创建zip文件
golang提供了archive/zip
包来处理zip压缩文件,下面通过一个简单的示例来展示golang如何创建zip压缩文件:
func createZip(filename string) {// 缓存压缩文件内容buf := new(bytes.Buffer)// 创建zipwriter := zip.NewWriter(buf)defer writer.Close()// 读取文件内容content, _ := ioutil.ReadFile(filepath.Clean(filename))// 接收f, _ := writer.Create(filename)f.Write(content)filename = strings.TrimSuffix(filename, path.Ext(filename)) + ".zip"ioutil.WriteFile(filename, buf.Bytes(), 0644)
}
读取zip文件
读取zip文档过程与创建zip文档过程类似,需要解压后的文档目录结构创建:
func readZip(filename string) {zipFile, err := zip.OpenReader(filename)if err != nil {panic(err.Error())}defer zipFile.Close()for _, f := range zipFile.File {info := f.FileInfo()if info.IsDir() {err = os.MkdirAll(f.Name, os.ModePerm)if err != nil {panic(err.Error())}continue}srcFile, err := f.Open()if err != nil {panic(err.Error())}defer srcFile.Close()newFile, err := os.Create( f.Name)if err != nil {panic(err.Error())}defer newFile.Close()io.Copy(newFile, srcFile)}
}
