使用node搭建本地web服务器

let http = require("http");
let fs = require("fs");
let contentType = {
    "html":"text/html",
    "css":"text/css",
    "js":"application/x-javascript",
    "jpg":"application/x-jpg",
    "png":"application/x-png",
    "json":"application/json",
    "map":"application/map",
    "swf":"application/x-shockwave-flash"
}
http.createServer(function(req,res){
    let url = req.url==="/"?'/index.html':req.url;
    let file = __dirname + url;
    let file_content_type = url.split(".")[url.split(".").length-1];
    fs.readFile(file,function(error,data){
        if(error){
            res.writeHead('200',{
                "Content-type":`${contentType[file_content_type]};charset='utf-8'`
            });
            res.write('<h2>404页面未找到</h2>');
            res.end();
        }else{
            res.writeHead('200',{
                "Content-type":`${contentType[file_content_type]};charset='utf-8'`
            });
            res.write(data);
            res.end();   
        }
    })
}).listen("2222");
console.log("the server is listen in 127.0.0.1:2222")

Content-type类型写的还不够完整~

当然node也有一些成型的插件供你使用

anywhere   

www.npmjs.com/package/any…

npm install anywhere -g

目录下运行 anywhere 就可以了~
