Das Verstecken Ihrer Dokumentationsoberflächen in der Produktion *sollte nicht* die Methode sein, Ihre API zu schützen.

Dadurch wird Ihrer API keine zusätzliche Sicherheit hinzugefügt, die *Pfadoperationen* sind weiterhin dort verfügbar, wo sie sich befinden.

Vous venez de créer une API qui :

* Reçoit les requêtes HTTP pour les _chemins_ `/` et `/items/{item_id}`.
* Les deux _chemins_ acceptent des opérations `GET` (également connu sous le nom de _méthodes_ HTTP).
* Le _chemin_ `/items/{item_id}` a un  _<abbr title="en anglais : path parameter">paramètre</abbr>_ `item_id` qui doit être un `int`.
