## Détails techniques

La classe `BackgroundTasks` provient directement de <a href="https://www.starlette.io/background/" class="external-link" target="_blank">`starlette.background`</a>.

Но в реальных проектах, при внедрении системы безопасности, вы получите больше пользы используя интегрированные [средства защиты (следующая глава)](../security/index.md){.internal-link target=_blank}.

## Исключения в dependencies и возвращаемые значения

Вы можете использовать те же *функции* зависимостей, что и обычно.

### Требования к зависимостям

For example, let's add <a href="https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo" class="external-link" target="_blank">ReDoc's OpenAPI extension to include a custom logo</a>.

### Normal **FastAPI**

First, write all your **FastAPI** application as normally:

import okhttp3.mockwebserver.RecordedRequest;
import okio.ByteString;

/**
 * Runs a MockWebServer on localhost and uses it as the backend to receive an OAuth session.
 *
 * <p>Clients should call {@link #start}, {@link #newAuthorizeUrl} and {@link #close} in that order.
 * Clients may request multiple sessions.
 */
public final class OAuthSessionFactory extends Dispatcher implements Closeable {

import com.google.caliper.Param;
import java.util.Random;
import java.util.zip.Adler32;
import java.util.zip.CRC32;
import java.util.zip.Checksum;

/**
 * Benchmarks for comparing {@link Checksum}s and {@link HashFunction}s that wrap {@link Checksum}s.
 *
 * <p>Parameters for the benchmark are:
 *
 * <ul>
 *   <li>size: The length of the byte array to hash.
 * </ul>
