on_message() 和@bot.command 问题

问题描述

当我的代码中有 on_message() 时，它会停止所有其他 @bot.command 命令的工作.我尝试过 await bot.process_commands(message)，但这也不起作用.这是我的代码:

When I have on_message() in my code, it stops every other @bot.command commands from working. I've tried to await bot.process_commands(message), but that doesn't work either. Here is my code that I have:

@bot.event
@commands.has_role("Owner")
async def on_message(message):
    if message.content.startswith('/lockdown'):
        await bot.process_commands(message)
        embed = discord.Embed(title=":warning: Do you want to activate Lock Down?", description="Type 'confirm' to activate Lock Down mode", color=0xFFFF00)
        embed.add_field(name="u200b", value="Lock Down mode is still in early development, expect some issues")
        channel = message.channel
        await bot.send_message(message.channel, embed=embed)
        msg = await bot.wait_for_message(author=message.author, content='confirm')
        embed = discord.Embed(title=":white_check_mark: Lock Down mode successfully activated", description="To deactivate type '/lockdownstop'", color=0x00ff00)
        embed.add_field(name="u200b", value="Lock Down mode is still in early development, expect some issues")
        await bot.send_message(message.channel, embed=embed)

解决方案

你必须将 await bot.process_commands(message) 放在 if 语句范围之外，<无论消息是否以/lockdown"开头，都应运行code>process_command.

You have to place await bot.process_commands(message) outside of the if statement scope, process_command should be run regardless if the message startswith "/lockdown".

@bot.event
async def on_message(message):
    if message.content.startswith('/lockdown'):
       ...
    await bot.process_commands(message)

顺便说一句，@commands.has_role(...) 不能应用于 on_message.尽管没有任何错误(因为检查到位)，但 has_role 实际上不会像您预期的那样工作.

By the way, @commands.has_role(...) cannot be applied to on_message. Although there aren't any errors (because there’s checking in place), has_role wouldn't actually work as you would've expected.

@has_role 装饰器的替代方案是:

An alternative to the @has_role decorator would be:

@bot.event
async def on_message(message):
    if message.channel.is_private or discord.utils.get(message.author.roles, name="Admin") is None:
        return False

    if message.content.startswith('/lockdown'):
       ...
    await bot.process_commands(message)
