} catch (final Exception e) {
                                if (logger.isDebugEnabled()) {
                                    logger.debug("Failed to detect MIME type from file, using default: url={}, file={}, defaultMimeType={}",
                                            url, outputFile.getAbsolutePath(), defaultMimeType, e);
                                }

Por exemplo, com um ID de `42`, isso renderizará:

```html
<a href="/items/42">
```

## Templates e arquivos estáticos { #templates-and-static-files }

Você também pode usar `url_for()` dentro do template e usá-lo, por exemplo, com o `StaticFiles` que você montou com o `name="static"`.

```jinja hl_lines="4"
{!../../docs_src/templates/templates/item.html!}
```

### Файлы и async { #files-and-async }

В большинстве случаев «файлоподобные» объекты по умолчанию не совместимы с async и await.

Например, у них нет `await file.read()` или `async for chunk in file`.

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting development server 🚀

             Searching for package file structure from directories with
             <font color="#3465A4">__init__.py</font> files
             Importing from <font color="#75507B">/home/user/code/</font><font color="#AD7FA8">awesomeapp</font>

Mit beispielsweise der ID `42` würde dies Folgendes ergeben:

```html
<a href="/items/42">
```

## Templates und statische Dateien { #templates-and-static-files }

Sie können `url_for()` innerhalb des Templates auch beispielsweise mit den `StaticFiles` verwenden, die Sie mit `name="static"` gemountet haben.

```jinja hl_lines="4"
{!../../docs_src/templates/templates/item.html!}

### Dosyalar ve Async { #files-and-async }

Çoğu durumda dosya benzeri nesneler, varsayılan olarak async ve await ile uyumlu değildir.

Örneğin, `await file.read()` ya da `async for chunk in file` gibi şeyler yoktur.

Ve birçok durumda, diskte ya da ağda okundukları için, okumak engelleyici (event loop'u bloke edebilen) bir işlem olabilir.

```

...이는 *경로 처리 함수* `read_item(id=id)`가 처리할 동일한 URL로 링크를 생성합니다.

예를 들어, ID가 `42`일 경우, 이는 다음과 같이 렌더링됩니다:

```html
<a href="/items/42">
```

## 템플릿과 정적 파일 { #templates-and-static-files }

템플릿 내에서 `url_for()`를 사용할 수 있으며, 예를 들어 `name="static"`으로 마운트한 `StaticFiles`와 함께 사용할 수 있습니다.
