python-3.x - Python 中的 Reddit 和 Twitter bot 使用 PRAW

Question

我是 Python 的初学者，正在尝试制作一个机器人，它会自动推文发布在我制作的 Subreddit 上的任何内容。

我从一些在线教程中获得了帮助，其中包含以下代码

import praw
import json
import requests
import tweepy
import time

access_token = '************************************'
access_token_secret = '************************************'
consumer_key = '************************************'
consumer_secret = '************************************'

def strip_title(title):
    if len(title) == 94:
        return title
    else:
        return title[:93] + "..."

def tweet_creator(subreddit_info):
    post_dict = {}
    post_ids = []
    print("[bot] Getting posts from Reddit")
    for submission in subreddit_info.get_hot(limit=20):
        post_dict[strip_title(submission.title)] = submission.url
        post_ids.append(submission.id)
    print("[bot] Generating short link using goo.gl")
    mini_post_dict = {}
    for post in post_dict:
        post_title = post
        post_link = post_dict[post]
        short_link = shorten(post_link)
        mini_post_dict[post_title] = short_link
    return mini_post_dict, post_ids

def setup_connection_reddit(subreddit):
    print("[bot] setting up connection with Reddit")
    r = praw.Reddit(' %s' %(subreddit))
    subreddit = r.get_subreddit(subreddit)
    return subreddit

def shorten(url):
    headers = {'content-type': 'application/json'}
    payload = {"longUrl": url}
    url = "https://www.googleapis.com/urlshortener/v1/url"
    r = requests.post(url, data=json.dumps(payload), headers=headers)
    link = json.loads(r.text)['id']
    return link

def duplicate_check(id):
    found = 0
    with open('posted_posts.txt', 'r') as file:
        for line in file:
            if id in line:
                found = 1
    return found


def add_id_to_file(id):
    with open('posted_posts.txt', 'a') as file:
        file.write(str(id) + "\n")

def main():
    subreddit = setup_connection_reddit('*Name of the subreddit*')
    post_dict, post_ids = tweet_creator(subreddit)
    tweeter(post_dict, post_ids)

def tweeter(post_dict, post_ids):
    auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
    auth.set_access_token(access_token, access_token_secret)
    api = tweepy.API(auth)
    for post, post_id in zip(post_dict, post_ids):
        found = duplicate_check(post_id)
        if found == 0:
            print("[bot] Posting this link on twitter")
            print(post + " " + post_dict[post] + " #Python #reddit #bot")
            api.update_status(post+" "+post_dict[post]+" #Python #reddit #bot")
            add_id_to_file(post_id)
            time.sleep(30)
        else:
            print("[bot] Already posted")

if __name__ == '__main__':
    main()

代码在 PyCharm 中似乎很好，但是当我尝试使用滚动代码通过终端直接从文件夹运行它时出现以下错误，reddit_bot2.py 是我的文件名：

 python3 reddit_bot2.py

当我尝试运行代码时，出现以下错误：

mahesh@Maheshs-MacBook-Air Atoms % python3 reddit_bot2.py
[bot] setting up connection with Reddit
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/configparser.py", line 846, in items
d.update(self._sections[section])
KeyError: '**Name of the subreddit to fetch posts from**'

During handling of the above exception, another exception occurred:

You provided the name of a praw.ini configuration which does not exist.
