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

path=args[0]



for psd in args[1:]:



  psds.add(psd)



#for op,value in opts:



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



#    psds.add(value)

  global succeedpath,unsucceedpath

    os.makedirs(unsucceedpath)

  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
