i2T16tTynF2gO0KSb5ZrBBl4HHDBuK/WXACH4eO9/CAAAbdvijzLGNE1TVZXfZuHg6XCAQESAZXbOKaXO57eiKG6ft9PrKQIkCQqFoIiQFBGlFIB5nvM8t9aOX2Nd18oDzjnPgCDpn/BH4zh2XZdlWVmWiUK4IgCBoFMUz9eP6zRN75cLgEQhcmTQIbl72O0f9865qLAAsURAAgKBJKEtgLXWvyjLuFsThCSstb8rBCaAQhDYWgIZ7myM+TUBjDHrHlZcbMYYk34cN0YSLcgS+wL0fe9TXDMbY33fR2AYBvyQ8L0Gk8MwREBrTfKe4TpTzwhArXWi8HI84h/1DfwI5mhxJamFAAAAAElFTkSuQmCC ") left top no-repeat;}a.dir {background: url("data:image/png;base64,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 ") left top no-repeat;}a.up {background: url("data:image/png;base64,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 ") left top no-repeat;}#parentDirLinkBox {margin-bottom: 10px;padding-bottom: 10px;}</style><title id="title">{{ title }}</title> </head><body> <h1 id="header">{{ title }}</h1> <div id="parentDirLinkBox" style="display:{{ prevDisplay }}"><a id="parentDirLink" class="icon up" href="{{ parentPath }}"><span id="parentDirText">[上级目录]</span></a> </div> <table>{{each files}}<tr><td data-value="apple/"><a class="icon {{$value.type}}" href="{{$value.href}}">{{$value.name}}{{ $value.separate}}</a></td></tr>{{/each}} </table> </body></html>
