Node.js 使用递归实现遍历文件夹中所有文件

var fs = require('fs');
var path = require('path');

//解析需要遍历的文件夹，我这以E盘根目录为例
var filePath = path.resolve('E:');

//调用文件遍历方法
fileDisplay(filePath);

/
  文件遍历方法
  @param filePath 需要遍历的文件路径
 /
function fileDisplay(filePath){
  //根据文件路径读取文件，返回文件列表
  fs.readdir(filePath,function(err,files){
    if(err){
      console.warn(err)
    }else{
      //遍历读取到的文件列表
      files.forEach(function(filename){
        //获取当前文件的绝对路径
        var filedir = path.join(filePath,filename);
        //根据文件路径获取文件信息，返回一个fs.Stats对象
        fs.stat(filedir,function(eror,stats){
          if(eror){
            console.warn('获取文件stats失败');
          }else{
            var isFile = stats.isFile();//是文件
            var isDir = stats.isDirectory();//是文件夹
            if(isFile){
              console.log(filedir);
            }
            if(isDir){
              fileDisplay(filedir);//递归，如果是文件夹，就继续遍历该文件夹狼蚁网站SEO优化的文件
            }
          }
        })
      });
    }
  });
}
