* key and value, which we pass to the superconstructor, even though the key and value type for
     * a given entry might not include null. The right fix for the header problems is probably to
     * define a separate MultimapLink interface with a separate "header" implementation, which
     * hopefully could avoid implementing Entry or ValueSetLink at all. (But note that that approach

**Spoiler-Alarm**: Das Tutorial - Benutzerhandbuch enthält:

* Deklaration von **Parametern** von anderen verschiedenen Stellen wie: **Header-Felder**, **Cookies**, **Formularfelder** und **Dateien**.
* Wie man **Validierungseinschränkungen** wie `maximum_length` oder `regex` setzt.

* `dependencies`: Sie alle benötigen die von uns erstellte `X-Token`-Abhängigkeit.

Anstatt also alles zu jeder *Pfadoperation* hinzuzufügen, können wir es dem `APIRouter` hinzufügen.

```Python hl_lines="5-10  16  21" title="app/routers/items.py"
{!../../docs_src/bigger_applications/app/routers/items.py!}
```

Da der Pfad jeder *Pfadoperation* mit `/` beginnen muss, wie in:

```Python hl_lines="1"
@router.get("/{item_id}")

    }

    /** Returns all of the cookies from a set of HTTP response headers. */

    fun parseAll(
      url: HttpUrl,
      headers: Headers,

      val cookieStrings = headers.values("Set-Cookie")
      var cookies: MutableList<Cookie>? = null

      for (i in 0 until cookieStrings.size) {

* To pass a JSON body, pass a Python object (e.g. a `dict`) to the parameter `json`.
* If you need to send *Form Data* instead of JSON, use the `data` parameter instead.
* To pass *headers*, use a `dict` in the `headers` parameter.
* For *cookies*, a `dict` in the `cookies` parameter.

Mas isso só permitirá certos tipos de comunicação, excluindo tudo que envolva credenciais: cookies, cabeçalhos de autorização como aqueles usados ​​com Bearer Tokens, etc.

Então, para que tudo funcione corretamente, é melhor especificar explicitamente as origens permitidas.
