QWebSocket client example#
A sample WebSocket client that sends a message and displays the message that it receives back.
The EchoClient example implements a WebSocket client that sends a message to a WebSocket server and dumps the answer that it gets back. This example should ideally be used with the EchoServer example.
We start by connecting to the `connected()` signal.
def __init__(self, url, debug, parent): QObject(parent), m_url(url), m_debug(debug) if m_debug: print("WebSocket server:", url) m_webSocket.connected.connect(self.onConnected) m_webSocket.disconnected.connect(self.closed) m_webSocket.open(QUrl(url))
After the connection, we open the socket to the given
def onConnected(self): if m_debug: print("WebSocket connected") m_webSocket.textMessageReceived.connect( self.onTextMessageReceived) m_webSocket.sendTextMessage("Hello, world!")
When the client is connected successfully, we connect to the `onTextMessageReceived()` signal, and send out “Hello, world!”. If connected with the EchoServer, we will receive the same message back.
def onTextMessageReceived(self, message): if m_debug: print("Message received:", message) m_webSocket.close()
Whenever a message is received, we write it out.
