### `UploadFile`

`UploadFile` 的属性如下：

* `filename`：上传文件名字符串（`str`），例如， `myimage.jpg`；
* `content_type`：内容类型（MIME 类型 / 媒体类型）字符串（`str`），例如，`image/jpeg`；

您将能够与您的**FastAPI**应用程序交互，从真实数据库中读取数据：

## 直接与数据库交互

如果您想独立于 FastAPI 直接浏览 SQLite 数据库（文件）以调试其内容、添加表、列、记录、修改数据等，您可以使用[SQLite 的 DB Browser](https://sqlitebrowser.org/)

它看起来像这样：

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

Oder, präziser, `user_dict` wird direkt verwendet, welche Werte es auch immer haben mag:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```

Verwenden Sie einfach jede Art von Modell, jede Art von Klasse, jede Art von Datenbank, die Sie für Ihre Anwendung benötigen. **FastAPI** deckt das alles mit seinem Dependency Injection System ab.

## Codegröße

Dieses Beispiel mag ausführlich erscheinen. Bedenken Sie, dass wir Sicherheit, Datenmodelle, Hilfsfunktionen und *Pfadoperationen* in derselben Datei vermischen.

Aber hier ist der entscheidende Punkt.
