And we can add a list of `dependencies` that will be added to all the *path operations* in the router and will be executed/solved for each request made to them.

/// tip

Note that, much like [dependencies in *path operation decorators*](dependencies/dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, no value will be passed to your *path operation function*.

但该异常将会被 `unicorn_exception_handler` 处理。

接收到的错误信息清晰明了，HTTP 状态码为 `418`，JSON 内容如下：

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}

```

/// note | 技术细节

`from starlette.requests import Request` 和 `from starlette.responses import JSONResponse` 也可以用于导入 `Request` 和 `JSONResponse`。

            context = new EncryptionNegotiateContext(mockConfig, ciphers);
            int encoded = context.encode(buffer, 0);

            assertEquals(2 + (count * 2), encoded);
            // Note: size() returns 4 + count*2, but encode returns 2 + count*2

## メタデータの宣言

パラメータは`Query`と同じものを宣言することができます。

例えば、パスパラメータ`item_id`に対して`title`のメタデータを宣言するには以下のようにします:

{* ../../docs_src/path_params_numeric_validations/tutorial001.py hl[8] *}

/// note | 備考

パスの一部でなければならないので、パスパラメータは常に必須です。

そのため、`...`を使用して必須と示す必要があります。

それでも、`None`で宣言しても、デフォルト値を設定しても、何の影響もなく、常に必要とされていることに変わりはありません。

///

## 必要に応じてパラメータを並び替える

クエリパラメータ`q`を必須の`str`として宣言したいとしましょう。

В данном случае требуется scope `me` (их также могло быть больше одного).

/// note | Примечание

Вам не обязательно добавлять разные scopes в разных местах.

Мы делаем это здесь, чтобы показать, как **FastAPI** обрабатывает scopes, объявленные на разных уровнях.

///

E outra para autenticar e retornar um usuário.

{* ../../docs_src/security/tutorial004_an_py310.py hl[8,49,56:57,60:61,70:76] *}
