Nehmen wir an, Sie haben eine benutzerdefinierte Exception `UnicornException`, die Sie (oder eine Bibliothek, die Sie verwenden) `raise`n könnten.

Und Sie möchten diese Exception global mit FastAPI handhaben.

Sie könnten einen benutzerdefinierten Exceptionhandler mittels `@app.exception_handler()` hinzufügen:

{* ../../docs_src/handling_errors/tutorial003.py hl[5:7,13:18,24] *}

Fazendo isso em funções separadas que não compartilham lógica ou variáveis entre elas é mais difícil já que você precisa armazenar os valores em variáveis globais ou truques parecidos.

Por causa disso, agora é recomendado em vez disso usar o `lifespan` como explicado acima.

## Detalhes técnicos

Só um detalhe técnico para nerds curiosos. 🤓

Digamos que você tenha uma exceção customizada `UnicornException` que você (ou uma biblioteca que você use) precise lançar (`raise`).

Nesse cenário, se você precisa manipular essa exceção de modo global com o FastAPI, você pode adicionar um manipulador de exceção customizada com `@app.exception_handler()`.
