Using Google Chrome remote debugging protocol

Question

I need to get the network events from Chrome. I\'ve found this: https://developer.chrome.com/devtools/docs/debugger-protocol https://developer.chrome.com/devtools/docs/proto

Finally I've got it. Credit goes to https://www.igvita.com/2012/04/09/driving-google-chrome-via-websocket-api/.

First I send an HTTP request to http://localhost:9222/json. This returns a JSON list of open tabs in Chrome, for each I also get a WebSocket uri (webSocketDebuggerUrl):

[
{
"description": "",
"devtoolsFrontendUrl": "/devtools/devtools.html?ws=localhost:9222/devtools/page/C014A09F-BD0A-40BA-B23C-7B18B84942CD",
"faviconUrl": "http://cdn.sstatic.net/stackoverflow/img/favicon.ico?v=00a326f96f68",
"id": "C014A09F-BD0A-40BA-B23C-7B18B84942CD",
"title": "Using Google Chrome remote debugging protocol - Stack Overflow",
"type": "page",
"url": "https://stackoverflow.com/questions/28430479/using-google-chrome-remote-debugging-protocol",
"webSocketDebuggerUrl": "ws://localhost:9222/devtools/page/C014A09F-BD0A-40BA-B23C-7B18B84942CD"
}
]

Then I can use WebSocket to send messages for debugging a specific tab, using this URI. I also found this for using Jetty implementation of WebSocket: javax.websocket client simple example.
