基于pytesseract的discord机器人

Question

我正在尝试创建一个基于 pytesseract 的discord机器人，该机器人基本上可以扫描以图片形式发布的任何邮件，然后将其读取，与禁令匹配并将其删除。不知道我在做什么，但无法正常工作。希望对下面的代码发表评论。

import discord
from PIL import Image
from pytesseract import image_to_string
import requests
from io import BytesIO
import re

# Variables
bot = discord.Client()

# Discord
@bot.event
async def on_ready():
    print("Filter Bot Started: " + bot.user.name)

@bot.event
async def on_message(message):
    txt_urls = re.findall('(?:(?:https?|ftp):\/\/)?[\w/\-?=%.]+\.[\w/\-?=%.]+', message.content)
    for url in txt_urls:
        if check_url(url) == False:
            await bot.delete_message(message)
            print("Link deleted!")
            break


# Extracting Text
def check_url(url):
    try:
        response = requests.get(url)
        while True:
            r = requests.head(url)
            if 300 < r.status_code < 400:
                url = r.headers['location']
                text = url.lower()
                if "discord" in text:
                    return False
                    break
            else:
                break
        print("Url not an redirect")
        img = Image.open(BytesIO(response.content))
        img_text = image_to_string(img)
        img_text = img_text.lower()
        if "Badword" in img_text or "FWORD" in img_text:
            print("Prohibited word found!")
            return False
        else:
            print("Link passed the test")
            return True
    except:
        return True

# Run Bot
bot.run('BOT TOKEN XXXXX')```
