Package mainimport ("encoding/json"fmt"os"path/filepath"sort") func main () {rootpath: = "D:\\ projects" root: = FileNode {"projects", rootpath, [] * FileNode {}} fileInfo, _: = os.Lstat (rootpath) walk (rootpath, fileInfo, & root) data _: = json.Marshal (root) fmt.Printf ("% s", data)} type FileNode struct {Name string `json: "name" `Path string `json: "path" `FileNodes [] * FileNode `json: "children" `} func walk (path string, info os.FileInfo) Node * FileNode) {/ / list all directories and files under the current directory files: = listFiles (path) / / traverse these files for _, filename: = range files {/ / stitching full path fpath: = filepath.Join (path, filename) / / construct file structure fio _: = os.Lstat (fpath) / / add the current file as a child node to the directory child: = FileNode {filename, fpath, [] * FileNode {}} node.FileNodes = append (node.FileNodes, & child) / / if the current file traversing is a directory Enter the directory and recursively if fio.IsDir () {walk (fpath, fio, & child)}} return} func listFiles (dirname string) [] string {f, _: = os.Open (dirname) names _: = f.Readdirnames (- 1) f.Close () sort.Strings (names) return names} is it helpful for you to read the above content?
