/// info | 技術細節

`Security` 其實是 `Depends` 的子類別，僅多了一個我們稍後會看到的參數。

改用 `Security` 而不是 `Depends`，能讓 FastAPI 知道可以宣告安全性 scopes、在內部使用它們，並用 OpenAPI 文件化 API。

另外，當你從 `fastapi` 匯入 `Query`、`Path`、`Depends`、`Security` 等時，實際上它們是回傳特殊類別的函式。

## 使用 `SecurityScopes` { #use-securityscopes }

現在更新相依性 `get_current_user`。

上面的相依性就是使用它。

## Executando na inicialização { #running-on-startup }

Na maioria dos casos, quando você cria uma API web, você quer que ela esteja **sempre em execução**, ininterrupta, para que seus clientes possam sempre acessá-la. Isso é claro, a menos que você tenha um motivo específico para querer que ela seja executada somente em certas situações, mas na maioria das vezes você quer que ela esteja constantemente em execução e **disponível**.

        WebApiManager manager = new TestWebApiManager("/api/");

        TestHttpServletRequest request = new TestHttpServletRequest();
        request.setRequestURI("/api/search?query=test");
        assertTrue(manager.matches(request));

        request.setRequestURI("/api/data#anchor");
        assertTrue(manager.matches(request));
    }
