TypeError：_new_message（）缺少1个必需的位置参数：'message'

Question

嗨，我得到一个TypeError，我不知道我在做错了，类型错误是TypeError: _new_message() missing 1 required positional argument: 'message'我假设意味着我需要实例化一个类实例？

这就是我所做的，因为你可以看到我已经在代码中添加了message = ctx.message。

这是我正在使用的：

class antilink:
"""
Anti URL spam
"""

def __init__(self, bot):
    self.bot = bot
    self.regex = re.compile(r"<?(https?:\/\/)?(www\.)?(discord\.gg|discordapp\.com\/invite)\b([-a-zA-Z0-9/]*)>?")
    self.regex_discordme = re.compile(r"<?(https?:\/\/)?(www\.)?(discord\.me\/)\b([-a-zA-Z0-9/]*)>?")
    self.regex_url = re.compile(r'(?i)\b((?:[a-z][\w-]+:(?:/{1,3}|[a-z0-9%])|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:\'".,<>?«»“”‘’]))')


async def _new_message(self, ctx, message):
    """Finds the message and checks it for regex"""
    server = ctx.message.server
    user = message.author
    excluded = []
    message = ctx.message
    if ctx.message.server:
        if self.regex.search(ctx.message.content) is not None or self.regex_discordme.search(ctx.message.content) is not None \
            or self.regex_url.search(ctx.message.content)is not None and ctx.message.server:

                roles = [r.name for r in user.roles]
                bot_admin = settings.get_server_admin(ctx.message.server)
                bot_mod = settings.get_server_mod(ctx.message.server)
                if ctx.message.channel.id is excluded:
                    return
                elif user.id == settings.owner:
                    return
                elif bot_admin in roles:
                    return
                elif bot_mod in roles:
                    return
                elif user.permissions_in(ctx.message.channel).manage_messages is True:
                    return
                else:
                    asyncio.sleep(0.5)
                    await self.bot.delete_message(message)


def setup(bot):
    q = antilink(bot)
    bot.add_listener(q._new_message, 'on_message')
    bot.add_cog(q)

如果有人能帮到我，我会非常感激。

谢谢

如果您将q._new_message注册为on_message回调，则将使用on_message相同的参数调用它，这意味着单个Message参数表示已发送的消息。

async def _new_message(self, message):
    """Finds the message and checks it for regex"""
    server = message.server
    user = message.author
    excluded = []
    if server:
        if self.regex.search(message.content) is not None or self.regex_discordme.search(message.content) is not None \
            or self.regex_url.search(message.content)is not None and message.server:

                roles = [r.name for r in user.roles]
                bot_admin = settings.get_server_admin(message.server)
                bot_mod = settings.get_server_mod(message.server)
                if message.channel.id is excluded:
                    return
                elif user.id == settings.owner:
                    return
                elif bot_admin in roles:
                    return
                elif bot_mod in roles:
                    return
                elif user.permissions_in(message.channel).manage_messages is True:
                    return
                else:
                    asyncio.sleep(0.5)
                    await self.bot.delete_message(message)

你也可以定义一个async def on_message(self, message)方法，add_cog机器将自动注册为该名称事件的回调。
