이제 **FastAPI** 앱이 있는 `main.py` 파일에 몇 가지 다른 **경로 처리**가 추가된 경우를 생각해봅시다.

오류를 반환할 수 있는 `GET` 작업이 있습니다.

여러 다른 오류를 반환할 수 있는 `POST` 작업이 있습니다.

두 *경로 처리* 모두 `X-Token` 헤더를 요구합니다.

### 확장된 테스트 파일 { #extended-testing-file }

이제는 `test_main.py`를 확장된 테스트들로 수정할 수 있습니다:

Seguridad y autenticación integradas. Sin ningún compromiso con bases de datos o modelos de datos.

Todos los esquemas de seguridad definidos en OpenAPI, incluyendo:

* HTTP Básico.
* **OAuth2** (también con **tokens JWT**). Revisa el tutorial sobre [OAuth2 con JWT](tutorial/security/oauth2-jwt.md).
* API keys en:
    * Headers.
    * Parámetros de query.
    * Cookies, etc.

```

### Template Context Values { #template-context-values }

In the HTML that contains:

{% raw %}

```jinja
Item ID: {{ id }}
```

{% endraw %}

...it will show the `id` taken from the "context" `dict` you passed:

```Python
{"id": id}
```

For example, with an ID of `42`, this would render:

```html
Item ID: 42
```

    @Size(max = 1000)
    public String oicClientSecret;

    /** OpenID Connect authorization server URL. */
    @Size(max = 1000)
    public String oicAuthServerUrl;

    /** OpenID Connect token server URL. */
    @Size(max = 1000)
    public String oicTokenServerUrl;

    /** OpenID Connect redirect URL. */
    @Size(max = 1000)
    public String oicRedirectUrl;

    /** OpenID Connect scope. */

    }

    @Test
    public void test_getOicTokenServerUrl_default() {
        final String url = authenticator.getOicTokenServerUrl();
        assertEquals("https://accounts.google.com/o/oauth2/token", url);
    }

    @Test
    public void test_getOicClientId_default() {
        final String clientId = authenticator.getOicClientId();
        assertEquals("", clientId);
    }

    @Test

Тож помістимо їх у власний модуль `dependencies` (`app/dependencies.py`).

Тепер використаємо просту залежність для читання користувацького заголовка `X-Token`:

Ми використовуємо вигаданий заголовок, щоб спростити приклад.

- On finding at least one associated policy, MinIO generates temporary credentials for the user storing the list of groups in a cryptographically secure session token. The temporary access key, secret key and session token are returned to the user.
- The user can now use these credentials to make requests to the MinIO server.
