在Python中解析Twitter JSON对象

Question

我想从twitter上下载推文.

我为此使用了python和Tweepy.虽然我是Python和Twitter API的新手.

我的Python脚本如下:#!usr/bin/python

#import modules
import sys
import tweepy
import json

#global variables
consumer_key = ''
consumer_secret = ''
token_key = ''
token_secret = ''

#Main function
def main():
    print sys.argv[0],'starts'
    auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
    auth.set_access_token(token_key, token_secret)
    print 'Connected to Twitter'
    api = tweepy.API(auth)
    if not api.test():
        print 'Twitter API test failed'

    print 'Experiment with cursor'
    print 'Get search method returns json objects'

   json_search = api.search(q="football")
   #json.loads(json_search())
   print  json_search


#Standard boilerplate to call main function if this file runs

if __name__ == '__main__':
    main()

我得到的结果如下:

[<tweepy.models.SearchResult object at 0x9a0934c>, <tweepy.models.SearchResult object at 0x9a0986c>, <tweepy.models.SearchResult object at 0x9a096ec>, <tweepy.models.SearchResult object at 0xb76d8ccc>, <tweepy.models.SearchResult object at 0x9a09ccc>, <tweepy.models.SearchResult object at 0x9a0974c>, <tweepy.models.SearchResult object at 0x9a0940c>, <tweepy.models.SearchResult object at 0x99fdfcc>, <tweepy.models.SearchResult object at 0x99fdfec>, <tweepy.models.SearchResult object at 0x9a08cec>, <tweepy.models.SearchResult object at 0x9a08f4c>, <tweepy.models.SearchResult object at 0x9a08eec>, <tweepy.models.SearchResult object at 0x9a08a4c>, <tweepy.models.SearchResult object at 0x9a08c0c>, <tweepy.models.SearchResult object at 0x9a08dcc>]

现在我很困惑如何从这些信息中提取推文？我试图对这些数据使用json.loads方法.但它给了我错误,因为JSON需要字符串或缓冲区.示例代码将受到高度赞赏.提前致谢.

Tweepy为您提供更丰富的物品; 它为你解析了JSON.

这些SearchResult对象具有与Twitter发送的JSON结构相同的属性; 只需查看Tweet文档即可查看可用内容:

for result in api.search(q="football"):
    print result.text

演示:

>>> import tweepy
>>> tweepy.__version__
'3.3.0'
>>> consumer_key = '<consumer_key>'
>>> consumer_secret = '<consumer_secret>'
>>> access_token = '<access_token>'
>>> access_token_secret = '<access_token_secret>'
>>> auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
>>> auth.set_access_token(access_token, access_token_secret)
>>> api = tweepy.API(auth)
>>> for result in api.search(q="football"):
...     print result.text
