Windows XP 환경에서 gRPC를 도입을 고려해봤던

제가 아는 범주 내로는 gRPC는 HTTPS 통신이 필수사항이라

도입을 포기했던 경험이 있습니다.

MS 공식 문서에 따르면 IIS+ 에서 지원한다고 하는 여기서 말하는 + 가 어떤건지는 정확히 모르겠습니다만, IIS 환경이여서 안되는건 아니지 않을까 싶습니다.

gRPC가 https가 아닌 http를 지원하던가요?

question

I have a sample ASP.NET Core 8 application, using the default gRPC template , ad…ded Serilog and "Grpc.AspNetCore.Server.Reflection, all works fine locally. Using the default greeter service sample. I am trying to verify that I can deploy this to my demo server. But, deploying to IIS (Windows 10 machine version 22H2), IIS 10.0.19041.1 does not work, I get this log: ``` 2023-08-27 17:01:27.632 +02:00 [INF] Request finished HTTP/2 POST https://grpc.secure.nu/greet.Greeter/SayHello - 200 null application/grpc 2.6704ms 2023-08-27 17:01:28.929 +02:00 [INF] Request starting HTTP/2 POST https://grpc.secure.nu/greet.Greeter/SayHello - application/grpc null 2023-08-27 17:01:28.930 +02:00 [DBG] 3 candidate(s) found for the request path '/greet.Greeter/SayHello' 2023-08-27 17:01:28.930 +02:00 [DBG] Endpoint 'gRPC - /greet.Greeter/SayHello' with route pattern '/greet.Greeter/SayHello' is valid for the request path '/greet.Greeter/SayHello' 2023-08-27 17:01:28.930 +02:00 [DBG] Endpoint 'gRPC - Unimplemented method for greet.Greeter' with route pattern 'greet.Greeter/{unimplementedMethod:grpcunimplemented}' is valid for the request path '/greet.Greeter/SayHello' 2023-08-27 17:01:28.930 +02:00 [DBG] Endpoint 'gRPC - Unimplemented service' with route pattern '{unimplementedService}/{unimplementedMethod:grpcunimplemented}' is valid for the request path '/greet.Greeter/SayHello' 2023-08-27 17:01:28.930 +02:00 [DBG] Request matched endpoint 'gRPC - /greet.Greeter/SayHello' 2023-08-27 17:01:28.930 +02:00 [DBG] The endpoint does not specify the IRequestSizeLimitMetadata. 2023-08-27 17:01:28.930 +02:00 [INF] Executing endpoint 'gRPC - /greet.Greeter/SayHello' 2023-08-27 17:01:28.930 +02:00 [DBG] Reading message. 2023-08-27 17:01:28.930 +02:00 [DBG] Sending message. 2023-08-27 17:01:28.930 +02:00 [ERR] Error when executing service method 'SayHello'.

Works fine locally on IIS Express and Kestrel.

github issue 에서도 windows 10은 지원 안한다고 하네요.
