为什么我会收到此错误？这就是我如何调用流API.

import tweepy
import sys

creds = json.loads(open('credential.json').read())
tw_consumer_key = creds['tw_consumer_key']
tw_consumer_secret = creds['tw_consumer_secret']
tw_access_token = creds['tw_access_token']
tw_access_token_secret = creds['tw_access_token_secret']

try:
    auth = tweepy.OAuthHandler(tw_consumer_key,tw_consumer_secret)
    auth.set_access_token(tw_access_token,tw_access_token_secret)
    api = tweepy.API(auth)
except Exception:
    service = None
    api = None    

# Query terms
Q = "Better"

class CustomStreamListener(tweepy.StreamListener):
    def on_status(self,status):
        try:
            print "%s\n%s\n%s\n%s\n\n" % (status.text,status.author.screen_name,status.created_at,status.source,)
        except Exception,e:
            print >> sys.stderr,'Encountered Exception:',e
            pass

    def on_error(self,status_code):
        print >> sys.stderr,'Encountered error with status code:',status_code
        return True # Don't kill the stream

    def on_timeout(self):
        print >> sys.stderr,'Timeout...'
        return True # Don't kill the stream



class LiveStream(webapp2.RequestHandler):
    def get(self):
        streaming_api = tweepy.streaming.Stream(auth,CustomStreamListener(),timeout=60)
        self.response.out.write(streaming_api.filter(track=Q))

可能由GAE引起的不允许套接字,我不知道如何应用查询术语来获取特定的过滤流式推文.这部分代码的目的是获取指定关键字的实时流.如果有其他方法,请指导.
