postman调用Grpc

环境：

.net6.0

一、准备

安装nuget：

Grpc.AspNetCore

Google.Protobuf

Grpc.Core.Api

Grpc.Tools

Grpc.AspNetCore.Server.Reflection

Program.cs：

 public class Program
 {
     public static void Main(string[] args)
     {
         var builder = WebApplication.CreateBuilder(args);

         // Additional configuration is required to successfully run gRPC on macOS.
         // For instructions on how to configure Kestrel and gRPC clients on macOS, visit https://go.microsoft.com/fwlink/?linkid=2099682

         // Add services to the container.
         builder.Services.AddGrpc();

         builder.Services.AddGrpcReflection();//添加gRPC反射

         var app = builder.Build();

         IWebHostEnvironment env = app.Environment;
         // Configure the HTTP request pipeline.
         app.MapGrpcService<GreeterService>();

         if (env.IsDevelopment())
         {
             //映射gRPC反射服务
             app.MapGrpcReflectionService();
         }

         app.MapGet("/", () => "Communication with gRPC endpoints must be made through a gRPC client. To learn how to create a client, visit: https://go.microsoft.com/fwlink/?linkid=2086909");

         app.Run();
     }
 }

greet.proto：

syntax = "proto3";

option csharp_namespace = "Grpc.Common";

package greet;

// The greeting service definition.
service Greeter {
  // Sends a greeting
  rpc SayHello (HelloRequest) returns (HelloReply);
}

// The request message containing the user's name.
message HelloRequest {
  string name = 1;
}

// The response message containing the greetings.
message HelloReply {
  string message = 1;
}

GreeterService ：

    public class GreeterService : Greeter.GreeterBase
    {
        private readonly ILogger<GreeterService> _logger;
        public GreeterService(ILogger<GreeterService> logger)
        {
            _logger = logger;
        }

        public override Task<HelloReply> SayHello(HelloRequest request, ServerCallContext context)
        {
            return Task.FromResult(new HelloReply
            {
                Message = "Hello " + request.Name
            });
        }
    }
