使用Tweepy获取Twitter数据

Question

我正在使用Python代码和Tweepy库来获取特定标签（hashtag）的Twitter数据，但我想知道如何获取特定时间段的数据，比如从2013年6月30日到2013年12月30日。我该怎么做呢？

#imports
from tweepy import Stream
from tweepy import OAuthHandler
from tweepy.streaming import StreamListener

#setting up the keys
consumer_key = '……………….'
consumer_secret = '……………..' 
access_token = '……………….'
access_secret = '……………..'

class TweetListener(StreamListener):
# A listener handles tweets are the received from the stream.
#This is a basic listener that just prints received tweets to standard output

  def on_data(self, data):
    print (data)
    return True

  def on_error(self, status):
    print (status)



#printing all the tweets to the standard output
auth = OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_secret)



stream = Stream(auth, TweetListener())

t = u"#سوريا"
stream.filter(track=[t])

Answer 1

我还在调查为什么我用 tweepy.Cursor(api.search, geocode=.., q=query, until=date ) 不能得到相同的结果。也许是因为这个 原因。不过，我可以通过以下步骤在两个日期之间获取Twitter数据。

首先，我创建了一个日期生成器，用来生成开始日期和结束日期之间的所有日期。

def date_range(start,end):
   current = start
   while (end - current).days >= 0:
      yield current
      current = current + datetime.timedelta(seconds=1)  #Based on your need, but you could do it per day/minute/hour

然后，我创建了一个 Listener，这样我就可以通过访问 status.created_at 来获取特定日期创建的推文。

你的代码应该像这样：

import tweepy 
from tweepy import Stream
from tweepy import OAuthHandler
from tweepy.streaming import StreamListener
import json
import datetime 


#Use your keys
consumer_key = '...'
consumer_secret = '...' 
access_token = '...'
access_secret = '...'


auth = OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_secret)

def date_range(start,end):
   current = start
   while (end - current).days >= 0:
      yield current
      current = current + datetime.timedelta(seconds=1)  

class TweetListener(StreamListener):
    def on_status(self, status):
        #api = tweepy.API(auth_handler=auth)
        #status.created_at += timedelta(hours=900)

        startDate = datetime.datetime(2013, 06, 30)
        stopDate = datetime.datetime(2013, 10, 30)
        for date in date_range(startDate,stopDate):
            status.created_at = date
            print "tweet " + str(status.created_at) +"\n"
            print status.text + "\n"  
            # You can dump your tweets into Json File, or load it to your database

stream = Stream(auth, TweetListener(), secure=True, )
t = u"#Syria" # You can use different hashtags 
stream.filter(track=[t])

输出：

我只是打印了这些日期来检查一下（我不想在StackOverflow上刷政治推文）。
