我是横杆上的一个笨蛋。 我正在尝试订阅一个主题,在python中使用autobahn和crossbar。你知道吗
crossbar url是“wss://*******.******.org/ws/”,主题是c*******d
没有信号主题,每个呼叫都指向此主题c*******d
我在那里找到了一些代码片段https://autobahn.readthedocs.io/en/latest/,并尝试对其进行修改。你知道吗
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])
我得到这个错误。好像什么都没有正常工作。你知道吗

如前所述,我是新到这一点,所以任何洞察上述将不胜感激!你知道吗
