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");  });}
