gzip解压到.json文件

Question

Below is my solution, where I return the json content(body) as response.gzip, after extraction there is a file, an object bytes without any extension like "response" only, Of course, if I open it directly from the notepad, I can see the text. question, what can I do so that when I unzip it I have the json directly and not a file without an extension? where am I going wrong?

    body = {"A": 1, "K": True, "L": None}
    buffer = io.BytesIO()
    with gzip.GzipFile(fileobj=buffer, mode="w") as buffers:
        buffers.write((json.dumps(body).encode('utf-8')))
    return func.HttpResponse(body=buffer.getvalue(), status_code=int(status_code), headers={
        "Accept-encoding":"gzip,deflate",
        "Content-Type":"multipart/mixed",
        "Content-Disposition":"attachment; filename=response.gzip"})
