So, you can use `user_agent` as you normally would in Python code, instead of needing to capitalize the first letters as `User_Agent` or something similar.

If for some reason you need to disable automatic conversion of underscores to hyphens, set the parameter `convert_underscores` of `Header` to `False`:

{* ../../docs_src/header_params/tutorial002_an_py310.py hl[10] *}

/// warning

Esto podría ser útil si, por ejemplo, vives en un país que restringe algunas URLs.

### Desactiva la documentación automática { #disable-the-automatic-docs }

El primer paso es desactivar la documentación automática, ya que por defecto, esos usan el CDN por defecto.

Para desactivarlos, establece sus URLs en `None` cuando crees tu aplicación de `FastAPI`:

Isso pode ser útil se, por exemplo, você mora em um país que restringe algumas URLs.

### Desativar a documentação automática { #disable-the-automatic-docs }

O primeiro passo é desativar a documentação automática, pois por padrão, ela usa o CDN padrão.

Para desativá-los, defina suas URLs como `None` ao criar sua aplicação FastAPI:

#
# SCOPE OPTIONS:
#   session - Cache for entire Maven session (all modules in multi-module build)
#   request - Cache only for current request + its child requests
#   none    - Disable caching entirely
#
# REFERENCE OPTIONS:
#   hard - Strong reference (stays in memory, faster access)
#   soft - Weak reference (can be garbage collected under memory pressure)
#
# CONFIGURATION BREAKDOWN:

FastAPI konvertiert die Konfigurationen nach **JSON**, um diese mit JavaScript kompatibel zu machen, da die Swagger-Oberfläche das benötigt.

## Syntaxhervorhebung deaktivieren { #disable-syntax-highlighting }

Sie könnten beispielsweise die Syntaxhervorhebung in der Swagger-Oberfläche deaktivieren.

Ohne Änderung der Einstellungen ist die Syntaxhervorhebung standardmäßig aktiviert:
