i want change HttpHeader with setHttpHeader but not work

@jsulm no, i checked it now but not work

Then that means that

@KHOSRO Sorry, I don't really understand what you mean.
Is setHttpHeader() called or not?And please format your code properly.

@KHOSRO In the code you posted you do not do anything inside setHttpHeader.

@jsulm
I don't know the answer to this, but what OP shows forQWebEngineUrlRequestInfoandsetHttpHeader()etc. is not code he has written, it is Python/PySide's way of showing howQWebEngineUrlRequestInfo()is defined from Python point of view. You can assume it is actually calling the C++QWebEngineUrlRequestInfomethods.@KHOSRO
I don't understand what you are doing when you showdef setHttpHeader(self, name, PySide6_QtCore_QByteArray=None, bytes=None, *args, **kwargs): # real signature unknown; NOTE: unreliably restored from __doc__ """ setHttpHeader(self, name: Union[PySide6.QtCore.QByteArray, bytes], value: Union[PySide6.QtCore.QByteArray, bytes]) -> None """ print('Hiiiiiiiiiiiiiii') passWhere have you made the edit to add your
print()? You are not supposed to be redefining (def)setHttpHeader()you are supposed to be calling it with whatever you want. Like you show withinfo.setHttpHeader(QByteArray(b'Cache-Control'), QByteArray(b'public,max-age=10000000'))QWebEngineUrlRequestInfo::setHttpHeader()is notvirtualso you cannot override it (e.g. to add in yourprint()), you can only call it. -
@JonB thank u for ur response
do u have idead
why QWebEngineUrlRequestInfo and setHttpHeader() not work when called
and can not change the header
in detail:
i have a client which is qwebengine
i send request url to server when fetch it i want change cache- control for custom purpose
after changing url , i want to show downloaded url -
I don't know anything about it, but my guess is that it is changing the header, but you are not seeing the effect you expect/desire. What evidence do you have that it is not setting your header? After calling
setHttpHeader()if you are Qt 6.5+ try calling QHash<QByteArray, QByteArray> QWebEngineUrlRequestInfo::httpHeaders() const to at least make sure yourCache-Controlheader is there. Or try sniffing/checking what is received at server side.
