> NOTE: You can use the `-cscopes` parameter to restrict the requested scopes, for example to `"openid,policy_role_attribute"`, being `policy_role_attribute` a client_scope / client_mapper that maps a role attribute called policy to a `policy` claim returned by Keycloak.

Open your browser at <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>.

There you can set:

* The "Item ID", used in the path.
* The "Token" used as a query parameter.

/// tip

Notice that the query `token` will be handled by a dependency.

///

With that you can connect the WebSocket and then send and receive messages:

Caso ela não receba, ela retorna um erro HTTP 401 "Unauthorized" (*Não Autorizado*).

E retorna um cabeçalho `WWW-Authenticate` com o valor `Basic`, e um parâmetro opcional `realm`.

Isso sinaliza ao navegador para mostrar o prompt integrado para um usuário e senha.

Então, quando você digitar o usuário e senha, o navegador os envia automaticamente no cabeçalho.
