内存中的python tarfile递归提取

Question

我有一个包含压缩 tar 文件的 tar 文件。像这样:

gnomeAware@devserv:~$ tar tf test.tar
File1.tar.gz
File2.tar.gz
File3.tar.gz
File4.tar.gz

tarfile 需要一个字符串作为要打开的文件。有没有办法向它传递一个文件对象？

tar = tarfile.open('test.tar', 'r') # Unpack tar
for item in tar:
  Bundle=tar.extractfile(item) # Pull out the file
  t = tarfile.open(Bundle, "r:gz") # Unpack tar
  for tItem in t:
  ...

谢谢。

下面是读取存档中每个文件数据的方法:

import tarfile

filename = "archive.tar.gz"

with tarfile.open(filename, "r:gz") as file:
    # don't use file.members as it's 
    # not giving nested files and folders
    for member in file:
        # You need additional code to save the data into a list.
        file_content_byte = file.extractfile(member.name).read()

如果您已经知道存档中文件的名称，您可以这样做:

import tarfile

filename = "archive.tar.gz"

with tarfile.open(filename, "r:gz") as file:
    file_content_byte = file.extractfile("file.txt").read()
