## Acerca de JWT

JWT significa "JSON Web Tokens".

Es un estándar para codificar un objeto JSON en un string largo y denso sin espacios. Se ve así:

```

 * elements, including {@code null}, are permitted.
 *
 * <p>{@code contains(x)}, {@code add(x)} and {@code remove(x)}, are all (expected and amortized)
 * constant time operations. Expected in the hashtable sense (depends on the hash function doing a
 * good job of distributing the elements to the buckets to a distribution not far from uniform), and
 * amortized since some operations can trigger a hash table resize.
 *

* Generate <a href="https://json-schema.org" class="external-link" target="_blank">JSON Schema</a> definitions for your model, you can also use them anywhere else you like if it makes sense for your project.
* Those schemas will be part of the generated OpenAPI schema, and used by the automatic documentation <abbr title="User Interfaces">UIs</abbr>.

## Sobre o JWT

JWT significa "JSON Web Tokens".

É um padrão para codificar um objeto JSON em uma string longa e densa sem espaços. Ele se parece com isso:

```
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c
```

Qualquer código de status HTTP (erro) 401 "UNAUTHORIZED" também deve retornar um cabeçalho `WWW-Authenticate`.

No caso de tokens ao portador (nosso caso), o valor desse cabeçalho deve ser `Bearer`.

Na verdade, você pode pular esse cabeçalho extra e ainda funcionaria.

Mas é fornecido aqui para estar em conformidade com as especificações.

     * <h4>Context-sensitive interpretation</h4>
     * This path type makes sense only when a main module is added on the module path by another dependency.
     * In no main module is found, the patch dependency may be added on the class path or module path
