前言
gRPC 是一种高性能、开源的远程过程调用（RPC）框架，它基于 Protocol Buffers（protobuf）定义服务，并使用 HTTP/2 协议进行通信。
新建项目
新建解决方案GrpcDemo
新建webapi项目GrpcServer作为grpc服务端项目
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;
}
编辑GrpcServer项目文件，添加
新建类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();
就是添加下面两行代码
builder.Services.AddGrpc();
app.MapGrpcService<GreeterService>();
新建grpc客户端项目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">
复制服务器端端的greeter.proto到客户端项目
编辑GrpcClient项目文件，加
编辑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改成你的服务器端运行端口
结果展示
运行服务器端
运行客户端
