【问题描述】：

我将 AWS Lambda 与 Python 结合使用，当发生错误时，我的日志中出现了奇怪的垃圾。有人知道这是什么吗？

我的堆栈是带有 Zappa 框架 https://github.com/Miserlou/Zappa、Flask 和 Python 2.7 的 AWS Lambda。

【问题讨论】：

可能是编码错误响应？见：DecodeAuthorizationMessage

标签： python aws-lambda amazon-cloudfront amazon-cloudwatch

【解决方案1】：

当用户执行未经授权的请求时，AWS 会返回 Client.UnauthorizedOperation 响应，其中包含请求操作的编码详细信息和失败原因。只有允许的用户才能使用命令行或 API 破译内容。但解码需要该 IAM 用户的额外权限。

对于 CLI： 使用'decode-authorization-message --encoded-message <value>'。更多信息请参考http://docs.aws.amazon.com/cli/latest/reference/sts/decode-authorization-message.html

对于 API： http://docs.aws.amazon.com/STS/latest/APIReference/API_DecodeAuthorizationMessage.html
