使用configparser传递API凭证时出现问题

托马斯·德格雷夫

我有一个看起来像这样的config.ini文件

[REDDIT]
client_id = 'myclientid23jd934g'
client_secret = 'myclientsecretjf30gj5g'
password = 'mypassword'
user_agent = 'myuseragent'
username = 'myusername'

当我尝试使用reddit的API代理时，如下所示：

import configparser
import praw

class redditImageScraper:
    def __init__(self, sub, limit):
        config = configparser.ConfigParser()
        config.read('config.ini')
        self.sub = sub
        self.limit = limit
        self.reddit = praw.Reddit(client_id=config.get('REDDIT','client_id'),
                                  client_secret=config.get('REDDIT','client_secret'),
                                  password=config.get('REDDIT','password'),
                                  user_agent=config.get('REDDIT','user_agent'),
                                  username=config.get('REDDIT','username'))


    def get_content(self):
        submissions = self.reddit.subreddit(self.sub).hot(limit=self.limit)
        for submission in submissions:
            print(submission.id)

def main():
    scraper = redditImageScraper('aww', 25)
    scraper.get_content()

if __name__ == '__main__':
    main()

我得到这个回溯

Traceback (most recent call last):
  File "config.py", line 30, in <module>
    main()
  File "config.py", line 27, in main
    scraper.get_content()

    for submission in submissions:

    kwargs['headers'] = set_header_callback()

    self._authorizer.refresh()

    password=self._password)
  File "C:\Users\Evan\Anaconda3\lib\site-packages\prawcore\auth.py", line 138, in _request_token
    response = self._authenticator._post(url, **data)
  File "C:\Users\Evan\Anaconda3\lib\site-packages\prawcore\auth.py", line 31, in _post
    raise ResponseException(response)
prawcore.exceptions.ResponseException: received 401 HTTP response

但是，当我手动插入凭据时，我的代码将按预期运行。另外，如果我跑线

print(config.get('REDDIT', 'client_id'))

我得到'myclientid23jd934g'预期的输出。

出于某种原因，praw不允许我使用configparser传递凭据？

仔细检查您要输入praw.Reddit的内容：

kwargs = dict(client_id=config.get('REDDIT','client_id'),
              client_secret=config.get('REDDIT','client_secret'),
              password=config.get('REDDIT','password'),
              user_agent=config.get('REDDIT','user_agent'),
              username=config.get('REDDIT','username'))) 
print(kwargs)
praw.Reddit(**kwargs)
