如何在Grpc / Protobuf中进行路由和避免反序列化？

import grpc

# 自定义拦截器
class MyInterceptor(grpc.ServerInterceptor):
    def intercept_service(self, continuation, handler_call_details):
        # 根据handler_call_details中的信息进行路由逻辑
        if handler_call_details.method == '/service1.Method1':
            # 路由到处理逻辑1
            return handler1
        elif handler_call_details.method == '/service2.Method2':
            # 路由到处理逻辑2
            return handler2
        else:
            # 默认路由到原始的处理逻辑
            return continuation(handler_call_details)

# gRPC服务器
server = grpc.server(interceptors=[MyInterceptor()])

# 注册服务
service1_pb2_grpc.add_Service1Servicer_to_server(Service1Servicer(), server)
service2_pb2_grpc.add_Service2Servicer_to_server(Service2Servicer(), server)

# 启动服务器
server.add_insecure_port('[::]:50051')
server.start()
