Python zipfile从二进制文件中删除执行权限

解决这个问题的最简单方法是通过继承ZipFile并更改extract()(或在扩展版本中修补.默认情况下它是：

def extract(self,member,path=None,pwd=None):
    """Extract a member from the archive to the current working directory,using its full name. Its file information is extracted as accurately
       as possible. `member' may be a filename or a ZipInfo object. You can
       specify a different directory using `path'.
    """
    if not isinstance(member,ZipInfo):
        member = self.getinfo(member)

    if path is None:
        path = os.getcwd()

    return self._extract_member(member,path,pwd)

应该更改最后一行以实际根据原始属性设置模式.你可以这样做：

import os
from zipfile import ZipFile,ZipInfo

class MyZipFile(ZipFile):

    def extract(self,pwd=None):
        if not isinstance(member,ZipInfo):
            member = self.getinfo(member)

        if path is None:
            path = os.getcwd()

        ret_val = self._extract_member(member,pwd)
        attr = member.external_attr >> 16
        os.chmod(ret_val,attr)
        return ret_val


with MyZipFile('test.zip') as zfp:
    zfp.extractall()

(以上是基于Python 3.5并假设zipfile名为test.zip)
