Dapr .Net SDK 问题与 InvokeMethodGrpcAsync() gRPC 调用

如何解决Dapr .Net SDK 问题与 InvokeMethodGrpcAsync() gRPC 调用

我在 Dapr 中启动了一个具有 gRPC 服务的应用程序。 使用 ID MyGrpcApi001 启动 Dapr。 HTTP 端口：55319。gRPC 端口：55320

我使用以下命令启动它：

dapr run --app-id MyGrpcApi001 --app-protocol grpc --app-port 5000 -- dotnet run

原型：

Syntax = "proto3";

import "google/protobuf/empty.proto";

option csharp_namespace = "MyGrpcService";

package greet;

// The greeting service deFinition.
service Greeter {
  // Sends a greeting
  rpc SayHello (HelloRequest) returns (HelloReply);
  rpc Test (google.protobuf.Empty) returns (google.protobuf.Empty);
}

// The request message containing the user's name.
message HelloRequest {
  string name = 1;
}

// The response message containing the greetings.
message HelloReply {
  string message = 1;
}

我有一个客户端，它有 2 个使用 gRPC 连接到服务的方法

• 通过自动生成的客户端直接调用服务
• 另一个通过 dapr sidecar gRPC 端口

    class Program
    {
        private static string LOCAL_ADDRESS = @"http://localhost:5000";
        private static string DAPR_ADDRESS = $"http://localhost:55320";

        static async Task Main(string[] args)
        {
            await CallToLocalHost().ConfigureAwait(false); // runs OK
            await CallWithClient().ConfigureAwait(false); // exception: Service is unimplemented
        }

        private static async Task CallToLocalHost()
        {
            using var channel = GrpcChannel.ForAddress(LOCAL_ADDRESS);
            var cl = new MyGrpcService.Greeter.GreeterClient(channel);
            MyGrpcService.HelloReply response = await cl.SayHelloAsync(new MyGrpcService.HelloRequest { Name = "ThinkPad" });
            Console.WriteLine(response.Message);
        }

        private static async Task CallWithClient()
        {
            using DaprClient client = new DaprClientBuilder()
                     .UseGrpcEndpoint(DAPR_ADDRESS)
                     .Build();

            var request = new MyGrpcService.HelloRequest { Name = "ThinkPad" };
            var result = await client.InvokeMethodGrpcAsync<MyGrpcService.HelloRequest,MyGrpcService.HelloReply>("MyGrpcApi001","SayHello",request).ConfigureAwait(false);
        }
    }

第二种方法好像不行，所以直接调用可以，但是sidecar好像没有找到服务。以下是两者的日志：

正在运行的服务的日志：

第一种方法OK：

== APP == info: Microsoft.AspNetCore.Hosting.Diagnostics[1]
== APP ==       Request starting HTTP/2 POST http://localhost:5000/greet.Greeter/SayHello application/grpc -

第二种方法错误：

第二个似乎包含错误的 URL，其中包含 /dapr.proto.runtime. ...

我在这里做错了什么？是 dapr 运行命令错误，还是我的 InvokeMethodGrpcAsync 方法参数错误？

由于我可以通过自动生成的客户端直接运行方法，我认为服务器工作正常，是dapr没有找到服务和/或方法。

有什么想法吗？

谢谢！
