【ASP.NETCore学习】远程过程调用gRPC使用

RPC是Remote Procedure Call简称，翻译过来是远程过程调用。它是一个进程间的通讯技术，基于Client-Server模式，让程序像调用本地方法一样使用，而无需去关系它细节如何实现。

上面是我的理解，怕理解有错或者表达不准确，下面引用***

*** a remote procedure call (RPC) is when a computer program causes a procedure (subroutine) to execute in a different address space (commonly on another computer on a shared network), which is coded as if it were a normal (local) procedure call, without the programmer explicitly coding the details for the remote interaction

网上找到一个图，比较形象描述RPC调用过程

什么时候需要RPC

dotnet tool install dotnet-grpc -g

syntax = "proto3";

option csharp_namespace = "gRPC.Services";

package sms;

// The greeting service definition.
service SmsSender {
  // Sends a greeting
  rpc SendSms (SmsRequest) returns (SmsResponse);
}

// The request message containing the user's name.
message SmsRequest {
  string tel = 1;
  string cOntent= 2;
}

// The response message containing the greetings.
message SmsResponse {
  int32 code = 1;
  string message = 2;
}

dotnet new grpc -n gRPC.Services

dotnet-grpc add-file ..\gRPC.Protos\*.proto -s Serve

public class SmsService : SmsSender.SmsSenderBase
{
    private readonly ILogger _logger;
    public SmsService(ILogger logger)
    {
        _logger = logger;
    }

    public override Task SendSms(SmsRequest request, ServerCallContext context)
    {
        return Task.FromResult(new SmsResponse
        {
            Code = 1,
            Message = "发送成功"
        });
    }
}

app.UseEndpoints(endpoints =>
{
    endpoints.MapGrpcService();
});

dotnet new console -n gRPC.Client

dotnet add package Google.Protobuf

dotnet-grpc add-file ..\gRPC.Protos\*.proto -s Client
