o

```
http://127.0.0.1:8000/items/foo?short=yes
```

o cualquier otra variación (mayúsculas, primera letra en mayúscula, etc.), tu función verá el parámetro `short` con un valor `bool` de `True`. De lo contrario, será `False`.

## Múltiples parámetros de path y de query

Se você abrir no seu navegador a URL:

```
http://127.0.0.1:8000/items/foo-item
```

... sem adicionar o parâmetro obrigatório `needy`, você verá um erro como:

Inicia tu aplicación y ve a <a href="http://127.0.0.1:8000/static/redoc.standalone.js" class="external-link" target="_blank">http://127.0.0.1:8000/static/redoc.standalone.js</a>.

Deberías ver un archivo JavaScript muy largo de **ReDoc**.

Podría comenzar con algo como:

```JavaScript
/*! For license information please see redoc.standalone.js.LICENSE.txt */

        assertTrue(exception.getMessage().contains("State error"));
    }

    public void test_constructor_withLongMessage() {

        final StringBuilder longMessage = new StringBuilder();
        for (int i = 0; i < 1000; i++) {
            longMessage.append("Long message part ").append(i).append(" ");
        }

        assertTrue(toStringResult.contains(SsoLoginException.class.getName()));
        assertTrue(toStringResult.contains(message));
    }

    public void test_longMessage() {
        // Test with very long message
        StringBuilder longMessage = new StringBuilder();
        for (int i = 0; i < 1000; i++) {
            longMessage.append("Long SSO error message part ").append(i).append(" ");
