如何在Python中gzip字节数组? [英] How to gzip a bytearray in Python?

问题描述

我在一个字节数组中有二进制数据，我想先gzip然后通过请求发布.我发现了如何gzip文件，但找不到字节数组.那么，如何通过Python gzip一个字节数组?

I have binary data inside a bytearray that I would like to gzip first and then post via requests. I found out how to gzip a file but couldn't find it out for a bytearray. So, how can I gzip a bytearray via Python?

推荐答案

看看Python的zlib-模块.

Have a look at the zlib-module of Python.

Python 3: zlib-模块

Python 3: zlib-module

一个简短的例子:

import zlib
compressed_data = zlib.compress(my_bytearray)

您可以通过以下方式再次解压缩数据:

You can decompress the data again by:

decompressed_byte_data = zlib.decompress(compressed_data)

Python 2: zlib-模块

Python 2: zlib-module

一个简短的例子:

import zlib
compressed_data = zlib.compress(my_string)

您可以通过以下方式再次解压缩数据:

You can decompress the data again by:

decompressed_string = zlib.decompress(compressed_data)

如您所见，Python 3使用字节数组，而Python 2使用字符串.

As you can see, Python 3 uses bytearrays while Python 2 uses strings.
