流式 API 是您想要的。我使用了一个名为 tweetstream 的库。这是我的基本聆听功能:
def retrieve_tweets(numtweets=10, *args):
"""
This function optionally takes one or more arguments as keywords to filter tweets.
It iterates through tweets from the stream that meet the given criteria and sends them
to the database population function on a per-instance basis, so as to avoid disaster
if the stream is disconnected.
Both SampleStream and FilterStream methods access Twitter's stream of status elements.
For status element documentation, (including proper arguments for tweet['arg'] as seen
below) see https://dev.twitter.com/docs/api/1/get/statuses/show/%3Aid.
"""
filters = []
for key in args:
filters.append(str(key))
if len(filters) == 0:
stream = tweetstream.SampleStream(username, password)
else:
stream = tweetstream.FilterStream(username, password, track=filters)
try:
count = 0
while count < numtweets:
for tweet in stream:
# a check is needed on text as some "tweets" are actually just API operations
# the language selection doesn't really work but it's better than nothing(?)
if tweet.get('text') and tweet['user']['lang'] == 'en':
if tweet['retweet_count'] == 0:
# bundle up the features I want and send them to the db population function
bundle = (tweet['id'], tweet['user']['screen_name'], tweet['retweet_count'], tweet['text'])
db_initpop(bundle)
break
else:
# a RT has a different structure. This bundles the original tweet. Getting the
# retweets comes later, after the stream is de-accessed.
bundle = (tweet['retweeted_status']['id'], tweet['retweeted_status']['user']['screen_name'], \
tweet['retweet_count'], tweet['retweeted_status']['text'])
db_initpop(bundle)
break
count += 1
except tweetstream.ConnectionError, e:
print 'Disconnected from Twitter at '+time.strftime("%d %b %Y %H:%M:%S", time.localtime()) \
+'. Reason: ', e.reason
我有一段时间没看,但我很确定这个库只是在访问示例流(而不是 firehose)。HTH。
编辑添加:您说您想要“完整的直播”,也就是消防软管。这在财政和技术上都很昂贵,而且只有非常大的公司才能拥有它。查看文档,您会发现该示例基本上具有代表性。
