Obtaining data from a chrome extension

Question

I have a java application that can create a Socketed lan server to parse information from a website, with the main goal of collecting chat data. At first I was in a test version of that website and was able to just open a web socket in a chrome extension then save it toward the Java server. Now that I have went to the public version of the site where its actually heavily protected, the site has the Content Security Policy, that disallows the use of Web Sockets from chrome extensions. I am unsure if there is any possible way to transfer that chat data from the site to the server via google chrome extension or any other way.

Answer 1

I was trying to open a socket inside of the Website itself. "wOxxOm" gave me a lead that you cannot do that and I later on understood that you had to use websockets in the background.js of the chrome extension.
