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"

if(os.system(cmd)==0):
state=True
else:
for psd in psds:

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 :

errorinfo.write("解压出错！\n")
traceback.print_exc(file=errorinfo)

else:
print("输入错误！请重新输入！")
