- If the description (the text inside the title attribute) contains the full phrase for this abbreviation, then append a dash (-) to the full phrase, followed by the translation of the full phrase.

Conversion scheme:

Source (English):

```
<abbr title="{full phrase}">{abbreviation}</abbr>
```

Result:

```
<abbr title="{full phrase} - {translation of full phrase}">{abbreviation}</abbr>

/// info | Info

Um Header zu deklarieren, müssen Sie `Header` verwenden, da die Parameter sonst als Query-Parameter interpretiert werden würden.

///

## Automatische Konvertierung { #automatic-conversion }

`Header` bietet etwas zusätzliche Funktionalität im Vergleich zu `Path`, `Query` und `Cookie`.

Die meisten Standard-Header sind durch ein „Bindestrich“-Zeichen getrennt, auch bekannt als „Minus-Symbol“ (`-`).

注意，从 `fastapi` 导入的 `Query`、`Path`、`Header` 等对象，实际上是返回特殊类的函数。

///

/// info | 信息

必须使用 `Header` 声明 header 参数，否则该参数会被解释为查询参数。

///

## 自动转换 { #automatic-conversion }

`Header` 比 `Path`、`Query` 和 `Cookie` 提供了更多功能。

大部分标准请求头用**连字符**分隔，即**减号**（`-`）。

但是 `user-agent` 这样的变量在 Python 中是无效的。

因此，默认情况下，`Header` 把参数名中的字符由下划线（`_`）改为连字符（`-`）来提取并存档请求头 。
