python - 如何从不带参数 discord.py 的命令中获取服务器对象

Question

我正在尝试制作一个机器人，当我!info在 Python 上使用 discord.py 不向它传递任何参数时，它将在控制台中显示服务器信息。我发现的所有内容都涉及传递参数。

这是我迄今为止尝试过的：

@bot.command()
@asyncio.coroutine
def info(ctx):
    server = ctx.message.author.server
    server_name = server.name
    server_id = server.id
    server_owner = server.owner.name

    print("server name: {}"
          "server id: {}"
          "server owner: {}"
          .format(server_name, server_id, server_owner))

运行时，它会在控制台中显示：

Ignoring exception in command move
Traceback (most recent call last):
  File "D:\PycharmProjects\Movey\venv\lib\site-packages\discord\ext\commands\bot.py", line 846, in process_commands
    yield from command.invoke(ctx)
  File "D:\PycharmProjects\Movey\venv\lib\site-packages\discord\ext\commands\core.py", line 367, in invoke
    yield from self.prepare(ctx)
  File "D:\PycharmProjects\Movey\venv\lib\site-packages\discord\ext\commands\core.py", line 345, in prepare
    yield from self._parse_arguments(ctx)
  File "D:\PycharmProjects\Movey\venv\lib\site-packages\discord\ext\commands\core.py", line 304, in _parse_arguments
    transformed = yield from self.transform(ctx, param)
  File "D:\PycharmProjects\Movey\venv\lib\site-packages\discord\ext\commands\core.py", line 212, in transform
    raise MissingRequiredArgument('{0.name} is a required argument that is missing.'.format(param))
discord.ext.commands.errors.MissingRequiredArgument: ctx is a required argument that is missing.

你需要传递pass_context=True给@bot.command

@bot.command(pass_context=True)
@asyncio.coroutine
def info(ctx):
    server = ctx.message.author.server
    server_name = server.name
    server_id = server.id
    server_owner = server.owner.name

    print("server name: {}"
          "server id: {}"
          "server owner: {}"
          .format(server_name, server_id, server_owner))
