如何在 Z23EEEB4347BDD26BDDZ6B7EE9A3B75 中的 api twitter 响应中获取 json 响应中的特定数据密钥

Question

I am trying to get attributes of only "id" and "text" in the result of response API Twitter. But the below code result all key attribute. How to get the data "id" and "text"?

from tweepy import Stream
from tweepy.streaming import StreamListener

class StdOutListener(StreamListener):

def on_data(self, data):
    try:
        with open('python2.json', 'a') as f:
            f.write(data)
            return True
    except BaseException as e:
        print("Error on_data: %s" % str(e))
    return True

def on_error(self, status_code):
    if status_code == 420:
        print(status_code)
        return False

if __name__ == '__main__':
    l = StdOutListener()
    auth = OAuthHandler(consumer_key, consumer_secret)
    auth.set_access_token(access_token, access_token_secret)
    stream = Stream(auth, l)
    hasil = stream.filter(track=['wedding','sunday'])

the result:

 {"created_at":"Sun Apr 04 17:16:28,
 "id":1378758380722946049,
 "id_str":"1378758380722946049",
 "text":"Nonton wedding atta aurel jadi pen nikah",
 "source":"Twitter Web",
 "truncated":false,
 "in_reply_to_status_id":null,
 "in_reply_to_status_id_str":null
 }

the expected result just id and text

{
 "id":1378758380722946049,
 "text":"Nonton wedding atta aurel jadi pen nikah"
}

It looks like you want to only write a JSON containing the id and text fields, so this modified version of your code will correctly take both those fields out of jsonData , create it's own new JSON only containing id and text ( newJSON ) and then write it to your file.

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

class StdOutListener(StreamListener):

    def on_data(self, data):
        try:
            with open('python2.json', 'a') as f:
                jsonData = json.loads(data)
                id = jsonData["id"]
                text = jsonData["text"]
                newJSON = {'id': id, 'text': text}
                f.write(json.dumps(data))
                return True
        except BaseException as e:
            print("Error on_data: %s" % str(e))
        return True

PS: Your code in your question has severe formatting problems, on_data and on_error should be indented under the StdOutListener class.
