Python 2.7 博托+；GoogleAppEnginer:“；无法获取URL:http://cloudfront.amazonaws.com/2010-11-01/distribution/<CF_DIST_ID>&引用；。拒绝连接

我正在谷歌应用引擎项目中运行这些代码

from boto import cloudfront

con = cloudfront.CloudFrontConnection(
    AWS_ACCESS_KEY,
    AWS_SECRET_KEY
)

distro_info = con.get_distribution_info(DOWNLOAD_DIST_ID)

当它执行到上面的最后一行时，我收到了一堆警告/错误消息，如下所示：

如果我把它作为一个独立的脚本来运行，那么根本就没有问题

有人知道问题出在哪里吗？

您正在使用http URL，而CloudFront API在http上不可用，仅在https上可用
