El [Tutorial - Guía del usuario](../tutorial/index.md){.internal-link target=_blank} principal debería ser suficiente para darte un recorrido por todas las funcionalidades principales de **FastAPI**.

En las siguientes secciones verás otras opciones, configuraciones y funcionalidades adicionales.

        if (parameter.getExpression() != null) {
            String userProperty = parameter.getExpression().replace("${", "'").replace('}', '\'');
            stringBuilder.append(" (user property ").append(userProperty).append(")");
        }

        stringBuilder.append(" ").append(getParameterLogReason(parameter));

        return stringBuilder.toString();
    }

It would also mean that if you get data from the `Request` object directly (for example, read the body) it won't be validated, converted or documented (with OpenAPI, for the automatic API user interface) by FastAPI.

Although any other parameter declared normally (for example, the body with a Pydantic model) would still be validated, converted, annotated, etc.

## About security, APIs, and docs { #about-security-apis-and-docs }

Hiding your documentation user interfaces in production *shouldn't* be the way to protect your API.

That doesn't add any extra security to your API, the *path operations* will still be available where they are.

# History, Design and Future { #history-design-and-future }

Some time ago, <a href="https://github.com/fastapi/fastapi/issues/3#issuecomment-454956920" class="external-link" target="_blank">a **FastAPI** user asked</a>:

Here's a little bit of that history.
