utilizando o mesmo[Codificador Compatível com JSON](../tutorial/encoder.md){.internal-link target=_blank} explicado no tutorial. Isso permite que você retorne **objetos abstratos**, como modelos do banco de dados, por exemplo.

Mas se você tem certeza que o conteúdo que você está retornando é **serializável com JSON**, você pode passá-lo diretamente para a classe de resposta e evitar o trabalho extra que o FastAPI teria ao passar o conteúdo pelo `jsonable_encoder` antes de passar para a classe...

	// JWT token for x-amz-security-token is signed with admin
	// secret key, temporary credentials become invalid if
	// server admin credentials change. This is done to ensure
	// that clients cannot decode the token using the temp
	// secret keys and generate an entirely new claim by essentially
	// hijacking the policies. We need to make sure that this is
	// based on admin credential such that token cannot be decoded

* `fixedquery`: tiene el valor exacto `fixedquery`.
* `$`: termina allí, no tiene más caracteres después de `fixedquery`.

Si te sientes perdido con todas estas ideas de **"expresión regular"**, no te preocupes. Son un tema difícil para muchas personas. Aún puedes hacer muchas cosas sin necesitar expresiones regulares todavía.

Pero cuando las necesites y vayas a aprenderlas, ya sabes que puedes usarlas directamente en **FastAPI**.
