我试图用Python和autobahn连接到远程主机上的crossbar[Twisted]
我使用的是PubSub修改后的示例代码:
from __future__ import print_function
from os import environ
from twisted.internet import reactor
from twisted.internet.defer import inlineCallbacks
from autobahn.twisted.wamp import ApplicationSession, ApplicationRunner
class Component(ApplicationSession):
def __init__(self, config=None):
ApplicationSession.__init__(self, config)
print("component created")
def onConnect(self):
print("transport connected")
self.join(self.config.realm)
def onChallenge(self, challenge):
print("authentication challenge received")
@inlineCallbacks
def onJoin(self, details=None):
print("session attached")
self.received = 0
for x in range(1, 501):
sub = yield self.subscribe(self.on_event, u'com.myapp.topic{}'.format(x))
if x % 100 == 0:
print("Subscribed to {} topics".format(x))
def on_event(self, i=None):
print("Got event: {}".format(i))
self.received += 1
self.config.extra for configuration, etc. (see [A])
if self.received > self.config.extra['max_events']:
print("Received enough events; disconnecting.")
self.leave()
def onDisconnect(self):
print("disconnected")
if reactor.running:
reactor.stop()
if __name__ == '__main__':
runner = ApplicationRunner(
url=u"ws://localhost:8080/ws",
realm=u"realm1",
extra=dict(
max_events=5000, # [A] pass in additional configuration
),
)
print(runner.log)
runner.run(Component)
我在本地主机上运行crossbar的一个实例进行测试,当我访问它时,一切都正常。在
^{pr2}$但如果我尝试连接到其他主机,会发生两件事: 如果是安全端口:
2016-04-01T17:26:16+0000 component created
2016-04-01T17:26:16+0000 transport connected
(会话从不附加,程序挂起)
如果端口不安全:
2016-04-01T17:26:16+0000 component created
2016-04-01T17:26:16+0000 transport connected
2016-04-01T17:26:19+0000 disconnected
2016-04-01T17:26:19+0000 Main loop terminated.
(在连接会话之前,连接会自动将我踢出
我要连接的主机有8080作为安全端口,8081用于不安全端口。所以我改变的是:
url=u'ws://{hostname}:8080/ws', (or)
url=u'ws://{hostname}:8081/ws',
我想知道我是否遗漏了WAMP连接的一些明显的东西,或者这可能是我试图连接的crossbar实例上的配置问题。在
我通过在一个virtualenv上运行这个程序来解决了我的问题,它包含以下版本的autobahn和twisted:
我不知道为什么最新版本会这样,我只知道我上面的代码只能在那些版本上工作。在
