在Tarfile中打开Tarfile

Question

我正在开发一个程序，该程序应该从tarfile中获取信息（大小和名称）。现在我不知道如何从对象中获取tarfile的信息。那是我的代码：

import tarfile
from io import BytesIO
import re


def open_tars_logic(name_s, tar_bytes):
    filedata = BytesIO(tar_bytes.read()) # Here I need a solution
    with tarfile.open(fileobj=filedata) as new_tar:
        all_names = new_tar.getnames()
        for name in new_tar.getnames()
            if re.search(r'\.tar\.gz$', name) is not None:
                name_f = open_tars_logic(name, tar_bytes)
                all_names.append(name_f)
    return all_names

# "tar_file" is the path to the tarfile
def open_tar(tar_file):
    with open(tar_file, "rb") as tar_bytes:
        with tarfile.open(tar_file, "r") as parent_tar:
            all_names = parent_tar.getnames()
            for name in parent_tar.getnames():
                if re.search(r'\.tar\.gz$', name) is not None: # Search for other Tarfiles
                    name_f = open_tars_logic(name, tar_bytes)
                    all_names.append(name_f)
    return all_names

我暂时忽略大小。

这里是目标文件的示例：

parent_tar

sup_tar

嘿，获取有关任何tarfile的信息：

import tarfile
import time

t = tarfile.open('example.tar.gz', 'r')
for info in t.getmembers():
    print(info.name)
    print('Modified:', time.ctime(info.mtime))
    print('Mode    :', oct(info.mode))
    print('Type    :', info.type)
    print('Size    :', info.size, 'bytes')
