go使用archive/zip原生包解压zip文件

go-zip-uncompress-native

package main

import (
	"archive/zip"
	"fmt"
	"io"
	"os"
)

func main() {
	if err := unzip(); err != nil {
		fmt.Println(err)
	}
}
func unzip() error {
	or, err := zip.OpenReader(`unpack.zip`)
	if err != nil {
		return err
	}
	for _, file := range or.Reader.File {
		if file.FileInfo().IsDir() {
			if err := os.MkdirAll(file.Name, 0644); err != nil {
				return err
			}
			continue
		}
		f, err := file.Open()
		if err != nil {
			return err
		}
		defer f.Close()
		cfile, err := os.Create(file.Name)
		if err != nil {
			return err
		}
		if _, err := io.Copy(cfile, f); err != nil {
			return err
		}
		cfile.Close()
	}
	or.Close()
	return nil
