Node.js静态服务器

一 目录结构

二 index.ts

//index.ts
import * as http from 'http';
import {IncomingMessage, ServerResponse} from 'http';
import * as fs from 'fs';
import * as p from 'path';
import * as url from 'url';

const server = http.createServer();
const publicDir=p.resolve(__dirname,'public');
const cacheAge=3600*24*365;
server.on('request', (request: IncomingMessage, response:ServerResponse) => {
    const {method,url: path,headers}=request;
    //静态服务器不能post
    if(method!='GET'){
        response.statusCode=405;
        response.end("fake response");
        return;
    }

    const {pathname}=url.parse(path);
    let filename=pathname.substring(1);
    if(filename===''){
        filename='a.html';//首页
    }
    fs.readFile(p.resolve(publicDir,filename),(err,data)=>{
        if(err){
            fs.readFile(p.resolve(publicDir,'404.html'),(err1,data)=>{
                response.statusCode=404;
                response.end(data)
            })
        }else{
            //设置缓存
            response.setHeader('Cache-Control',`public,max-age=${cacheAge}`)
            response.end(data);
        }
    })

});

server.listen(8888);
