Question

我无法检索环境变量。

我尝试了Tweepy文档中的示例代码段，没有环境变量，并且该代码段应能正常工作。我直接在代码中定义了所需的变量。

然后我为consumer_key, consumer_secret, access_token and access_token_secret定义了 4个环境变量，但此方法不再起作用。让我感到奇怪的是，我可以使用print(os.environ['TWITTER_CONSUMER_KEY'])访问环境变量，并且输出正确。

键中没有任何错字。我仔细检查了。

此代码有效：

import tweepy

consumer_key = 'xyz'
consumer_secret = 'xyz'
access_token = 'xyz'
access_token_secret = 'xyz'

auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)

api = tweepy.API(auth)

public_tweets = api.home_timeline()
for tweet in public_tweets:
    print(tweet.text)

此代码无效：

import os
import tweepy

consumer_key = os.environ['TWITTER_CONSUMER_KEY']
consumer_secret = os.environ['TWITTER_CONSUMER_SECRET']
access_token = os.environ['TWITTER_ACCESS_TOKEN']
access_token_secret = os.environ['TWITTER_ACCESS_SECRET']

auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)

api = tweepy.API(auth)

public_tweets = api.home_timeline()
for tweet in public_tweets:
    print(tweet.text)

我收到以下错误消息：

Traceback (most recent call last):   
File "[...]/testing.py", line 28, in <module>
   public_tweets = api.home_timeline()
File "[...]venv\lib\site-packages\tweepy\binder.py", line 250, in _call 
   return method.execute()
File "[...]\venv\lib\site-packages\tweepy\binder.py", line 234, in execute 
   raise TweepError(error_msg, resp, api_code=api_error_code) tweepy.error.TweepError: [{'code': 32, 'message': 'Could not authenticate you.'}]

您需要上传dotenv库

from dotenv import load_dotenv
load_dotenv()

环境变量在PyCharm中不起作用，无法在Tweepy中使用
