tweepy Streaming API：全文

Question

我正在使用tweepy流API来获取包含特定主题标签的推文。我面临的问题是我无法从Streaming API中提取推文的全文。只有140个字符可用，之后会被截断。

这是代码：

auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET)
auth.set_access_token(ACCESS_TOKEN, ACCESS_TOKEN_SECRET)
api = tweepy.API(auth)

def analyze_status(text):

if 'RT' in text[0:3]:
    return True
else:
    return False

class MyStreamListener(tweepy.StreamListener):

def on_status(self, status):

if not analyze_status(status.text) :

    with open('fetched_tweets.txt','a') as tf:
        tf.write(status.text.encode('utf-8') + '\n\n')

    print(status.text)

def on_error(self, status):
print("Error Code : " + status)

def test_rate_limit(api, wait=True, buffer=.1):
    """
    Tests whether the rate limit of the last request has been reached.
    :param api: The `tweepy` api instance.
    :param wait: A flag indicating whether to wait for the rate limit reset
             if the rate limit has been reached.
    :param buffer: A buffer time in seconds that is added on to the waiting
               time as an extra safety margin.
    :return: True if it is ok to proceed with the next request. False otherwise.
    """
    #Get the number of remaining requests
    remaining = int(api.last_response.getheader('x-rate-limit-remaining'))
    #Check if we have reached the limit
    if remaining == 0:
    limit = int(api.last_response.getheader('x-rate-limit-limit'))
    reset = int(api.last_response.getheader('x-rate-limit-reset'))
    #Parse the UTC time
    reset = datetime.fromtimestamp(reset)
    #Let the user know we have reached the rate limit
    print "0 of {} requests remaining until {}.".format(limit, reset)

    if wait:
        #Determine the delay and sleep
        delay = (reset - datetime.now()).total_seconds() + buffer
        print "Sleeping for {}s...".format(delay)
        sleep(delay)
        #We have waited for the rate limit reset. OK to proceed.
        return True
    else:
        #We have reached the rate limit. The user needs to handle the rate limit manually.
        return False 

    #We have not reached the rate limit
    return True

myStreamListener = MyStreamListener()
myStream = tweepy.Stream(auth = api.auth, listener=myStreamListener , 
tweet_mode='extended')


myStream.filter(track=['#bitcoin'],async=True)

有没有人有办法解决吗 ？

Answer 1

tweet_mode=extended在此代码中不起作用，因为Streaming API不支持该参数。如果Tweet包含更长的文本，它将在JSON响应中包含一个名为extended_tweet的附加对象，该对象将包含一个名为full_text的字段。

在这种情况下，你会想要像print(status.extended_tweet.full_text)这样的东西来提取更长的文本。

Answer 2

您必须启用扩展推文模式，如下所示：

s = tweepy.Stream(auth, l, tweet_mode='extended')

然后你可以打印扩展的推文，但记得由于Twitter API你必须确保存在扩展的推文，否则它会抛出错误

l = listener()

class listener(StreamListener):
    def on_status(self, status):
        try:
            print(status.extended_tweet['full_text'])
        except Exception as e:
            raise
        else:
            print(status.text)
        return True
    def on_error(self, status_code):
        if status_code == 420:
            return False

为我工作。

Answer 3

在@ AndyPiper的answer的基础上，您可以通过try / except检查推文是否在那里：

  def get_tweet_text(tweet):
    try:
      return tweet.extended_tweet['full_text']
    except AttributeError as e:
      return tweet.text

或检查内部json：

  def get_tweet_text(tweet):
    if 'extended_tweet' in tweet._json:
      return tweet.extended_tweet['full_text']
    else:
      return tweet.text

请注意，extended_tweet是一个字典对象，因此“tweet.extended_tweet.full_text”实际上不起作用并将引发错误。

Answer 4

除了之前的答案：在我的情况下它只作为status.extended_tweet['full_text']，因为status.extended_tweet只是一本字典。
