setHttpHeader not wok in QWebEngineUrlRequestInfo

KHOSRO

@jsulm no, i checked it now but not work
```

def 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')
        pass

it can not print 'Hiiiiiii'

jsulm

Then that means that

if info.resourceType() == QWebEngineUrlRequestInfo.ResourceTypeImage

is never true.

KHOSRO

@jsulm yesss
this condition satisfy and it is

print(info.resourceType())
        if info.resourceType() == QWebEngineUrlRequestInfo.ResourceTypeImage:
            # Set custom cache control
            info.setHttpHeader(b'Cache-Control', b'max-age=31536000')

outpu is :
PySide2.QtWebEngineCore.QWebEngineUrlRequestInfo.ResourceType.ResourceTypeImage

@KHOSRO Sorry, I don't really understand what you mean.
Is setHttpHeader() called or not?

And please format your code properly.

KHOSRO

@jsulm i correct and edite above code
please check another
yes it call method

KHOSRO

@jsulm do u have any idea Sir

jsulm

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

JonB

@jsulm
I don't know the answer to this, but what OP shows for QWebEngineUrlRequestInfo and setHttpHeader() etc. is not code he has written, it is Python/PySide's way of showing how QWebEngineUrlRequestInfo() is defined from Python point of view. You can assume it is actually calling the C++ QWebEngineUrlRequestInfo methods.

@KHOSRO
I don't understand what you are doing when you show

def 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')
        pass

Where 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 with

info.setHttpHeader(QByteArray(b'Cache-Control'), QByteArray(b'public,max-age=10000000'))

QWebEngineUrlRequestInfo::setHttpHeader() is not virtual so you cannot override it (e.g. to add in your print()), you can only call it.

KHOSRO

@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

JonB

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 your Cache-Control header is there. Or try sniffing/checking what is received at server side.
