**FastAPI** will take the Pydantic model from there, generate the JSON Schema, and put it in the correct place.

The correct place is:

* In the key `content`, that has as value another JSON object (`dict`) that contains:
    * A key with the media type, e.g. `application/json`, that contains as value another JSON object, that contains:
        * A key `schema`, that has as the value the JSON Schema from the model, here's the correct place.

## Декілька параметрів тіла запиту

У попередньому прикладі *операція шляху* очікувала JSON з атрибутами `Item`, наприклад:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```
Але Ви також можете оголосити декілька параметрів тіла, наприклад `item` та `user`:

    response = client.get("/http-exception")
    assert response.status_code == 200
    assert response.json() == {"exception": "http-exception"}


def test_override_request_validation_exception():
    response = client.get("/request-validation/invalid")
    assert response.status_code == 200
    assert response.json() == {"exception": "request-validation"}


def test_override_server_error_exception_raises():

    response = client.get("/")
    assert response.status_code == 200, response.text
    assert response.json() == ["John Doe", "Jane Doe"]


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

	Enable     bool            `json:"enable"`
	Format     string          `json:"format"`
	URL        xnet.URL        `json:"url"`
	Index      string          `json:"index"`
	QueueDir   string          `json:"queueDir"`
	QueueLimit uint64          `json:"queueLimit"`
	Transport  *http.Transport `json:"-"`
	Username   string          `json:"username"`
	Password   string          `json:"password"`
}

    assert response.json() == {
        "name": "Baz",
        "description": None,
        "price": 50.2,
        "tax": 10.5,
        "tags": [],
    }


def test_put(client: TestClient):
    response = client.put(
        "/items/bar", json={"name": "Barz", "price": 3, "description": None}
    )
    assert response.json() == {
        "name": "Barz",
        "description": None,

			Value: "off",
		},
	}
)

// Args for general purpose policy engine configuration.
type Args struct {
	URL         *xnet.URL             `json:"url"`
	AuthToken   string                `json:"authToken"`
	Transport   http.RoundTripper     `json:"-"`
	CloseRespFn func(r io.ReadCloser) `json:"-"`
}

// Validate - validate opa configuration params.
func (a *Args) Validate() error {

По умолчанию **FastAPI** автоматически преобразует возвращаемое значение в JSON с помощью `jsonable_encoder`, как описано в [JSON кодировщик](../tutorial/encoder.md){.internal-link target=_blank}.

Затем "под капотом" эти данные, совместимые с JSON (например `dict`), помещаются в `JSONResponse`, который используется для отправки ответа клиенту.

    response = client.get("/cookie_examples/")
    assert response.status_code == 200, response.text


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": {
            "/examples/": {
                "post": {

// Config storage class configuration
type Config struct {
	CSPPolicy             string `json:"csp_policy"`
	HSTSSeconds           int    `json:"hsts_seconds"`
	HSTSIncludeSubdomains bool   `json:"hsts_include_subdomains"`
	HSTSPreload           bool   `json:"hsts_preload"`
	ReferrerPolicy        string `json:"referrer_policy"`
}

// Update Updates browser with new config
func (browseCfg *Config) Update(newCfg Config) {
