### Ajouter des types

Modifions une seule ligne de la version précédente.

Nous allons changer seulement cet extrait, les paramètres de la fonction, de :


```Python
    first_name, last_name
```

à :

```Python
    first_name: str, last_name: str
```

C'est tout.

import jakarta.annotation.Resource;

/**
 * The base action class for Fess web application.
 * This abstract class provides common functionality for all Fess web actions,
 * including user authentication, validation, message handling, and access context management.
 * It extends LastaFlute's TypicalAction and implements validation and HTML path interfaces.

   * symmetry. Moreover, we don't want to reconstruct a native type variable {@code <A>} using our
   * implementation unless some of its bounds have changed in resolution. This avoids creating
   * unequal TypeVariable implementation unnecessarily. When the bounds do change, however, it's
   * fine for the synthetic TypeVariable to be unequal to any native TypeVariable anyway.

* `internal`: Internal
    * Use this for changes that only affect how the repo is managed. For example upgrades to internal dependencies, changes in GitHub Actions or scripts, etc.

**FastAPI** doesn't enforce any specific meaning.

The information here is presented as a guideline, not a requirement.

For example, when using GraphQL you normally perform all the actions using only `POST` operations.

### Step 4: define the **path operation function** { #step-4-define-the-path-operation-function }

This is our "**path operation function**":

* **path**: is `/`.
