Form gövdelerini tanımlamak için `Form` sınıfını kullanmanız gerekir; çünkü bu olmadan parametreler sorgu parametreleri veya gövde (JSON) parametreleri olarak yorumlanır.

## "Form Alanları" Hakkında

HTML formlarının (`<form></form>`) verileri sunucuya gönderirken JSON'dan farklı özel bir kodlama kullanır.

**FastAPI** bu verilerin JSON yerine doğru şekilde okunmasını sağlayacaktır.

Термін "схема" також може відноситися до структури даних, наприклад, JSON.

У цьому випадку це означає - атрибути JSON і типи даних, які вони мають тощо.

#### OpenAPI і JSON Schema

OpenAPI описує схему для вашого API. І ця схема включає визначення (або "схеми") даних, що надсилаються та отримуються вашим API за допомогою **JSON Schema**, стандарту для схем даних JSON.

#### Розглянемо `openapi.json`

    assert response.status_code == 200, response.text
    assert response.json() == {"msg": "Create an account first"}


def test_openapi_schema():
    response = client.get("/openapi.json")
    assert response.status_code == 200, response.text
    assert response.json() == {
        "openapi": "3.1.0",
        "info": {"title": "FastAPI", "version": "0.1.0"},
        "paths": {
            "/items/": {

    assert response.status_code == 401, response.text
    assert response.json() == {"detail": "Not authenticated"}
    assert response.headers["WWW-Authenticate"] == "Bearer"


def test_openapi_schema():
    response = client.get("/openapi.json")
    assert response.status_code == 200, response.text
    assert response.json() == {
        "openapi": "3.1.0",
        "info": {"title": "FastAPI", "version": "0.1.0"},

    )
    assert response.status_code == 200
    assert response.json() == {
        "limit": 10,
        "offset": 5,
        "order_by": "updated_at",
        "tags": ["tag1", "tag2"],
    }


def test_query_param_model_defaults(client: TestClient):
    response = client.get("/items/")
    assert response.status_code == 200
    assert response.json() == {
        "limit": 100,
        "offset": 0,

Dans ce cas, cela signifierait les attributs JSON, ainsi que les types de ces attributs, etc.

#### OpenAPI et JSON Schema

**OpenAPI** définit un schéma d'API pour votre API. Il inclut des définitions (ou "schémas") de la donnée envoyée et reçue par votre API en utilisant **JSON Schema**, le standard des schémas de données JSON.

#### Allez voir `openapi.json`

    assert response.status_code == 200, response.text
    assert response.json() == [{"item_id": "Foo"}]
