when using Ktor client, is there a way to intercept a single request when making the call? <https://ktor.io/docs/client-http-send.html> looks like it'll intercept all calls on that client instance; I need to compute a signature over the request body and set it as a header for a single request

You have to filter out which request you want to intercept and also use in memory or persistent key value storage to save the value that you already have intercepted

ok, thanks; I suppose in that I case I want to manually serialize JSON, create the hash/signature over that and use a text body

though in that case, I think I need to pass the json serializer manually, there's no way to get that from the client, correct?

I wonder if you could put the interception logic as a lambda into the request attributes when building the request, and have an interceptor that pulls it out (if present) and otherwise does nothing?

it's a bit ugly but better than the alternative
