标签：Web debugger chrome 9222 port Tools your Developer

官网：
     https://chromedevtools.github.io/devtools-protocol/
     https://developer.chrome.com/extensions/debugger
chrome.exe --remote-debugging-port=9222
Then you can start a separate client Chrome instance, using a distinct user profile:

chrome.exe --user-data-dir=<some directory>

Now you can navigate to the given port from your client and attach to any of the discovered tabs for debugging: http://localhost:9222

You will find the Developer Tools interface identical to the embedded one and here is why:

When you navigate your client browser to the remote's Chrome port, Developer Tools front-end is being served from the host Chrome as a Web Application from the Web Server.
It fetches HTML, JavaScript and CSS files over HTTP
Once loaded, Developer Tools establishes a Web Socket connection to its host and starts exchanging JSON messages with it.

In this scenario, you can substitute Developer Tools front-end with your own implementation. Instead of navigating to the HTML page at http://localhost:9222, your application can discover available pages by requesting: http://localhost:9222/json and getting a JSON object with information about inspectable pages along with the WebSocket addresses that you could use in order to start instrumenting them. See the HTTP Endpoints section below for more.
