NodeJS遍历文件生产文件列表功能示例

var fs = require("fs");
//path模块，可以生产相对和绝对路径
var path = require("path");
//配置远程路径
var remotePath = "/resource/fd/promote/201507/qixi/";
//获取当前目录绝对路径，这里resolve()不传入参数
var filePath = path.resolve();
//读取文件存储数组
var fileArr = [];
//读取文件目录
fs.readdir(filePath,function(err,files){
  if(err){
    console.log(err);
    return;
  }
  var count = files.length;
  //console.log(files);
  var results = {};
  files.forEach(function(filename){
    //filePath "/" filename不能用/直接连接，Unix系统是”/“，Windows系统是”\“
    fs.stat(path.join(filePath,filename),function(err, stats){
      if (err) throw err;
      //文件
      if(stats.isFile()){
        if(getdir(filename) == 'html'){
          var newUrl=remotePath filename;
          fileArr.push(newUrl);
          writeFile(fileArr);
        }
        // (getdir(filename) == 'html')&&(fileArr.push(filename);writeFile(newUrl));
      //  console.log("%s is file", filename);
      }else if(stats.isDirectory()){
        // console.log("%s is a directory文件目录", filename);
　　　　　　　　　//返回指定文件名的扩展名称 
　　　　　　　 　//console.log(path.extname("pp/index.html"));
         if(filename == 'css' || filename == 'images'){
//var readurl = filePath '/' filename;
             //filePath "/" filename不能用/直接连接，Unix系统是”/“，Windows系统是”\“
           //  console.log(path.join(filePath,filename));
             var name = filename;
             readFile(path.join(filePath,filename),name);
         }
      }
    });
  });
});
//获取后缀名
function getdir(url){
  var arr = url.split('.');
  var len = arr.length;
  return arr[len-1];
}
//获取文件数组
function readFile(readurl,name){
  console.log(name);
  var name = name;
  fs.readdir(readurl,function(err,files){
    if(err){console.log(err);return;}
    files.forEach(function(filename){
     // console.log(path.join(readurl,filename));
      fs.stat(path.join(readurl,filename),function(err, stats){
        if (err) throw err;
        //是文件
        if(stats.isFile()){
          var newUrl=remotePath name '/' filename;
          fileArr.push(newUrl);
          writeFile(fileArr)
        //是子目录
        }else if(stats.isDirectory()){
          var dirName = filename;
          readFile(path.join(readurl,filename),name '/' dirName);
          //利用arguments.callee(path.join())这种形式利用自身函数，会报错
          //arguments.callee(path.join(readurl,filename),name '/' dirName);
        }
      });
    });
  });
}
// 写入到filelisttxt文件
function writeFile(data){
  var data = data.join("\n");
  fs.writeFile(filePath "/" "filelist.txt",data '\n',function(err){
    if(err) throw err;
    console.log("写入成功");
  });
