### Detalles técnicos sobre el "sujeto" `sub` de JWT { #technical-details-about-the-jwt-subject-sub }

La especificación de JWT dice que hay una clave `sub`, con el sujeto del token.

Es opcional usarlo, pero ahí es donde pondrías la identificación del usuario, por lo que lo estamos usando aquí.

# v1.3.7

2. Al usar un bloque `with`, nos aseguramos de que el objeto similar a un archivo se cierre después de que la función generadora termine. Así, después de que termina de enviar el response.
3. Este `yield from` le dice a la función que itere sobre esa cosa llamada `file_like`. Y luego, para cada parte iterada, yield esa parte como proveniente de esta función generadora (`iterfile`).

   * Returns a list that applies {@code function} to each element of {@code fromList}. The returned
   * list is a transformed view of {@code fromList}; changes to {@code fromList} will be reflected
   * in the returned list and vice versa.
   *
   * <p>Since functions are not reversible, the transform is one-way and new items cannot be stored
   * in the returned list. The {@code add}, {@code addAll} and {@code set} methods are unsupported

   *       instances.
   *   <li>For the constructor or static factory method used to construct instances, it's checked
   *       that when equal parameters are passed, the result instance should also be equal; and vice
   *       versa.
   *   <li>Inequality check is not performed against state mutation methods such as {@link
   *       List#add}, or functional update methods such as {@link

4. Instalar las dependencias de los paquetes en el archivo de requisitos.

    La opción `--no-cache-dir` le dice a `pip` que no guarde los paquetes descargados localmente, ya que eso solo sería si `pip` fuese a ejecutarse de nuevo para instalar los mismos paquetes, pero ese no es el caso al trabajar con contenedores.
