PyQt WebEngine set http headers

Question

I want to port my app from Qt WebKit to Qt WebEngine. In Qt Webkit I can set http headers by using QNetworkRequest, but in Qt WebEngine, the doc says:

Qt WebEngine has its own HTTP implementation and cannot go through a QNetworkAccessManager

I use PyQt5 and Qt5.8.

I cannot find how to set http headers in Qt WebEngine.

--------------update----------------

Finally, it worked! Thanks! @Trilarion:

define my QWebEngineUrlRequestInterceptor class

class NWUrlRequestInterceptor(QWebEngineUrlRequestInterceptor):
    def __init__(self, headers):
        super(QWebEngineUrlRequestInterceptor, self).__init__()
        self.headers = headers

    def set_headers(self,headers):
        self.headers = headers

    def interceptRequest(self, info):
        print info, self.headers
        for header, value in self.headers:
            info.setHttpHeader(header, value);

use in my browser:

self.request_interceptor = NWUrlRequestInterceptor(self.headers)
self.webpage.profile().setRequestInterceptor(self.request_interceptor)

You should implement a QWebEngineUrlRequestInterceptor in whose interceptRequest method you get a QWebEngineUrlRequestInfo which can set a http header via setHttpHeader.

Set the request interceptor via QWebEngineView.page().profile().setRequestInterceptor.

Inspired by How to send HTTPHeader using QT WebEngine?.
