此命令将在 `./src/client` 中生成代码，并将在其内部使用 `axios`（前端HTTP库）。

### 尝试客户端代码

现在您可以导入并使用客户端代码，它可能看起来像这样，请注意，您可以为这些方法使用自动补全：

您还将自动补全要发送的数据：

    return {"id": "foo"}


client = TestClient(app)


def test_swagger_ui():

## Introduction

Returns a set of temporary security credentials for applications/clients who have been authenticated through client credential grants provided by identity provider. Example providers include KeyCloak, Okta etc.

 *
 * Mainly intended to verify behaviour of popular clients across Android versions, similar
 * to observing Firefox or Chrome browser behaviour.

La primera parte de la comunicación es solo para establecer la conexión entre el cliente y el servidor y decidir las claves criptográficas que usarán, etc.

Esta interacción entre el cliente y el servidor para establecer la conexión TLS se llama **handshake TLS**.

### TLS con Extensión SNI { #tls-with-sni-extension }

 * authentication is optional.
 *
 * To perform client authentication:
 *
 *  * The client's handshake certificates must have a [held certificate][HeldCertificate] (a
 *    certificate and its private key). The client must also have a (possibly-empty) chain of
 *    intermediate certificates to establish trust from a root certificate to the client's
