## HTTPX

Mesmo que a sua aplicação **FastAPI** utilize funções normais com `def` no lugar de `async def`, ela ainda é uma aplicação `async` por baixo dos panos.

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

But there are specific cases where it's useful to get the `Request` object.

            return null;
        }

        String s = stripBasedirToken(path);

        File file = new File(s);
        if (file.isAbsolute()) {
            // path was already absolute, just normalize file separator and we're done
            s = file.getPath();
        } else if (file.getPath().startsWith(File.separator)) {
            // drive-relative Windows path, don't align with project directory but with drive root

 *
 * <p>We can't use {@code PartiallyGwtIncompatible} because then the GWT compiler wouldn't recognize
 * it as a {@code GwtIncompatible} annotation. And for {@code Futures.catching}, we need the GWT
 * compiler to autostrip the normal server method in order to expose the special, inherited GWT
 * version.

# GraphQL { #graphql }

As **FastAPI** is based on the **ASGI** standard, it's very easy to integrate any **GraphQL** library also compatible with ASGI.

You can combine normal FastAPI *path operations* with GraphQL on the same application.

/// tip

**GraphQL** solves some very specific use cases.

It has **advantages** and **disadvantages** when compared to common **web APIs**.

En estos casos, podría tener sentido almacenar las tags en un `Enum`.

**FastAPI** soporta eso de la misma manera que con strings normales:

## Resumen y Descripción

Puedes añadir un `summary` y `description`:

		ACB_PWNOTREQ               = 0x00000004, /* 1 = User password not required */
		ACB_TEMPDUP                = 0x00000008, /* 1 = Temporary duplicate account */
		ACB_NORMAL                 = 0x00000010, /* 1 = Normal user account */
		ACB_MNS                    = 0x00000020, /* 1 = MNS logon user account */
		ACB_DOMTRUST               = 0x00000040, /* 1 = Interdomain trust account */

Form verileri normalde `application/x-www-form-urlencoded` medya tipiyle kodlanır.

Ancak form içerisinde dosyalar yer aldığında `multipart/form-data` olarak kodlanır. Bir sonraki bölümde dosyaların işlenmesi hakkında bilgi edineceksiniz.
