使用 Node.js 将文件系统中的目录结构转换为 JSON

本文介绍了使用 Node.js 将文件系统中的目录结构转换为 JSON的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有这样的文件结构:

root |_ fruits |___ apple |______images |________ apple001.jpg |________ apple002.jpg |_ animals |___ cat |______images |________ cat001.jpg |________ cat002.jpg

我想，使用 Javascript 和 Node.js，监听这个根目录和所有子目录，并创建一个镜像这个目录结构的 JSON，每个节点包含类型、名称、路径和子项:

I would like to, using Javascript and Node.js, listen to this root directory and all sub directories and create a JSON which mirrors this directory structure, each node contains type, name, path, and children:

data = [ { type: "folder", name: "animals", path: "/animals", children: [ { type: "folder", name: "cat", path: "/animals/cat", children: [ { type: "folder", name: "images", path: "/animals/cat/images", children: [ { type: "file", name: "cat001.jpg", path: "/animals/cat/images/cat001.jpg" }, { type: "file", name: "cat001.jpg", path: "/animals/cat/images/cat002.jpg" } ] } ] } ] } ];

这是一个咖啡脚本 JSON:

Here's a coffeescript JSON:

data = [ type: "folder" name: "animals" path: "/animals" children : [ type: "folder" name: "cat" path: "/animals/cat" children: [ type: "folder" name: "images" path: "/animals/cat/images" children: [ type: "file" name: "cat001.jpg" path: "/animals/cat/images/cat001.jpg" , type: "file" name: "cat001.jpg" path: "/animals/cat/images/cat002.jpg" ] ] ] ]

如何在 django 视图中获取这种 json 数据格式?(python)

推荐答案

这是一个草图.错误处理留给读者作为练习.

Here's a sketch. Error handling is left as an exercise for the reader.

var fs = require('fs'), path = require('path') function dirTree(filename) { var stats = fs.lstatSync(filename), info = { path: filename, name: path.basename(filename) }; if (stats.isDirectory()) { info.type = "folder"; info.children = fs.readdirSync(filename).map(function(child) { return dirTree(filename + '/' + child); }); } else { // Assuming it's a file. In real life it could be a symlink or // something else! info.type = "file"; } return info; } if (module.parent == undefined) { // node dirTree.js ~/foo/bar var util = require('util'); console.log(util.inspect(dirTree(process.argv[2]), false, null)); }
