Trouble using configparser to pass API credentials

Question

I have a config.ini file that looks like this

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

When I try to use reddit's API praw like this:

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()

I get this traceback

Traceback (most recent call last):

  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

However when I manually insert the credentials, my code runs exactly as expected. Also, if I run the line

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

I get the output 'myclientid23jd934g' as expected.

Is there some reason that praw won't allow me to pass my credentials using configparser?

Answer 1

Double check what your inputs to praw.Reddit are:

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)
