python tar文件如何将文件提取到流中 [英] python tar file how to extract file into stream

问题描述

我想提取一个压缩文件夹，但不是直接使用 .extractall()，我想将文件提取到流中，以便我可以自己处理流.是否可以使用 tarfile 来实现?或者有什么建议?

I am trying to extract a zipped folder but instead of directly using .extractall(), I want to extract the file into stream so that I can handle the stream myself. Is it possible to do it using tarfile? Or is there any suggestions?

推荐答案

您可以使用 .extractfile()file 对象> 方法.循环遍历 tarfile.TarFile() 实例以列出所有条目:

You can obtain each file from a tar file as a python file object using the .extractfile() method. Loop over the tarfile.TarFile() instance to list all entries:

import tarfile

with tarfile.open(path) as tf:
    for entry in tf:  # list each entry one by one
        fileobj = tf.extractfile(entry)
        # fileobj is now an open file object. Use `.read()` to get the data.
        # alternatively, loop over `fileobj` to read it line by line.
