问题描述

大家晚安.我可能遇到了一些简单的递归函数的问题.问题是递归列出给定文件夹及其子文件夹中的所有文件.

Good night everyone. I'm having trouble with probably some simple recursive function. The problem is to recursively list all files in a given folder and its subfolders.

目前，我已经设法使用一个简单的函数列出目录中的文件:

For the moment, I've managed to list files in a directory using a simple function:

fs.readdirSync(copyFrom).forEach((file) => {
  let fullPath = path.join(copyFrom, file);

  if (fs.lstatSync(fullPath).isDirectory()) {
    console.log(fullPath);
  } else {
    console.log(fullPath);
  }
});

我尝试了各种方法，例如 do{} ... while()，但我无法做到正确.由于我是javascript的初学者，我终于决定向你们寻求帮助.

I've tried various methods like do{} ... while() but I can't get it right. As I'm a beginner in javascript, I finally decided to ask for help from you guys.

推荐答案

只需添加一个递归调用即可:

Just add a recursive call and you are done:

 function traverseDir(dir) {
   fs.readdirSync(dir).forEach(file => {
     let fullPath = path.join(dir, file);
     if (fs.lstatSync(fullPath).isDirectory()) {
        console.log(fullPath);
        traverseDir(fullPath);
      } else {
        console.log(fullPath);
      }  
   });
 }
