用python解压分析jar包实例

yipeiwu_com7年前 (2020-03-06)Python基础

写这个玩意的背景：在u8多渠道打包里，需要分析jar包，并把里面的文件按目录和类型分别放在root和assets文件夹里，之前师兄都是手动解压，一个一个文件夹找文件，效率比较低，刚好最近手上的android项目已经做完了，就决定写一个自动化分析jar文件并复制粘贴到指定文件夹的脚本。

    if ".idea" not in dir:
      classify(dir)

  sumfilelist = os.listdir(os.getcwd())
  for dir in sumfilelist:
    if "libs" in dir:
      jieyajar(dir)

  files = os.listdir(dir)
  for jars in files:
    if "jar" in jars:
      zfile = zipfile.ZipFile('libs/' + jars, 'r')
      if not os.path.exists(os.getcwd() + '/jarlog/' + jars):
        os.makedirs(os.getcwd() + '/jarlog/' + jars)
      zfile.extractall(os.getcwd() + '/jarlog/' + jars)

      zfile.close
 
  for file in os.listdir(os.getcwd()):

      classify(file)

#         shutil.copy(path,os.path.dirname(os.getcwd())+'/root/'+os.path.dirname(path))
#   else :
#     list = os.listdir(path)
#     for dir in list:
#       classify(path+"/"+dir)
 
def classify(path):
  global count
  if os.path.isfile(path):
    if ".class" not in path:
      if not os.path.exists(os.getcwd() + '/root/' + os.path.dirname(path)):
        os.makedirs(os.getcwd() + '/root/' + os.path.dirname(path))
      shutil.copy(path, os.getcwd() + '/root/' + os.path.dirname(path))
  else:
    if 'assets' in path and count == 1:
      count = count + 1
      shutil.copytree(os.getcwd()+'/'+path, os.getcwd() + '/assets')
    elif 'META-INF' not in path:
      list = os.listdir(path)
      for dir in list:
        classify(path + "/" + dir)
 
 
# getSumDir()
getlibDir()

嗯，主要就是对文件夹和文件的操作。。
