## Ringkasan

* Impor `FastAPI`.
* Buat sebuah instance `app`.
* Tulis  **dekorator operasi path** menggunakan dekorator seperti `@app.get("/")`.
* Definisikan **fungsi operasi path**; sebagai contoh, `def root(): ...`.

## Recapitulando

* Importe `FastAPI`.
* Crie uma instância do `app`.
* Coloque o **decorador que define a operação** (como `@app.get("/")`).
* Escreva uma **função para a operação da rota** (como `def root(): ...`) abaixo.

        if (locale != null) {
            final String lang = locale.getLanguage();
            if (ComponentUtil.getFessConfig().isOnlineHelpSupportedLang(lang)) {
                target = lang.toUpperCase(Locale.ROOT);
            }
        }
        return url.replaceFirst("\\{lang\\}", target == null ? "EN" : target);
    }

* 🚨 Vermeiden Sie `Optional[SomeType]`
* Stattdessen ✨ **verwenden Sie `Union[SomeType, None]`** ✨.

Beide sind äquivalent und im Hintergrund dasselbe, aber ich empfehle `Union` statt `Optional`, weil das Wort „**optional**“ impliziert, dass dieser Wert, zum Beispiel als Funktionsparameter, optional ist. Tatsächlich bedeutet es aber nur „Der Wert kann `None` sein“, selbst wenn der Wert nicht optional ist und benötigt wird.

		// Validate that user exists.

## Підіб'ємо підсумки

* Імпортуємо `FastAPI`.
* Створюємо екземпляр `app`.
* Пишемо **декоратор операції шляху** як `@app.get("/")`.
* Пишемо **функцію операції шляху**; наприклад, `def root(): ...`.

## More details about `SecurityScopes` { #more-details-about-securityscopes }

You can use `SecurityScopes` at any point, and in multiple places, it doesn't have to be at the "root" dependency.

It will always have the security scopes declared in the current `Security` dependencies and all the dependants for **that specific** *path operation* and **that specific** dependency tree.
