Kestrel gRPC

gRPC走http2协议，到目前我还没找到如何把gRPC server 部署在iis下。

现在只能走Kestrel。

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();

                    webBuilder.UseKestrel();
                    webBuilder.UseUrls("http://localhost:7777");
                    webBuilder.ConfigureKestrel(i =>
                    {
                        i.ConfigureEndpointDefaults(op => { op.Protocols = Microsoft.AspNetCore.Server.Kestrel.Core.HttpProtocols.Http2; });
                    });
                });

或者 appsettings.json 可以配置协议为http2：

  "Kestrel": {
    "Endpoints": {
      "Http": {
        "Url": "http://localhost:7777",
        "Protocols": "Http2"
      }
    }
  }

    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllers().AddJsonOptions(options =>
            {
                options.JsonSerializerOptions.Converters.Add(new DateTimeConverter());
                options.JsonSerializerOptions.Converters.Add(new DateTimeNullConverter());
            });

            services.AddGrpc();
            services.AddMagicOnion(i =>
            {
                i.IsReturnExceptionStackTraceInErrorDetail = true;
                i.SerializerOptions = MessagePackSerializerOptions.Standard.WithResolver(
                           MessagePack.Resolvers.ContractlessStandardResolverAllowPrivate.Instance);
                i.EnableCurrentContext = true;
            });
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseHttpsRedirection();

            app.UseRouting();

            //app.UseAuthorization();
            

            app.UseEndpoints(endpoints =>
            {
                //endpoints.MapControllers();
                endpoints.MapMagicOnionService();

            });
        }
    }

 客户端调用：

                AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);

                var channel = GrpcChannel.ForAddress("http://localhost:7777");
                
                var client = MagicOnionClient.Create<IUserSvc>(channel, MessagePackSerializerOptions.Standard.WithResolver(
                               MessagePack.Resolvers.ContractlessStandardResolverAllowPrivate.Instance));

                var users = await client.GetUsrs();
