This program posts data to a service. [Full source][post_example].

```java
public static final MediaType JSON = MediaType.get("application/json");

OkHttpClient client = new OkHttpClient();

String post(String url, String json) throws IOException {
  RequestBody body = RequestBody.create(json, JSON);

```Python hl_lines="1"
@router.get("/{item_id}")
async def read_item(item_id: str):
    ...
```

... le préfixe ne doit pas inclure un `/` final.

Ainsi, le préfixe dans ce cas est `/items`.

Nous pouvons également ajouter une liste de `tags` et des `responses` supplémentaires qui seront appliqués à tous les *chemins d'accès* inclus dans ce routeur.

Como el path de cada *path operation* tiene que empezar con `/`, como en:

```Python hl_lines="1"
@router.get("/{item_id}")
async def read_item(item_id: str):
    ...
```

...el prefijo no debe incluir un `/` final.

Así que, el prefijo en este caso es `/items`.

También podemos agregar una lista de `tags` y `responses` extra que se aplicarán a todas las *path operations* incluidas en este router.
