+以下是比较重要的编写与排版规范。目前 NoneBot2 文档中仍有部分文档不完全遵守此规范，如果在阅读时发现欢迎提交 PR。
 
 1. 中文与英文、数字、半角符号之间需要有空格。例：`NoneBot2 是一个可扩展的 Python 异步机器人框架。`
 2. 若非英文整句，使用全角标点符号。例：`现在你可以看到机器人回复你：“Hello, World !”。`
 3. 直引号`「」`和弯引号`“”`都可接受，但同一份文件里应使用同种引号。
 4. **不要使用斜体**，你不需要一种与粗体不同的强调。除此之外，你也可以考虑使用 docusaurus 提供的[告示](https://docusaurus.io/zh-CN/docs/markdown-features/admonitions)功能。
+5. 文档中应以“我们”指代机器人开发者，以“机器人用户”指代机器人的使用者。

 #### 什么是依赖注入
 
-[**“依赖注入”**](https://zh.m.wikipedia.org/wiki/%E6%8E%A7%E5%88%B6%E5%8F%8D%E8%BD%AC)意思是，在编程中，有一种方法可以让你的代码声明它工作和使用所需要的东西，即**“依赖”**。

-系统（在这里是指 NoneBot2）将负责做任何需要的事情，为你的代码提供这些必要依赖（即**“注入”**依赖性）
+系统（在这里是指 NoneBot）将负责做任何需要的事情，为你的代码提供这些必要依赖（即**『注入』**依赖性）
 
 这在你有以下情形的需求时非常有用：
 
 - 这部分代码拥有共享的逻辑（同样的代码逻辑多次重复）
 - 共享数据库以及网络请求连接会话
   - 比如 `httpx.AsyncClient`、`aiohttp.ClientSession` 和 `sqlalchemy.Session`
-- 用户权限检查以及认证
+- 机器人用户权限检查以及认证
 - 还有更多...
 
 它在完成上述工作的同时，还能尽量减少代码的耦合和重复

-## 它如何工作？
-
-如同[概览](../README.md)所言：
-
-> NoneBot2 是一个可扩展的 Python 异步机器人框架，它会对机器人收到的事件进行解析和处理，并以插件化的形式，按优先级分发给事件所对应的事件响应器，来完成具体的功能。
-
-NoneBot2 是一个可以对机器人上报的事件进行处理并完成具体功能的机器人框架，在这里，我们将简要讲述它的工作内容。
-
-**便捷起见，以下内容对 NoneBot2 会被称为 NoneBot，与 NoneBot2 交互的机器人实现会被称为协议端**。
-
-在实际应用中，NoneBot 会充当一个高性能，轻量级的 Python 微服务框架。协议端可以通过 http、websocket 等方式与之通信，这个通信往往是双向的：一方面，协议端可以上报数据给 NoneBot，NoneBot 会处理数据并返回响应给协议端；另一方面，NoneBot 可以主动推送数据给协议端。而 NoneBot 便是围绕双向通信进行工作的。
-
-在开始工作之前，NoneBot 需要进行准备工作：
-
-1. **运行 `nonebot.init` 初始化函数**，它会读取配置文件，并初始化 NoneBot 和后端驱动 `Driver` 对象。
-2. **注册协议适配器 `Adapter`**。
-3. **加载插件**。
-
-准备工作完成后，NoneBot 会利用 uvicorn 启动，并运行 `on_startup` 钩子函数。
-
-随后，倘若一个协议端与 NoneBot 进行了连接，NoneBot 的后端驱动 `Driver` 就会将数据交给 `Adapter`，然后会实例化 `Bot`，NoneBot 便会利用 `Bot` 开始工作，它的工作内容分为两个方面：
-
-1. **事件处理**，`Bot` 会将协议端上报的数据转化为 `Event`（事件），之后 NoneBot 会根据一套既定流程来处理事件。
-
-2. **调用 `API`**，在**事件处理**的过程中，NoneBot 可以通过 `Bot` 调用协议端指定的 `API` 来获取更多数据，或者反馈响应给协议端；NoneBot 也可以通过调用 `API` 向协议端主动请求数据或者主动推送数据。
-
-在**指南**模块，我们已经叙述了[如何配置 NoneBot](../tutorial/configuration.md)、[如何注册协议适配器](../tutorial/register-adapter.md)以及[如何加载插件](../tutorial/plugin/load-plugin.md)，这里便不再赘述。
-
-下面，我们将对**事件处理**，**调用 API** 进行说明。
-
-## 事件处理
-
-我们可以先看事件处理的流程图：
-
-![handle-event](./images/Handle-Event.png)
-
-在流程图里，我们可以看到，NoneBot 会有三个阶段来处理事件：
-
-1. **Driver 接收上报数据**
-2. **Adapter 处理原始数据**
-3. **NoneBot 处理 Event**
-
-我们将顺序说明这三个阶段。其中，会将第三个阶段拆分成**概念解释**，**处理 Event**，**特殊异常处理**三个部分来说明。
-
-### Driver 接收上报数据
-
-1. 协议端会通过 websocket 或 http 等方式与 NoneBot 的后端驱动 `Driver` 连接，协议端上报数据后，`Driver` 会将原始数据交给 `Adapter` 处理。
-
-:::warning
-连接之前必须要注册 `Adapter`
-:::
-
-### Adapter 处理原始数据
-
-1. `Adapter` 检查授权许可，并获取 `self-id` 作为唯一识别 id 。
-
-:::tip
-如果协议端通过 websocket 上报数据，这个步骤只会在建立连接时进行，并在之后运行 `on_bot_connect` 钩子函数；通过 http 方式连接时，会在协议端每次上报数据时都进行这个步骤。
-:::
-
-:::warning
-`self-id` 是帐号的唯一识别 ID ，这意味着不能出现相同的 `self-id`。
-:::
-
-2. 根据 `self-id` 实例化 `Adapter` 相应的 `Bot` 。
-
-3. 根据 `Event Model` 将原始数据转化为 NoneBot 可以处理的 `Event` 对象。
-
-:::tip
-`Adapter` 在转换数据格式的同时可以进行一系列的特殊操作，例如 OneBot 适配器会对 reply 信息进行提取。
-:::
-
-4. `Bot` 和 `Event` 交由 NoneBot 进一步处理。
-
-### NoneBot 处理 Event
-
-在讲述这个阶段之前，我们需要先对几个概念进行解释。
-
-#### 概念解释
-
-1. **hook** ，或者说**钩子函数**，它们可以在 NoneBot 处理 `Event` 的不同时刻进行拦截，修改或者扩展，在 NoneBot 中，事件钩子函数分为`事件预处理 hook`、`运行预处理 hook`、`运行后处理 hook` 和`事件后处理 hook`。
-
-:::tip
-关于 `hook` 的更多信息，可以查阅[这里](./runtime-hook.md)。
-:::
-
-2. **Matcher** 与 **matcher**，在**指南**中，我们讲述了[如何注册事件响应器](../tutorial/plugin/create-matcher.md)，这里的事件响应器或者说 `Matcher` 并不是一个具体的实例 `instance`，而是一个具有特定属性的类 `class`。只有当 `Matcher` **响应事件**时，才会实例化为具体的 `instance`，也就是 `matcher` 。`matcher` 可以认为是 NoneBot 处理 `Event` 的基本单位，运行 `matcher` 是 NoneBot 工作的主要内容。
-
-3. **handler**，或者说**事件处理函数**，它们可以认为是 NoneBot 处理 `Event` 的最小单位。在不考虑 `hook` 的情况下，**运行 matcher 就是顺序运行 matcher.handlers**，这句话换种表达方式就是，`handler` 只有添加到 `matcher.handlers` 时，才可以参与到 NoneBot 的工作中来。
-
-:::tip
-如何让 `handler` 添加到 `matcher.handlers`？
-
-一方面，我们可以参照[这里](../tutorial/plugin/create-handler.md)利用装饰器来添加；另一方面，我们在用 `on()` 或者 `on_*()` 注册事件响应器时，可以添加 `handlers=[handler1, handler2, ...]` 这样的关键词参数来添加。
-:::
-
-#### 处理 Event
-
-1. **执行事件预处理 hook**， NoneBot 接收到 `Event` 后，会传入到 `事件预处理 hook` 中进行处理。
-
-:::warning
-需要注意的是，执行多个 `事件预处理 hook` 时并无顺序可言，它们是**并发运行**的。这个原则同样适用于其他的 `hook`。
-:::
-
-2. **按优先级升序选出同一优先级的 Matcher**，NoneBot 提供了一个全局字典 `matchers`，这个字典的 `key` 是优先级 `priority`，`value` 是一个 `list`，里面存放着同一优先级的 `Matcher`。在注册 `Matcher` 时，它和优先级 `priority` 会添加到里面。
-
-   在执行 `事件预处理 hook` 后，NoneBot 会对 `matchers` 的 `key` 升序排序并选择出当前最小优先级的 `Matcher`。
-
-3. **根据 Matcher 定义的 Rule、Permission 判断是否运行**，在选出 `Matcher` 后，NoneBot 会将 `bot`，`Event` 传入到 `Matcher.check_rule` 和 `Matcher.check_perm` 两个函数中，两个函数分别对 Matcher 定义的 `Rule`、`Permission` 进行 check，当 check 通过后，这个 `Matcher` 就会响应事件。当同一个优先级的所有 `Matcher` 均没有响应时，NoneBot 会返回到上一个步骤，选择出下一优先级的 `Matcher`。
-
-4. **实例化 matcher 并执行运行预处理 hook**，当 `Matcher` 响应事件后，它便会实例化为 `matcher`，并执行 `运行预处理 hook`。
-
-5. **顺序运行 matcher 的所有 handlers**，`运行预处理 hook` 执行完毕后，便会运行 `matcher`，也就是**顺序运行**它的 `handlers`。
-
-:::tip
-`matcher` 运行 `handlers` 的顺序是：先运行该 `matcher` 的类 `Matcher` 注册时添加的 `handlers`(如果有的话)，再按照装饰器装饰顺序运行装饰的 `handlers`。
-:::
-
-6. **执行运行后处理 hook**，`matcher` 的 `handlers` 运行完毕后，会执行 `运行后处理 hook`。
-
-7. **判断是否停止事件传播**，NoneBot 会根据当前优先级所有 `matcher` 的 `block` 参数或者 `StopPropagation` 异常判断是否停止传播 `Event`，如果事件没有停止传播，NoneBot 便会返回到第 2 步， 选择出下一优先级的 `Matcher`。
-
-8. **执行事件后处理 hook**，在 `Event` 停止传播或执行完所有响应的 `Matcher` 后，NoneBot 会执行 `事件后处理 hook`。
-
-   当 `事件后处理 hook` 执行完毕后，当前 `Event` 的处理周期就顺利结束了。
-
-#### 特殊异常处理
-
-在这个阶段，NoneBot 规定了几个特殊的异常，当 NoneBot 捕获到它们时，会用特定的行为来处理它们。
-
-1. **IgnoredException**
-
-   这个异常可以在 `事件预处理 hook` 和 `运行预处理 hook` 抛出。
-
-   当 `事件预处理 hook` 抛出它时，NoneBot 会忽略当前的 `Event`，不进行处理。
-
-   当 `运行预处理 hook` 抛出它时，NoneBot 会忽略当前的 `matcher`，结束当前 `matcher` 的运行。
-
-:::warning
-当 `hook` 需要抛出这个异常时，要写明原因。
-:::
-
-2. **PausedException**
-
-   这个异常可以在 `handler` 中由 `Matcher.pause` 抛出。
-
-   当 NoneBot 捕获到它时，会停止运行当前 `handler` 并结束当前 `matcher` 的运行，并将后续的 `handler` 交给一个临时 `Matcher` 来响应当前交互用户的下一个消息事件，当临时 `Matcher` 响应时，临时 `Matcher` 会运行后续的 `handler`。
-
-3. **RejectedException**
-
-   这个异常可以在 `handler` 中由 `Matcher.reject` 抛出。
-
-   当 NoneBot 捕获到它时，会停止运行当前 `handler` 并结束当前 `matcher` 的运行，并将当前 handler 和后续 `handler` 交给一个临时 `Matcher` 来响应当前交互用户的下一个消息事件，当临时 `Matcher` 响应时，临时 `Matcher` 会运行当前 `handler` 和后续的 `handler` 。
-
-4. **FinishedException**
-
-   这个异常可以在 `handler` 中由 `Matcher.finish` 抛出。
-
-   当 NoneBot 捕获到它时，会停止运行当前 `handler` 并结束当前 `matcher` 的运行。
-
-5. **StopPropagation**
-
-   这个异常一般会在执行 `运行后处理 hook` 后抛出。
-
-   当 NoneBot 捕获到它时， 会停止传播当前 `Event` ，不再寻找下一优先级的 `Matcher` ，直接执行 `事件后处理 hook` 。
-
-## 调用 API
-
-NoneBot 可以通过 `bot` 来调用 `API`，`API` 可以向协议端发送数据，也可以向协议端请求更多的数据。
-
-NoneBot 调用 `API` 会有如下过程：
-
-1. 调用 `calling_api_hook` 预处理钩子。
-
-2. `adapter` 将信息处理为原始数据，并转交 `driver`，`driver` 交给协议端处理。
-
-3. `driver` 接收协议端的结果，交给`adapter` 处理之后将结果反馈给 NoneBot 。
-
-4. 调用 `called_api_hook` 后处理钩子。
-
-在调用 `API` 时同样规定了特殊的异常，叫做 `MockApiException` 。该异常会由预处理钩子和后处理钩子触发，当预处理钩子触发时，NoneBot 会跳过之后的调用过程，直接执行后处理钩子。
-
-:::tip
-不同 `adapter` 规定了不同的 API，对应的 API 列表请参照协议规范。
-:::
-
-一般来说，我们可以用 `bot.*` 来调用 `API`（\*是 `API` 的 `action` 或者 `endpoint`）。
-
-对于发送消息而言，一方面可以调用既有的 `API` ；另一方面 NoneBot 实现了两个便捷方法，`bot.send(event, message, **kwargs)` 方法和可以在 `handler` 中使用的 `Matcher.send(message, **kwargs)` 方法，来向事件主体发送消息。

+---
+
+# 使用适配器
+
+适配器 (Adapter) 是机器人与平台交互的核心桥梁，它负责在驱动器和机器人插件之间转换与传递消息。
+
+## 适配器功能与组成
+
+适配器通常有两种功能，分别是**接收事件**和**调用平台接口**。其中，接收事件是指将驱动器收到的事件消息转换为 NoneBot 定义的事件模型，然后交由机器人插件处理；调用平台接口是指将机器人插件调用平台接口的数据转换为平台指定的格式，然后交由驱动器发送，并接收接口返回数据。
+
+为了实现这两种功能，适配器通常由四个部分组成：
+
+- **Adapter**：负责转换事件和调用接口，正确创建 Bot 对象并注册到 NoneBot 中。
+- **Bot**：负责存储平台机器人相关信息，并提供回复事件的方法。
+- **Event**：负责定义事件内容，以及事件主体对象。
+- **Message**：负责正确序列化消息，以便机器人插件处理。
+
+## 注册适配器
+
+在使用适配器之前，我们需要先将适配器注册到驱动器中，这样适配器就可以通过驱动器接收事件和调用接口了。我们以 Console 适配器为例，来看看如何注册适配器：
+
+```python {2,5} title=bot.py
+import nonebot
+from nonebot.adapters.console import Adapter
+
+driver = nonebot.get_driver()
+driver.register_adapter(Adapter)
+```
+
+我们首先需要从适配器模块中导入所需要的适配器类，然后通过驱动器的 `register_adapter` 方法将适配器注册到驱动器中即可。如果我们需要多平台支持，可以多次调用 `register_adapter` 方法来注册多个适配器。
+
+## 获取已注册的适配器
+
+NoneBot 提供了 `get_adapter` 方法来获取已注册的适配器，我们可以通过适配器的名称或类型来获取指定的适配器实例：
+
+```python
+import nonebot
+from nonebot.adapters.console import Adapter
+
+adapters = nonebot.get_adapters()
+console_adapter = nonebot.get_adapter(Adapter)
+console_adapter = nonebot.get_adapter(Adapter.get_name())
+```
+
+## 获取 Bot 对象
+
+当前所有适配器已连接的 Bot 对象可以通过 `get_bots` 方法获取，这是一个以机器人 ID 为键的字典：
+
+```python
+import nonebot
+
+bots = nonebot.get_bots()
+```
+
+我们也可以通过 `get_bot` 方法获取指定 ID 的 Bot 对象。如果省略 ID 参数，将会返回所有 Bot 中的第一个：
+
+```python
+import nonebot
+
+bot = nonebot.get_bot("bot_id")
+```
+
+如果需要获取指定适配器连接的 Bot 对象，我们可以通过适配器的 `bots` 属性获取，这也是一个以机器人 ID 为键的字典：
+
+```python
+import nonebot
+from nonebot.adapters.console import Adapter
+
+console_adapter = nonebot.get_adapter(Adapter)
+bots = console_adapter.bots
+```
+
+Bot 对象都具有一个 `self_id` 属性，它是机器人的唯一 ID，由适配器填写，通常为机器人的帐号 ID 或者 APP ID。
+
+## 获取事件通用信息
+
+适配器的所有事件模型均继承自 `Event` 基类，在[事件类型与重载](../appendices/overload.md)一节中，我们也提到了如何使用基类抽象方法来获取事件通用信息。基类能提供如下信息：
+
+### 事件类型
+
+事件类型通常为 `meta_event`、`message`、`notice`、`request`。
+
+```python
+type: str = event.get_type()
+```
+
+### 事件名称
+
+事件名称由适配器定义，通常用于日志记录。
+
+```python
+name: str = event.get_event_name()
+```
+
+### 事件描述
+
+事件描述由适配器定义，通常用于日志记录。
+
+```python
+description: str = event.get_event_description()
+```
+
+### 事件日志字符串
+
+事件日志字符串由事件名称和事件描述组成，用于日志记录。
+
+```python
+log: str = event.get_log_string()
+```
+
+### 事件主体 ID
+
+事件主体 ID 通常为机器人用户 ID。
+
+```python
+user_id: str = event.get_user_id()
+```
+
+### 事件会话 ID
+
+事件会话 ID 通常为机器人用户 ID 与群聊/频道 ID 组合而成。
+
+```python
+session_id: str = event.get_session_id()
+```
+
+### 事件消息
+
+如果事件包含消息，则可以通过该方法获取，否则会产生异常。
+
+```python
+message: Message = event.get_message()
+```
+
+### 事件纯文本消息
+
+通常为事件消息的纯文本内容，如果事件不包含消息，则会产生异常。
+
+```python
+text: str = event.get_plaintext()
+```
+
+### 事件是否与机器人有关
+
+由适配器实现的判断，通常将事件目标主体为机器人、消息中包含“@机器人”或以“机器人的昵称”开始视为与机器人有关。
+
+```python
+is_tome: bool = event.is_tome()
+```
+
+## 更多
+
+官方支持的适配器和社区贡献的适配器均可在[商店](/store)中查看。如果你想要开发自己的适配器，可以参考[开发文档](../developer/adapter-writing.md)。欢迎通过商店发布你的适配器。

-# 简介
-
-受 [FastAPI](https://fastapi.tiangolo.com/tutorial/dependencies/) 启发，NoneBot 同样编写了一个简易的依赖注入模块，使得开发者可以通过事件处理函数参数的类型标注来自动注入依赖。
-
-## 什么是依赖注入？
-
-[依赖注入](https://zh.wikipedia.org/wiki/%E4%BE%9D%E8%B5%96%E6%B3%A8%E5%85%A5)
-
-> 在软件工程中，**依赖注入**（dependency injection）的意思为，给予调用方它所需要的事物。 “依赖”是指可被方法调用的事物。依赖注入形式下，调用方不再直接使用“依赖”，取而代之是“注入” 。“注入”是指将“依赖”传递给调用方的过程。在“注入”之后，调用方才会调用该“依赖。 传递依赖给调用方，而不是让让调用方直接获得依赖，这个是该设计的根本需求。
-
-依赖注入往往起到了分离依赖和调用方的作用，这样一方面能让代码更为整洁可读，一方面可以提升代码的复用性。
-
-## 使用依赖注入
-
-以下通过一个简单的例子来说明依赖注入的使用方法：
-
-```python {2,7-8,11}
-from nonebot import on_command
-from nonebot.params import Depends # 1.引用 Depends
-from nonebot.adapters.onebot.v11 import MessageEvent
-
-test = on_command("123")
-
-async def depend(event: MessageEvent): # 2.编写依赖函数
-    return {"uid": event.get_user_id(), "nickname": event.sender.nickname}
-
-@test.handle()
-async def _(x: dict = Depends(depend)): # 3.在事件处理函数里声明依赖项
-    print(x["uid"], x["nickname"])
-```
-
-如注释所言，可以用三步来说明依赖注入的使用过程：
-
-1. 引用 `Depends` 。
-
-2. 编写依赖函数。依赖函数和普通的事件处理函数并无区别，同样可以接收 `bot`, `event`, `state` 等参数，你可以把它当作一个普通的事件处理函数，但是去除了装饰器（没有使用 `matcher.handle()` 等来装饰），并且可以返回任何类型的值。
-
-   在这里我们接受了 `event`，并以 `onebot` 的 `MessageEvent` 作为类型标注，返回一个新的字典，包括 `uid` 和 `nickname` 两个键值。
-
-3. 在事件处理函数中声明依赖项。依赖项必须要 `Depends` 包裹依赖函数作为默认值。
-
-:::tip
-请注意，参数 `x` 的类型标注将会影响到事件处理函数的运行，与类型标注不符的值将会导致事件处理函数被跳过。
-:::
-
-:::tip
-事实上，bot、event、state 它们本身只是依赖注入的一个特例，它们无需声明这是依赖即可注入。
-:::
-
-虽然声明依赖项的方式和其他参数如 `bot`, `event` 并无二样，但他的参数有一些限制，必须是**可调用对象**，函数自然是可调用对象，类和生成器也是，我们会在接下来的小节说明。
-
-一般来说，当接收到事件时，`NoneBot2` 会进行以下处理：
-
-1. 准备依赖函数所需要的参数。
-2. 调用依赖函数并获得返回值。
-3. 将返回值作为事件处理函数中的参数值传入。
-
-## 依赖缓存
-
-在使用 `Depends` 包裹依赖函数时，有一个参数 `use_cache` ，它默认为 `True` ，这个参数会决定 `Nonebot2` 在依赖注入的处理中是否使用缓存。
-
-```python {11}
-import random
-from nonebot import on_command
-from nonebot.params import Depends
-
-test = on_command("123")
-
-async def always_run():
-    return random.randint(1, 100)
-
-@test.handle()
-async def _(x: int = Depends(always_run, use_cache=False)):
-    print(x)
-```
-
-:::tip
-缓存是针对单次事件处理来说的，在事件处理中 `Depends` 第一次被调用时，结果存入缓存，在之后都会直接返回缓存中的值，在事件处理结束后缓存就会被清除。
-:::
-
-当使用缓存时，依赖注入会这样处理：
-
-1. 查询缓存，如果缓存中有相应的值，则直接返回。
-2. 准备依赖函数所需要的参数。
-3. 调用依赖函数并获得返回值。
-4. 将返回值存入缓存。
-5. 将返回值作为事件处理函数中的参数值传入。
-
-## 同步支持
-
-我们在编写依赖函数时，可以简单地用同步函数，`NoneBot2` 的内部流程会进行处理：
-
-```python {2,8-9,12}
-from nonebot.log import logger
-from nonebot.params import Depends # 1.引用 Depends
-from nonebot import on_command, on_message
-from nonebot.adapters.onebot.v11 import MessageEvent
-
-test = on_command("123")
-
-def depend(event: MessageEvent): # 2.编写同步依赖函数
-    return {"uid": event.get_user_id(), "nickname": event.sender.nickname}
-
-@test.handle()
-async def _(x: dict = Depends(depend)): # 3.在事件处理函数里声明依赖项
-    print(x["uid"], x["nickname"])
-```
-
-## Class 作为依赖
-
-我们可以看下面的代码段：
-
-```python
-class A:
-    def __init__(self):
-        pass
-a = A()
-```
-
-在我们实例化类 `A` 的时候，其实我们就在**调用**它，类本身也是一个**可调用对象**，所以类可以被 `Depends` 包裹成为依赖项。
-
-因此我们对第一节的代码段做一下改造：
-
-```python {2,7-10,13}
-from nonebot import on_command
-from nonebot.params import Depends # 1.引用 Depends
-from nonebot.adapters.onebot.v11 import MessageEvent
-
-test = on_command("123")
-
-class DependClass: # 2.编写依赖类
-    def __init__(self, event: MessageEvent):
-        self.uid = event.get_user_id()
-        self.nickname = event.sender.nickname
-
-@test.handle()
-async def _(x: DependClass = Depends(DependClass)): # 3.在事件处理函数里声明依赖项
-    print(x.uid, x.nickname)
-```
-
-依然可以用三步说明如何用类作为依赖项：
-
-1. 引用 `Depends` 。
-2. 编写依赖类。类的 `__init__` 函数可以接收 `bot`, `event`, `state` 等参数，在这里我们接受了 `event`，并以 `onebot` 的 `MessageEvent` 作为类型标注。
-3. 在事件处理函数中声明依赖项。当用类作为依赖项时，它会是一个对应的实例，在这里 `x` 就是 `DependClass` 实例。
-
-### 另一种依赖项声明方式
-
-当使用类作为依赖项时，`Depends` 的参数可以为空，`NoneBot2` 会根据参数的类型标注进行推断并进行依赖注入。
-
-```python
-@test.handle()
-async def _(x: DependClass = Depends()): # 在事件处理函数里声明依赖项
-    print(x.uid, x.nickname)
-```
-
-## 生成器作为依赖
-
-:::warning
-`yield` 语句只能写一次，否则会引发异常。
-如果对此有疑问并想探究原因，可以看 [contextmanager](https://docs.python.org/zh-cn/3/library/contextlib.html#contextlib.contextmanager) 和 [asynccontextmanager](https://docs.python.org/zh-cn/3/library/contextlib.html#contextlib.asynccontextmanager) 文档，实际上，`Nonebot2` 的内部就使用了这两个装饰器。
-:::
-
-:::tips
-生成器是 `Python` 高级特性，如果你对此处文档感到疑惑那说明暂时你还用不上这个功能。
-:::
-
-与 `FastAPI` 一样，`NoneBot2` 的依赖注入支持依赖项在事件处理结束后进行一些额外的工作，比如数据库 session 或者网络 IO 的关闭，互斥锁的解锁等等。
-
-要实现上述功能，我们可以用生成器函数作为依赖项，我们用 `yield` 关键字取代 `return` 关键字，并在 `yield` 之后进行额外的工作。
-
-我们可以看下述代码段, 使用 `httpx.AsyncClient` 异步网络 IO：
-
-```python {3,7-10,13}
-import httpx
-from nonebot import on_command
-from nonebot.params import Depends # 1.引用 Depends
-
-test = on_command("123")
-
-async def get_client(): # 2.编写异步生成器函数
-    async with httpx.AsyncClient() as client:
-        yield client
-    print("调用结束")
-
-@test.handle()
-async def _(x: httpx.AsyncClient = Depends(get_client)): # 3.在事件处理函数里声明依赖项
-    resp = await x.get("https://v2.nonebot.dev")
-    # do something
-```
-
-我们用 `yield` 代码段作为生成器函数的“返回”，在事件处理函数里用返回出来的 `client` 做自己需要的工作。在 `NoneBot2` 结束事件处理时，会执行 `yield` 之后的代码。
-
-## 创造可调用对象作为依赖
-
-:::tips
-魔法方法 `__call__` 是 `Python` 高级特性，如果你对此处文档感到疑惑那说明暂时你还用不上这个功能。
-:::
-
-在 `Python` 的里，类的 `__call__` 方法会让类的实例变成**可调用对象**，我们可以利用这个魔法方法做一个简单的尝试：
-
-```python{3,9-14,16,19}
-from typing import Type
-from nonebot.log import logger
-from nonebot.params import Depends # 1.引用 Depends
-from nonebot import on_command
-from nonebot.adapters.onebot.v11 import MessageEvent, GroupMessageEvent
-
-test = on_command("123")
-
-class EventChecker: # 2.编写需要的类
-    def __init__(self, EventClass: Type[MessageEvent]):
-        self.event_class = EventClass
-
-    def __call__(self, event: MessageEvent) -> bool:
-        return isinstance(event, self.event_class)
-
-checker = EventChecker(GroupMessageEvent) # 3.将类实例化
-
-@test.handle()
-async def _(x: bool = Depends(checker)): # 4.在事件处理函数里声明依赖项
-    if x:
-        print("这是群聊消息")
-    else:
-        print("这不是群聊消息")
-```
-
-这是判断 `onebot` 的消息事件是不是群聊消息事件的一个例子，我们可以用四步来说明这个例子：
-
-1. 引用 `Depends` 。
-2. 编写需要的类。类的 `__init__` 函数接收参数 `EventClass`，它将接收事件类本身。类的 `__call__` 函数将接受消息事件对象，并返回一个 `bool` 类型的判定结果。
-3. 将类实例化。我们传入群聊消息事件作为参数实例化 `checker` 。
-4. 在事件处理函数里声明依赖项。`NoneBot2` 将会调用 `checker` 的 `__call__` 方法，返回给参数 `x` 相应的判断结果。
