为什么 on_message 会停止命令工作? [英] Why does on_message stop commands from working?

问题描述

基本上，一切似乎都能正常工作并启动，但由于某种原因我无法调用任何命令.我已经轻松地环顾了一个小时，查看示例/观看视频，但我终生无法弄清楚出了什么问题.代码如下:

Basically, everything appears to work fine and start up, but for some reason I can't call any of the commands. I've been looking around for easily an hour now and looking at examples/watching videos and I can't for the life of me figure out what is wrong. Code below:

import discord
import asyncio
from discord.ext import commands

bot = commands.Bot(command_prefix = '-')
@bot.event
async def on_ready():
    print('Logged in as')
    print(bot.user.name)
    print(bot.user.id)
    print('------')

@bot.event
async def on_message(message):
    if message.content.startswith('-debug'):
        await message.channel.send('d')

@bot.command(pass_context=True)
async def ping(ctx):
    await ctx.channel.send('Pong!')

@bot.command(pass_context=True)
async def add(ctx, *, arg):
    await ctx.send(arg)

我在 on_message 中的调试输出实际上确实有效并做出了响应，并且整个机器人在没有任何异常的情况下运行，但它只是不会调用命令.

The debug output I have in on_message actually does work and responds, and the whole bot runs wihout any exceptions, but it just won't call the commands.

推荐答案

来自文档:

覆盖默认提供的 on_message 禁止运行任何额外的命令.要解决此问题，请在 on_message 的末尾添加 bot.process_commands(message) 行.例如:

Overriding the default provided on_message forbids any extra commands from running. To fix this, add a bot.process_commands(message) line at the end of your on_message. For example:

@bot.event
async def on_message(message):
    # do some extra stuff here

    await bot.process_commands(message)

默认的on_message包含对这个协程的调用，但是当你用你自己的on_message覆盖它时，你需要自己调用它.

The default on_message contains a call to this coroutine, but when you override it with your own on_message, you need to call it yourself.
