# Fonctionnalités

## Fonctionnalités de FastAPI

**FastAPI** vous offre ceci:

### Basé sur des standards ouverts

So, the frontend (that runs in the browser) would try to reach `/openapi.json` and wouldn't be able to get the OpenAPI schema.

Because we have a proxy with a path prefix of `/api/v1` for our app, the frontend needs to fetch the OpenAPI schema at `/api/v1/openapi.json`.

## OpenAPI and API docs { #openapi-and-api-docs }

If you return additional status codes and responses directly, they won't be included in the OpenAPI schema (the API docs), because FastAPI doesn't have a way to know beforehand what you are going to return.

/// warning

Extra keys passed to `Field` will also be present in the resulting OpenAPI schema for your application.
As these keys may not necessarily be part of the OpenAPI specification, some OpenAPI tools, for example [the OpenAPI validator](https://validator.swagger.io/), may not work with your generated schema.

## OpenAPI y documentación de API

Si devuelves códigos de estado adicionales y responses directamente, no se incluirán en el esquema de OpenAPI (la documentación de la API), porque FastAPI no tiene una forma de saber de antemano qué vas a devolver.

## Beneficios basados en estándares, documentación alternativa

Y porque el esquema generado es del estándar <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md" class="external-link" target="_blank">OpenAPI</a>, hay muchas herramientas compatibles.

# ویژگی ها

## ویژگی های FastAPI

**FastAPI** موارد زیر را به شما ارائه میدهد:

### برپایه استاندارد های باز

**FastAPI** weiß, dass es diese Abhängigkeit verwenden kann, um ein „Sicherheitsschema“ im OpenAPI-Schema (und der automatischen API-Dokumentation) zu definieren.

Вскоре мы создадим и саму операцию пути.

/// info | Дополнительная информация

Если вы очень строгий "питонист", то вам может не понравиться стиль названия параметра `tokenUrl` вместо `token_url`.

* Ter padrões sensíveis, mas customizações poderosas.

O principal recurso que eu queria do Django REST Framework era a documentação automática da API.
