### `HTTPException` Hata Handler’ını Override Etmek { #override-the-httpexception-error-handler }

Benzer şekilde `HTTPException` handler’ını da override edebilirsiniz.

Örneğin bu hatalar için JSON yerine plain text response döndürmek isteyebilirsiniz:

{* ../../docs_src/handling_errors/tutorial004_py310.py hl[3:4,9:11,25] *}

/// note | Teknik Detaylar

### 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:

{* ../../docs_src/handling_errors/tutorial004_py310.py hl[3:4,9:11,25] *}

/// note | Detalhes Técnicos

Nimmt Text oder Bytes entgegen und gibt eine HTML-Response zurück, wie Sie oben gelesen haben.

### `PlainTextResponse` { #plaintextresponse }

Nimmt Text oder Bytes entgegen und gibt eine Plain-Text-Response zurück.

{* ../../docs_src/custom_response/tutorial005_py310.py hl[2,7,9] *}

### `JSONResponse` { #jsonresponse }

Nimmt einige Daten entgegen und gibt eine `application/json`-codierte Response zurück.

   * backing sets do. Contains methods to copy the data into a new set which will then remain
   * stable. There is usually no reason to retain a reference of type {@code SetView}; typically,
   * you either use it as a plain {@link Set}, or immediately invoke {@link #immutableCopy} or
   * {@link #copyInto} and forget the {@code SetView} itself.

other file compiled by the C++ compiler, the go tool will use the
-extld option to set the host linker to the C++ compiler.

These defaults mean that Go-aware build systems can ignore the linking
changes and keep running plain 'cmd/link' and get reasonable results, but
they can also control the linking details if desired.
