xml - 压缩文件夹最终会出错，具体取决于1个文件

标签 xml go zip libreoffice

我有一个功能来压缩包含LibreOffice Data的文件夹。 (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返回给我

有人知道发生了什么吗？
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())
            }
        }
    }
}
附加信息:
  • 通过golang docker容器转到版本1.15.0 golang:alpine
  • vars.Logger是stdlog.GetFromFlags()库
    • 中的github.com/alexcesaro/log/stdlog

    最佳答案

    感谢Marc给我很好的指导!
    问题来自于我的输出文件的命名，它包含了/，并且os.Create返回了一个错误，其中包含我需要修复的所有指示!
