discord.py 中的 client.wait_for 中的“检查未定义”

Question

我想在给我的 discord bot 发出命令=hi 后阅读作者发送的消息。所以我用我在网上找到的这段代码来获取作者发送的内容：

msg = await client.wait_for('message', check=check) #error goes here, 'check' is not defined
await ctx.send(msg.content)

但问题是check在这个函数运行时没有定义

Traceback (most recent call last):
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/bot.py", line 939, in invoke
    await ctx.command.invoke(ctx)
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/core.py", line 863, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/core.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: NameError: name 'check' is not defined

我该如何解决？ 这个函数前面我没有定义check，但是check怎么定义呢？

检查是这样的：

def check(m):
    return m.author == ctx.author and m.channel == ctx.channel

只需将其添加到您的命令函数中及上方

msg = await client.wait_for('message', check=check)

所以：

def check(m):
    return m.author == ctx.author and m.channel == ctx.channel

msg = await client.wait_for('message', check=check)
await ctx.send(msg.content)
