// ZipFiles compresses one or many files into a single zip archive file.
//壓縮多個檔案到一個檔案裡面
// Param 1: 輸出的zip檔案的名字
// Param 2: 需要新增到zip檔案裡面的檔案
//Param 3: 由於file是絕對路徑，打包後可能不是想要的目錄，oldform就是filename中需要被替換的掉的路徑
//Param 4: 要替換成的路徑
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新增到zip中
for _, file := range files {
zipfile, err := os.Open(file)
if err != nil {
return err
}
defer zipfile.Close()
// 獲取file的基礎資訊
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() 就可以把檔案儲存的路徑替換成我們自己想要的了，如下面
header.Name = strings.Replace(file, oldform, newform, -1)
// 優化壓縮
// 更多參考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",
}
//保留原來檔案的結構
err := ZipFiles("/Users/Jack/Downloads/QQreceiver/test.zip", fileList, "","")
if err != nil {
fmt.Println(err)
}
}
// 執行之後
//在對應目錄下生成了我們定義的zip檔案 ➜QQreceiver#ls test.zip test.zip ➜QQreceiver#pwd /Users/Jack/Downloads/QQreceiver //解壓test.zip ➜QQreceiver# ls Userstest.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.txtconfig.json xzwx_client Users/Jack/Downloads/QQreceiver/72bian_log/xzwx_client: md5.txt //可以看到test打包的是檔案的絕對路徑，如果這個test.zip是我們要更新的程式的目錄，這樣肯定是不能用的
使用方法 二：
替換成我們想要的結構
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",
}
//比如線上的程式的目錄為game ,"/Users/Jack/Downloads/QQreceiver/72bian_log/"下面的檔案為我們線game下的程式檔案內容
err := ZipFiles("/Users/Jack/Downloads/QQreceiver/test.zip", fileList, "/Users/Jack/Downloads/QQreceiver/72bian_log","game/")
if err != nil {
fmt.Println(err)
}
}
執行之後
//在對應目錄下生同樣生成了我們定義的zip檔案 ➜QQreceiver#ls test.zip test.zip ➜QQreceiver#pwd /Users/Jack/Downloads/QQreceiver //解壓test.zip ➜QQreceiver# ls gametest.zip ➜QQreceiver# ls -R game anal.txtconfig.json xzwx_client game/xzwx_client: md5.txt //上面正好是我們需要的目錄
