What are my options for integrating Python with SignalR?
The Python code is a part of large 3rd party product, not a matter of language preference. SignalR server provides subscriptions to existing .NET products.
We would like to reuse .NET SignalR server with Python.

I can think of a few ways and they are all theoretical (and probably bad ideas to begin with):
- IPC - host the python app and the signalr app as different processes and somehow pipe information back and forth using some kind of ipc mechanism (named pipes, tcp, something else).
- Use IronPython (which probably isn't really an option).
- Port a lightweight verison of SignalR to python (https://github.com/davidfowl/SignalR.Lite). Probably won't work the same way but maybe you don't need all the features.
Or you can hope to find a library in python that does something similar.
回答2:
There is a SignalR client available on the python package index named "signalr-client" which supports some basic SignalR functionality Source
It is compatible with Python v2 and v3.
Functionality supported includes:
- Connecting to SignalR Hub
- Invoking SignalR Method
- Event handler to process SignalR Notifications
It requires the following modules installed via pip:
- gevent
- sseclient
- websocket-client
Sample usage as per link:
#create a connection
connection = Connection(url, session)
#start a connection
connection.start()
#add a handler to process notifications to the connection
connection.handlers += lambda data: print 'Connection: new notification.', data
#get chat hub
chat_hub = connection.hub('chat')
#create new chat message handler
def message_received(message):
print 'Hub: New message.', message
#receive new chat messages from the hub
chat_hub.client.on('message_received', message_received)
#send a new message to the hub
chat_hub.server.invoke('send_message', 'Hello!')
#do not receive new messages
chat_hub.client.off('message_received', message_received)
#close the connection
connection.close()
