這篇文章主要介紹了python使用7z解壓apk包的方法,涉及Python的shell命令調用技巧,非常具有實用價值,需要的朋友可以參考下

本文實例講述了python使用7z解壓apk包的方法。分享給大家供大家參考。具體如下：

這段代碼通過shell調用7z對apk包進行解壓縮

def run_shell(command, mayFreeze=False):

def check_retcode(retcode, cmd):

if 0 != retcode:

print >> sys.stderr, 'err executing ' + cmd + ':', retcode

sys.exit(retcode)

def read_close(f):

f.seek(0)

d = f.read()

f.close()

return d

#print >> sys.stderr, '-- Executing', command

if mayFreeze:

tempout, temperr = tempfile.TemporaryFile(), tempfile.TemporaryFile()

#open(os.devnull, 'w')

p = subprocess.Popen(command, stdout=tempout, stderr=temperr)

p.wait()

output, errout = read_close(tempout), read_close(temperr)

else:

p=subprocess.Popen(command,stdout=subprocess.PIPE,stderr=subprocess.PIPE)

output = p.stdout.read()

p.wait()

errout = p.stderr.read()

p.stdout.close()

p.stderr.close()

#check_retcode(p.returncode, command)

return (output.strip(), errout.strip())

#z7 is the full path to 7z.exe

#at times you have to encode the command into GBK/UTF8

run_shell(u'{0} -y -o"{1}" {2} x "{3}"'.format(z7, tempdir, icon, apk))

shutil.copy(u'{0}/{1}'.format(tempdir,os.path.basename(icon)),dst_path)
