char[] uni = new char[slim - si];
        int ui, ch;

        for( ui = 0; si < slim && (ch = src[si++] & 0xFF) != 0; ui++ ) {
            if( ch < 0x80 ) {
                uni[ui] = (char)ch;
            } else if((ch & 0xE0) == 0xC0 ) {
                if((slim - si) < 2 ) {
                    break;
                }

    static_dir.mkdir(exist_ok=True)
    from docs_src.custom_docs_ui.tutorial001 import app

    with TestClient(app) as client:
        yield client
    static_dir.rmdir()


def test_swagger_ui_html(client: TestClient):
    response = client.get("/docs")
    assert response.status_code == 200, response.text
    assert (
        "https://unpkg.com/swagger-ui-dist@5.9.0/swagger-ui-bundle.js" in response.text
    )

Итак, хотя поле `example` не является частью JSON-схемы, оно является частью настраиваемой версии JSON-схемы в OpenAPI, и именно это поле будет использоваться в UI документации.

# OpenAPI `docs`

Werkzeuge zur Verwaltung der automatischen OpenAPI-UI-Dokumentation, einschließlich Swagger UI (standardmäßig unter `/docs`) und ReDoc (standardmäßig unter `/redoc`).

::: fastapi.openapi.docs.get_swagger_ui_html

::: fastapi.openapi.docs.get_redoc_html

::: fastapi.openapi.docs.get_swagger_ui_oauth2_redirect_html

    from docs_src.custom_docs_ui.tutorial002 import app

    with TestClient(app) as client:
        yield client
    static_dir.rmdir()


def test_swagger_ui_html(client: TestClient):
    response = client.get("/docs")
    assert response.status_code == 200, response.text
    assert "/static/swagger-ui-bundle.js" in response.text
    assert "/static/swagger-ui.css" in response.text

つまり、`example`はJSON Schemaの一部ではありませんが、OpenAPIの一部であり、それがdocs UIで使用されることになります。

Portanto, embora `example` não seja parte do JSON Schema, é parte da versão customizada do JSON Schema usada pelo OpenAPI, e é isso que vai ser usado dentro da UI de documentação.

 * For a particular application plugin there will be a declarative descriptor for that plugin type.
 *
 * - nexus - the plugin class - UI to contribute - what JS to hook into the UI - what resources to
 * load into the UI - having packed or unpacked plugins, and positioning resources if necessary -
 * maven can work out of the classloader, nexus plugins probably couldn't give the js and image
 * resources
