# HTTP Basic Auth

Para los casos más simples, puedes usar HTTP Basic Auth.

En HTTP Basic Auth, la aplicación espera un header que contiene un nombre de usuario y una contraseña.

Si no lo recibe, devuelve un error HTTP 401 "Unauthorized".

Y devuelve un header `WWW-Authenticate` con un valor de `Basic`, y un parámetro `realm` opcional.

Eso le dice al navegador que muestre el prompt integrado para un nombre de usuario y contraseña.

Bei HTTP Basic Auth erwartet die Anwendung einen Header, der einen Benutzernamen und ein Passwort enthält.

Wenn sie diesen nicht empfängt, gibt sie den HTTP-Error 401 „Unauthorized“ zurück.

Und gibt einen Header `WWW-Authenticate` mit dem Wert `Basic` und einem optionalen `realm`-Parameter („Bereich“) zurück.

        WebApiException exception1 = new WebApiException(400, "Bad Request");
        WebApiException exception2 = new WebApiException(401, "Unauthorized");
        WebApiException exception3 = new WebApiException(500, "Internal Error");

        assertEquals(400, exception1.getStatusCode());
        assertEquals(401, exception2.getStatusCode());
        assertEquals(500, exception3.getStatusCode());

For the simplest cases, you can use HTTP Basic Auth.

In HTTP Basic Auth, the application expects a header that contains a username and a password.

If it doesn't receive it, it returns an HTTP 401 "Unauthorized" error.

And returns a header `WWW-Authenticate` with a value of `Basic`, and an optional `realm` parameter.

That tells the browser to show the integrated prompt for a username and password.

        verify(servletConfig).getInitParameter("jcifs.smb.client.domain");
        verify(servletConfig).getInitParameter("jcifs.http.enableBasic");
    }

    /**
     * Test doGet with no authentication - should return 401
     */
    @Test
    void testDoGet_NoAuthentication() throws Exception {
        initializeNetworkExplorer(false, "jCIFS");

        when(request.getHeader("Authorization")).thenReturn(null);

/// info | Дополнительная информация
Дополнительный заголовок `WWW-Authenticate` со значением `Bearer`, который мы здесь возвращаем, также является частью спецификации.

Ответ сервера с  HTTP-кодом 401 "UNAUTHORIZED" должен также возвращать заголовок `WWW-Authenticate`.

В случае с bearer-токенами (наш случай) значение этого заголовка должно быть `Bearer`.
