Node4-2静态资源服务器实战_实现获取文件路径

module.exports={
    root:process.cwd(),
    hostname:‘127.0.0.1‘,
    port:9527
}

const http = require(‘http‘);
const chalk = require(‘chalk‘)
const  path = require(‘path‘)
const fs =require(‘fs‘)
const conf = require(‘./config/defaultConfig.js‘);
const server = http.createServer((req,res)=>{
    const url = req.url;
    //拿到文件路径
    const filePath = path.join(conf.root,req.url)
    // 判断是一个文件夹还是一个文件
    fs.stat(filePath,(err,stats)=>{
        if(err){
            res.statusCode = 404
            res.setHeader(‘content-Type‘,‘text/plain‘)
            res.end(`${filePath} is not a directory or file`)
            return 
        }

        if(stats.isFile()){
            res.statusCode = 200
            res.setHeader(‘content-Type‘,‘text/plain‘)
            fs.createReadStream(filePath).pipe(res);
            // fs.readFile(filePath,(err,data)=>{

server.listen(conf.port,conf.hostname,()=>{
