## Await for messages and send messages { #await-for-messages-and-send-messages }

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

{* ../../docs_src/websockets/tutorial001.py hl[48:52] *}

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

## Try it { #try-it }

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

        assertTrue(pattern.match("/test/path"));

        // Should match second included path
        assertTrue(pattern.match("/another/path"));

        // Should not match first excluded path
        assertFalse(pattern.match("/exclude/path"));

        // Should not match second excluded path
        assertFalse(pattern.match("/deny/path"));
    }

        // Encode from first instance
        byte[] encodedBuffer = new byte[8];
        firstInstance.encode(encodedBuffer, 0);

        // Decode into second instance
        FileInternalInfo secondInstance = new FileInternalInfo();
        secondInstance.decode(encodedBuffer, 0, encodedBuffer.length);

        // Verify both instances have same values

            return command;
        }

        @Override
        public void setCommand(int command) {
            this.command = command;
        }

        @Override
        public void setUid(int uid) {
            // No-op for test
        }

        @Override
        public void setExtendedSecurity(boolean extendedSecurity) {
            // No-op for test
        }

        @Override

   * - The first request "wins the race".
   * - The second request discovers it "lost the race" and closes the connection it just opened.
   * - The second request uses the coalesced connection from request1.
   * - The coalesced connection is violently closed after servicing the first request.
   * - The second request discovers the coalesced connection is unhealthy just after acquiring it.

# Request Body { #request-body }

When you need to send data from a client (let's say, a browser) to your API, you send it as a **request body**.

A **request** body is data sent by the client to your API. A **response** body is the data your API sends to the client.
