[英]Authentication to use for user notifications using Crossbar/Autobahn?
[英]subscribe to a topic in python on crossbar autobahn
我是橫梁的菜鳥。 我正在嘗試使用 python 中的高速公路和橫桿訂閱主題。
橫桿 url 為“wss://******.******.org/ws/”,主題為 c******d。
沒有信號主題,每個電話都轉到這個主題c******d。
我在那里找到了一些代碼https://autobahn.readthedocs.io/en/latest/並嘗試對其進行調整。
from autobahn.twisted.component import Component
from twisted.internet.defer import inlineCallbacks
from autobahn.twisted.component import Component
from autobahn.twisted.component import run
#component with my crossbar url :
component = Component(
transports=u"wss://******.******.org/ws/",
realm=u"realm1",
)
@component.on_join
@inlineCallbacks
def joined(session,details):
print("session ready")
def oncounter(count):
print("event received: {0}", count)
try:
yield session.subscribe(oncounter, u'c******d') #here my topic
print("subscribed to topic")
except Exception as e:
print("could not subscribe to topic: {0}".format(e))
if __name__ == "__main__":
run([component])
我收到這個錯誤。 似乎沒有什么工作正常。

如前所述,我對此並不陌生,因此將不勝感激任何有關上述內容的見解!
我認為你想要做的是:
import sys
import asyncio
from autobahn.asyncio.wamp import ApplicationSession, ApplicationRunner
import autobahn.wamp
class Component(ApplicationSession):
"""
An application component that subscribe to a topic
and print messages
"""
async def onJoin(self, details):
def onmessage(*args, **kwargs):
print ("message received kwargs= "+str(kwargs))
await self.subscribe(onmessage, "c******d")
def onDisconnect(self):
asyncio.get_event_loop().stop()
if __name__ == '__main__':
url = u"wss://************.org/ws/"
realm = u"realm1"
runner = ApplicationRunner(url, realm)
runner.run(Component,'debug')
