Vamos ver como isso funciona e como alterar se for necessário.

## Modelos Pydantic para Entrada e Saída { #pydantic-models-for-input-and-output }

Digamos que você tenha um modelo Pydantic com valores padrão, como este:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:7] hl[7] *}

### Modelo para Entrada { #model-for-input }

Se você usar esse modelo como entrada, como aqui:

* [PostgreSQL](https://hub.docker.com/_/postgres)
* [MySQL](https://hub.docker.com/_/mysql)
* [MongoDB](https://hub.docker.com/_/mongo)
* [Redis](https://hub.docker.com/_/redis), etc.

Durch Setzen von `--proxy-headers` kann FastAPI jetzt an den richtigen Ort umleiten. 😎
