Par exemple, pour déclarer un en-tête `X-Token` qui peut apparaître plusieurs fois, vous pouvez écrire :

{* ../../docs_src/header_params/tutorial003_an_py310.py hl[9] *}

Si vous communiquez avec ce *chemin d'accès* en envoyant deux en-têtes HTTP comme :

```
X-Token: foo
X-Token: bar
```

La réponse ressemblerait à ceci :

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}

        // Test constructor with whitespace in type
        String type = "  Bearer Token  ";
        String message = "Whitespace in token type";
        InvalidAccessTokenException exception = new InvalidAccessTokenException(type, message);

        assertEquals("  Bearer Token  ", exception.getType());
        assertEquals(message, exception.getMessage());
        assertNull(exception.getCause());

            <property name="option" value="statement"/>
            <property name="tokens" value="LITERAL_DO,LITERAL_ELSE,LITERAL_FINALLY,LITERAL_IF,LITERAL_FOR,LITERAL_TRY,LITERAL_WHILE,INSTANCE_INIT,STATIC_INIT"/>
        </module>
        <module name="EmptyBlock">
            <property name="option" value="text"/>
            <property name="tokens" value="LITERAL_CATCH"/>
        </module>
        <module name="AvoidNestedBlocks">

Das ist derselbe Mechanismus, der verwendet wird, wenn Sie beim Anmelden mit Facebook, Google, GitHub, usw. Berechtigungen erteilen:

## Возврат токена { #return-the-token }

Ответ операции пути `/token` должен быть объектом JSON.

В нём должен быть `token_type`. В нашем случае, поскольку мы используем токены типа "Bearer", тип токена должен быть `bearer`.
