Puedes definir los parámetros de Header de la misma manera que defines los parámetros de `Query`, `Path` y `Cookie`.

## Importar `Header` { #import-header }

Primero importa `Header`:

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

## Declarar parámetros de `Header` { #declare-header-parameters }

Luego declara los parámetros de header usando la misma estructura que con `Path`, `Query` y `Cookie`.

/// note | Detalles Técnicos

También podrías usar `from starlette.responses import Response` o `from starlette.responses import JSONResponse`.

**FastAPI** proporciona las mismas `starlette.responses` como `fastapi.responses` solo por conveniencia para ti, el desarrollador. Pero la mayoría de los responses disponibles provienen directamente de Starlette.

## Errores de dependencias y valores de retorno { #dependencies-errors-and-return-values }

Puedes usar las mismas *funciones* de dependencia que usas normalmente.

### Requisitos de dependencia { #dependency-requirements }

Pueden declarar requisitos de request (como headers) u otras sub-dependencias:

package tests

import (
	"context"
	"testing"

	"gorm.io/gorm"
	"gorm.io/gorm/clause"
	"gorm.io/gorm/schema"
)

// testDialector is a minimal Dialector implementation used only for unit tests in-memory.
type testDialector struct{}

func (d testDialector) Name() string                                   { return "test" }
func (d testDialector) Initialize(*gorm.DB) error                      { return nil }

            SuggestCreator.Options options = new SuggestCreator.Options();
            options.propertiesPath = tempPropFile.getAbsolutePath();

            // Setup minimal mock components
            setupMockComponents();

            Method processMethod = SuggestCreator.class.getDeclaredMethod("process", SuggestCreator.Options.class);
            processMethod.setAccessible(true);

      // If the value is "quoted", drop the quotes.
      if (value.startsWith("\"") && value.endsWith("\"") && value.length >= 2) {
        value = value.substring(1, value.length - 1)
      }

      // Minimal normalisation so Cookie.Builder doesn't crash on values like "abc123 ".
      value = value.trim()

      result.add(
        Cookie
          .Builder()
          .name(name)
          .value(value)
