ExecutionContext.setSigner介绍

[英]There is in general no need to set the signer in the execution context, since the signer for each request may differ depending on the URI of the request. The exception is S3 where the signer is currently determined only when the S3 client is constructed. Hence the need for this method. We may consider supporting a per request level signer determination for S3 later on.
[中]通常不需要在执行上下文中设置签名者，因为根据请求的URI，每个请求的签名者可能不同。S3是个例外，当前只有在构造S3客户端时才确定签名者。因此需要这种方法。我们可以考虑稍后支持S3的每个请求级签名者确定。
