我最近在使用discord.py和discord.ext命令扩展来创建机器人时遇到了一个问题
当我调用一个命令时,它会运行两次,导致许多bug和错误。它仅在添加此命令后才开始发生
@commands.command()
async def afk(self, ctx, userMessage):
#if user is already afk, remove them from the afk dict, if not add them to it
if ctx.message.author in self.afkUsers:
self.afkUsers.pop(ctx.message.author)
else:
self.afkUsers[ctx.message.author] = userMessage
但是,删除此命令并不能解决此问题。我在heroku上托管,但停止了,并在我自己的pc上运行它进行测试,但问题仍然存在。我在命令中使用print函数来测试它们是否运行了两次,其中的字符串是否输出了两次
我也有一个关于你的消息事件
@commands.Cog.listener()
async def on_message(self, message):
#if a member is mentioned but the member is afk, a message is sent
textChannel = message.channel
afkChannel = self.client.get_channel(690550327975346176)
for member in message.mentions:
if member in self.afkUsers:
await textChannel.send(f"user is afk- {self.afkUsers[member]}")
elif member in afkChannel.members:
await textChannel.send("user is afk")
#allows commands to work with on_message event
await self.client.process_commands(message)
编辑:在我的主文件中的一些命令上也会发生这种情况,但奇怪的是,只有一些命令受到影响
您正在为同一条消息呼叫
process_commands
两次。这是因为默认的on_message
侦听器已经调用了process_commands
。所以cog中的on_message
侦听器再次调用它。您应该从cogon_message
中删除process_commands
