根因分析

gRPC服务器未注册调用的RPC方法的处理程序，可能是由于缺少注册或服务名称错误。

English

The gRPC server does not have a handler registered for the invoked RPC method, possibly due to missing registration or incorrect service name.

解决方案

  1. 95% 成功率 Ensure the server registers the service with the correct generated code. 
    grpcServer := grpc.NewServer()
pb.RegisterGreeterServer(grpcServer, &myGreeterServer{})
  2. 90% 成功率 Verify the proto file and regenerate stubs if method was added recently. 
    protoc --go_out=. --go-grpc_out=. *.proto

无效尝试

常见但无效的做法:

  1. Restarting the server without changing code. 100% 失败

    The handler is still missing; restart doesn't add it.

  2. Checking client method name only, ignoring server registration. 90% 失败

    The server must register the method; client alone can't fix it.
