### Sobrescreva o manipulador de erro `HTTPException` { #override-the-httpexception-error-handler }

Do mesmo modo, você pode sobrescrever o `HTTPException`.

Por exemplo, você pode querer retornar uma *response* em *plain text* ao invés de um JSON para os seguintes erros:

Esse desacoplamento de partes, e ser um "microframework" que pode ser estendido para cobrir exatamente o que é necessário era uma funcionalidade chave que eu queria manter.

Dada a simplicidade do Flask, ele parecia uma boa opção para construção de APIs. A próxima coisa a encontrar era um "Django REST Framework" para Flask.
