问题描述
我希望我的机器人在使用已定义的函数 (+play) 键入 +playtest 时播放特定歌曲但我有一个错误说
I want my bot to play a specific song when typing +playtest using already defined function (+play) but i got an error says
Discord.ext.commands.errors.CommandInvokeError:命令引发了异常:TypeError:命令"对象不可调用"
"Discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: 'Command' object is not callable"
除此命令外,整个代码都可以正常工作我想知道 ctx.invoke 是否启用传递参数?或者我只是错过了一些东西
an entire code work perfectly fine except for this command i wonder does ctx.invoke enable passing arguments? or i just missed something
这是我的简短代码
import discord import wavelink from discord.ext import commands import asyncio from bs4 import BeautifulSoup import requests import datetime queue = [] class Bot(commands.Bot): def __init__(self): super(Bot, self).__init__(command_prefix=['+']) self.add_cog(Music(self)) async def on_ready(self): print(f'Logged in as {self.user.name} | {self.user.id}') class Music(commands.Cog): def __init__(self, bot): self.bot = bot if not hasattr(bot, 'wavelink'): self.bot.wavelink = wavelink.Client(bot=self.bot) self.bot.loop.create_task(self.start_nodes()) self.bot.remove_command("help") async def start_nodes(self): await self.bot.wait_until_ready() await self.bot.wavelink.initiate_node(host='127.0.0.1', port=80, rest_uri='http://127.0.0.1:80', password='testing', identifier='TEST', region='us_central') @commands.command(name='connect') async def connect_(self, ctx, *, channel: discord.VoiceChannel = None): @commands.command() async def help(self, ctx): @commands.command() async def play(self, ctx, *, query: str): @commands.command(aliases=['sc']) async def soundcloud(self, ctx, *, query: str): @commands.command() async def leave(self, ctx): @commands.command(aliases=['queue', 'q']) async def check_queue(self, ctx): @commands.command(aliases=['clearq', 'clearqueue']) async def clear_queue(self, ctx): @commands.command(aliases=['removequeue', 'removeq', 'req']) async def remove_queue(self, ctx, num: int): @commands.command() async def skip(self, ctx): @commands.command(aliases=['eq']) async def equalizer(self, ctx: commands.Context, *, equalizer: str): @commands.command() async def playtest(self,ctx): await ctx.invoke(self.play('hi')) bot = Bot() bot.run('sd')
推荐答案
ctx.invoke 确实允许传递参数,但它们需要以不同于您习惯的方式处理(function(params) )
ctx.invoke does allow passing arguments, but they need to be handled in a different way to how you may be used to ( function(params) )
参数必须在调用中显式显示(例如 param = 'value')并且命令必须是命令对象.这就是你可以调用命令的方式:
The parameters must be explicitly shown in the invoke (e.g. param = 'value') and the command must be a command object. This would be how you could invoke a command:
@commands.command() async def playtest(self, ctx): await ctx.invoke(self.bot.get_command('play'), query='hi')
