Si no lo recibe, devuelve un error HTTP 401 "Unauthorized".

Y devuelve un header `WWW-Authenticate` con un valor de `Basic`, y un parámetro `realm` opcional.

Eso le dice al navegador que muestre el prompt integrado para un nombre de usuario y contraseña.

Luego, cuando escribes ese nombre de usuario y contraseña, el navegador los envía automáticamente en el header.

Vamos a llamarlas "**operaciones**" también.

#### Define un *path operation decorator* { #define-a-path-operation-decorator }

El `@app.get("/")` le dice a **FastAPI** que la función justo debajo se encarga de manejar requests que vayan a:

* el path `/`
* usando una <dfn title="un método HTTP GET"><code>get</code> operación</dfn>

/// info | Información sobre `@decorator`

Como parte de eso, necesitaba investigar, probar y usar muchas alternativas.

La historia de **FastAPI** es en gran parte la historia de sus predecesores.

Como se dice en la sección [Alternativas](alternatives.md):

**FastAPI** no existiría si no fuera por el trabajo previo de otros.

But for the generated client, we could **modify** the OpenAPI operation IDs right before generating the clients, just to make those method names nicer and **cleaner**.

We could download the OpenAPI JSON to a file `openapi.json` and then we could **remove that prefixed tag** with a script like this:
