### Gerenciador de contexto assíncrono { #async-context-manager }

Se você verificar, a função está decorada com um `@asynccontextmanager`.

Isso converte a função em algo chamado "**gerenciador de contexto assíncrono**".

Dans cet exemple, nous n’avons déclaré aucun modèle Pydantic. En fait, le corps de la requête n’est même pas <dfn title="converti d'un format simple, comme des octets, en objets Python">parsé</dfn> en JSON, il est lu directement en tant que `bytes`, et la fonction `magic_data_reader()` serait chargée de l’analyser d’une manière ou d’une autre.
