background_task.py 不显示消息 - Python
background_task.py not showing messages - Python
我注意到当我 运行 来自 discord.py Github 页面的代码片段时,它没有显示预期的消息。
我稍微修改的代码:
import discord
import asyncio
import nest_asyncio
nest_asyncio.apply()
class MyClient(discord.Client):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
# create the background task and run it in the background
self.bg_task = self.loop.create_task(self.my_background_task())
async def on_ready(self):
print('Logged in as')
print(self.user.name)
print(self.user.id)
print('------')
async def my_background_task(self):
counter = 0
channel = self.get_channel(1234567890) # channel ID goes here
while not self.is_closed():
counter += 1
await channel.send(counter)
await asyncio.sleep(10) # task runs every 10 seconds
client = MyClient()
client.run('token')
当我检查 Discord 时没有任何显示,但它确实在 IDLE 中显示输出:
Logged in as
bot_name
1234567890
------
但在 Discord 服务器中,没有任何反应。有办法解决这个问题吗?
代码失败,因为在 bot 正确连接之前使用 self.get_channel(1234567890)
,导致它总是返回 None
。这是因为 client = MyClient()
先完成,这意味着后台任务已创建但 bot 尚未连接,这是通过 client.run
.
完成的
要解决此问题,请将循环的创建移动到 on_ready
事件内部。
