问题 I have a autobahn twisted websocket running in python which is working in a dev vm correctly but I have been unable to get working when the server is running in openshift. Here is the shortened code which works for me in a vm. from autobahn.twisted.websocket import WebSocketServerProtocol, WebSocketServerFactory, listenWS from autobahn.twisted.resource import WebSocketResource class MyServerProtocol(WebSocketServerProtocol): def onConnect(self, request): stuff... def onOpen(self): stuff...

问题 I want to call sendMessage method from outside of MyServerProtocol class and send a message to the server. The answare is very similar to this but i need to use asyncio instead of twisted . Cane someone suggest me a solution? An example derived from this would also be appreciated Thanks. 回答1: The call_soon_threadsafe function of event loop is meant for this. from autobahn.asyncio.websocket import WebSocketServerProtocol, \ WebSocketServerFactory class MyServerProtocol(WebSocketServerProtocol)

问题 Normally, a publish-subscribe pattern is about fetching content updates. But how do subscribers get initial content that was there before they subscribed for updates? I'm using publish-subscribe examples within autobahn framework for my application. The publisher backend publishes a position of the robotic joint when the joint moves. The client frontend subscribes to the topic sometimes later. Due to the nature of the data, the initial value of the "topic" on the client is just as important
