The same way, you can override the `HTTPException` handler.

For example, you could want to return a plain text response instead of JSON for these errors:

```Python hl_lines="3-4  9-11  22"
{!../../../docs_src/handling_errors/tutorial004.py!}
```

!!! note "Technical Details"
    You could also use `from starlette.responses import PlainTextResponse`.

Genauso können Sie den `HTTPException`-Handler überschreiben.

Zum Beispiel könnten Sie eine Klartext-Response statt JSON für diese Fehler zurückgeben wollen:

```Python hl_lines="3-4  9-11  22"
{!../../../docs_src/handling_errors/tutorial004.py!}
```

!!! note "Technische Details"
    Sie können auch `from starlette.responses import PlainTextResponse` verwenden.

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

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

```Python hl_lines="3-4  9-11  22"
{!../../../docs_src/handling_errors/tutorial004.py!}
```

!!! note "Detalhes Técnicos"
    Você pode usar `from starlette.responses import PlainTextResponse`.

修复错误时，客户端或用户不能访问错误的内部信息，否则会造成安全隐患。

### 覆盖 `HTTPException` 错误处理器

同理，也可以覆盖 `HTTPException` 处理器。

例如，只为错误返回纯文本响应，而不是返回 JSON 格式的内容：

```Python hl_lines="3-4  9-11  22"
{!../../../docs_src/handling_errors/tutorial004.py!}

```

!!! note "技术细节"

    还可以使用 `from starlette.responses import PlainTextResponse`。

This includes many libraries to interact with cloud storage, video processing, and others.

```{ .python .annotate hl_lines="2  10-12  14" }
{!../../../docs_src/custom_response/tutorial008.py!}
```

1. This is the generator function. It's a "generator function" because it contains `yield` statements inside.

Das umfasst viele Bibliotheken zur Interaktion mit Cloud-Speicher, Videoverarbeitung und anderen.

```{ .python .annotate hl_lines="2  10-12  14" }
{!../../../docs_src/custom_response/tutorial008.py!}
```

1. Das ist die Generatorfunktion. Es handelt sich um eine „Generatorfunktion“, da sie `yield`-Anweisungen enthält.
