python利用7z批量解压rar的实现

一开始我使用了rarfile这个库，奈何对于含有密码的压缩包支持不好，在linux上不抛出异常；之后有又尝试了unrar。。比rarfile还费劲。。

所以用了调用系统命令的方法，用7z来解压

通过apt可以安装上7z-full和7z的rar插件

有一个地方要注意 -o 和-p与后面的目录、密码之间没有空格！！

同样可以用这个代码暴力破解压缩包密码

# coding:utf-8 

import os

import zipfile

import traceback

import time

import shutil

import sys,getopt

 

succeedpath=""

unsucceedpath=""

psds={"2018","123456"}

 

 

opts,args=getopt.getopt(sys.argv[1:],"p:")

path=args[0]

for psd in args[1:]:

  psds.add(psd)

#for op,value in opts:

#  if op in ("-p","--password"):

#    psds.add(value)

 

 

def mkdirs(dirpath):

  global succeedpath,unsucceedpath

  succeedpath=os.path.join(dirpath,"0.succeed")

  unsucceedpath=os.path.join(dirpath,"0.unsucceed")

  if(not os.path.exists(succeedpath)):

    os.makedirs(succeedpath)

  if(not os.path.exists(unsucceedpath)):

    os.makedirs(unsucceedpath)

 

def extractdir(path):

  for filename in os.listdir(path):

    filepath=os.path.join(path,filename)

    if(os.path.isfile(filepath)):

      extractfile(filepath)

 

 

def extractfile(path):

  (dirpath,filen)=os.path.split(path)

  print("解压"+filen+"   ing...")

  try:

    if(filen.endswith(".rar") or filen.endswith(".zip")):

      path=os.path.abspath(path)

      dirpath=os.path.abspath(dirpath)

      cmd="7z x "+path+" -o"+dirpath+" -y "+" -p"

      state=False

      if(os.system(cmd)==0):

        state=True

      else:

        for psd in psds:

          cmdp="7z x "+path+" -p"+psd+" -y "+" -o"+dirpath

          if(os.system(cmdp)==0):

            state=True

            break

    else:

      return

    if (state):

      shutil.move(path,succeedpath)

    else:

      shutil.move(path,unsucceedpath)

      with open(os.path.join(dirpath,"errorinfo.txt"),"a+") as errorinfo:

        errorinfo.write("time:"+str(time.time())+"\n")

        errorinfo.write("解压出错！\n可能是密码错误！\n")

  except :

    with open(os.path.join(dirpath,"errorinfo.txt"),"a+") as errorinfo:

      errorinfo.write("time:"+str(time.time())+"\n")

      errorinfo.write("解压出错！\n")

      traceback.print_exc(file=errorinfo)

    shutil.move(path,unsucceedpath)

 
if(os.path.isdir(path)):

  dirpath=path

  mkdirs(dirpath)

  extractdir(dirpath)

elif(os.path.isfile(path)):

  filepath=path

  (dirpath,filename)=os.path.split(path)

  mkdirs(dirpath)

  extractfile(path)

else:

  print("输入错误！请重新输入！")
