## Объявление scopes в *обработчиках путей* и зависимостях { #declare-scopes-in-path-operations-and-dependencies }

Теперь объявим, что операция пути для `/users/me/items/` требует scope `items`.

Для этого импортируем и используем `Security` из `fastapi`.

如果你需要2分钟来学习如何使用 Python 类型（即使你不使用 FastAPI ），看看这个简短的教程：[Python Types](python-types.md){.internal-link target=_blank}。

编写带有类型标注的标准 Python：

```Python
from datetime import date

from pydantic import BaseModel

# Declare a variable as a str
# and get editor support inside the function
def main(user_id: str):
    return user_id


# A Pydantic model
class User(BaseModel):
    id: int
    name: str
    joined: date
```

 *  New: Publish a [bill of materials (BOM)][bom] for OkHttp. Depend on this from Gradle or Maven to
    keep all of your OkHttp artifacts on the same version, even if they're declared via transitive
    dependencies. You can even omit versions when declaring other OkHttp dependencies.

    ```kotlin
    dependencies {
       api(platform("com.squareup.okhttp3:okhttp-bom:4.4.0"))

     *       module path, but is also compatible with placement on the class path. Compatibility can
     *       be achieved, for example, by repeating in the {@code META-INF/services/} directory the services
     *       that are declared in the {@code module-info.class} file. In that case, the path type can be chosen
     *       by the plugin.</li>
     *   <li>If a {@link #patchModule(String)} is also set and the main JAR file is placed on the module path,

    return startIndex == endIndex
        ? EMPTY
        : new ImmutableLongArray(array, start + startIndex, start + endIndex);
  }

  @IgnoreJRERequirement // used only from APIs that use streams
  /*
   * We declare this as package-private, rather than private, to avoid generating a synthetic
   * accessor method (under -target 8) that would lack the Android flavor's @IgnoreJRERequirement.
   */
  Spliterator.OfLong spliterator() {

    return startIndex == endIndex
        ? EMPTY
        : new ImmutableIntArray(array, start + startIndex, start + endIndex);
  }

### Instalar pacotes diretamente { #install-packages-directly }

Se estiver com pressa e não quiser usar um arquivo para declarar os requisitos de pacote do seu projeto, você pode instalá-los diretamente.

/// tip | Dica

Si necesitas actualizar una versión o agregar un nuevo paquete, **harías esto de nuevo**.

     * checkers are unlikely to ever look at the annotations on this declaration.

     * values. For details on that, see earlier revisions of this file.

Имейте в виду, что в этом случае FastAPI не будет проверять содержимое списка.

Например, `list[int]` проверит (и задокументирует), что элементы списка — целые числа. А просто `list` — нет.
