如何解决压缩文件夹最终会出错，具体取决于1个文件
我有一个可以压缩包含LibreOffice Data的文件夹的功能。 （请参阅底部）
当我使用一个content.xml模板运行它时，它可以很好地工作并将其返回给我

文件content.xml的每个点都相同，但唯一的变化是文件大小
Normal version: -rw-r--r-- 1 root root 43580 Aug 20 09:59 content.xml
Defective version: -rw-r--r-- 1 root root 43416 Aug 20 09:56 content.xml
也许有人知道发生了什么事吗？
使用的功能
package util
import (
"os"
"archive/zip"
"io/ioutil"
"aptacrm/vars"
)
func ZipFolder(folder string,output string) {
var outFile,_ = os.Create(output)
defer outFile.Close()
var writer = zip.NewWriter(outFile)
processFolder(writer,folder,"")
writer.Close()
}
func processFolder(writer *zip.Writer,basePath string,baseInZip string) {
var files,_ = ioutil.ReadDir(basePath)
for _,file := range files {
var realFilePath = basePath + file.Name()
var zipFilePath = baseInZip + file.Name()
vars.Logger.Info("Processing",realFilePath)
var isDir = file.IsDir()
if isDir {
processFolder(writer,realFilePath + "/",baseInZip + file.Name() + "/")
} else {
var fileData,e1 = ioutil.ReadFile(realFilePath)
if e1 != nil {
vars.Logger.Info("1")
vars.Logger.Info(e1.Error())
}
var fileWriter,e2 = writer.Create(zipFilePath)
if e2 != nil {
vars.Logger.Info("2")
vars.Logger.Info(writer)
vars.Logger.Info(zipFilePath)
vars.Logger.Info(realFilePath)
vars.Logger.Info(fileWriter)
vars.Logger.Info(e2.Error())
}
var _,e3 = fileWriter.Write(fileData)
if e3 != nil {
vars.Logger.Info("3")
vars.Logger.Info(e3.Error())
}
}
}
}
其他信息：
- 通过golang docker容器
golang:alpine进入1.15.0版 - vars.Logger是
stdlog.GetFromFlags()库中的github.com/alexcesaro/log/stdlog
解决方法
感谢Marc为我提供了良好的指导！
问题出在我的输出文件的命名上，其中包含/，而os.Create返回了一个错误，其中包含我需要修复的所有指示！
