**Requests** is a library to *interact* with APIs (as a client), while **FastAPI** is a library to *build* APIs (as a server).

They are, more or less, at opposite ends, complementing each other.

Requests has a very simple and intuitive design, it's very easy to use, with sensible defaults. But at the same time, it's very powerful and customizable.

That's why, as said in the official website:

Somente evitar a cópia de arquivos não melhora muito as coisas, mas porque ele usou o cache para esse passo, ele pode **usar o cache para o próximo passo**. Por exemplo, ele pode usar o cache para a instrução que instala as dependências com:

```Dockerfile
RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt
```

import org.apache.maven.api.annotations.Experimental;

Tenha em mente que o `RequestValidationError` contém as informações do nome do arquivo e da linha onde o erro de validação acontece, para que você possa mostrá-las nos seus logs com as informações relevantes, se quiser.

Podemos usar **OAuth2** para construir isso com o **FastAPI**.

Mas vamos poupar o seu tempo de ler toda a especificação extensa apenas para achar as pequenas informações de que você precisa.

Vamos usar as ferramentas fornecidas pelo **FastAPI** para lidar com segurança.
