我正在尝试创建一个从 reddit 发布随机模因的命令，但我不断收到 401 HTTP 响应错误，这是我的代码：
@commands.command()
async def meme(self, ctx):
reddit = praw.Reddit(client_id='id here',
client_secret='secret here',
user_agent='Mozilla/5.0 (iPhone; CPU iPhone OS 10_3_2 like Mac OS X) AppleWebKit/603.2.4 (KHTML, like Gecko) FxiOS/7.5b3349 Mobile/14F89 Safari/603.2.4')
memes_submissions = reddit.subreddit('memes').hot()
post = random.randint(1, 10)
for i in range(0, post):
submission = next(x for x in memes_submissions if not x.stickied)
await self.client.say(submission.url)
