使用Python从Twitter流API中提取特定的JSON字段

pip install tweepy

import tweepy
import json

# 填入你的Twitter API密钥和访问令牌
consumer_key = "YOUR_CONSUMER_KEY"
consumer_secret = "YOUR_CONSUMER_SECRET"
access_token = "YOUR_ACCESS_TOKEN"
access_token_secret = "YOUR_ACCESS_TOKEN_SECRET"

# 创建认证对象
auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)

# 创建API对象
api = tweepy.API(auth)

# 创建自定义StreamListener类
class MyStreamListener(tweepy.StreamListener):
    def on_status(self, status):
        # 提取特定的JSON字段
        tweet_text = status.text
        user_name = status.user.screen_name
        created_at = status.created_at

        # 打印提取的字段
        print("Tweet Text:", tweet_text)
        print("User Name:", user_name)
        print("Created At:", created_at)
        print()

    def on_error(self, status_code):
        if status_code == 420:
            # 返回False表示停止流
            return False

# 创建Stream对象
myStreamListener = MyStreamListener()
myStream = tweepy.Stream(auth = api.auth, listener=myStreamListener)

# 过滤器，指定要提取的关键词
keywords = ['python', 'twitter']
myStream.filter(track=keywords)
