Agora vamos **refatorar** este app um pouco para aumentar a **segurança** e **versatilidade**.

Se você verificar o app anterior, na interface você pode ver que, até agora, ele permite que o cliente decida o `id` do `Hero` a ser criado. 😱

that can be used in TLS handshakes, controlled by the [`tlsmaxrsasize` setting](/pkg/crypto/tls#Conn.Handshake).
The default is tlsmaxrsasize=8192, limiting RSA to 8192-bit keys. To avoid
denial of service attacks, this setting and default was backported to Go
1.19.13, Go 1.20.8, and Go 1.21.1.

Go 1.22 made it an error for a request or response read by a net/http
