python的zipfile实现文件目录解压缩

主要是 解决了压缩目录下 空文件夹 的压缩 和 解压缩问题

压缩文件夹的函数：

 # coding:utf-
 import os
 import zipfile

 def zipdir(dirToZip,savePath):
     if not os.path.isdir(dirToZip):
         raise Exception,u"zipDir Error,not a dir'%'".format(dirToZip)

     (saveDir,_)=os.path.split(savePath)
     if not os.path.isdir(saveDir):
         os.makedirs(saveDir)

     zipList = []

     for root,dirs,files in os.walk(dirToZip):
         for fileItem in files:
             zipList.append(os.path.join(root,fileItem))
         for dirItem in dirs:
             zipList.append(os.path.join(root,dirItem))

     zf = zipfile.ZipFile(savePath,'w',zipfile.ZIP_DEFLATED)

     for tar in zipList:
         if tar != dirToZip:
             zf.write(tar,tar.replace(dirToZip,''))
         else:
             zf.write(tar)

     zf.close()

解压的函数：

 def unZipFile(unZipSrc,targeDir):
     if not os.path.isfile(unZipSrc):
         raise Exception,u'unZipSrc not exists:{0}'.format(unZipSrc)

     if not os.path.isdir(targeDir):
         os.makedirs(targeDir)

     print(u'开始解压缩文件:{0}'.format(unZipSrc))

     unZf = zipfile.ZipFile(unZipSrc,'r')

     for name in unZf.namelist() :
         unZfTarge = os.path.join(targeDir,name)

         if unZfTarge.endswith("/"):
             #empty dir
             splitDir = unZfTarge[:-]
             if not os.path.exists(splitDir):
                 os.makedirs(splitDir)
         else:
             splitDir,_ = os.path.split(targeDir)

             if not os.path.exists(splitDir):
                 os.makedirs(splitDir)

             hFile = open(unZfTarge,'wb')
             hFile.write(unZf.read(name))
             hFile.close()

     print(u'解压缩完毕，目标文件目录:{0}'.format(targeDir))

     unZf.close()

调用：

if __name__ == '__main__':
    dirpath = os.path.abspath(u'.\\new')
    savepath = os.path.abspath(u'.\\new.zip')

#    zipdir(dirpath,savepath)
    unZipFile(savepath,dirpath)
