Question

我仍在使用python27。

升级我的boto安装时，得到以下输出：

$ pip install --upgrade boto3
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

如您所见，它安装了boto3-1.9.167 botocore-1.12.167

boto是撰写此问题时的最新版本：https://github.com/boto/boto3/releases/tag/1.9.167

但是，我在查找任何发行说明时遇到了麻烦。我只想确保此版本的boto中支持和使用AWS Sign v4。

如何验证？

Answer 1

botocore changelog表示从1.7.51版本开始，所有s3请求默认都使用sigv4。由于boto3基于botocore，因此您可以放心地假设您下载的版本支持sigv4。

如何验证AWS Sign v4中的支持？
