如何删除不和谐机器人的最新消息？- Discord.py

Question

我试图制作一个清除命令，这是我的代码：

@bot.command(pass_context=True)
@commands.has_permissions(administrator=True)
async def purge(ctx, limit: int):
await ctx.channel.purge(limit=limit)
await ctx.message.delete()
await ctx.send(f'Deleted {limit} messages. Done by {ctx.author.mention}.')
await asyncio.sleep(2)
await bot.delete.message.most_recent()

但当我尝试运行该命令时，它会删除消息，但当它尝试删除消息时会出现以下错误：

Ignoring exception in command purge:
Traceback (most recent call last):
File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/core.py", line 85, in wrapped
ret = await coro(*args, **kwargs)
File "main.py", line 312, in purge
await ctx.message.delete()
File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/message.py", line 1023, in delete
await self._state.http.delete_message(self.channel.id, self.id)
File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/http.py", line 250, in request
raise NotFound(r, data)
discord.errors.NotFound: 404 Not Found (error code: 10008): Unknown Message
The above exception was the direct cause of the following exception:
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: NotFound: 404 Not Found (error code: 10008): Unknown Message

有什么帮助吗？

Answer 1

您可以尝试以下操作：

@bot.command(pass_context=True)
@commands.has_permissions(administrator=True)
async def purge(ctx, limit: int):
await ctx.channel.purge(limit=limit)
await ctx.message.delete()
await ctx.send(f'Deleted {limit} messages. Done by {ctx.author.mention}.', delete_after = 2)

delete_after在特定秒数后删除bot发送的消息。

答案很晚，但我认为这可能会对您有所帮助。使用您的代码，您所要做的就是将刚刚发送的消息保存到一个变量中，然后删除该消息。

@bot.command()
@commands.has_permissions(administrator=True)
async def purge(ctx, limit: int):
await ctx.channel.purge(limit=limit)
await ctx.message.delete()
message = await ctx.send(f'Deleted {limit} messages. Done by {ctx.author.mention}.')
await asyncio.sleep(2)
await message.delete()
