しかし、それでも実行・解決される必要があります。

そのような場合、`Depends` で *path operation 関数* のパラメータを宣言する代わりに、*path operation デコレータ*に `dependencies` の `list` を追加できます。

## *path operation デコレータ*に`dependencies`を追加 { #add-dependencies-to-the-path-operation-decorator }

*path operation デコレータ*はオプション引数`dependencies`を受け取ります。

それは`Depends()`の`list`であるべきです:

{* ../../docs_src/dependencies/tutorial006_an_py310.py hl[19] *}

But in the end, they are implementing the same OAuth2 standard.

///

**FastAPI** includes utilities for all these OAuth2 authentication flows in `fastapi.security.oauth2`.

## `Security` in decorator `dependencies` { #security-in-decorator-dependencies }

In OpenAPI wird folglich jede dieser HTTP-Methoden als „Operation“ bezeichnet.

Wir werden sie auch „**Operationen**“ nennen.

#### Definieren eines *Pfadoperation-Dekorators* { #define-a-path-operation-decorator }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[6] *}

{* ../../docs_src/first_steps/tutorial001_py310.py hl[6] *}

O `@app.get("/")` diz ao **FastAPI** que a função logo abaixo é responsável por tratar as requisições que vão para:

* o path `/`
* usando uma <dfn title="um método HTTP GET"><code>get</code> operação</dfn>

/// info | Informações sobre `@decorator`

 * should override one or more methods to modify the behavior of the backing multiset as desired per
 * the <a href="http://en.wikipedia.org/wiki/Decorator_pattern">decorator pattern</a>.
 *
 * <p><b>Warning:</b> The methods of {@code ForwardingSortedMultiset} forward
 * <b>indiscriminately</b> to the methods of the delegate. For example, overriding {@link

因此，在 OpenAPI 中，每一个 HTTP 方法都被称为「操作」。

我们也打算称呼它们为「操作」。

#### 定义一个*路径操作装饰器* { #define-a-path-operation-decorator }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[6] *}

`@app.get("/")` 告诉 **FastAPI** 在它下方的函数负责处理如下访问请求：

* 请求路径为 `/`
* 使用 <dfn title="一种 HTTP GET 方法"><code>get</code> 操作</dfn>

/// info | `@decorator` 信息

`@something` 语法在 Python 中被称为「装饰器」。

像一顶漂亮的装饰帽一样，将它放在一个函数的上方（我猜测这个术语的命名就是这么来的）。

 * A list which forwards all its method calls to another list. Subclasses should override one or
 * more methods to modify the behavior of the backing list as desired per the <a

 *
 * <p>This class does not implement {@link java.util.RandomAccess}. If the delegate supports random
 * access, the {@code ForwardingList} subclass should implement the {@code RandomAccess} interface.

## `model` ile Ek Response { #additional-response-with-model }

*Path operation decorator*'larınıza `responses` adlı bir parametre geçebilirsiniz.

Bu parametre bir `dict` alır: anahtarlar her response için status code'lardır (`200` gibi), değerler ise her birine ait bilgileri içeren başka `dict`'lerdir.
