Track onFailure for websocket and check if websocket connection is alive

[naserkaka]

Hi ,

1. how can I check if my websocket connection is open/running ?

2. I wonder if the openEvent,closingEvent and FailureEvent variables can return a value other than null ? I would like to know why my websocket is failing sometimes.

         onOpenCallbackMarket = openEvent -> {
   
        };
         onMessageCallbackMarket = (message) -> {
   
       };
        onClosingCallbackMarket = closingEvent -> {
   
        };
        onFailureCallbackMarket = failureEvent -> { 
   
       };

You can take a look at this example file. It handles callbacks from websocket.

@chairz it just restarts the websocket. Is it possible to get a message why it failed ?

@naserkaka I have proposed a PR about this idea, without knowing you had asked for. Maybe you can review it and see if it fits your needs.

Hi @Hazard4U , this will help a lot , now I can catch the error for failureOnCallback and see more detailed information why it failed. This was needed, thanks! when will this PR be merged?

Hi @naserkaka, according to WebSocketConnection , there's logging for when connection is opened or gets failure.

We'll look into @Hazard4U PR #51 to see how we'll improve this, might take some time though as it might be a breaking change.

so this is how I can catch the message in onFailure ? for now.

 onFailureCallbackMarketDataUser = (message) -> {
                logger.error("onFailureCallback() message:" + message);
            };
