Client Authentication
---------------------

The above scenario is representative of most TLS set ups: the client uses certificates to validate
the identity of a server. The converse is also possible. Here we create a server that authenticates
a client and a client that authenticates a server.

```java
// Create the root for client and server to trust. We could also use different roots for each!

      .addConverterFactory(moshiConverterFactory)
      .callFactory(callFactory)
      .build()

  private val sslLabsApi = retrofit.create(SslLabsApi::class.java)

  suspend fun clients(): List<Client> =
    sslLabsApi.clients().map { userAgent ->
      Client(
        userAgent = userAgent.name,
        version = userAgent.version,
        platform = userAgent.platform,
        enabled = userAgent.suiteNames.map { SuiteId(null, it) },

Você pode utilizar a configuração de modelo do Pydantic para `proibir` qualquer campo `extra`:

{* ../../docs_src/request_form_models/tutorial002_an_py39.py hl[12] *}

Caso um cliente tente enviar informações adicionais, ele receberá um retorno de **erro**.

Por exemplo, se o cliente tentar enviar os campos de formulário:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

// ## SSE-C
//
// SSE-C computes the key-encryption-key from the client-provided key, an
// initialization vector (IV) and the bucket/object path.
//
//  1. Encrypt:
//     Input: ClientKey, bucket, object, metadata, object_data
//     -              IV := Random({0,1}²⁵⁶)
//     -       ObjectKey := SHA256(ClientKey || Random({0,1}²⁵⁶))
//     -       KeyEncKey := HMAC-SHA256(ClientKey, IV || 'SSE-C' || 'DAREv2-HMAC-SHA256' || bucket || '/' || object)

Si un cliente intenta enviar algunas **cookies extra**, recibirán un response de **error**.

Pobres banners de cookies con todo su esfuerzo para obtener tu consentimiento para que la <abbr title="Esta es otra broma. No me prestes atención. Toma un café para tu cookie. ☕">API lo rechace</abbr>. 🍪

* **`300 - 399`** são para "Redirecionamento". As respostas com esses códigos de status podem ou não ter um corpo, exceto `304`, "Não modificado", que não deve ter um.
* **`400 - 499`** são para respostas de "Erro do cliente". Este é o segundo tipo que você provavelmente mais usaria.

Damit können Sie den WebSocket verbinden und dann Nachrichten senden und empfangen:

<img src="/img/tutorial/websockets/image05.png">

## Verbindungsabbrüche und mehrere Clients handhaben { #handling-disconnections-and-multiple-clients }

Wenn eine WebSocket-Verbindung geschlossen wird, löst `await websocket.receive_text()` eine `WebSocketDisconnect`-Exception aus, die Sie dann wie in folgendem Beispiel abfangen und behandeln können.

        if (opLambda != null) {
            opLambda.callback(builder);
        }
    }

    public void setClientIp_SpanTerm(String clientIp) {
        setClientIp_SpanTerm("clientIp", null);
    }

    public void setClientIp_SpanTerm(String clientIp, ConditionOptionCall<SpanTermQueryBuilder> opLambda) {
        SpanTermQueryBuilder builder = regSpanTermQ("clientIp", clientIp);
