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 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

  extractdir(dirpath)
