判断传入路径是文件还是文件夹

//showFile -src
let argv = process.argv[2].slice(1);
const path = require('path');
const fs = require('fs');
//__dirname:当前所在js文件的绝对路径 
//process.cwd()：小黑板打开的绝对路径
let url = path.join(process.cwd(),argv);  //拼接路径
function read(url){
    // console.log(__dirname);
    // console.log("process",process.cwd())
    if(fs.existsSync(url)){
        //1.先读取目录
        letlist = fs.readdirSync(url); //[css,index.html]
        list.forEach(file=> {
            letcurUrl =path.join(url,file);
            //2.判断当前路径是文件还是文件夹
            if(fs.statSync(curUrl).isDirectory()){
                console.log(file)
                //是文件夹
                read(curUrl)
             }else{
                //是文件
                console.log(file)
             }
         })
 }else{
        console.log("当前路径不合法")
     }
}
read(url)
