* Champs String (`str`), définition de longueur minimum ou maximale.
    * Nombres (`int`, `float`) avec valeur minimale and maximale, etc.

* Validation pour des types plus exotiques, tel que:
    * URL.
    * Email.
    * UUID.

Toutes les validations sont gérées par le bien établi et robuste **Pydantic**.

### Sécurité et authentification

<img src="/img/tutorial/generate-clients/image07.png">

As you see, the method names now have the tag and then the function name, now they don't include information from the URL path and the HTTP operation.

### Preprocess the OpenAPI Specification for the Client Generator

The generated code still has some **duplicated information**.

リクエストに情報を渡せるクライアントが必要で、その方法がわからない場合はいつでも、`httpx` での実現方法を検索 (Google) できます。

テストでも同じことを行います。

例えば:

* *パス* または *クエリ* パラメータを渡すには、それをURL自体に追加します。
* JSONボディを渡すには、Pythonオブジェクト (例: `dict`) を `json` パラメータに渡します。
* JSONの代わりに *フォームデータ* を送信する必要がある場合は、代わりに `data` パラメータを使用してください。
* *ヘッダー* を渡すには、`headers` パラメータに `dict` を渡します。
* *cookies* の場合、 `cookies` パラメータに `dict` です。

  // Since non-resource URLs are not namespaced, this field is only applicable for ClusterRoles referenced from a ClusterRoleBinding.
  // Rules can either apply to API resources (such as "pods" or "secrets") or non-resource URL paths (such as "/api"),  but not both.
  // +optional
  repeated string nonResourceURLs = 6;
}

// Role is a namespaced, logical grouping of PolicyRules that can be referenced as a unit by a RoleBinding.

   the way the hostname verifier was selected.
 * Fix: Locking bug in SpdyConnection.
 * Fix: Ignore null header values (for compatibility with HttpURLConnection).
 * Add URLStreamHandlerFactory support so that `URL.openConnection()` uses
   OkHttp.
 * Expose the transport ("http/1.1", "spdy/3", etc.) via magic request headers.
   Use `X-Android-Transports` to write the preferred transports and

Then you just do the same in your tests.

E.g.:

* To pass a *path* or *query* parameter, add it to the URL itself.
* To pass a JSON body, pass a Python object (e.g. a `dict`) to the parameter `json`.
* If you need to send *Form Data* instead of JSON, use the `data` parameter instead.
