Unsolved Webengine load glyphicons from bootstrap is not allowed

[webberg]

Hello,
I add bootstrap.min.css to qrc, and put glyphicons files in ../fonts where the bootstrap points to. In webengine I code the html header <link href='qrc:/qml/js/bootstrap.min.css' rel='stylesheet'>. But I get the consolse info:

js: Font from origin 'qrc://' has been blocked from loading by Cross-Origin Resource Sharing policy: Invalid response. Origin 'null' is therefore not allowed access.
[0311/101100:INFO:CONSOLE(0)] "Font from origin 'qrc://' has been blocked from loading by Cross-Origin Resource Sharing policy: Invalid response.

I don't know how to solve this issue. I try to put fonts folder in project's parent dir but stiil not work.
