P2: Important When visiting https://httpbin.io/redirect-to?url=https://httpbin.io/headers and setting a custom User-Agent header via QWebEngineUrlRequestInterceptor (so that the header can be overridden differently for different websites), since Qt 6.5 the header does not get applied after a redirect. Other headers seem to be set correctly.
Minimal example:
#include <QApplication> #include <QWebEngineView> #include <QWebEngineProfile> #include <QWebEngineUrlRequestInterceptor> #include <QWebEngineUrlRequestInfo> #include <QTimer> #include <QUrl> class RequestInterceptor : public QWebEngineUrlRequestInterceptor { public: using QWebEngineUrlRequestInterceptor::QWebEngineUrlRequestInterceptor; void interceptRequest(QWebEngineUrlRequestInfo &info) override { info.setHttpHeader("X-Test", "test-value"); info.setHttpHeader("Accept", "test-value"); info.setHttpHeader("User-Agent", "test-value"); } }; int main(int argc, char *argv[]) { QApplication app(argc, argv); auto interceptor = new RequestInterceptor(&app); QWebEngineProfile::defaultProfile()->setUrlRequestInterceptor(interceptor); auto wv = new QWebEngineView; wv->load(QUrl("https://httpbin.io/redirect-to?url=https://httpbin.io/headers")); wv->show(); QTimer::singleShot(5000, wv, &QWebEngineView::reload); return app.exec(); }
QT += widgets webenginewidgets SOURCES += headers.cpp TARGET = headers
Before the refresh:
"Accept": [
"test-value"
],
"User-Agent": [
"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) QtWebEngine/6.9.2 Chrome/130.0.0.0 Safari/537.36"
],
"X-Test": [
"test-value"
],
after the refresh:
"Accept": [
"test-value"
],
"User-Agent": [
"test-value"
],
"X-Test": [
"test-value"
],
