How to use signed URL for kinesis-video-signaling get-ice-server-config API?

[overheat]

I need a rust version function for this typescript fuction:
https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-js/blob/de209884fcd388c3fea4937a5b99354ef9519af3/src/SigV4RequestSigner.ts#L43

How to implemented such code by aws-sdk-rust?

We don't have a Rust equivalent of the "Amazon Kinesis Video Streams with WebRTC" high-level library. You can submit a feature request for it but I don't expect we'll get to it any time soon.

In the meantime, if you'd like to take a look at our sigv4 signing code, it can be found here.

Admittedly, the signing API is not ergonomic today, but nevertheless you can also find an example here. Since the link above shows a function that creates a URL with query params, you probably want to have a SigningSettings with a field signature_location set to SignatureLocation::QueryParams.

Yes, now I still need 2 more item X-Amz-ChannelARN and X-Amz-ClientId in the signed URL.
Do you know how to add them manually?

[ysaito1001]

Referring back to the example, after the end of the last line

signing_instructions.apply_to_request_http1x(&mut my_req);

maybe you can call .uri_mut on my_req to include X-Amz-ChannelARN and X-Amz-ClientId (assuming their values do not need to be part of the signing process and can be added to the signed URL) ?

@ysaito1001 right!
only one thing that for ChannelARN there are some characters like : need to be translate to %3. Any convenient method suggestion?

I'd give fmt_string a try (example usage).
