Vous pouvez déclarer plusieurs paramètres de chemin et paramètres de requête en même temps, **FastAPI** sait lequel est lequel.

Et vous n'avez pas besoin de les déclarer dans un ordre spécifique.

Ils seront détectés par leur nom :

{* ../../docs_src/query_params/tutorial004_py310.py hl[6,8] *}

## Paramètres de requête requis { #required-query-parameters }

O `.add_task()` recebe como argumentos:

* Uma função de tarefa a ser executada em segundo plano (`write_notification`).
* Qualquer sequência de argumentos que deve ser passada para a função de tarefa na ordem (`email`).
* Quaisquer argumentos nomeados que devem ser passados para a função de tarefa (`message="some notification"`).

## Injeção de dependências { #dependency-injection }

Você pode ter subdependências e "árvores" de subdependências de qualquer tamanho e forma, e qualquer uma ou todas elas podem utilizar `yield`.

O **FastAPI** garantirá que o "código de saída" em cada dependência com `yield` é executado na ordem correta.

Por exemplo, `dependency_c` pode depender de `dependency_b`, e `dependency_b` depender de `dependency_a`:

{* ../../docs_src/dependencies/tutorial008_an_py310.py hl[6,14,22] *}

            "text-align": "left",
            "font-size": $element.css("font-size")
          });

          if (typeof setting.boxCssInfo === "undefined") {
            $boxElement.css({
              border: "1px solid #cccccc",
              "box-shadow":
                "0 1px 1px 0px rgba(0, 0, 0, 0.1), 0 3px 2px 0px rgba(82, 168, 236, 0.2)",
              "background-color": "#fff"
            });
          } else {

Und normalerweise ist es ein komplexes und „schwieriges“ Thema.

In vielen Frameworks und Systemen erfordert allein die Handhabung von Sicherheit und Authentifizierung viel Aufwand und Code (in vielen Fällen kann er 50 % oder mehr des gesamten geschriebenen Codes ausmachen).
