A second window opened from the main one (window.open(...)) which gets a webcam stream and draws it on a canvas. I need to draw the same canvas, realtime, on the canvas in the main window.

This all

Does anyone know of a wireshark filter that would accomplish what I need and if I need to do anything else to monitor secure websockets using wireshark? 回答1: If you want to monitor a WebSocket connection between the browser

How to override WebSocket send() method

由 99封情书 提交于 2021-01-01 17:54:02
问题 I'm trying to override the WebSocket.send() method. My objective is being able to fuzz the sent data to test robustness of the server implementation.

This UDP Server carries the Eye Coordinate data and sends it to the UDP Client which I have merged with the Websocket Server that is communicating with a
