[英]How to fire a deferred in Twisted?
I'm working with twisted. 我正在努力工作。 I'm a little bit confused about using deferred objects.
我对使用延迟对象有点困惑。 I see me correct result in this deferred but I can't work with it.
我看到这个推迟的正确结果,但我无法使用它。
For example 例如
def hello(defer):
print(defer)
Just printest me 只是打电话给我
Deferred at 0x24dv5f5 current result: 44
延迟到0x24dv5f5当前结果:44
How can I access this result? 如何访问此结果?
Update 更新
This is my code where I try to fire the deferred 这是我的代码,我试图解雇延迟
def handleLoginFailed(self, sid, args):
d = defer.Deferred()
d.callback(sid)
def writeLoginFailed(sid, args):
print("sid:", sid)
self.simpleQuery(
"""
INSERT INTO auth
(session, success, username, password, timestamp)
VALUES (%s, %s, %s, %s, FROM_UNIXTIME(%s))
""",
(sid, 0, args['username'],
args['password'], self.nowUnix()))
d.addCallback(writeLoginFailed(sid, args))
d = Deferred()
d.callback("the result")
def handleTheResult(result):
print "The Deferred fired, its result is:", result
d.addCallback(handleTheResult)
