回复评论的 Reddit Bot

Question

使用 PRAW 库，当提到给定关键字时，reddit 机器人会在子线程中回复帖子标题。我想更改，以便在子中的 cmets 中提及时回复，而不是帖子。

from urllib.parse import quote_plus

    import praw

    QUESTIONS = ["!hello"]
    REPLY_TEMPLATE = "world"


    def main():
        reddit = praw.Reddit(
            user_agent="xxx",
            client_id="xxx",
            client_secret="xxx",
            username="xxx",
            password="xxx",
        )

        subreddit = reddit.subreddit("sandboxtest")
        for submission in subreddit.stream.submissions():
            process_submission(submission)


    def process_submission(submission):
        # Ignore titles with more than 10 words as they probably are not simple
        # questions.
        if len(submission.title.split()) > 15:
            return

        normalized_title = submission.title.lower()
        for question_phrase in QUESTIONS:
            if question_phrase in normalized_title:
                url_title = quote_plus(submission.title)
                reply_text = REPLY_TEMPLATE.format(url_title)
                print("Replying to: {}".format(submission.title))
                submission.reply(reply_text)
                # A reply has been made so do not attempt to match other phrases.
                break


    if __name__ == "__main__":
        main()

如果你只想处理 cmets 变化：

for submission in subreddit.stream.submissions():
  process_submission(submission)

到：

for comment in subreddit.stream.comments():
  process_comment(comment)

# def process_comment you have to write yourself

---

如果您想处理 cmets 和提交，请执行以下操作：

while True:
  for submission in subreddit.stream.submissions(pause_after=-1):
    process_submission(submission)
  for commentin subreddit.stream.comments(pause_after=-1):
    process_comment(comment)

---

process_comment() 的示例：

def process_comment(comment):
  for question_phrase in QUESTIONS:
    if question_phrase in comment.body.lower():
      comment.reply("Hello")
