I would like to know how to add items to signedheaders.

[riruo]

I found this library for aws s4 authentication.

I was following along with the sample, but I need to add an optional entry other than host to the signedheaders.

However, I could not find a way to add the item in postasync.
(There was a test class, but that was incomplete as a code example)

Could you please tell me how to add arbitrary items to signedheaders to solve the above problem?

Hi @riruo.

The API of this library is pretty much the same as the API of HttpClient, and if you wan't to add e.g. headers to a request you create an instance of HttpRequestMessage where both method and headers are specified. You then pass the request representation to the SendAsync overload. Will this work for you?

Thanks for the answer!

By re-reading the AWS SDK documentation,
I was able to add a header to the S4 Signature with the same specifications as the HttpClient header, as you mentioned.

Thank you!
