### Target language

Translate to Simplified Chinese (简体中文).

Language code: zh.

### Grammar and tone

1) Use clear, concise technical Chinese consistent with existing docs.
2) Address the reader naturally (commonly using “你/你的”).

### Headings

1) Follow existing Simplified Chinese heading style (short and descriptive).
2) Do not add trailing punctuation to headings.

Language code: ru.

---

Use a neutral tone (not overly formal or informal).

Use correct Russian grammar — appropriate cases, suffixes, and endings depending on context.

For the following technical terms, use these specific translations to ensure consistency and clarity across the documentation:

They are just a convenience, they hold the same number, but that way you can use the editor's autocomplete to find them:

/// note | Technical Details

You could also use `from starlette import status`.

**FastAPI** provides the same `starlette.status` as `fastapi.status` just as a convenience for you, the developer. But it comes directly from Starlette.

///

## Integrated middlewares { #integrated-middlewares }

**FastAPI** includes several middlewares for common use cases, we'll see next how to use them.

/// note | Technical Details

For the next examples, you could also use `from starlette.middleware.something import SomethingMiddleware`.

Если в запросе была строка запроса (query), она будет записана в лог фоновой задачей.

Затем другая фоновая задача, созданная в функции‑обработчике пути, запишет сообщение, используя path‑параметр `email`.

## Технические детали { #technical-details }

Класс `BackgroundTasks` приходит напрямую из <a href="https://www.starlette.dev/background/" class="external-link" target="_blank">`starlette.background`</a>.

So, you will receive a clean error, with an HTTP status code of `418` and a JSON content of:

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

/// note | Technical Details

You could also use `from starlette.requests import Request` and `from starlette.responses import JSONResponse`.

Antes de FastAPI 0.118.0, si usabas una dependencia con `yield`, ejecutaba el código de salida después de que la *path operation function* retornaba pero justo antes de enviar la response.
