Discord.py Bot的权限系统

  Permissions是该类的名称 . 要获取消息作者权限，您应该访问作者的server_permissions属性 .

  if ctx.message.author.server_permissions.administrator:
   # you could also use server_permissions.kick_members
  

  更新：

  验证调用命令的人员权限的更好方法是使用 commands 扩展名的check功能，特别是has_permissions检查 . 例如，如果您只想向拥有 manage_roles 权限或 ban_members 权限的人员打开命令，您可以像这样编写命令：

  from discord import Member
  from discord.ext.commands import has_permissions, MissingPermissions
  
  @bot.command(name="kick", pass_context=True)
  @has_permissions(manage_roles=True, ban_members=True)
  async def _kick(ctx, member: Member):
      await bot.kick(member)
  
  @_kick.error
  async def kick_error(error, ctx):
      if isinstance(error, MissingPermissions):
          text = "Sorry {}, you do not have permissions to do that!".format(ctx.message.author)
          await bot.send_message(ctx.message.channel, text)

  发现接受的答案的提示可能不起作用：

  • discord.py库的重写版本和预重写版本可能存在兼容性问题，这些版本仍然是非过时的，不推荐使用且仍在使用中 .

  • 机器人还应该检查它自己的权限，以排除错误的一个原因 .

  • 如果有错误，或者机器人本身的权限无效，机器人应该说些什么，对吗？

  • 需要实现某些东西以防止机器人尝试在DM或组上下文中使用此命令 . 它几乎总是错误的 .

  我提出以下解决方案（假设您使用命令扩展名）：

  import discord
  from discord.ext import commands
  import time
  @bot.command(pass_context=True,description="Kicks the given member. Please ensure both the bot and the command invoker have the permission 'Kick Members' before running this command.")
  async def kick(ctx, target:discord.Member):
      """(GUILD ONLY) Boot someone outta the server. See 's!kick' for more."""
      if not str(ctx.message.channel).startswith("Direct Message with "):
          msg=await bot.say("Checking perms...")
          time.sleep(0.5)
          if ctx.message.server.me.server_permissions.kick_members:
              if ctx.message.author.server_permissions.kick_members:
                  await bot.edit_message(msg,new_content="All permissions valid, checking issues with target...")
                  time.sleep(0.5)
                  if target==ctx.message.server.owner:
                      await bot.edit_message(msg, new_content="All permissions are correct, but you're attempting to kick the server owner, whom you can't kick no matter how hard you try. Whoops!")
                  else:
                      if target==ctx.message.server.me:
                          await bot.edit_message(msg, new_content="Whoops! All permissions are corrent, but you just tried to make me kick myself, which is not possible. Perhaps you meant someone else, not poor me?")
                      else:
                          await bot.edit_message(msg, new_content="All permissions correct, and no issues with target being self or server owner, attempting to kick.")
                          time.sleep(2)
                          try:
                              await bot.kick(target)
                              await bot.edit_message(msg, ":boom: BAM! ***kicc'd***")
                          except Exception:
                              await bot.edit_message(msg, new_content="I was unable to kick the passed member. The member may have a higher role than me, I may have crashed into a rate-limit, or an unknown error may have occured. In that case, try again.")
              else:
                  await bot.edit_message(msg, new_content="I've the correct permissions, {}, but you do not. Perhaps ask for them?").format(ctx.message.author.mention)
          else:
              await bot.edit_message(msg, new_content="I'm just a poor bot with no permissions. Could you kindly grant me the permission `Kick Members`? Thanks! :slight_smile:")
      else:
          await bot.say("'Tis a DM! This command is for servers only... try this again in a server maybe? :slight_smile:")
