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.

gradlew -p benchmarks/ run --args 'RoundingBenchmark.round -prounder=es -prange="2000-10-01 to 2000-11-01" -pzone=America/New_York -pinterval=10d -pcount=1000000'
```

The benchmark code defines default values for the parameters so if
you leave out any out JMH will run with each default value, one after
the other. This will run with `interval` set to `calendar year` then
`calendar hour` then `10d` then `5d` then `1h`:

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

        // Test settings content
        try (InputStream is = getClass().getClassLoader().getResourceAsStream("suggest_indices/suggest.json")) {

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

Nous allons donc aussi les appeler « opérations ».
