Cryptomood b2b client - python

Client example

  1. Ensure that you have x509 .pem file (cert.pem). You won't be able to access the server without it

  2. Make sure you have Python 2.7 or Python 3.4 or higher

  3. Ensure you have pip version 9.0.1 or higher python -m pip install --upgrade pip

  4. Install gRPC and gRPC tools:

    python -m pip install grpcio
    python -m pip install grpcio-tools
  5. Generate types python -m grpc_tools.protoc -I../ --python_out=. --grpc_python_out=. ../types.proto

    Steps 3 is optional, because this directory already contains prepared and files

  6. Create credencials and join channel. You have to provide valid path to .pem file(from 1. step). and valid host address.

    creds = grpc.ssl_channel_credentials(open(PATH_TO_CERT_FILE, 'rb').read())
    channel = grpc.secure_channel(SERVER_ADDRESS, creds)
  7. Initialize the MessagesProxy service.

    stub = types_pb2_grpc.MessagesProxyStub(channel)
  8. Subscribe to required stream and listen to incoming data

    tweet_stream = stub.SubscribeTweet(empty_pb2.Empty())
    for tweet in tweet_stream:

For full example, see file in this directory. For additional resources, see the grpc library

You can’t perform that action at this time.
