# Histoire, conception et avenir

Il y a quelque temps, <a href="https://github.com/fastapi/fastapi/issues/3#issuecomment-454956920" class="external-link" target="_blank">un utilisateur de **FastAPI** a demandé</a> :

> Quelle est l'histoire de ce projet ? Il semble être sorti de nulle part et est devenu génial en quelques semaines [...].

Voici un petit bout de cette histoire.

## Alternatives

from fastapi import FastAPI
from fastapi.responses import RedirectResponse

app = FastAPI()


@app.get("/fastapi", response_class=RedirectResponse)
async def redirect_fastapi():

/// note | Detalhes Técnicos

Você também pode usar `from starlette import status`.

**FastAPI** fornece o mesmo `starlette.status` como `fastapi.status` apenas como uma conveniência para você, o desenvolvedor. Mas vem diretamente da Starlette.

First, import `Path` from `fastapi`, and import `Annotated`:

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[1,3] *}

/// info

FastAPI added support for `Annotated` (and started recommending it) in version 0.95.0.

If you have an older version, you would get errors when trying to use `Annotated`.

```console
$ pip install python-multipart
```

///

## `Form` importieren { #import-form }

Importieren Sie `Form` von `fastapi`:

{* ../../docs_src/request_forms/tutorial001_an_py39.py hl[3] *}

## `Form`-Parameter definieren { #define-form-parameters }

Erstellen Sie Formular-Parameter, so wie Sie es auch mit `Body` und `Query` machen würden:

from fastapi.testclient import TestClient

from docs_src.using_request_directly.tutorial001_py39 import app

client = TestClient(app)


def test_path_operation():
    response = client.get("/items/foo")
    assert response.status_code == 200
    assert response.json() == {"client_host": "testclient", "item_id": "foo"}


def test_openapi():
    response = client.get("/openapi.json")
    assert response.status_code == 200

## Дополнительные возможности { #additional-features }

Основное [Учебник - Руководство пользователя](../tutorial/index.md){.internal-link target=_blank} должно быть достаточно, чтобы познакомить вас со всеми основными функциями **FastAPI**.

В следующих разделах вы увидите другие варианты, конфигурации и дополнительные возможности.
