The Websocket online testing tool provides you with socket online testing, Websocket online detection, and Websocket online testing to see if the server Websocket function is available. It supports intranet and extranet Websocket testing: the connection format is ws://IP or domain name:port (example ws: //127.0.0.1:8080), mainly uses Html5 Websocket to connect to the Websocket of the server, so you can use this Websocket testing tool whether you are in an internal network environment or an external network environment. I hope it will be helpful to everyone.
