## Внедрить текущего пользователя { #inject-the-current-user }

Теперь мы можем использовать тот же `Depends` с нашей `get_current_user` в *операции пути*:

{* ../../docs_src/security/tutorial002_an_py310.py hl[31] *}

Обратите внимание, что мы объявляем тип `current_user` как Pydantic-модель `User`.

    然后，依赖项函数返回包含这些值的 `dict`。

### 导入 `Depends`

{* ../../docs_src/dependencies/tutorial001.py hl[3] *}

### 声明依赖项

与在*路径操作函数*参数中使用 `Body`、`Query` 的方式相同，声明依赖项需要使用 `Depends` 和一个新的参数：

{* ../../docs_src/dependencies/tutorial001.py hl[15,20] *}

虽然，在路径操作函数的参数中使用 `Depends` 的方式与 `Body`、`Query` 相同，但 `Depends` 的工作方式略有不同。

这里只能传给 Depends 一个参数。

且该参数必须是可调用对象，比如函数。

该函数接收的参数和*路径操作函数*的参数一样。

    ///

{* ../../docs_src/security/tutorial005.py hl[4,139,166] *}

/// info | 技术细节

`Security` 实际上是 `Depends` 的子类，而且只比 `Depends` 多一个参数。

但使用 `Security` 代替 `Depends`，**FastAPI** 可以声明安全作用域，并在内部使用这些作用域，同时，使用 OpenAPI 存档 API。

但实际上，从 `fastapi` 导入的 `Query`、`Path`、`Depends`、`Security` 等对象，只是返回特殊类的函数。

///

## 使用 `SecurityScopes`

修改依赖项 `get_current_user`。

这是上面的依赖项使用的依赖项。

## Inyectar al usuario actual { #inject-the-current-user }

Entonces ahora podemos usar el mismo `Depends` con nuestro `get_current_user` en la *path operation*:

{* ../../docs_src/security/tutorial002_an_py310.py hl[31] *}

Ten en cuenta que declaramos el tipo de `current_user` como el modelo de Pydantic `User`.

And all of them will use the same WebSocket connection.

## Using `Depends` and others { #using-depends-and-others }

In WebSocket endpoints you can import from `fastapi` and use:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

They work the same way as for other FastAPI endpoints/*path operations*:

이렇게 하면 `checker.fixed_content` 속성에 `"bar"`라는 값을 담아 의존성을 "매개변수화"할 수 있습니다.

## 인스턴스를 의존성으로 사용하기

그런 다음, `Depends(FixedContentQueryChecker)` 대신 `Depends(checker)`에서 이 `checker` 인스턴스를 사용할 수 있으며,
클래스 자체가 아닌 인스턴스 `checker`가 의존성이 됩니다.

의존성을 해결할 때 **FastAPI**는 이 `checker`를 다음과 같이 호출합니다:

```Python
checker(q="somequery")
```

    ## 创建实例

使用以下代码创建类实例：

{* ../../docs_src/dependencies/tutorial011.py hl[16] *}

这样就可以**参数化**依赖项，它包含 `checker.fixed_content` 的属性 - `"bar"`。

## 把实例作为依赖项

然后，不要再在 `Depends(checker)` 中使用 `Depends(FixedContentQueryChecker)`， 而是要使用 `checker`，因为依赖项是类实例 - `checker`，不是类。

处理依赖项时，**FastAPI** 以如下方式调用 `checker`：

```Python
checker(q="somequery")
```

……并用*路径操作函数*的参数 `fixed_content_included` 返回依赖项的值：
