nodejs 递归拷贝、读取目录下所有文件和目录

var fs=require('fs');
var copy=function(src,dst){
 let paths = fs.readdirSync(src); //同步读取当前目录
 paths.forEach(function(path){
 var _src=src+'/'+path;
 var _dst=dst+'/'+path;
 fs.stat(_src,function(err,stats){ //stats 该对象 包含文件属性
 if(err)throw err;
 if(stats.isFile()){ //如果是个文件则拷贝
 let readable=fs.createReadStream(_src);//创建读取流
 let writable=fs.createWriteStream(_dst);//创建写入流
 readable.pipe(writable);
 }else if(stats.isDirectory()){ //是目录则 递归
 checkDirectory(_src,_dst,copy);
 }
 });
 });
}
var checkDirectory=function(src,dst,callback){
 fs.access(dst, fs.constants.F_OK, (err) => {
 if(err){
 fs.mkdirSync(dst);
 callback(src,dst);
 }else{
 callback(src,dst);
 }
 });
};
const SOURCES_DIRECTORY = 'd:commonPrefab'; //源目录
checkDirectory(SOURCES_DIRECTORY,__dirname,copy);

var fs = require('fs');
var path = require('path');
var exec = require('child_process').exec;
function readFileList(dir, filesList = []) {
 const files = fs.readdirSync(dir);
 console.log(files);
 files.forEach((item, index) => {
 var fullPath = path.join(dir, item);
 const stat = fs.statSync(fullPath);
 if (stat.isDirectory()) { 
 readFileList(path.join(dir, item), filesList); //递归读取文件
 } else { 
 filesList.push(fullPath); 
 } 
 });
 return filesList;
}
var filesList = [];
readFileList(__dirname,filesList);
console.log(filesList);
