Make Callcontext injectable

[mgravell]

No; the call-context is strictly per operation - it has a very different lifetime than the service (on the native version, the service is essentially a singleton; on Kestrel, the service lifetime is configurable in many different ways). I'd also rather avoid some kind of ambient thread-local API.

Can you clarify: what is the scenario where you need it, but are reluctant to make it a parameter?

[ElderJames]

I want to get data from headers of the current HttpContext,like jwt,better to make the IHttpContextAccssor work in the service on Kestrel.

[mgravell]

OK; I understand what you mean.

@JamesNK: before I go too far down the rabbit-hole investigating this - is there any ambient gRPC context already implemented in your bits?

[ElderJames]

And I also need to get the complate signal from client at duplex streaming mode

[mgravell]

@ElderJames that sounds like a very different thing, but that should currently materialize as the end of the IAsyncEnumerable<T> sequence. Is that now working for you? Or are you after something different? Perhaps an example of your intent would help there (just pretend that what you wanted existed)

[ElderJames]

Ok, yield break for IAsyncEnumerable is work.

[mgravell]

I'm assuming that HttpContextAccessorExtensions.GetServerCallContext / .GetCallContext do what is needed here
