As this is a WebSocket it doesn't really make sense to raise an `HTTPException`, instead we raise a `WebSocketException`.

You can use a closing code from the [valid codes defined in the specification](https://tools.ietf.org/html/rfc6455#section-7.4.1).

### Try the WebSockets with dependencies { #try-the-websockets-with-dependencies }

Run your application:

* `expose_headers` - Indica quaisquer cabeçalhos de resposta que devem ser disponibilizados ao navegador. O padrão é `[]`.
* `max_age` - Define um tempo máximo em segundos para os navegadores armazenarem em cache as respostas CORS. O padrão é `600`.

O middleware responde a dois tipos específicos de solicitação HTTP...

        StackTraceElement[] stackTrace = exception.getStackTrace();
        assertEquals(0, stackTrace.length);
    }

    @Test
    public void test_serialVersionUID() {
        // Test that serialVersionUID is correctly defined
        UserRoleLoginException exception = new UserRoleLoginException(RootAction.class);
        // Verify exception is serializable
        assertTrue(exception instanceof java.io.Serializable);
    }

    @Test

 * string {@code "Foo<Bar>"}.
 *
 * <p>A {@code CharEscaper} instance is required to be stateless, and safe when used concurrently by
 * multiple threads.
 *
 * <p>Popular escapers are defined as constants in classes like {@link
 * com.google.common.html.HtmlEscapers} and {@link com.google.common.xml.XmlEscapers}. To create
 * your own escapers extend this class and implement the {@link #escape(char)} method.

So, a Python class is also a **callable**.

Then, in **FastAPI**, you could use a Python class as a dependency.

What FastAPI actually checks is that it is a "callable" (function, class or anything else) and the parameters defined.

If you pass a "callable" as a dependency in **FastAPI**, it will analyze the parameters for that "callable", and process them in the same way as the parameters for a *path operation function*. Including sub-dependencies.

# When cross-compiling with RBE, we need to copy the macOS sysroot to be
# inside the TensorFlow root directory. We then define them as a filegroup
# target inside "tensorflow/tools/toolchains/cross_compile/cc" so that Bazel
# can register it as an input to compile/link actions and send it to the remote
# VMs when needed.

            // Verify expected fields exist
            assertTrue("Should contain text field", mappings.contains("text"));
            assertTrue("Should define field types", mappings.contains("type"));

Donc, dans OpenAPI, chacune des méthodes HTTP est appelée une « opération ».

Nous allons donc aussi les appeler « opérations ».
