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！")
