使用gRPC实现客户端和服务端通信

参考文档:

基于C#的GRPC

1 创建项目和文件夹

GrpcClientDemoGrpcServerDemoProtos解决方案和文件夹

1.1 添加nuget依赖

客户端和服务器都要有依赖和gRPC_Objects文件夹

 <ItemGroup><PackageReference Include="Google.Protobuf" Version="3.25.2" /><PackageReference Include="Grpc" Version="2.46.6" /><PackageReference Include="Grpc.Core" Version="2.46.6" /><PackageReference Include="Grpc.Tools" Version="2.46.6"><PrivateAssets>all</PrivateAssets><IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets></PackageReference></ItemGroup><ItemGroup><Protobuf Include="../Protos/*.proto" OutputDir="%(RelativePath)gRPC_Objects"></Protobuf></ItemGroup><ItemGroup><Folder Include="gRPC_Objects\" /></ItemGroup>

1.2 添加hello.proto

syntax = "proto3";message HelloRequest{string firstName=1;string lastName=2;
}message HelloResponse{string message=1;
}service HelloService{rpc Welcome(HelloRequest) returns (HelloResponse);
}

编译会自动生成代码

2 创建服务端代码

GServices/HelloServiceImpl.cs

using Grpc.Core;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using static HelloService;namespace GrpcServerDemo.GServices
{public class HelloServiceImpl:HelloServiceBase{public override Task<HelloResponse> Welcome(HelloRequest request, ServerCallContext context){var message = $"你好 {request.FirstName} {request.LastName}";return Task.FromResult(new HelloResponse { Message = message });                          //return base.Welcome(request, context);}}
}

Program.cs

using Grpc.Core;
using GrpcServerDemo.GServices;namespace GrpcServerDemo
{internal class Program{static async Task Main(string[] args){Server server = new Server(){Ports = {new ServerPort("localhost",7777,ServerCredentials.Insecure)},Services = {HelloService.BindService(new HelloServiceImpl())}               };try{server.Start();Console.WriteLine($"server is listening to port 7777");Console.ReadKey();}catch (Exception ex){Console.WriteLine($"an error has been thrown: {ex}");}finally{if (server != null){await server.ShutdownAsync();}}}}
}

3 创建客户端代码

Program.cs

using Grpc.Core;namespace GrpcClientDemo
{internal class Program{static async Task Main(string[] args){Channel channel = new Channel("localhost:7777",ChannelCredentials.Insecure);try{await  channel.ConnectAsync();Console.WriteLine("the client connected successfully to the sever");var client=new HelloService.HelloServiceClient(channel);HelloResponse helloResponse = await client.WelcomeAsync(new HelloRequest{FirstName="xie",LastName="万能"});Console.WriteLine("接受到数据："+helloResponse.Message);Console.ReadKey();}catch (Exception ex){Console.WriteLine($"an error has been thrown: {ex}");}finally{if(channel != null){await channel.ShutdownAsync();}}}}
}
