Server
.. code-block:: python
from grpcalchemy.orm import Message, StringField
from grpcalchemy import Server, Context, grpcmethod
class HelloMessage(Message):
text: str
class HelloService(Server):
@grpcmethod
def Hello(self, request: HelloMessage, context: Context) -> HelloMessage:
return HelloMessage(text=f'Hello {request.text}')
if __name__ == '__main__':
HelloService.run()
Then Using gRPC channel to connect the server:
.. code-block:: python
from grpc import insecure_channel
from protos.helloservice_pb2_grpc import HelloServiceStub
from protos.hellomessage_pb2 import HelloMessage
with insecure_channel("localhost:50051") as channel:
response = HelloServiceStub(channel).Hello(
HelloMessage(text="world")
)
