```Python hl_lines="9  17"

So wie wir Pydantic zum Deklarieren von Bodys verwenden, können wir es auch überall sonst verwenden:

//// tab | Python 3.10+

```Python hl_lines="5  12-16"
{!> ../../docs_src/security/tutorial002_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="5  12-16"
{!> ../../docs_src/security/tutorial002_an_py39.py!}
```

////

//// tab | Python 3.8+

First, let's create a Pydantic user model.

The same way we use Pydantic to declare bodies, we can use it anywhere else:

//// tab | Python 3.10+

```Python hl_lines="5  12-16"
{!> ../../docs_src/security/tutorial002_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="5  12-16"
{!> ../../docs_src/security/tutorial002_an_py39.py!}
```

////

//// tab | Python 3.8+

### `examples`를 포함한 `Body`

여기, `Body()`에 예상되는 예제 데이터 하나를 포함한 `examples`를 넘겼습니다:

//// tab | Python 3.10+

```Python hl_lines="22-29"
{!> ../../docs_src/schema_extra_example/tutorial003_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="22-29"
{!> ../../docs_src/schema_extra_example/tutorial003_an_py39.py!}
```

////

//// tab | Python 3.8+

## First dependency "dependable"

You could create a first dependency ("dependable") like:

//// tab | Python 3.10+

```Python hl_lines="8-9"
{!> ../../docs_src/dependencies/tutorial005_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="8-9"
{!> ../../docs_src/dependencies/tutorial005_an_py39.py!}
```

////

//// tab | Python 3.8+

First, import `OAuth2PasswordRequestForm`, and use it as a dependency with `Depends` in the *path operation* for `/token`:

//// tab | Python 3.10+

```Python hl_lines="4  78"
{!> ../../docs_src/security/tutorial003_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="4  78"
{!> ../../docs_src/security/tutorial003_an_py39.py!}
```

////

//// tab | Python 3.8+

Importieren Sie zunächst `OAuth2PasswordRequestForm` und verwenden Sie es als Abhängigkeit mit `Depends` in der *Pfadoperation* für `/token`:

//// tab | Python 3.10+

```Python hl_lines="4  78"
{!> ../../docs_src/security/tutorial003_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="4  78"
{!> ../../docs_src/security/tutorial003_an_py39.py!}
```

////

//// tab | Python 3.8+

@needs_py310
def test_verify_password():
    from docs_src.security.tutorial005_an_py310 import fake_users_db, verify_password

    assert verify_password("secret", fake_users_db["johndoe"]["hashed_password"])


@needs_py310
def test_get_password_hash():
    from docs_src.security.tutorial005_an_py310 import get_password_hash

    assert get_password_hash("secretalice")


@needs_py310

**FastAPI** сам займётся их управлением.

## Провайдер зависимости

Можно создать первую зависимость следующим образом:

//// tab | Python 3.10+

```Python hl_lines="8-9"
{!> ../../docs_src/dependencies/tutorial005_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="8-9"
{!> ../../docs_src/dependencies/tutorial005_an_py39.py!}
```

////

//// tab | Python 3.6+

## Primeira dependência "injetável"

Você pode criar uma primeira dependência (injetável) dessa forma:

//// tab | Python 3.10+

```Python hl_lines="8-9"
{!> ../../docs_src/dependencies/tutorial005_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="8-9"
{!> ../../docs_src/dependencies/tutorial005_an_py39.py!}
```

////

//// tab | Python 3.8+
