## Parámetros de Header con un Modelo Pydantic { #header-parameters-with-a-pydantic-model }

Declara los **parámetros de header** que necesitas en un **modelo Pydantic**, y luego declara el parámetro como `Header`:

package com.google.common.util.concurrent;

import com.google.common.annotations.GwtCompatible;
import com.google.common.annotations.J2ktIncompatible;

/**
 * Hidden superclass of {@link Futures} that provides us a place to declare special GWT versions of

 * java.util.concurrent.Executor) Futures.catching} family of methods. Those versions have slightly

import org.jspecify.annotations.Nullable;

/**
 * Hidden superclass of {@link FluentFuture} that provides us a place to declare special GWT
 * versions of the {@link FluentFuture#catching(Class, com.google.common.base.Function)
 * FluentFuture.catching} family of methods. Those versions have slightly different signatures.

## `Cookie` importieren { #import-cookie }

Importieren Sie zuerst `Cookie`:

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[3] *}

## `Cookie`-Parameter deklarieren { #declare-cookie-parameters }

Deklarieren Sie dann die Cookie-Parameter mit derselben Struktur wie bei `Path` und `Query`.

Sie können den Defaultwert sowie alle zusätzlichen Validierungen oder Annotierungsparameter definieren:

You can easily use the same Pydantic settings to configure your generated OpenAPI and the docs UIs.

For example:

{* ../../docs_src/conditional_openapi/tutorial001_py39.py hl[6,11] *}

Here we declare the setting `openapi_url` with the same default of `"/openapi.json"`.

And then we use it when creating the `FastAPI` app.

        MavenProject parentProject = createProject("groupId", "parent", "1.0");
        projects.add(parentProject);

        MavenProject declaringProject = createProject("groupId", "declarer", "1.0");
        declaringProject.setParent(parentProject);
        declaringProject.getModel().setParent(createParent(parentProject));
        projects.add(declaringProject);

## Импорт `Cookie` { #import-cookie }

Сначала импортируйте `Cookie`:

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[3] *}

## Объявление параметров `Cookie` { #declare-cookie-parameters }

Затем объявляйте параметры cookie, используя ту же структуру, что и с `Path` и `Query`.

Вы можете задать значение по умолчанию, а также все дополнительные параметры валидации или аннотации:

import com.google.common.base.Function;
import java.util.concurrent.Executor;
import org.jspecify.annotations.Nullable;

/**
 * Hidden superclass of {@link FluentFuture} that provides us a place to declare special GWT
 * versions of the {@link FluentFuture#catching(Class, com.google.common.base.Function)
 * FluentFuture.catching} family of methods. Those versions have slightly different signatures.

/// tip | Consejo

Esta misma técnica se aplica a `Query`, `Cookie`, y `Header`. 😎
