nodejs遍历目录的方法

1. 使用fs模块遍历

1.1 同步操作

var fs = require("fs")
var path = require("path")

var root = path.join(__dirname)

readDirSync(root)
function readDirSync(path){
    var pa = fs.readdirSync(path);
    pa.forEach(function(ele,index){
        var info = fs.statSync(path+"/"+ele)
        if(info.isDirectory()){
            console.log("dir: "+ele)
            readDirSync(path+"/"+ele);
        }else{
            console.log("file: "+ele)
        }
    })
}

1.2. 异步操作

var fs = require("fs")
var path = require("path")

var root = path.join(__dirname)

readDir(path.join(root))
function readDir(path){
    fs.readdir(path,function(err,menu){
        if(!menu)
            return;
        menu.forEach(function(ele){
            fs.stat(path+"/"+ele,function(err,info){
                if(info.isDirectory()){
                    console.log("dir: "+ele)
                    readDir(path+"/"+ele);
                }else{
                    console.log("file: "+ele)
                }
            })
        })
    })
}

2. 使用walk模块遍历

var walk = require('walk')

var root = path.join(__dirname)
var files = [],dirs = [];

getFileList(path.join(root))

function getFileList(path){
    var walker  = walk.walk(path, { followLinks: false });

    walker.on('file', function(roots, stat, next) {
        files.push(roots + '/' + stat.name);
        next();
    });

    walker.on('directory', function(roots, stat, next) {
        dirs.push(roots + '/' + stat.name);
        next();
    });
    walker.on('end', function() {
        console.log("files "+files);
        console.log("dirs "+dirs);
    });
}
