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)
})
