Lá você pode definir:

* O "Item ID", usado na rota.
* O "Token" usado como um parâmetro de consulta.

Perceba que a consulta `token` será manipulada por uma dependência.

## Renvoyer une `Response` personnalisée

L'exemple ci-dessus montre toutes les parties dont vous avez besoin, mais il n'est pas encore très utile, car vous auriez pu retourner l'`item` directement, et **FastAPI** l'aurait mis dans une `JSONResponse` pour vous, en le convertissant en `dict`, etc. Tout cela par défaut.

Maintenant, voyons comment vous pourriez utiliser cela pour retourner une réponse personnalisée.

// Package lex implements lexical analysis for the assembler.
package lex

import (
	"fmt"
	"log"
	"os"
	"strings"
	"text/scanner"

	"cmd/internal/src"
)

// A ScanToken represents an input item. It is a simple wrapping of rune, as
// returned by text/scanner.Scanner, plus a couple of extra values.
type ScanToken rune

const (
	// Asm defines some two-character lexemes. We make up

        assertArgumentNotNull("children", children);
        assertArgumentNotNull("buf", buf);

        final int length = children.getLength();
        for (int i = 0; i < length; ++i) {
            appendNode(children.item(i), buf);
        }
    }

    /**
     * {@link NamedNodeMap}の文字列表現を追加します。
     *
     * @param attrs
     *            属性。{@literal null}であってはいけません
     * @param buf

```Python hl_lines="8"

```

Nesse caso, a função de manipulação de evento `startup` irá inicializar os itens do "banco de dados" (só um `dict`) com alguns valores.

Você pode adicionar mais que uma função de manipulação de evento.

- Fixed a regression in 1.23 that incorrectly pruned data from array items of a custom resource that set `x-kubernetes-preserve-unknown-fields: true`. ([#107688](https://github.com/kubernetes/kubernetes/pull/107688), [@liggitt](https://github.com/liggitt))

## Returning a custom `Response`

The example above shows all the parts you need, but it's not very useful yet, as you could have just returned the `item` directly, and **FastAPI** would put it in a `JSONResponse` for you, converting it to a `dict`, etc. All that by default.

Now, let's see how you could use that to return a custom response.

	NotBefore    string `json:"not_before"`
	Type         string `json:"type"`
	TrustDomain  string `json:"trust_domain"`
}

// NewSecretItemBuilder returns a new builder to create a secret item
func NewSecretItemBuilder() SecretItemBuilder {
	return &secretItemBuilder{}
}

// SecretItemBuilder wraps the process of setting fields for the SecretItem

    checkNotNull(collection);
    Iterable<E> iterable = getDelegate();
    if (iterable instanceof Collection) {
      collection.addAll((Collection<E>) iterable);
    } else {
      for (E item : iterable) {
        collection.add(item);
      }
    }
    return collection;
  }

  /**
   * Returns a {@link String} containing all of the elements of this fluent iterable joined with
   * {@code joiner}.
   *

                    final NodeList nodeList = doc.getElementsByTagName("component");
                    for (int i = 0; i < nodeList.getLength(); i++) {
                        final Node node = nodeList.item(i);
                        final NamedNodeMap attributes = node.getAttributes();
                        if (attributes != null) {
                            final Node classAttr = attributes.getNamedItem("class");
