QWebEngineUrlRequestInfo Class

  • Header: QWebEngineUrlRequestInfo

  • CMake:

    find_package(Qt6 REQUIRED COMPONENTS WebEngineCore)

    target_link_libraries(mytarget PRIVATE Qt6::WebEngineCore)

  • qmake: QT += webenginecore

Detailed Description

The QWebEngineUrlRequestInfo is useful for setting extra header fields for requests or for redirecting certain requests without payload data to another URL. This class cannot be instantiated or copied by the user, instead it will be created by Qt WebEngine and sent through the virtual function QWebEngineUrlRequestInterceptor::interceptRequest() if an interceptor has been set.
