 * Tester of subtyping relationships between two types.

 * <p>Tests should inherit from this class, and declare subtyping relationship with public methods

 * <p>These declaration methods rely on Java static type checking to make sure what we want to

Убедитесь, что вы [обновили версию FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} как минимум до 0.95.1 перед тем, как использовать `Annotated`.

///

## Определите метаданные { #declare-metadata }

Вы можете указать все те же параметры, что и для `Query`.

Например, чтобы указать значение метаданных `title` для path-параметра `item_id`, вы можете написать:

  echo 'If you have not, you will see a lot of undefined variable errors.'
else
  FROM_ENV=$(mktemp)
  # "export -p" prints a list of environment values in a safe-to-source format,
  # e.g. `declare -x TFCI_BAZEL_COMMON_ARGS="list of args"` for bash.
  export -p | grep TFCI > "$FROM_ENV"

  # Source the default ci values
  source ./ci/official/envs/ci_default

## Declare escopos em *operações de rota* e dependências { #declare-scopes-in-path-operations-and-dependencies }

Agora nós declaramos que a *operação de rota* para `/users/me/items/` exige o escopo `items`.

The `root_path` is used to handle these specific cases.

And it's also used internally when mounting sub-applications.

Having a proxy with a stripped path prefix, in this case, means that you could declare a path at `/app` in your code, but then, you add a layer on top (the proxy) that would put your **FastAPI** application under a path like `/api/v1`.

In this case, the original path `/app` would actually be served at `/api/v1/app`.

Tenha em mente que, neste caso, o FastAPI não verificará o conteúdo da lista.

Por exemplo, `list[int]` verificaria (e documentaria) que os conteúdos da lista são inteiros. Mas `list` sozinho não.

///

## Declare mais metadados { #declare-more-metadata }

Você pode adicionar mais informações sobre o parâmetro.

Essas informações serão incluídas no OpenAPI gerado e usadas pelas interfaces de documentação e por ferramentas externas.

Mas se você retornar uma `Response` diretamente (ou qualquer subclasse, como `JSONResponse`), os dados não serão convertidos automaticamente (mesmo que você declare um `response_model`), e a documentação não será gerada automaticamente (por exemplo, incluindo o "media type", no cabeçalho HTTP `Content-Type` como parte do esquema OpenAPI gerado).

## Dependency Injection { #dependency-injection }

Using `BackgroundTasks` also works with the dependency injection system, you can declare a parameter of type `BackgroundTasks` at multiple levels: in a *path operation function*, in a dependency (dependable), in a sub-dependency, etc.

## Поля-списки с параметром типа { #list-fields-with-type-parameter }

В Python есть специальный способ объявлять списки с внутренними типами, или «параметрами типа»:

### Объявите `list` с параметром типа { #declare-a-list-with-a-type-parameter }

Для объявления типов, у которых есть параметры типа (внутренние типы), таких как `list`, `dict`, `tuple`, передайте внутренний(ие) тип(ы) как «параметры типа», используя квадратные скобки: `[` и `]`
