`example` と `examples`について...

JSON Schemaの最新バージョンでは<a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a>というフィールドを定義していますが、OpenAPIは`examples`を持たない古いバージョンのJSON Schemaをベースにしています。

Il effectuera également un tri automatique de touts vos imports.

Pour qu'il puisse les trier correctement, vous devez avoir FastAPI installé localement dans votre environnement, avec la commande dans la section ci-dessus en utilisant `--symlink` (ou `--pth-file` sous Windows).

### Formatage des imports

Il existe un autre script qui permet de formater touts les imports et de s'assurer que vous n'avez pas d'imports inutilisés :

    }

    /**
     * Sets the configuration to the configuration taken from the specified build plugin in the POM. First, the build
     * plugins will be searched for the specified plugin, if that fails, the plugin management section will be searched.
     *
     * @param model The POM to extract the plugin configuration from, may be {@code null}.

   * typically useful for {@code return} statements. That leaves the code with two options: Either
   * add the suppression to the whole method (which turns off checking for a large section of code),
   * or extract a variable, and put the suppression on that. However, a local variable typically
   * doesn't work: Because nullness analyses typically infer the nullness of local variables,

# Extending OpenAPI

There are some cases where you might need to modify the generated OpenAPI schema.

In this section you will see how.

## The normal process

The normal (default) process, is as follows.

A `FastAPI` application (instance) has an `.openapi()` method that is expected to return the OpenAPI schema.

  * Replicate a service definition and change the name of the new service appropriately.
  * Update the command section in each service.
  * Add a new MinIO server instance to the upstream directive in the Nginx configuration file.

The main tasks that you can do right now are:

* [Help others with questions in GitHub](#help-others-with-questions-in-github){.internal-link target=_blank} (see the section above).
* [Review Pull Requests](#review-pull-requests){.internal-link target=_blank} (see the section above).

Those two tasks are what **consume time the most**. That's the main work of maintaining FastAPI.
