A `Request` also has a `request.receive`, that's a function to "receive" the body of the request.

The `scope` `dict` and `receive` function are both part of the ASGI specification.

And those two things, `scope` and `receive`, are what is needed to create a new `Request` instance.

        assertNotNull(capabilities, "Capabilities should not be null");
        assertEquals(1, capabilities.size(), "TCP provider should only support send/receive");
        assertTrue(capabilities.contains(RdmaCapability.RDMA_SEND_RECEIVE), "Should support send/receive");
        assertFalse(capabilities.contains(RdmaCapability.RDMA_READ), "Should not support RDMA read");

        assertEquals(1, cleaned);
        assertNull(leaseManager.getLease(key));
    }

    @Test
    @DisplayName("Should not clean up recent leases")
    void testCleanupRecentLeases() {
        String path = "/share/recent.txt";
        int requestedState = Smb2LeaseState.SMB2_LEASE_READ_CACHING;

        Smb2LeaseKey key = leaseManager.requestLease(path, requestedState);

In your WebSocket route you can `await` for messages and send messages.

You can receive and send binary, text, and JSON data.

If your file is named `main.py`, run your application with:

<div class="termy">

```console

`PUT` is used to receive data that should replace the existing data.

### Warning about replacing { #warning-about-replacing }

That means that if you want to update the item `bar` using `PUT` with a body containing:

```Python
{

        // Verify the result
        assertEquals(len, result, "readDataWireFormat should return the length of data read.");

        // Verify that the receive method on the input stream was called exactly once
        verify(mockPipeIn, times(1)).receive(buffer, bufferIndex, len);
    }

Un `Request` también tiene un `request.receive`, que es una función para "recibir" el cuerpo del request.

El `dict` `scope` y la función `receive` son ambos parte de la especificación ASGI.

Y esas dos cosas, `scope` y `receive`, son lo que se necesita para crear una nueva *Request instance*.
