详细描述
The QWebEngineUrlRequestJob class represents a custom URL request.
A QWebEngineUrlRequestJob is given to QWebEngineUrlSchemeHandler::requestStarted() and must be handled by the derived implementations of the class. The job can be handled by calling either reply(), redirect(), or fail().
The class is owned by the web engine and does not need to be deleted. However, the web engine may delete the job when it is no longer needed, and therefore the signal QObject::destroyed() must be monitored if a pointer to the object is stored.
