请求路径

const fs = require('fs');
const http = require('http');
const path = require('path');

res.setHeader('Content-type','text/html;charset = utf-8');
const static = 'public';
//获取请求路径
let pathname = url.parse(req.url).pathname;
//判断访问的是不是根路径
if(pathname === '/'){
    pathname = 'index.html';
}
//区分是不是静态路径
if(path.extname(pathname)){
   //是静态资源
   if(fs.existsSync(path.join(static,pathname))){
       res.end(fs.readFileSync(path.join(static,pathname)));
   }else{
       res.end(fs.readFileSync('publice/404.html'));
   }
}else{
   //是接口
    if(pathname === '/12345678'){
        res.end('hhhhh');
    }
    res.end('api 找不到');
}
