导读：import ( "os" "archive/zip" "io" "fmt" "strings" ) // ZipFiles compresses one or many files into a single zip archive file. //压缩多个文件到一个文件里面 // Param 1: 输出的zip文件的名字 // Param 2: 需要添加到zip文件里面的文件 //Param 3: 由
import ( "os" "archive/zip" "io" "fmt" "strings" ) // ZipFiles compresses one or many files into a single zip archive file. //压缩多个文件到一个文件里面 // Param 1: 输出的zip文件的名字 // Param 2: 需要添加到zip文件里面的文件 //Param 3: 由于file是绝对路径，打包后可能不是想要的目录，oldform就是filename中需要被替换的掉的路径 //Param 4: 要替换成的路径 func ZipFiles(filename string,files []string,oldform,newform string) error { newZipFile,err := os.Create(filename) if err != nil { return err } defer newZipFile.Close() zipWriter := zip.NewWriter(newZipFile) defer zipWriter.Close() // 把files添加到zip中 for _,file := range files { zipfile,err := os.Open(file) if err != nil { return err } defer zipfile.Close() // 获取file的基础信息 info,err := zipfile.Stat() if err != nil { return err } header,err := zip.FileInfoHeader(info) if err != nil { return err } //使用上面的FileInforHeader() 就可以把文件保存的路径替换成我们自己想要的了，如下面 header.Name = strings.Replace(file,newform,-1) // 优化压缩 // 更多参考see http://golang.org/pkg/archive/zip/#pkg-constants header.Method = zip.Deflate writer,err := zipWriter.CreateHeader(header) if err != nil { return err } if _,err = io.Copy(writer,zipfile); err != nil { return err } } return nil
使用方法 一： func main() {
fileList := []string{
"/Users/Jack/Downloads/QQreceiver/72bian_log/anal.txt","/Users/Jack/Downloads/QQreceiver/72bian_log/config.json","/Users/Jack/Downloads/QQreceiver/72bian_log/xzwx_client/md5.txt",}
//保留原来文件的结构
err := ZipFiles("/Users/Jack/Downloads/QQreceiver/test.zip",fileList,"","")
if err != nil {
fmt.Println(err)
}
}
// 执行之后 //在对应目录下生成了我们定义的zip文件 ? QQreceiver# ls test.zip test.zip ? QQreceiver# pwd /Users/Jack/Downloads/QQreceiver //解压test.zip ? QQreceiver# ls Users test.zip ? QQreceiver# ls -R Users Jack Users/Jack: Downloads Users/Jack/Downloads: QQreceiver Users/Jack/Downloads/QQreceiver: 72bian_log Users/Jack/Downloads/QQreceiver/72bian_log: anal.txt config.json xzwx_client Users/Jack/Downloads/QQreceiver/72bian_log/xzwx_client: md5.txt //可以看到test打包的是文件的绝对路径，如果这个test.zip是我们要更新的程序的目录，这样肯定是不能用的 使用方法 二： func main() {
fileList := []string{
"/Users/Jack/Downloads/QQreceiver/72bian_log/anal.txt",}
//比如线上的程序的目录为game,"/Users/Jack/Downloads/QQreceiver/72bian_log/"下面的文件为我们线game下的程序文件内容
err := ZipFiles("/Users/Jack/Downloads/QQreceiver/test.zip","/Users/Jack/Downloads/QQreceiver/72bian_log","game/")
if err != nil {
fmt.Println(err)
}
}
执行之后 //在对应目录下生同样生成了我们定义的zip文件 ? QQreceiver# ls test.zip test.zip ? QQreceiver# pwd /Users/Jack/Downloads/QQreceiver //解压test.zip ? QQreceiver# ls game test.zip ? QQreceiver# ls -R game anal.txt config.json xzwx_client game/xzwx_client: md5.txt //上面正好是我们需要的目录 （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
