Using jar to decompress Python

Time:2020-10-14

Background: in the U8 multi-channel package, you need to analyze the jar package and put the files in the root and assets folders according to the directory and type. Before, the elder martial brother manually decompressed the files, and found the files one by one, which was inefficient. Just recently, the Android project in hand had been completed, so he decided to write an automatic analysis jar file and copy and paste it into Specifies the script for the folder.

import os
import shutil
import zipfile
 
count = 1
def getSumDir():
  sumfilelist = os.listdir(os.getcwd())
  for dir in sumfilelist:
    if ".idea" not in dir:
      classify(dir)
 
 
def getlibDir():
  sumfilelist = os.listdir(os.getcwd())
  for dir in sumfilelist:
    if "libs" in dir:
      jieyajar(dir)
 
 
def 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)
 
      if not os.path.exists(os.getcwd() + '/jars/'):
        os.makedirs(os.getcwd() + '/jars/')
      zfile.extractall(os.getcwd() + '/jars/')
      zfile.close
 
  for file in os.listdir(os.getcwd()):
    if "jars" in file:
      classify(file)
 
 
# def classify(path):
#   if os.path.isfile(path):
#     if ".class" not in path:
#       if "assets" in os.path.dirname(path):
#         if not os.path.exists(os.path.dirname(os.getcwd()) + '/assets/' + os.path.dirname(path)):
#           os.makedirs(os.path.dirname(os.getcwd()) + '/assets/' + os.path.dirname(path))
#         shutil.copy(path, os.path.dirname(os.getcwd()) + '/assets/' + os.path.dirname(path))
#       else:
#         if not os.path.exists(os.path.dirname(os.getcwd())+'/root/'+os.path.dirname(path)):
#          os.makedirs(os.path.dirname(os.getcwd())+'/root/'+os.path.dirname(path))
#         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()

Well, it’s mainly about the operation of folders and files..

The above example of using Python to decompress and analyze jar package is the whole content shared by Xiaobian. I hope to give you a reference, and I hope you can support developeppaer more.
