尝试使用 Discord.py rewrite 向特定频道发送消息,但它不起作用
问题描述
我目前正在开发一个 discord 机器人,我正在尝试在用户升级后使用 Discord.py rewrite 向特定频道发送消息,但我收到此错误:
I'm currently working on a discord bot and I'm trying to send a message to a specific channel using Discord.py rewrite once the user levels up, and I'm getting this error:
await channel.message.send(f"{message.author.mention} is now level {self.users[author_id]['level']}! congrats!")
AttributeError: 'NoneType' object has no attribute 'message'
所有代码如下:
import discord
from discord.ext import commands
import json
import asyncio
class Levels(commands.Cog):
@commands.Cog.listener()
async def on_message(self, message):
if message.author == self.bot.user:
return
author_id = str(message.author.id)
bot = commands.Bot(command_prefix='!')
if author_id not in self.users:
self.users[author_id] = {}
self.users[author_id]['level'] = 1
self.users[author_id]['exp'] = 0
self.users[author_id]['exp'] += 1
if author_id in self.users:
if self.lvl_up(author_id):
channel = bot.get_channel('636399538650742795')
await channel.message.send(f"{message.author.mention} is now level {self.users[author_id]['level']}! congrats!")
def __init__(self, bot):
self.bot = bot
with open(r"cogsuserdata.json", 'r') as f:
self.users = json.load(f)
self.bot.loop.create_task(self.save_users())
async def save_users(self):
await self.bot.wait_until_ready()
while not self.bot.is_closed():
with open(r"cogsuserdata.json", 'w') as f:
json.dump(self.users, f, indent=4)
await asyncio.sleep(5)
def lvl_up(self, author_id):
author_id = str(author_id)
current_xp = self.users[author_id]['exp']
current_lvl = self.users[author_id]['level']
if current_xp >= ((3 * (current_lvl ** 2)) / .5):
self.users[author_id]['level'] += 1
return True
else:
return False
我真的不确定这里的问题是什么,但如果有人知道这个问题,如果你能告诉我如何解决这个问题,我将非常感激.
I'm really not sure what the issue is here but if anyone knows the problem I would be very appreciative if you could let me know how I can correct this.
感谢阅读我已经尝试了好几个小时.
Thanks for reading I've been trying to figure this out for hours.
仍然有问题.
解决方案
你得到 AttributeError
因为 channel
是 None.
You get AttributeError
because channel
is None.
要修复它,您需要从频道 ID 中删除引号,如下所示:
To fix it you need to remove quotes from channel id like this:
channel = bot.get_channel(636399538650742795)
此处对此进行了描述:https://discordpy.readthedocs.io/en/latest/migrating.html#snowflakes-are-int
我还在下一行看到另一个错误.channel
也没有 message
属性.我认为您需要像这样修复它:
Also i see another error on the next line. The channel
has no message
attribute too. I think you need to fix it like this:
await channel.send(f"{message.author.mention} is now level {self.users[author_id]['level']}! congrats!")
