有時在你的路徑操作函式中，其實不需要某個依賴的回傳值。

或是該依賴根本沒有回傳值。

但你仍需要它被執行／解析。

這種情況下，你可以不在路徑操作函式的參數上使用 `Depends`，而是在路徑操作裝飾器加入一個 `dependencies` 的 `list`。

## 在路徑操作裝飾器加入 `dependencies` { #add-dependencies-to-the-path-operation-decorator }

路徑操作裝飾器可接受一個可選參數 `dependencies`。

它應該是由 `Depends()` 組成的 `list`：

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

 * <p>When calling {@link ScaleAndIndex#compute} (in {@linkplain ScaleAndIndexes#compute either
 * form}), the memory requirement is 8*N bytes for the copy of the dataset plus an overhead which is
 * independent of N (but depends on the quantiles being computed). When calling {@link
 * ScaleAndIndex#computeInPlace computeInPlace} (in {@linkplain ScaleAndIndexes#computeInPlace

such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it).  Whether that is true depends on what the Library does
and what the program that uses the Library does.

  1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that

또는 의존성이 값을 반환하지 않습니다.

그러나 여전히 실행/해결될 필요가 있습니다.

그런 경우에, `Depends`를 사용하여 *경로 처리 함수*의 매개변수로 선언하는 대신 *경로 처리 데코레이터*에 `dependencies`의 `list`를 추가할 수 있습니다.

## *경로 처리 데코레이터*에 `dependencies` 추가하기 { #add-dependencies-to-the-path-operation-decorator }

*경로 처리 데코레이터*는 선택적인 인자 `dependencies`를 받습니다.

`Depends()`로 된 `list`이어야 합니다:

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

有时，我们并不需要在*路径操作函数*中使用依赖项的返回值。

或者说，有些依赖项不返回值。

但仍要执行或解析该依赖项。

对于这种情况，不必在声明*路径操作函数*的参数时使用 `Depends`，而是可以在*路径操作装饰器*中添加一个由 `dependencies` 组成的 `list`。

## 在*路径操作装饰器*中添加 `dependencies` 参数 { #add-dependencies-to-the-path-operation-decorator }

*路径操作装饰器*支持可选参数 `dependencies`。

该参数的值是由 `Depends()` 组成的 `list`：

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

			// As per "Permission" section in
			// https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectGET.html
			// If the object you request does not exist,
			// the error Amazon S3 returns depends on
			// whether you also have the s3:ListBucket
			// permission.
			// * If you have the s3:ListBucket permission
			//   on the bucket, Amazon S3 will return an
			//   HTTP status code 404 ("no such key")

 * supported. Null keys and values are supported.
 *
 * <p>{@code containsKey(k)}, {@code put(k, v)} and {@code remove(k)} are all (expected and
 * amortized) constant time operations. Expected in the hashtable sense (depends on the hash
 * function doing a good job of distributing the elements to the buckets to a distribution not far
 * from uniform), and amortized since some operations can trigger a hash table resize.

Şu şekilde çağrılabilir:

```Python
oauth2_scheme(some, parameters)
```

Dolayısıyla `Depends` ile kullanılabilir.

### Kullanın { #use-it }

Artık `Depends` ile bir dependency olarak `oauth2_scheme`’i geçebilirsiniz.

{* ../../docs_src/security/tutorial001_an_py310.py hl[12] *}

tion="top",b.submitErrorMessageCallback=function(){return c}}}function e(b){var c=b.find("[data-validation-if-checked]");c.length&&a.formUtils.warn('Detected use of attribute "data-validation-if-checked" which is deprecated. Use "data-validation-depends-on" provided by module "logic"'),c.on("beforeValidation",function(){var c=a(this),d=c.valAttr("if-checked"),e=a('input[name="'+d+'"]',b),f=e.is(":checked"),g=(a.formUtils.getValue(e)||"").toString(),h=c.valAttr("if-checked-value");(!f||h&&h!==g)&...

Його можна викликати так:

```Python
oauth2_scheme(some, parameters)
```

Тож його можна використовувати з `Depends`.

### Використання { #use-it }

Тепер ви можете передати `oauth2_scheme` як залежність через `Depends`.

{* ../../docs_src/security/tutorial001_an_py310.py hl[12] *}

Ця залежність надасть `str`, який буде присвоєний параметру `token` *функції операції шляху*.
