Because of that, it's now recommended to instead use the `lifespan` as explained above.

## Technical Details { #technical-details }

Just a technical detail for the curious nerds. 🤓

### Зависимости с `yield` и `StreamingResponse`, технические детали { #dependencies-with-yield-and-streamingresponse-technical-details }

До FastAPI 0.118.0, если вы использовали зависимость с `yield`, код после `yield` выполнялся после возврата из *функции-обработчика пути*, но прямо перед отправкой ответа.

3) Keep heading punctuation as in the source. In particular, keep occurrences of literal « - » (space-hyphen-space) as « - » (the existing French docs use a hyphen here).

### French instructions about technical terms

### OpenAPI Examples in the Docs UI { #openapi-examples-in-the-docs-ui }

With `openapi_examples` added to `Body()` the `/docs` would look like:

<img src="/img/tutorial/body-fields/image02.png">

## Technical Details { #technical-details }

/// tip

If you are already using **FastAPI** version **0.99.0 or above**, you can probably **skip** these details.

        defaultSettings.put("onelogin.saml2.organization.lang", "");
        defaultSettings.put("onelogin.saml2.contacts.technical.given_name", "Technical Guy");
        defaultSettings.put("onelogin.saml2.contacts.technical.email_address", "technical@example.com");
        defaultSettings.put("onelogin.saml2.contacts.support.given_name", "Support Guy");

And then another background task generated at the *path operation function* will write a message using the `email` path parameter.

## Technical Details { #technical-details }

The class `BackgroundTasks` comes directly from <a href="https://www.starlette.dev/background/" class="external-link" target="_blank">`starlette.background`</a>.

### Target language

Translate to Japanese (日本語).

Language code: ja.

### Grammar and tone

1) Use polite, instructional Japanese (です/ます調).
2) Keep the tone concise and technical (match existing Japanese FastAPI docs).

### Headings

1) Follow the existing Japanese style: short, descriptive headings (often noun phrases), e.g. 「チェック」.
2) Do not add a trailing period at the end of headings.

### Quotes

2) If a title is present, prefer these canonical titles:

- `/// note | 참고`
- `/// tip | 팁`
- `/// warning | 경고`
- `/// info | 정보`
- `/// danger | 위험`
- `/// note Technical Details | 기술 세부사항`
- `/// check | 확인`
Notes:

- `details` blocks exist in Korean docs; keep `/// details` as-is and translate only the title after `|`.

### Abhängigkeiten mit `yield` und `StreamingResponse`, Technische Details { #dependencies-with-yield-and-streamingresponse-technical-details }

Vor FastAPI 0.118.0 wurde bei Verwendung einer Abhängigkeit mit `yield` der Exit-Code nach der *Pfadoperation-Funktion* ausgeführt, aber unmittelbar bevor die Response gesendet wurde.

## Use `StaticFiles` { #use-staticfiles }

* Import `StaticFiles`.
* "Mount" a `StaticFiles()` instance in a specific path.

{* ../../docs_src/static_files/tutorial001_py39.py hl[2,6] *}

/// note | Technical Details

You could also use `from starlette.staticfiles import StaticFiles`.
