How to disable CSP in qt webengine?

I'm using QWebEngine with Qt5.9.1.

I want to inject webchannel and user script into some web page to communicate with my c++ code.

But there's always some alerting:

"[63092:96096:1015/025540.965:INFO:CONSOLE(438)] "Refused to connect to 'ws://127.0.0.1:12343/' because it violates the following Content Security Policy directive".

And user script cann't execute, too.

I have tried to disable Content Security Policy by:

page->settings()->setAttribute(QWebEngineSettings::XSSAuditingEnabled, false);

But this didn't work.

How should I disable CSP in qt webengine?

Solution

  • I found a solution:

    I changed the address from ws://127.0.0.1:12343/ to ws://localhost:12343/. The web channel can connect successfully.

    I don't know the reason, but it works.
