Node.js 使用遞歸實現(xiàn)遍歷文件夾中所有文件

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

//解析需要遍歷的文件夾，我這以E盤根目錄為例
var filePath = path.resolve('E:');

//調(diào)用文件遍歷方法
fileDisplay(filePath);

/**
 * 文件遍歷方法
 * @param filePath 需要遍歷的文件路徑
 */
function fileDisplay(filePath){
 //根據(jù)文件路徑讀取文件，返回文件列表
 fs.readdir(filePath,function(err,files){
 if(err){
 console.warn(err)
 }else{
 //遍歷讀取到的文件列表
 files.forEach(function(filename){
 //獲取當前文件的絕對路徑
 var filedir = path.join(filePath,filename);
 //根據(jù)文件路徑獲取文件信息，返回一個fs.Stats對象
 fs.stat(filedir,function(eror,stats){
 if(eror){
 console.warn('獲取文件stats失敗');
 }else{
 var isFile = stats.isFile();//是文件
 var isDir = stats.isDirectory();//是文件夾
 if(isFile){
 console.log(filedir);
 }
 if(isDir){
 fileDisplay(filedir);//遞歸，如果是文件夾，就繼續(xù)遍歷該文件夾下面的文件
 }
 }
 })
 });
 }
 });
}
