Normal header parametrelerinde olduğu gibi, parametre adlarında alt çizgi karakterleri olduğunda bunlar **otomatik olarak tireye dönüştürülür**.

Örneğin kodda `save_data` adlı bir header parametreniz varsa, beklenen HTTP header `save-data` olur ve dokümanlarda da bu şekilde görünür.

Herhangi bir sebeple bu otomatik dönüşümü kapatmanız gerekiyorsa, header parametreleri için kullandığınız Pydantic model'lerde de bunu devre dışı bırakabilirsiniz.

## 禁用下划线转换 { #disable-convert-underscores }

与常规的 header 参数相同，当参数名中包含下划线时，会**自动转换为连字符**。

例如，如果你的代码中有一个名为 `save_data` 的 header 参数，那么预期的 HTTP 头将是 `save-data`，并且在文档中也会以这种形式显示。

如果由于某些原因你需要禁用这种自动转换，你也可以在用于 header 参数的 Pydantic 模型中进行设置。
