/**
 * Represents a hierarchical trace of nested requests within a session, enabling correlation between
 * session events and their originating operations in the application code. The trace structure
 * supports the following key features:
 *
 * <ul>
 *   <li>Maintains parent-child relationships between requests to track operation nesting</li>

/// warning

You can declare multiple `Form` parameters in a *path operation*, but you can't also declare `Body` fields that you expect to receive as JSON, as the request will have the body encoded using `application/x-www-form-urlencoded` instead of `application/json`.

This is not a limitation of **FastAPI**, it's part of the HTTP protocol.

Lorsque vous installez FastAPI (par exemple avec `pip install "fastapi[standard]"`), il est fourni avec un programme en ligne de commande que vous pouvez exécuter dans le terminal.

Pour exécuter votre application FastAPI en développement, vous pouvez utiliser la commande `fastapi dev` :

<div class="termy">

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.

Puedes declarar múltiples parámetros `Form` en una *path operation*, pero no puedes también declarar campos `Body` que esperas recibir como JSON, ya que el request tendrá el body codificado usando `application/x-www-form-urlencoded` en lugar de `application/json`.

Esto no es una limitación de **FastAPI**, es parte del protocolo HTTP.
