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
});
}
}
二、postman调用Grpc
输入grpc主机和port,不需要输入http、https,点击右侧下拉框,点击Use server reflection会自动反射Grpc服务接口,Invoke调试即可
