asp.net core grpc快速入门

环境

.net 8
vs2022

创建 gRPC 服务器

一定要勾选Https

安装Nuget包

<PackageReference Include="Google.Protobuf" Version="3.28.2" />
<PackageReference Include="Grpc.AspNetCore" Version="2.66.0" />
<PackageReference Include="Grpc.Net.Client" Version="2.66.0" />
<PackageReference Include="Grpc.Tools" Version="2.66.0"><PrivateAssets>all</PrivateAssets><IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
</PackageReference>

新建Protos文件夹，该文件下新建greet.proto

syntax = "proto3";service Greeter {rpc SayHello (HelloRequest) returns (HelloReply);
}message HelloRequest {string name = 1;
}message HelloReply {string message = 1;
}

添加编译

<ItemGroup><Protobuf Include="Protos\greet.proto" GrpcServices="Server" />
</ItemGroup>

新建Service文件夹，该文件夹下新建GreeterService

using Grpc.Core;namespace GrpcServer01.Service
{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){_logger.LogInformation("Saying hello to {Name}", request.Name);return Task.FromResult(new HelloReply{Message = "Hello " + request.Name});}}
}

修改Program.cs

using GrpcServer01.Service;namespace GrpcServer01
{public class Program{public static void Main(string[] args){var builder = WebApplication.CreateBuilder(args);//新增代码在这builder.Services.AddGrpc();var app = builder.Build();//新增代码在这app.MapGrpcService<GreeterService>();app.MapGet("/", () => "Hello World!");app.Run();}}
}

启动项目访问https://localhost:7006/

服务端创建成功

创建grpc客户端

安装nuget包

<ItemGroup><PackageReference Include="Google.Protobuf" Version="3.28.2" /><PackageReference Include="Grpc.Net.Client" Version="2.66.0" /><PackageReference Include="Grpc.Tools" Version="2.66.0"><PrivateAssets>all</PrivateAssets><IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets></PackageReference>
</ItemGroup>

复制服务端Protos\greet.proto到客户端

<ItemGroup><Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
</ItemGroup>

修改Program.cs

internal class Program
{static async Task Main(string[] args){using var channel = GrpcChannel.ForAddress("https://localhost:7006");var client = new Greeter.GreeterClient(channel);var reply = await client.SayHelloAsync(new HelloRequest { Name = "GreeterClient" });Console.WriteLine("Greeting: " + reply.Message);Console.WriteLine("Press any key to exit...");Console.ReadKey();}
}

客户端

服务端
