CEF cannot package local resources (html, js, css, img), can only expose them under the program path. This sentence is wrong!
this view is wrong, and you really can"t package it by using the basic method of relative path + registering the class to the browser. However, by adding resources to program resources, binary resources can be provided to cef browsers in the form of streams by wrapping requests and responses in SchemeHandler.

how do you do this? How can I package local html,js,css and other resources together?
