### *Pfadoperationen* mit `APIRouter` { #path-operations-with-apirouter }

Und dann verwenden Sie ihn, um Ihre *Pfadoperationen* zu deklarieren.

Verwenden Sie ihn auf die gleiche Weise wie die Klasse `FastAPI`:

En esos casos, puedes usar el parámetro del decorador de path operation `response_model` en lugar del tipo de retorno.

Puedes usar el parámetro `response_model` en cualquiera de las *path operations*:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* etc.

### Создание *эндпоинтов* с помощью `APIRouter` { #path-operations-with-apirouter }

В дальнейшем используйте `APIRouter` для объявления *эндпоинтов*, точно также, как вы используете класс `FastAPI`:

 * read-write locks. Conceptually, lock striping is the technique of dividing a lock into many
 * <i>stripes</i>, increasing the granularity of a single lock and allowing independent operations
 * to lock different stripes and proceed concurrently, instead of creating contention for a single
 * lock.
 *
 * <p>The guarantee provided by this class is that equal keys lead to the same lock (or semaphore),

With the release of Kubernetes 1.18, an alpha version of CSI Proxy for Windows is getting released. CSI proxy enables non-privileged (pre-approved) containers to perform privileged storage operations on Windows. CSI drivers can now be supported in Windows by leveraging CSI proxy.
SIG Storage made a lot of progress in the 1.18 release.
In particular, the following storage features are moving to GA in Kubernetes 1.18:

Verás el response JSON como:

```JSON
{"item_id": 5, "q": "somequery"}
```

Ya creaste una API que:

* Recibe requests HTTP en los _paths_ `/` y `/items/{item_id}`.
* Ambos _paths_ toman _operaciones_ `GET` (también conocidas como métodos HTTP).
* El _path_ `/items/{item_id}` tiene un _parámetro de path_ `item_id` que debe ser un `int`.
* El _path_ `/items/{item_id}` tiene un _parámetro de query_ `q` opcional que es un `str`.
