nodejs文件服务器

本文尝试使用nodejs搭建一个文件服务器。
首先在官方下载node环境并安装：https://nodejs.org/en/download/
安装后node被加入到系统环境变量中。
>node --version
>v12.14.1

const http = require("http");
const Path = require("path");
const fs = require("fs");

var server = http.createServer(function(req, res) {
let currUrl = decodeURIComponent(req.url);
const fileName = Path.resolve(__dirname, "../" + currUrl);
const extName = Path.extname(fileName).substr(1);

    if (fs.existsSync(fileName)) { //判断本地文件是否存在
        var mineTypeMap = {
            html: 'text/html;charset=utf-8',
            htm: 'text/html;charset=utf-8',
            xml: "text/xml;charset=utf-8",
            png: "image/png",
            jpg: "image/jpeg",
            jpeg: "image/jpeg",
            gif: "image/gif",
            css: "text/css;charset=utf-8",
            txt: "text/plain;charset=utf-8",
            mp3: "audio/mpeg",
            mp4: "video/mp4",
            ico: "image/x-icon",
            tif: "image/tiff",
            svg: "image/svg+xml",
            zip: "application/zip",
            ttf: "font/ttf",
            woff: "font/woff",
            woff2: "font/woff2",
        }
        if (mineTypeMap[extName]) {
            res.setHeader('Content-Type', mineTypeMap[extName]);
        }
        var stream = fs.createReadStream(fileName);
        stream.pipe(res);
    }
})
server.listen(8001, function(){
    console.log("http server is running on port 8001!");
});

文件目录：

运行服务：node index.js

打开chrome浏览器：输入http://127.0.0.1:8001/demo/Simple3DEditor/index.html
