#### « Schéma » d’API { #api-schema }

Ici, [OpenAPI](https://github.com/OAI/OpenAPI-Specification) est une spécification qui dicte comment définir le schéma de votre API.

Cette définition de schéma inclut les chemins de votre API, les paramètres possibles qu’ils prennent, etc.

#### « Schéma » de données { #data-schema }

A "schema" is a definition or description of something. Not the code that implements it, but just an abstract description.

#### API "schema" { #api-schema }

In this case, [OpenAPI](https://github.com/OAI/OpenAPI-Specification) is a specification that dictates how to define a schema of your API.

This schema definition includes your API paths, the possible parameters they take, etc.

#### Data "schema" { #data-schema }

As this is a WebSocket it doesn't really make sense to raise an `HTTPException`, instead we raise a `WebSocketException`.

You can use a closing code from the [valid codes defined in the specification](https://tools.ietf.org/html/rfc6455#section-7.4.1).

この例では、`str` は次のとおりです:

Comme il s'agit d'un WebSocket, il n'est pas vraiment logique de lever une `HTTPException`, nous levons plutôt une `WebSocketException`.

Vous pouvez utiliser un code de fermeture parmi les [codes valides définis dans la spécification](https://tools.ietf.org/html/rfc6455#section-7.4.1).
