Nous pouvons utiliser **OAuth2** pour construire cela avec **FastAPI**.

Mais épargnons-vous le temps de lire toute la spécification complète juste pour trouver les petites informations dont vous avez besoin.

Utilisons les outils fournis par **FastAPI** pour gérer la sécurité.

* [`Parameter Object` (na especificação)](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object), usado no FastAPI por:
    * `Path()`
    * `Query()`
    * `Header()`
    * `Cookie()`
* [`Request Body Object`, no campo `content`, no `Media Type Object` (na especificação)](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#media-type-object), usado no FastAPI por:
    * `Body()`

* [`Parameter Object` (spesifikasyonda)](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object) — FastAPI’de şunlar tarafından kullanılıyordu:
    * `Path()`
    * `Query()`
    * `Header()`
    * `Cookie()`

                        // Ignore a missing signature for SMB < 3.0, as
                        // - the specification does not clearly require that (it does for SMB3+)
                        // - there seem to be server implementations (known: EMC Isilon) that do not sign the final
                        // response

// the function symbol 'name', logging an error for a malformed
// attribute clause if 'issueError' is true. The return value is a
// (boolean, ABI) pair indicating that the named symbol is either
// static or a particular ABI specification.
//
// The expected form of the attribute clause is:
//
// empty,           yielding (false, obj.ABI0)
// "<>",            yielding (true,  obj.ABI0)
// "<ABI0>"         yielding (false, obj.ABI0)

### A expressão do path do callback { #the-callback-path-expression }

* [`Parameter Object` (в спецификации)](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object), которое использовалось в FastAPI:
    * `Path()`
    * `Query()`
    * `Header()`
    * `Cookie()`
* [`Request Body Object`, в поле `content`, в `Media Type Object` (в спецификации)](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#media-type-object), которое использовалось в FastAPI:

          SSLContext.getInstance("TLS")

    val isAvailable: Boolean

 * equals</i>. That is, {@code a.compareTo(b)} or {@code comparator.compare(a, b)} should equal zero
 * <i>if and only if</i> {@code a.equals(b)}. If this advice is not followed, the resulting
 * collection will not correctly obey its specification.

### [Swagger](https://swagger.io/) / [OpenAPI](https://github.com/OAI/OpenAPI-Specification/) { #swagger-openapi }

我想從 Django REST Framework 得到的主要功能是自動 API 文件。

後來我發現有一個使用 JSON（或 YAML，JSON 的延伸）來描述 API 的標準，叫做 Swagger。

而且已有對 Swagger API 的網頁使用者介面。因此，只要能為 API 產生 Swagger 文件，就可以自動使用這個網頁介面。
