You might also get a pong without ever sending a ping; ignore this if it happens. We’ll use Websockets to take JSON-RPC requests. It should respond to “ping” with “pong”. Install websockets to take requests and jsonrpcserver to process them: $ pip install websockets jsonrpcserver pong_waiter = await ws.

The number of WebSocket messages sent by the … 2018-10-29 If client and server both use the same library, the PING and PONG frame not send automatically, when one side want to check if another side is still online, it send a PING frame by calling the ping() method from user, another side auto reply the PING frame by call the pong() method internally, so we don't need to take care about incoming PING frame and call pong() by our self. Whenever we receive a PING frame, we have to reply with a PONG frame with a payload identical to the one present in the received PING. we reuse the function send_text() to send the pong frame but add the opcode to be sent as an argument. This opcode defaults to OPCODE_TEXT so we do not break the compatibility.

wsproto is a WebSocket protocol stack written to be as flexible as possible. To that end it is written in pure Python and performs no I/O of its own. Instead it relies on the user to provide a bridge between it and whichever I/O mechanism is in use, allowing it to be used in single-threaded, multi-threaded or event-driven code.

This payload may be overridden with the optional ``data`` argument which must be a string (which will be encoded to UTF-8) or a bytes-like object websocket-client is a WebSocket client for Python. It provides access to low level APIs for WebSockets. websocket-client implements version hybi-13 of the WebSocket procotol.

And I imagine a dedicated ping/pong message frame could be simpler (less load on 2018-05-21 2019-06-10 2019-07-25 (C#) Send a WebSocket Ping Control Frame. Ping and Pong messages are the heartbeat of websockets. See Pings and Pongs "At any point after the handshake, either the client or the server can choose to send a ping to the other party. When the ping is received, the recipient must send back a pong as soon as possible. You can use this to make sure If your websocket library supports hybi-13, or ping/pong, you may send a ping at any time and the server will return with a pong. Due to changes in browser power-saving modes, we no longer support expectant pings via the WebSocket API. If you are concerned about your connection silently dropping, we recommend implementing the following flow: After receiving each message, set a timer a duration Heartbeat (Ping - Pong) message.

Indeed, websockets doesn't handle well the situation where a ping is aborted because the connection was lost. As noted by @Harmon758 in this bug report, this could manifest in two places: When websockets aborts a ping that the keepalive task is waiting on; When websockets processes a pong that matches an aborted ping.
