deveria ler primeiro o **Tutorial - Guia de Usuário** (que você está lendo agora).

Ele foi projetado para que você possa construir uma aplicação completa com apenas o **Tutorial - Guia de Usuário**, e então estendê-la de diferentes formas, dependendo das suas necessidades, usando algumas ideias adicionais do **Guia Avançado de Usuário**....

participant handler as Exception handler
participant dep as Dep with yield
participant operation as Path Operation
participant tasks as Background tasks

    Note over client,tasks: Can raise exception for dependency, handled after response is sent
    Note over client,operation: Can raise HTTPException and can change the response
    client ->> dep: Start request
    Note over dep: Run code up to yield
    opt raise

Lá você pode definir:

* O "Item ID", usado na rota.
* O "Token" usado como um parâmetro de consulta.

/// tip | Dica

Perceba que a consulta `token` será manipulada por uma dependência.

Com isso você pode conectar o WebSocket e então enviar e receber mensagens:
