#  The base directory of package for generated class.
    #  The class package is 'this property value + detail package value'.
    #  However, detail packages have default value so basically
    #  you only have to specify the property 'packageBase'.
    #  If this property is specified and detail package properties is not specified, 
    #  Then the packages of generated class are as follows:
    #

```JSON
{
  "detail": "Item not found"
}
```

!!! tip "Tipp"
    Wenn Sie eine `HTTPException` auslösen, können Sie dem Parameter `detail` jeden Wert übergeben, der nach JSON konvertiert werden kann, nicht nur `str`.

    Zum Beispiel ein `dict`, eine `list`, usw.

```JSON
{
  "detail": "Item not found"
}
```

!!! tip "Dica"
    Quando você lançar um `HTTPException`, você pode passar qualquer valor convertível em JSON como parâmetro de `detail`, e não apenas `str`.

    Você pode passar um `dict` ou um `list`, etc.

```JSON
{
  "detail": "Item not found"
}
```

!!! tip
    When raising an `HTTPException`, you can pass any value that can be converted to JSON as the parameter `detail`, not only `str`.

    You could pass a `dict`, a `list`, etc.

    They are handled automatically by **FastAPI** and converted to JSON.

For consistency, the same profiles are used across each chart, even if they do not impact a given chart.

Explicitly set values have highest priority, then profile settings, then chart defaults.

As an implementation detail of profiles, the default values for the chart are all nested under `defaults`.
When configuring the chart, you should not include this.

```JSON
{
  "username": "johndoe",
  "email": "******@****.***",
  "full_name": "John Doe",
  "disabled": false,
  "hashed_password": "fakehashedsecret"
}
```

Wenn Sie auf das Schlosssymbol klicken und sich abmelden und dann den gleichen Vorgang nochmal versuchen, erhalten Sie einen HTTP 401 Error:

```JSON
{
  "detail": "Not authenticated"
}
```

You will get an "Inactive user" error, like:

```JSON
{
  "detail": "Inactive user"
}
```

## Recap

You now have the tools to implement a complete security system based on `username` and `password` for your API.

Using these tools, you can make the security system compatible with any database and with any user or data model.

The only detail missing is that it is not actually "secure" yet.

但如果客户端请求 `http://example.com/items/bar`（`item_id` `「bar」` 不存在时），则会接收到 HTTP 状态码 - 404（「未找到」错误）及如下 JSON 响应结果：

```JSON
{
  "detail": "Item not found"
}

```

!!! tip "提示"

    触发 `HTTPException` 时，可以用参数 `detail` 传递任何能转换为 JSON 的值，不仅限于 `str`。

    还支持传递 `dict`、`list` 等数据结构。

    **FastAPI** 能自动处理这些数据，并将之转换为 JSON。


## 添加自定义响应头

```JSON
{
  "detail": "Item not found"
}
```

!!! tip "Подсказка"
    При вызове `HTTPException` в качестве параметра `detail` можно передавать любое значение, которое может быть преобразовано в JSON, а не только `str`.

    Вы можете передать `dict`, `list` и т.д.

```
