Example failed to run about grpcjsontranscoder HOT 4 CLOSED

Em cấu hình gateway theo Option 1 thì ko chạy được. Check source thì dòng 31 trong file DownStreamContextExtensions
var methodPath = context.DownstreamReRoute.DownstreamPathTemplate.Value; var grpcAssemblyResolver = context.HttpContext.RequestServices.GetService<GrpcAssemblyResolver>(); var methodDescriptor = grpcAssemblyResolver.FindMethodDescriptor(methodPath.Split('/').Last().ToUpperInvariant());
không lấy được grpcAssemblyResolver.

phải bổ sung theo hướng dẫn (Option 2) thì cần cấu hình thêm ở file StartUp.cs
services.AddGrpcJsonTranscoder(() => new GrpcAssemblyResolver().ConfigGrpcAssembly(typeof(Greeter.GreeterClient).Assembly));
thì mới chạy được.
=> Chỗ này e chưa hiểu là do e cấu hình sai hay hướng dẫn gộp chung phần cấu hình file StartUp.cs.

hi Bien, thank you for your information. I will do a double check due to the new .NET Core 3.0 SDK

HTTP/1.1 GET http://localhost:5000/say/Bob Ocelot.Errors.Middleware.ExceptionHandlerMiddleware:Debug: requestId: 0HLPSQDD4RDKQ:00000001, previousRequestId: no previous request id, message: ocelot pipeline started

The HTTP/1.1 should not be happen here, because of HTTP/2 is a default mode for gRPC.

I am working on it at https://github.com/vietnam-devs/coolstore-microservices/tree/develop/src/gateways/webapi-gateway

Of course, HTTP/2 is default for gRPC but in this case, I was using Postman for test Api-gateway. So, it is HTTP/1.1.
I am confused when reading the guide at Readme.md. That is config between Option 1 and Option 2.
Can you rewrite for Option 1? I saw that services is imported is very important. So, it should highlight.

@nguyenvanbien95 Agree with you about it. By the time, see the Ocelot gateway works with GrpcJsonTranscoder at https://github.com/vietnam-devs/coolstore-microservices/tree/develop/src/gateways/webapi-gateway, and it configures for the downstream services at https://github.com/vietnam-devs/coolstore-microservices/tree/develop/src/microservices

To get starting, run the command below

# at root coolstore-microservices project 
$ # docker-compose -f docker-compose.yml -f docker-compose.dev.yml up -d

Remember to change /c/Users/<your windows user path>/.nuget/packages, if you run it on Windows.

I will fix the readme for this project soon as soon as I finish to test it on coolstore-microservices project. Thank you for your interesting on this project
