* 업로드 된 파일의 메타데이터를 얻을 수 있습니다.
* <a href="https://docs.python.org/3/glossary.html#term-file-like-object" class="external-link" target="_blank">file-like</a>  `async` 인터페이스를 갖고 있습니다.
* file-like object를 필요로하는 다른 라이브러리에 직접적으로 전달할 수 있는 파이썬 <a href="https://docs.python.org/3/library/tempfile.html#tempfile.SpooledTemporaryFile" class="external-link" target="_blank">`SpooledTemporaryFile`</a> 객체를 반환합니다.

## Escrevendo Templates

Então você pode escrever um template em `templates/item.html`, por exemplo:

```jinja hl_lines="7"
{!../../../docs_src/templates/templates/item.html!}
```

### Interpolação de Valores no Template

No código HTML que contém:

{% raw %}

```jinja
Item ID: {{ id }}
```

{% endraw %}

Jetzt können Sie die *Pfadoperationen* für die benutzerdefinierten Dokumentationen erstellen.

Sie können die internen Funktionen von FastAPI wiederverwenden, um die HTML-Seiten für die Dokumentation zu erstellen und ihnen die erforderlichen Argumente zu übergeben:

* `openapi_url`: die URL, unter welcher die HTML-Seite für die Dokumentation das OpenAPI-Schema für Ihre API abrufen kann. Sie können hier das Attribut `app.openapi_url` verwenden.
* `title`: der Titel Ihrer API.

따라서 다음 행

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

은 실행되지 않습니다.

## 디버거로 코드 실행

코드에서 직접 Uvicorn 서버를 실행하고 있기 때문에 디버거에서 직접 Python 프로그램(FastAPI 애플리케이션)을 호출할 수 있습니다.

예를 들어 Visual Studio Code에서 다음을 수행할 수 있습니다.

FastAPI is built on top of **Pydantic**, and I have been showing you how to use Pydantic models to declare requests and responses.

But FastAPI also supports using <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> the same way:

```Python hl_lines="1  7-12  19-20"
{!../../../docs_src/dataclasses/tutorial001.py!}
```

    * 存储在内存的文件超出最大上限时，FastAPI 会把文件存入磁盘；
* 这种方式更适于处理图像、视频、二进制文件等大型文件，好处是不会占用所有内存；
* 可获取上传文件的元数据；
* 自带 <a href="https://docs.python.org/zh-cn/3/glossary.html#term-file-like-object" class="external-link" target="_blank">file-like</a> `async` 接口；
* 暴露的 Python <a href="https://docs.python.org/zh-cn/3/library/tempfile.html#tempfile.SpooledTemporaryFile" class="external-link" target="_blank">`SpooledTemporaryFile`</a> 对象，可直接传递给其他预期「file-like」对象的库。
