# CORS (Cross-Origin Resource Sharing) { #cors-cross-origin-resource-sharing }

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS ou "Cross-Origin Resource Sharing"</a> refere-se às situações em que um frontend rodando em um navegador possui um código JavaScript que se comunica com um backend, e o backend está em uma "origem" diferente do frontend.

## Origem { #origin }

# Códigos de Estado Adicionales { #additional-status-codes }

Por defecto, **FastAPI** devolverá los responses usando un `JSONResponse`, colocando el contenido que devuelves desde tu *path operation* dentro de ese `JSONResponse`.

Usará el código de estado por defecto o el que configures en tu *path operation*.

## Códigos de estado adicionales { #additional-status-codes_1 }

/// note

Some response codes (see the next section) indicate that the response does not have a body.

FastAPI knows this, and will produce OpenAPI docs that state there is no response body.

## About HTTP status codes { #about-http-status-codes }

/// note

If you already know what HTTP status codes are, skip to the next section.
