node.js遍历目录的方法示例

const fs = require('fs');
const path=require('path');
function travel(dir,callback){
 fs.readdirSync(dir).forEach((file)=>{
 var pathname=path.join(dir,file)
 if(fs.statSync(pathname).isDirectory()){
 travel(pathname,callback)
 }else{
 callback(pathname)
 }
 })
}
travel('F:/HTML/Node/test',function(pathname){
 console.log(pathname)
})

const fs = require('fs');
const path=require('path');
function travel(dir,callback){
 fs.readdir(dir,(err,files)=>{
 if(err){
 console.log(err)
 }else{
 files.forEach((file)=>{
 var pathname=path.join(dir,file)
 fs.stat(pathname,(err,stats)=>{
 if(err){
 console.log(err)
 }else if(stats.isDirectory()){
 travel(pathname,callback)
 }else{
 callback(pathname)
 }
 })
 })
 }
 })
}
travel('F:/HTML/Node/test',function(pathname){
 console.log(pathname)
})
