#### `openapi.json` 확인

FastAPI는 자동으로 API의 설명과 함께 JSON (스키마)를 생성합니다.

가공되지 않은 OpenAPI 스키마가 어떻게 생겼는지 궁금하다면, 여기에서 직접 볼 수 있습니다: <a href="http://127.0.0.1:8000/openapi.json" class="external-link" target="_blank">http://127.0.0.1:8000/openapi.json</a>.

다음과 같이 시작하는 JSON을 확인할 수 있습니다:

```JSON
{
    "openapi": "3.0.2",
    "info": {
        "title": "FastAPI",

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


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/": {
                "get": {

///

### <a href="https://swagger.io/" class="external-link" target="_blank">Swagger</a> / <a href="https://github.com/OAI/OpenAPI-Specification/" class="external-link" target="_blank">OpenAPI</a> { #swagger-openapi }

Главной возможностью, которую хотелось взять из Django REST Framework, была автоматическая документация API.

But you can disable it by setting `syntaxHighlight` to `False`:

{* ../../docs_src/configure_swagger_ui/tutorial001_py39.py hl[3] *}

...and then Swagger UI won't show the syntax highlighting anymore:

        "paths": {
            "/items/{item_id}": {
                "get": {

    assert response.status_code == 200, response.text
    assert response.json() == {}


def test_openapi():
    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": {
            "/": {
                "get": {

):
    return {"p": p.p}


@pytest.mark.parametrize(
    "path",
    ["/optional-list-str", "/model-optional-list-str"],
)
def test_optional_list_str_schema(path: str):
    assert app.openapi()["paths"][path]["get"]["parameters"] == [
        {
            "required": False,
            "schema": {
                "anyOf": [
                    {"items": {"type": "string"}, "type": "array"},

<img src="/img/tutorial/extending-openapi/image02.png">

Pero puedes desactivarlo estableciendo `syntaxHighlight` en `False`:

{* ../../docs_src/configure_swagger_ui/tutorial001_py39.py hl[3] *}

...y entonces Swagger UI ya no mostrará el resaltado de sintaxis:
