    Beachten Sie, dass die Verschlüsselung der Kommunikation auf der **TCP-Ebene** und nicht auf der HTTP-Ebene erfolgt.

### HTTPS-Request

Da Client und Server (sprich, der Browser und der TLS-Terminierungsproxy) nun über eine **verschlüsselte TCP-Verbindung** verfügen, können sie die **HTTP-Kommunikation** starten.

So brauchen Sie vorher nicht zu wissen, wie die Feld-/Attribut-Namen lauten (wie es bei Pydantic-Modellen der Fall wäre).

Das ist nützlich, wenn Sie Schlüssel empfangen, deren Namen Sie nicht bereits kennen.

Ein anderer nützlicher Anwendungsfall ist, wenn Sie Schlüssel eines anderen Typs haben wollen, z. B. `int`.

You can combine `dataclasses` with other type annotations in many different combinations to form complex data structures.

Check the in-code annotation tips above to see more specific details.

You can also combine `dataclasses` with other Pydantic models, inherit from them, include them in your own models, etc.

Help with translations is VERY MUCH appreciated! And it can't be done without the help from the community. 🌎 🚀

Here are the steps to help with translations.

#### Tips and guidelines

After this, the client and the server have an **encrypted TCP connection**, this is what TLS provides. And then they can use that connection to start the actual **HTTP communication**.

And that's what **HTTPS** is, it's just plain **HTTP** inside a **secure TLS connection** instead of a pure (unencrypted) TCP connection.

!!! tip

然后，通过使用证书，客户端和 TLS 终止代理 **决定如何加密** **TCP 通信** 的其余部分。 这就完成了 **TLS 握手** 部分。

此后，客户端和服务器就拥有了**加密的 TCP 连接**，这就是 TLS 提供的功能。 然后他们可以使用该连接来启动实际的 **HTTP 通信**。

这就是 **HTTPS**，它只是 **安全 TLS 连接** 内的普通 **HTTP**，而不是纯粹的（未加密的）TCP 连接。

!!! tip
     请注意，通信加密发生在 **TCP 层**，而不是 HTTP 层。

### HTTPS 请求

现在客户端和服务器（特别是浏览器和 TLS 终止代理）具有 **加密的 TCP 连接**，它们可以开始 **HTTP 通信**。

* Шифрование соединения происходит **на уровне протокола TCP**.
    * Протокол TCP находится на один уровень **ниже протокола HTTP**.
    * Поэтому **проверка сертификатов и шифрование** происходит **до HTTP**.
* **TCP не знает о "доменах"**, но знает об IP-адресах.
    * Информация о **запрашиваемом домене** извлекается из запроса **на уровне HTTP**.
