我正在嘗試壓縮包含一些空子目錄的現有目錄。這是文件夾結構。parent/├── child│ └── child.txt├── empty-folder└── parent.txt2 directories, 2 files這是源代碼。它寫入所有有文件的子目錄。但它跳過了一個空的子目錄。有沒有辦法在 zip 文件中添加一個空子目錄？提前致謝。package mainimport ( "archive/zip" "fmt" "io" "os" "path/filepath")// check for error and stop the executionfunc checkForError(err error) { if err != nil { fmt.Println("Error - ", err) os.Exit(1) }}const ( ZIP_FILE_NAME = "example.zip" MAIN_FOLDER_NAME = "parent")// Main functionfunc main() { var targetFilePaths []string // get filepaths in all folders err := filepath.Walk(MAIN_FOLDER_NAME, func(path string, info os.FileInfo, err error) error { if info.IsDir() { return nil } // add all the file paths to slice targetFilePaths = append(targetFilePaths, path) return nil }) checkForError(err) // zip file logic starts here ZipFile, err := os.Create(ZIP_FILE_NAME) checkForError(err) defer ZipFile.Close() zipWriter := zip.NewWriter(ZipFile) defer zipWriter.Close() for _, targetFilePath := range targetFilePaths { file, err := os.Open(targetFilePath) checkForError(err) defer file.Close() // create path in zip w, err := zipWriter.Create(targetFilePath) checkForError(err) // write file to zip _, err = io.Copy(w, file) checkForError(err) }}

要編寫一個空目錄，您只需要Create使用帶有尾隨路徑分隔符的目錄路徑進行調用。
package main
import (
"archive/zip"
"fmt"
"io"
"log"
"os"
"path/filepath"
)
const (
ZIP_FILE_NAME = "example.zip"
MAIN_FOLDER_NAME = "parent"
)
type fileMeta struct {
Path string
IsDir bool
}
func main() {
var files []fileMeta
err := filepath.Walk(MAIN_FOLDER_NAME, func(path string, info os.FileInfo, err error) error {
files = append(files, fileMeta{Path: path, IsDir: info.IsDir()})
return nil
})
if err != nil {
log.Fatalln(err)
}
z, err := os.Create(ZIP_FILE_NAME)
if err != nil {
log.Fatalln(err)
}
defer z.Close()
zw := zip.NewWriter(z)
defer zw.Close()
for _, f := range files {
path := f.Path
if f.IsDir {
path = fmt.Sprintf("%s%c", path, os.PathSeparator)
}
w, err := zw.Create(path)
if err != nil {
log.Fatalln(err)
}
if !f.IsDir {
file, err := os.Open(f.Path)
if err != nil {
log.Fatalln(err)
}
defer file.Close()
if _, err = io.Copy(w, file); err != nil {
log.Fatalln(err)
}
}
}
}
