Qwebengineview intercepting URL Request settings

The Qwebengineurlrequestinterceptor class provides an abstract base class for intercepting URL requests, which can be implemented by Qwebengineurlrequestinterceptor: The Interceptrequest interface intercepts and modifies the corresponding UIL request to achieve the desired effect, such as setting "Accept-language".

Class Twebengineurlrequestinterceptor:public qwebengineurlrequestinterceptor{    q_objectpublic:    Twebengineurlrequestinterceptor (Qobject *parent = q_nullptr);    void Interceptrequest (Qwebengineurlrequestinfo &info);};

Interception Interface Implementation

Info.sethttpheader ("Accept-language", "ZH-CN");}

Interface calls by setting the default Qwebengineprofile property

Twebengineurlrequestinterceptor *webinterceptor = new Twebengineurlrequestinterceptor (); Qwebengineprofile::d efaultprofile ()->setrequestinterceptor (webinterceptor);
