Remote debug, get remote session ID of the page

[napishu]

Hello. I'm trying to understand where generated the json file http://localhost:9222/json with inspectable pages.


Brackets (code editor) CEF app generated json file like this (for example 2 open window with the same open file):

Code: Select all

[ {
  [ {
   "description": "",
   "devtoolsFrontendUrl": "/devtools/devtools.html?ws=localhost:9234/devtools/page/708612f03a79347c42e53d27eeca9dc4",
   "faviconUrl": "",
   "id": "708612f03a79347c42e53d27eeca9dc4",
   "thumbnailUrl": "/thumb/708612f03a79347c42e53d27eeca9dc4",
   "title": "main.js - Brackets",
   "type": "page",
   "url": "file:///D:/PROGRAMS/Dev/Brackets/www/index.html",
   "webSocketDebuggerUrl": "ws://localhost:9234/devtools/page/708612f03a79347c42e53d27eeca9dc4"
}, {
   "description": "",
   "devtoolsFrontendUrl": "/devtools/devtools.html?ws=localhost:9234/devtools/page/2dcbabfb06f5aafac87c63bc79eaa4d0",
   "faviconUrl": "",
   "id": "2dcbabfb06f5aafac87c63bc79eaa4d0",
   "thumbnailUrl": "/thumb/2dcbabfb06f5aafac87c63bc79eaa4d0",
   "title": "main.js - Brackets",
   "type": "page",
   "url": "file:///D:/PROGRAMS/Dev/Brackets/www/index.html",
   "webSocketDebuggerUrl": "ws://localhost:9234/devtools/page/2dcbabfb06f5aafac87c63bc79eaa4d0"
} ]


So, how from cef app get the id of current window? Can I use the api to get id? And where this json file generated?

Thank you

It comes from the DevTools remote debugger. Run with the '--remote-debugging-port=XXXX' command-line flag. See also https://developer.chrome.com/devtools/d ... r-protocol.

Sorry. Comes what? You do not understand me. I already have access to the json file. How get from active focused windows data for this windows from this json file?

Problem that i don't know how to get information from json file for current focused window. When i open new window - in json file this new window will be listed first. But it is for the newly opened window. Make another window active and I can not get the information from json file on this focused window.

You could use the window's url or title, provided they're different between windows. Why do you need to get json info for the focused window?
