### Wstrzykiwanie Zależności

FastAPI zawiera niezwykle łatwy w użyciu, ale niezwykle potężny system <abbr title='Po angielsku: Dependency Injection. Znane również jako "components", "resources", "services", "providers"'><strong>Wstrzykiwania Zależności</strong></abbr>.

* Nawet zależności mogą mieć zależności, tworząc hierarchię lub **"graf" zależności**.
* Wszystko jest **obsługiwane automatycznie** przez framework.

### Dependency Injection { #dependency-injection }

FastAPI includes an extremely easy to use, but extremely powerful <abbr title='also known as "components", "resources", "services", "providers"'><strong>Dependency Injection</strong></abbr> system.

* Even dependencies can have dependencies, creating a hierarchy or **"graph" of dependencies**.
* All **automatically handled** by the framework.

                    throw new ServletException(e);
                }
            }
        };
    }

    /**
     * Helper method to initialize NetworkExplorer with mocked resources
     */
    private void initializeNetworkExplorer(boolean enableBasic, String realm) throws ServletException {
        networkExplorer = createMockedNetworkExplorer(enableBasic, realm);

### Dependency Injection

FastAPI bao gồm một hệ thống <abbr title='cũng biết đến như là "components", "resources", "services", "providers"'><strong>Dependency Injection</strong></abbr> vô cùng dễ sử dụng nhưng vô cùng mạnh mẽ.

```
/items/foo
```

/// info

Un "path" también es comúnmente llamado "endpoint" o "ruta".

///

Mientras construyes una API, el "path" es la forma principal de separar "concerns" y "resources".

#### Operación

"Operación" aquí se refiere a uno de los "métodos" HTTP.

Uno de:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...y los más exóticos:

* `OPTIONS`

### Injeção de dependência

FastAPI inclui um sistema de <abbr title='também conhecido como "components", "resources", "services", "providers"'><strong>injeção de dependência</strong></abbr> extremamente fácil de usar, mas extremamente poderoso.

* Mesmo dependências podem ter dependências, criando uma hierarquia ou **"grafo" de dependências**.

* Cách thiết lập **các ràng buộc cho validation** như `maximum_length` hoặc `regex`.
* Một hệ thống **<abbr title="cũng được biết đến như components, resources, providers, services, injectables">Dependency Injection</abbr> vô cùng mạnh mẽ và dễ dàng sử dụng.
* Bảo mật và xác thực, hỗ trợ **OAuth2**(với **JWT tokens**) và **HTTP Basic**.

 * your HTTP calls. This is because each client holds its own connection pool and thread pools.
 * Reusing connections and threads reduces latency and saves memory. Conversely, creating a client
 * for each request wastes resources on idle pools.
 *
 * Use `new OkHttpClient()` to create a shared instance with the default settings:
 *
 * ```java
 * // The singleton HTTP client.
 * public final OkHttpClient client = new OkHttpClient();
 * ```
