hi, I got 'twisted.internet.defer.alreadycallederror' error back.
here is my code, what's wrong in it? thanks for help.
class snmpFactory:
def __init__(self, filename):
self.deferred = defer.Deferred()
def readValue(self):
vol = readValue(self.voltageIp, voltageOid)
temp = readValue(self.powerIp, temperatureOid)
self.deferred.callback((vol, temp))
self.deferred.addCallback(self.handleResult)
def handleResult(self, (vol, temp)):
slice = time.strftime("%H:%M:%S")
print slice, ' the voltage is %s\nthe temperature is %s' % (vol,
temp)
s = snmpFactory()
i = 1
while (i < 10):
reactor.callLater(5, s.readSnmpValue)
i += 1
time.sleep(10)
reactor.run()
