Root Cause

The gRPC server does not register or implement the requested service, often due to missing stub registration or proto mismatch.

generic

中文

gRPC 服务器未注册或实现请求的服务，通常是由于缺少存根注册或 proto 不匹配。

Workarounds

  1. 90% success Register the service implementation on the server, e.g., in Python: `server.add_insecure_port('[::]:50051'); server.start()` after adding `add_MyServiceServicer_to_server(MyServiceServicer(), server)`. 
    Register the service implementation on the server, e.g., in Python: `server.add_insecure_port('[::]:50051'); server.start()` after adding `add_MyServiceServicer_to_server(MyServiceServicer(), server)`.
  2. 80% success Verify that the client and server use the exact same proto file version; regenerate stubs if mismatched.

中文步骤

  1. 在服务器上注册服务实现，例如在 Python 中：在添加 `add_MyServiceServicer_to_server(MyServiceServicer(), server)` 后使用 `server.add_insecure_port('[::]:50051'); server.start()`。
  2. 验证客户端和服务器使用完全相同的 proto 文件版本；如果不匹配则重新生成存根。

Dead Ends

Common approaches that don't work:

  1. Restarting the server without recompiling the service 95% fail

    The service registration is missing in the code; restart doesn't add it.

  2. Adding the service proto file to the client only 90% fail

    The server must implement the service; client-side proto doesn't help.
