我希望在MongoDB中存储x#推文之后,Tweepy Streaming API会停止推文。
我在类中尝试了IF和WHILE语句,使用计数器进行了定义,但是无法让它停在某个X量。对我来说,这真是一个真正的头脑。我在这里找到了这个链接:https://groups.google.com/forum/#!topic/tweepy/5IGlu2Qiug4但是我复制这个的努力失败了。它总是告诉我 init 需要一个额外的参数。我相信我们的Tweepy auth设置不同,所以它不是苹果到苹果。
有什么想法吗?
from tweepy.streaming import StreamListener
from tweepy import OAuthHandler
from tweepy import Stream
import json, time, sys
import tweepy
auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET)
auth.set_access_token(OAUTH_TOKEN, OAUTH_TOKEN_SECRET)
class StdOutListener(StreamListener):
def on_status(self, status):
text = status.text
created = status.created_at
record = {'Text': text, 'Created At': created}
print record #See Tweepy documentation to learn how to access other fields
collection.insert(record)
def on_error(self, status):
print 'Error on status', status
def on_limit(self, status):
print 'Limit threshold exceeded', status
def on_timeout(self, status):
print 'Stream disconnected; continuing...'
stream = Stream(auth, StdOutListener())
stream.filter(track=['tv'])

您需要在__init__
内的班级内添加一个计数器,然后在on_status
内增加一个计数器。然后当计数器低于20时,它会将记录插入集合中。这可以如下所示完成:
def __init__(self, api=None):
super(StdOutListener, self).__init__()
self.num_tweets = 0
def on_status(self, status):
record = {'Text': status.text, 'Created At': status.created_at}
print record #See Tweepy documentation to learn how to access other fields
self.num_tweets += 1
if self.num_tweets < 20:
collection.insert(record)
return True
else:
return False
