在 discord.py 中发出禁令命令的正确方法是什么？

Question

我正在制作一个名为 Excelsior 的不和谐机器人。它的命令之一是禁止命令，顾名思义，就是禁止用户访问服务器。

这是针对我的错误的代码：

elif message.content.startswith("e? ban"):
    li = list(message.content)
    if len(li) == 2:
      await message.channel.send("Who do I ban?")
    else:
      await ban(message, li[2])

它的工作方式是将命令拆分为一个列表。然后它获取列表中的第二项，它必须是用户的用户名，并将其插入到我的完整代码中的禁令命令中（见下文）。

然而，每当我运行e? ban [user] 命令时，程序都会给我一个错误，即用户名的字符串没有ban 属性。我相信这是因为我将文字字符串传递给函数。

我的问题是如何将用户名（或 id）输入到机器人中，以便禁令功能实际上可以找到用户名？我如何让它发挥作用？

这是机器人的代码：¹

  await member.ban(reason = reasons)

    embed.add_field(name = "Commands:", value = "`e? help` \n `e? roll` \n `e? copy` \n `e? work`")
    await message.channel.send(embed = embed)
  
  elif message.content.startswith("e? roll"):
    embed = discord.Embed(title = "Roll a die :game_die:", description = "This command rolls a die and gives you a random number between 1 and 6.", color = 0xff000)
    embed.add_field(name = "Your number:", value = random.randint(1, 6))
    await message.channel.send(embed = embed)

      embed.add_field(name = "`e? copy (what you want me to say)`", value = "I need something to copy!")
      await message.channel.send(embed = embed)
    else: 
      string = ""
      for item in list_of_words[2:len(list_of_words)]:
        string += item
        string += " "
      message_sent = "\""+string+"\""
      await message.channel.send(message_sent)
  
  elif message.content.startswith("e? work"):
    num1 = random.randint(1, 10)
    op = ["*", "/", "+", "-"]

    embed = discord.Embed(title = "What is the correct answer to the problem below?", description = mess, color = 0x0000ff)

我已经看过以下问题：

• Discord.py ban command。这不能回答我的问题，因为虽然它提供了实际的 ban 函数，但它没有解决我想在运行 ban 命令后运行该命令。同样在那个问题中，用户ID是直接输入到函数中的，但我没有那种奢侈。

如果需要更多信息，我很乐意提供。

在 cmets 中进行对话后，我编写了一个 MCVE，它应该根据 cmets 工作，但它没有。

这是 MCVE 的代码（要短得多）：

import discord
import os
import random
from keep_alive import keep_alive
from discord_components import DiscordComponents, Button, ButtonStyle, InteractionEventType
from discord.ext.commands import Bot
from discord.ext import commands
 
client2 = commands.Bot(command_prefix = "e? ")
client = discord.Client()
bot = Bot("e? ")
 
@client.event
async def on_ready():
  print("Ready! {0.user}".format(client))
 
@client2.command(name = "ban")
@commands.has_permissions(administrator = True)
async def ban(ctx, member: discord.Member, reasons = "No reason"):
  await member.ban(reason = reasons)
 
keep_alive()
client.run(os.getenv("TOKEN"))

然而，上面的代码甚至不承认e? ban 命令。在 cmets 中有人告诉我，我可以按照我现在的方式来做。

应该如何处理？

Answer 1

首先： on_message 事件仅作为参数 message

第二：您的代码一团糟，您同时使用client 和bot 作为您的命令，client2 应该是什么意思？我可以看到您可能对 dpy 或 python 一般没有太多经验，但是，在提出问题之前，我建议您至少做最少的努力并阅读该库的文档，那里有明确的示例。

如果您决定使用client，请选择：

client = commands.Bot(command_prefix=" ") # your prefix between " "

第三：禁止命令

@client.command()
@commands.has_permissions(administrator=True) # though imo i would put just ban_members perm for this.
async def ban(ctx, member: discord.Member = None, *, reason=None)
    if member == ctx.author:
       await ctx.send("You can't ban yourself")
       return
    await member.ban(reason=reason)
    await ctx.send("User banned")

你有它，一个非常基本的命令，如果你已经有这段代码client = commands.Bot(command_prefix=" ")，请停止在on_message事件上使用前缀
