eoq3autobahnws - Websocket domain client and host using autobahn

A domain server makes a local domain accessible via a WS port.

A domain host connects to a remote domain using WS.

client and server are based on autobahn: https://autobahn.readthedocs.io/en/latest/index.html

Usage

Define serialization and timeouts

config = Config()
config.remoteCmdTxSerializer = "TXT" #or JSO
config.remoteCmdRxSerializers = ["TXT","JSO"] #or e.g. ["TXT"]
config.remoteFrmTxSerializer = "TXT" #or JSO
config.remoteFrmRxSerializer = "TXT" #or JSO
config.connectTimeout = 40

Host

Imports:

from eoq3autobahnws.autobahnwsdomainhost import AutobahnWsDomainHost

Create an SSL factory (optional):

def ServerSslFactory(sslFactoryArgs:dict):
    return CreateSelfSignedServerSslContext("ssl/certificate.pem", "ssl/key.pem", "ILS-admin")

Creating a TCP host domain that provides acces to another domain "localDomain", e.g. DomainWithMdb:

server = AutobahnWsDomainHost(localDomain, True, '127.0.0.1', 5141, nWorkers=N_THREADS, config=config) #no ssh

server = AutobahnWsDomainHost(localDomain, True, '127.0.0.1', 5141, sslContextFactory=ServerSslFactory, nWorkers=N_THREADS, config=config) #with ssh

Client

Imports:

from eoq3autobahnws.autobahnwsdomainclient import AutobahnWsDomainClient
from eoq3autobahnws.util.ssl import CreateClientSslContextForSelfSignedServerCert

Create an SSL factory (optional):

def ClientSslFactory(domainFactoryArgs:dict): 
    return CreateClientSslContextForSelfSignedServerCert("ssl/certificate.pem")

Connecting to a remote domain:

domain = AutobahnWsDomainClient('127.0.0.1',5141) #no ssl

domain = AutobahnWsDomainClient('127.0.0.1',5141,sslContextFactory=ClientSslFactory) #with ssl
