## Prohibir Parámetros Query Extras { #forbid-extra-query-parameters }

En algunos casos de uso especiales (probablemente no muy comunes), podrías querer **restringir** los parámetros query que deseas recibir.

Puedes usar la configuración del modelo de Pydantic para `forbid` cualquier campo `extra`:

 * This class provides a convenient wrapper around a Map to store and retrieve
 * data store specific parameters with type-safe access methods.
 *
 * <p>The class uses a ParamMap internally which provides case format conversion
 * between camelCase and snake_case parameter names for flexible parameter access.
 * Parameters can be stored as any Object type and retrieved with type conversion
 * support for common types like String.</p>
 *

Now, there are some cases where you might want to have the **same schema for input and output**.

Probably the main use case for this is if you already have some autogenerated client code/SDKs and you don't want to update all the autogenerated client code/SDKs yet, you probably will want to do it at some point, but maybe not right now.

In that case, you can disable this feature in **FastAPI**, with the parameter `separate_input_output_schemas=False`.
