Tudo isso funciona graças aos [gerenciadores de contexto](https://docs.python.org/3/library/contextlib.html) do Python.

O **FastAPI** utiliza eles internamente para alcançar isso.

在 Let's Encrypt 之前，這些 **HTTPS 憑證**是由受信任的第三方販售。

取得這些憑證的流程過去相當繁瑣，需要許多手續，且憑證相當昂貴。

之後出現了 **[Let's Encrypt](https://letsencrypt.org/)**。

Infelizmente, eu não posso simplesmente confiar em PRs que têm várias aprovações.

Já aconteceu várias vezes de haver PRs com 3, 5 ou mais aprovações, provavelmente porque a descrição é atraente, mas quando eu verifico os PRs, eles estão quebrados, têm um bug, ou não resolvem o problema que afirmam resolver. 😅

Por isso, é realmente importante que você leia e execute o código, e me avise nos comentários que você fez isso. 🤓
