is there any way to send data to websocket from after method??
like sending x data when i receive y data.
Before wsHook:
WebSocket.OPEN
1
After wsHook:
WebSocket.OPEN
undefined
I have this code to inject the script into the page once loaded. I can access wsHook from the console, however before/after never trigger.
Am I missing a step or is this not a possible implementation?
window.onload = () => {
// make websocket hook
let websockethook = document.createElement('script');
websockethook.setAttribute('src', 'https://cdn.rawgit.com/skepticfx/wshook/master/wsHook.js');
websockethook.setAttribute('type', 'text/javascript');
document.body.appendChild(websockethook);
wsHook.before = function (data, url) {
console.log("Sending message to " + url + " : " + data);
console.log(1)
return data;
}
// Make sure your program calls `wsClient.onmessage` event handler somewhere.
wsHook.after = function (messageEvent, url, wsObject) {
console.log("Received message from " + url + " : " + messageEvent.data);
return messageEvent;
}
};
Neither Hookish nor WsHook seem to detect WebSockets on skribble.io inside of a userscript

wsHook.after = function(messageEvent, url, wsObject) {
console.log("Received message from " + url + " : " + messageEvent.data);
return messageEvent;
}
I assume they are capturing the WebSocket object somehow, but I have not been able to figure out where at this point.
I will conduct further research on this, but would be very happy about your help, as you probably have more experience.
