gRPC 是一種高性能、開(kāi)源的遠(yuǎn)程過(guò)程調(diào)用（RPC）框架,它基于 Protocol Buffers（protobuf）定義服務(wù),并使用 HTTP/2 協(xié)議進(jìn)行通信,這篇文章主要介紹了在?ASP.NET?Core?中創(chuàng)建?gRPC?客戶(hù)端和服務(wù)器,需要的朋友可以參考下

前言

gRPC 是一種高性能、開(kāi)源的遠(yuǎn)程過(guò)程調(diào)用（RPC）框架，它基于 Protocol Buffers（protobuf）定義服務(wù)，并使用 HTTP/2 協(xié)議進(jìn)行通信。

新建項(xiàng)目

新建解決方案GrpcDemo

新建webapi項(xiàng)目GrpcServer作為grpc服務(wù)端項(xiàng)目

添加包

    <PackageReference Include="Grpc.AspNetCore" Version="2.67.0" />
    <PackageReference Include="Grpc.Tools" Version="2.67.0">

新建文本文件greeter.proto

syntax = "proto3";
option csharp_namespace = "GrpcServer";
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;
}

編輯GrpcServer項(xiàng)目文件，添加

新建類(lèi)GreeterService.cs

using Grpc.Core;
namespace GrpcServer
{
    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
            });
        }
    }
}

修改Program.cs

using GrpcServer;
var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
builder.Services.AddGrpc();
var app = builder.Build();
app.MapGrpcService<GreeterService>();
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}
app.UseHttpsRedirection();
app.UseAuthorization();
app.MapControllers();
app.Run();

就是添加下面兩行代碼

builder.Services.AddGrpc();
app.MapGrpcService<GreeterService>();

新建grpc客戶(hù)端項(xiàng)目GrpcClient

添加包

    <PackageReference Include="Google.Protobuf" Version="3.28.3" />
    <PackageReference Include="Grpc.Net.Client" Version="2.67.0" />
    <PackageReference Include="Grpc.Tools" Version="2.67.0">

復(fù)制服務(wù)器端端的greeter.proto到客戶(hù)端項(xiàng)目

編輯GrpcClient項(xiàng)目文件，加

編輯Program.cs文件

using Grpc.Net.Client;
using GrpcClient;
using var channel = GrpcChannel.ForAddress("https://localhost:7052");
var client = new Greeter.GreeterClient(channel);
var reply = await client.SayHelloAsync(
                  new HelloRequest { Name = "wxy" });
Console.WriteLine("Greeting: " + reply.Message);
Console.WriteLine("Press any key to exit...");
Console.ReadKey();

7052改成你的服務(wù)器端運(yùn)行端口

結(jié)果展示

運(yùn)行服務(wù)器端

運(yùn)行客戶(hù)端
