اکنون این مشخصه کمتر استفاده می‌شود و محبوبیت زیادی ندارد.

## استاندارد OpenAPI

استاندارد OpenAPI (قبلاً با نام Swagger شناخته می‌شد) یک open specification برای ساخت APIs (که در حال حاضر جزئی از بنیاد لینوکس میباشد) است.

فریم ورک **FastAPI** بر اساس **OpenAPI** است.

   * characters unescaped, they would be escaped by the consumer at parse time, anyway.</a>)
   * Additionally, the escaper escapes the slash character ("/"). While slashes are acceptable in
   * URL paths, they are considered by the specification to be separators between "path segments."
   * This implies that, if you wish for your path to contain slashes, you must escape each segment
   * separately and then join them.
   *

    private rpc() {
        // Utility class
    }

    /**
     * UUID (Universally Unique Identifier) structure for DCE/RPC.
     * Represents a 128-bit UUID as defined by DCE/RPC specification.
     */
    public static class uuid_t extends NdrObject {

        /**
         * Default constructor for uuid_t.
         */
        public uuid_t() {
            // Default constructor
        }

You can customize several metadata configurations in your **FastAPI** application.

## Metadata for API { #metadata-for-api }

You can set the following fields that are used in the OpenAPI specification and the automatic API docs UIs:

| Parameter | Type | Description |
|------------|------|-------------|
| `title` | `str` | The title of the API. |

Beachten Sie, dass der Pfad-Parameter dort als Ganzzahl deklariert ist.

## Nützliche Standards. Alternative Dokumentation

Und weil das generierte Schema vom <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md" class="external-link" target="_blank">OpenAPI</a>-Standard kommt, gibt es viele kompatible Tools.

And you want to have a way for the frontend to authenticate with the backend, using a **username** and **password**.

We can use **OAuth2** to build that with **FastAPI**.

But let's save you the time of reading the full long specification just to find those little pieces of information you need.

Let's use the tools provided by **FastAPI** to handle security.

## How it looks { #how-it-looks }

    * **Надёжный**: Получите готовый к работе код. С автоматической интерактивной документацией.
    * **Стандартизированный**: Основан на открытых стандартах API (<a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> и <a href="https://json-schema.org/" class="external-link" target="_blank">JSON Schema</a>) и полностью совместим с ними.

 *   generally: {@code 1.0.X2 < 1.0-X3 < 1.0.1} for any string {@code X}; but prefer {@code 1.0.0-X1}
 *   over {@code 1.0.0.X1}.</li>
 * </ul>

 * @see <a href="https://maven.apache.org/pom.html#version-order-specification">"Versioning" in the POM reference</a>

## Преимущества стандартизации, альтернативная документация

Поскольку сгенерированная схема соответствует стандарту <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md" class="external-link" target="_blank">OpenAPI</a>, её можно использовать со множеством совместимых инструментов.
