Provide a POST example

[profnimrod]

I having trouble getting a POST example to work for a custom object. The proto looks like:

rpc registerTerminal(RegisterTerminalRequest) returns (RegisterTerminalResponse) {
		option (google.api.http) = {
		  post: "ks/api/registerterminal",
		  body: "*"
		};
	  }

and the corresponding service override method looks like:

public class TerminalGatewayHighPriorityService : TerminalGatewayHighPriorityAPI.TerminalGatewayHighPriorityAPIBase
    {
        private readonly ILogger _logger;

        public TerminalGatewayHighPriorityService(ILoggerFactory loggerFactory)
        {
            _logger = loggerFactory.CreateLogger<TerminalGatewayHighPriorityService>();
        }

        public override Task<RegisterTerminalResponse> registerTerminal(RegisterTerminalRequest request, ServerCallContext context)
        {
            _logger.LogInformation($"Processing terminal registration request {request.TerminalId}");
            return Task.FromResult(new RegisterTerminalResponse());
        }
    }

Any ideas on what I'm doing wrong?

That isn't supported directly. You can use grpc-gateway, or track this issue for how to do it directly in .NET - #167

Thanks. I'm aware of grpc-gateway, but I'm working with .NET Core, not Go. Just to confirm, you're saying that the only supported HTTP verb with this library (GrpcHttpApi) is "GET"? The issue you suggest I track points to https://github.com/aspnet/AspLabs/tree/master/src/GrpcHttpApi which is what my initial post is referring to. Is supporting other verbs on the near-term roadmap for that library?

[JamesNK]

It supports all verbs. Why do you think it only supports GET?

[profnimrod]

Because I asked for an example with POST and you said "that isn't directly supported"... We might be talking passed each other. My question is concerned with the GrpcHttpApi library you pointed me to last week, which I have been trying to get to grips with.

[JamesNK]

Ok. It isn't directly supported in the publicly released and supported Grpc.AspNetCore framework. Experimental support is in GrpcHttpApi.

[profnimrod]

Thanks for the clarification. So back to my original query: how is POST done with GrpcHttpApi. I'm having trouble getting it working and a simple example would probably be sufficient to get me on the right track.

FYI The link for feedback at the bottom of https://github.com/aspnet/AspLabs/tree/master/src/GrpcHttpApi points to the transcoding issue you mentioned above. It was not clear to me whether you're expecting all feedback for GrpcHttpApi to be posted to that single issue, or to the grpc-dotnet issues in general. Apols if I've misinterpreted the intention.
