事件处理函数类型为 `Callable[[Bot, Event, State], Union[Awaitable[None], Awaitable[NoReturn]]]` 。

参数分别为:
|
||||
|

1. [nonebot.typing.Bot](../api/typing.md#bot): 即事件上报连接对应的 Bot 对象,为 BaseBot 的子类。特别注意,此处的类型注释可以替换为指定的 Bot 类型,例如:`nonebot.adapters.cqhttp.Bot`,只有在上报事件的 Bot 类型与类型注释相符时才会执行该处理函数!可用于多平台进行不同的处理。
|
||||
2. [nonebot.typing.Event](../api/typing.md#event): 即上报事件对象,可以获取到上报的所有信息。
|
||||
3. `state`: 状态字典,可以存储任意的信息,其中还包含一些特殊的值以获取 NoneBot 内部处理时的一些信息,如:

- `state["_current_key"]`: 存储当前 `got` 获取的参数名
|
