### 依存性の注入（Dependency Injection）

FastAPIには非常に使いやすく、非常に強力な<abbr title='also known as "components", "resources", "services", "providers"'><strong>依存性の注入</strong></abbr>システムを備えています。

* 依存関係でさえも依存関係を持つことができ、階層または **依存関係の"グラフ"** を作成することができます。

        // Default constructor
    }

    /** Header name for location redirects. */
    protected static final String LOCATION_HEADER = "Location";

    /** The crawler container for dependency injection. */
    @Resource
    protected CrawlerContainer crawlerContainer;

    /** Map of parser features to configure the DOM parser. */
    protected Map<String, String> featureMap = new HashMap<>();

* `maximum_length` və ya `regex` kimi **doğrulama məhdudiyyətlərinin** necə təyin ediləcəyi.
* Çox güclü və istifadəsi asan **<abbr title="components, resources, providers, services, injectables olaraq da bilinir">Dependency Injection</abbr>** sistemi.
* Təhlükəsizlik və autentifikasiya, **JWT tokenləri** ilə **OAuth2** dəstəyi və **HTTP Basic** autentifikasiyası.
