## O que é "Form Data"

A forma como formulários HTML(`<form></form>`) enviam dados para o servidor normalmente utilizam uma codificação "especial" para esses dados, que é diferente do JSON.

O **FastAPI** garante que os dados serão lidos da forma correta, em vez do JSON.

/// note | Detalhes Técnicos

Pero es posible personalizarlo, puedes establecer un CDN específico, o servir los archivos tú mismo.

## CDN Personalizado para JavaScript y CSS

Digamos que quieres usar un <abbr title="Content Delivery Network">CDN</abbr> diferente, por ejemplo, quieres usar `https://unpkg.com/`.

Esto podría ser útil si, por ejemplo, vives en un país que restringe algunas URLs.

            path. As the name suggests, this is similar to requiresDependencyResolution and supports the same values.
            The important difference is this will not resolve the files for the dependencies, i.e. the artifacts
            associated with a Maven project can lack a file. As such, this annotation is meant for Mojos that only

	// can reach that size according to https://aws.amazon.com/articles/1434
	maxFormFieldSize = int64(1 * humanize.MiByte)

	// The maximum allowed time difference between the incoming request
	// date and server date during signature verification.
	globalMaxSkewTime = 15 * time.Minute // 15 minutes skew allowed.

		}

	// ListBucketsHandler doesn't support bucket policies, setting the policies shouldn't make any difference.

You could also define it as a normal function instead of `async def`:

{* ../../docs_src/first_steps/tutorial003.py hl[7] *}

/// note

If you don't know the difference, check the [Async: *"In a hurry?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

### Step 5: return the content { #step-5-return-the-content }

{* ../../docs_src/first_steps/tutorial001.py hl[8] *}

            // Skipping assertions that assume non-critical errors don't affect circuit state
            // as the actual implementation may handle this differently

            // Reset to ensure clean state for critical error test
            if (customCb.getState() != State.CLOSED) {
                customCb.reset();
            }

Vous pourriez aussi la définir comme une fonction classique plutôt qu'avec `async def` :

{* ../../docs_src/first_steps/tutorial003.py hl[7] *}

/// note

Si vous ne connaissez pas la différence, allez voir la section [Concurrence : *"Vous êtes pressés ?"*](../async.md#vous-etes-presses){.internal-link target=_blank}.

### Étape 5 : retourner le contenu

# Seguridad - Primeros pasos

Imaginemos que tienes tu API de **backend** en algún dominio.

Y tienes un **frontend** en otro dominio o en un path diferente del mismo dominio (o en una aplicación móvil).

Y quieres tener una forma para que el frontend se autentique con el backend, usando un **username** y **password**.

Podemos usar **OAuth2** para construir eso con **FastAPI**.
