ASP.NET Core gRPC JSON transcoding throws InvalidOperationException

问题

我有一个基本的应用程序，并使用了 在 ASP.NET Core 中使用 gRPC JSON 转码 文章来集成 gRPC JSON 转码。然而，当我尝试运行我的应用程序时，它给了我一个错误消息：

  1. System.InvalidOperationException: 绑定 gRPC 服务时出错 'SomeGrpcService'。
  2.  ---> System.Reflection.TargetInvocationException: 调用目标的异常已被抛出。
  3.  ---> System.InvalidOperationException: 存储的扩展值的类型为 'Google.Api.HttpRule, Shared, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'。这与请求的类型不同 'Google.Api.HttpRule, Google.Api.CommonProtos, Version=2.5.0.0,Culture=neutral, PublicKeyToken=3ec5ea7f18953e47'。
  4.    在 Google.Protobuf.ExtensionSet.Get[TTarget,TValue](ExtensionSet`1& set, Extension`2 extension)
  5.    在 Google.Protobuf.Reflection.MethodOptions.GetExtension[TValue](Extension`2 extension)
  6.    在 Grpc.Shared.ServiceDescriptorHelpers.TryGetHttpRule(MethodDescriptor methodDescriptor, HttpRule& httpRule)
  7.    在 Microsoft.AspNetCore.Grpc.JsonTranscoding.Internal.Binding.JsonTranscodingProviderServiceBinder`1.AddMethod[TRequest,TResponse](Method`2 method, UnaryServerMethod`2 handler)
  8.    在 WBD.Bolt.OneTimePassword.gRPC.API.PhoneOtpService.BindService(ServiceBinderBase serviceBinder, PhoneOtpServiceBase serviceImpl) in /.../obj/Debug/net7.0/SomeGrpc.cs:line 187
  9.    在 InvokeStub_PhoneOtpService.BindService(Object, Object, IntPtr*)
  10.    在 System.Reflection.MethodInvoker.Invoke(Object obj, IntPtr* args, BindingFlags invokeAttr)
  11.    --- 内部异常堆栈跟踪的结尾 ---
  12.    在 System.Reflection.MethodInvoker.Invoke(Object obj, IntPtr* args, BindingFlags invokeAttr)
  13.    在 System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
  14.    在 Microsoft.AspNetCore.Grpc.JsonTranscoding.Internal.Binding.JsonTranscodingServiceMethodProvider`1.OnServiceMethodDiscovery(ServiceMethodProviderContext`1 context)
  15.    --- 内部异常堆栈跟踪的结尾 ---
  16.    在 Microsoft.AspNetCore.Grpc.JsonTranscoding.Internal.Binding.JsonTranscodingServiceMethodProvider`1.OnServiceMethodDiscovery(ServiceMethodProviderContext`1 context)
  17.    在 Grpc.AspNetCore.Server.Model.Internal.ServiceRouteBuilder`1.Build(IEndpointRouteBuilder endpointRouteBuilder)
  18.    在 Microsoft.AspNetCore.Builder.GrpcEndpointRouteBuilderExtensions.MapGrpcService[TService](IEndpointRouteBuilder builder)
  19.    在 SomeApplication.Program.Main(String[] args) in /.../SomeApplication/Program.cs:line 97

我的设置如下：
我在 *.csproj 文件中有以下行：

  1. <ItemGroup>
  2.       <Protobuf Include="Protos\**\*.proto" ProtoRoot="Protos\" GrpcServices="Both" />
  3. </ItemGroup>

文件夹结构如下：

  1. Protos
  2.   google
  3.     api
  4.       annotations.proto
  5.       http.proto
  6.   Some.proto

我相信主要问题是：

  1. 存储的扩展值的类型为 'Google.Api.HttpRule, Shared, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'。这与请求的类型不同 'Google.Api.HttpRule, Google.Api.CommonProtos, Version=2.5.0.0,Culture=neutral, PublicKeyToken=3ec5ea7f18953e47'。

我正在使用 Microsoft.AspNetCore.Grpc.JsonTranscoding 版本 7.0.9。

有人能提供上述问题的解决方案吗？

I have a basic application and used the gRPC JSON transcoding in ASP.NET Core article to incorporate gRPC JSON transcoding. However, when I try to run my application, it gives me an error message:

  1. System.InvalidOperationException: Error binding gRPC service &#39;SomeGrpcService&#39;.
  2.  ---&gt; System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
  3.  ---&gt; System.InvalidOperationException: The stored extension value has a type of &#39;Google.Api.HttpRule, Shared, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null&#39;. This a different from the requested type of &#39;Google.Api.HttpRule, Google.Api.CommonProtos, Version=2.5.0.0,Culture=neutral, PublicKeyToken=3ec5ea7f18953e47&#39;.

  19.    at SomeApplication.Program.Main(String[] args) in /.../SomeApplication/Program.cs:line 97

My setup is the following:
I have the following line in the *.csproj file:

  1. &lt;ItemGroup&gt;
  2.       &lt;Protobuf Include=&quot;Protos\**\*.proto&quot; ProtoRoot=&quot;Protos\&quot; GrpcServices=&quot;Both&quot; /&gt;
  3. &lt;/ItemGroup&gt;

and folder structure is:

  1. Protos
  2.   google
  3.     api
  4.       annotations.proto
  5.       http.proto
  6.   Some.proto

I believe the main issue is:

  1. The stored extension value has a type of &#39;Google.Api.HttpRule, Shared, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null&#39;. 
  2. This a different from the requested type of &#39;Google.Api.HttpRule, Google.Api.CommonProtos, Version=2.5.0.0,Culture=neutral, PublicKeyToken=3ec5ea7f18953e47&#39;.

and I am using Microsoft.AspNetCore.Grpc.JsonTranscoding version 7.0.9.

Can someone offer a solution to the problem mentioned above?

你必须像这样更改你的目录：

  1.   google
  2.     api
  3.       annotations.proto
  4.       http.proto
  5.   Protos
  6.     Some.proto

项目目录

英文:

You must change your directory like this:

  1.   google
  2.     api
  3.       annotations.proto
  4.       http.proto
  5.   Protos
  6.     Some.proto

以下更改已解决了我的问题：

更新 *.csproj 文件：

  1. <ItemGroup>
  2.     <Protobuf Include="Protos\Some.proto" ProtoRoot="Protos\" GrpcServices="Both" />
  3. </ItemGroup>

并将 Google.Api.CommonProtos 库添加到项目中。

英文:

The following changes are fixed the issue for me:

update *.csproj file:

  1. &lt;ItemGroup&gt;
  2.       &lt;Protobuf Include=&quot;Protos\Some.proto&quot; ProtoRoot=&quot;Protos\&quot; GrpcServices=&quot;Both&quot; /&gt;
  3. &lt;/ItemGroup&gt;

and added the Google.Api.CommonProtos library to the project.
