alarm action with senlin webhook

[Chiawei Xie]

aodh version: queens

Used aodh create alarm, and alarm action was senlin cluster scale out webhook,
The webhook was:
http://10.50.2.4:8780/v1/webhooks/20d6d35b-0cb6-482e-bfd6-3fb0d943e914/trigger?V=1&count=2

Created alarm with url .

when alarm is trigger, check aodh-notifier log, got some message:

INFO aodh.notifier.rest [-]
Notifying alarm cpu-high with severity low from insufficient data to alarm with action
SplitResult(scheme=u'http', netloc=u'10.50.2.4:8780', path=u'/v1/webhooks/20d6d35b-0cb6-482e-bfd6-3fb0d943e914/trigger', query=u'V=1&count=2', fragment='')

INFO aodh.notifier.rest [-] Notifying alarm gets response: 400 Bad Request.

It looks like called webhook but got 400 status response.

But used curl command:
curl -X POST http://10.50.2.4:8780/v1/webhooks/20d6d35b-0cb6-482e-bfd6-3fb0d943e914/trigger?V=1&count=2

It worked to scale out my senlin cluster,

Why aodh called webhook failed?
