## FastAPI의 기능

**FastAPI**는 다음과 같은 기능을 제공합니다:

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`.

{* ../../docs_src/bigger_applications/app_an_py39/routers/items.py hl[5:10,16,21] title["app/routers/items.py"] *}

Como o caminho de cada *operação de rota* deve começar com `/`, como em:

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

...o prefixo não deve incluir um `/` final.

Então, o prefixo neste caso é `/items`.

### Feature

- Add Timezone column in the output of kubectl get cronjob command ([#122231](https://github.com/kubernetes/kubernetes/pull/122231), [@ardaguclu](https://github.com/ardaguclu)) [SIG CLI]

ufw allow 9000:9010/tcp ``` ### firewall-cmd For hosts with firewall-cmd enabled (CentOS), you can use `firewall-cmd` command to allow traffic to specific ports. Use below commands to allow access to port 9000 ```sh firewall-cmd --get-active-zones ``` This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is `public`, use ```sh firewall-cmd --zone=public --add-port=9000/tcp --permanent ``` Note that `permanent` makes sure the rules...
