我找到了一个解决方案,通过使用 QWebEngineCookieStore 与 QWebEngine 和 QNetworkAccesManager 共享 Cookie。子类 QNetworkCookieJar:
class CookieWebEngine : public QNetworkCookieJar
{
.....
protected:
// Reimplement this functions to work with your _cookies list;
bool insertCookie(const QNetworkCookie &cookie);
bool deleteCookie(const QNetworkCookie &cookie);
bool updateCookie(const QNetworkCookie &cookie);
bool validateCookie(const QNetworkCookie &cookie, const QUrl &url) const;
private:
// Save Chromium Cookies
QWebEngineCookieStore *_store;
// Save available cookies
QList<QNetworkCookie> _cookies;
}
现在,让我们实现一个函数来在文件中加载/保存 cookie:
// Load Chromium Cookies
void CookieWebEngine::loadStore() {
// Save cookies profile shared
QWebEngineProfile::defaultProfile()->setPersistentCookiesPolicy(QWebEngineProfile::ForcePersistentCookies);
_store = WebEngineProfile::defaultProfile()->cookieStore();
connect(_store, &QWebEngineCookieStore::cookieAdded, this, &CookieWebEngine::handleCookieAdded);
_store->loadAllCookies();
}
// Load/Save cookies in arraylist in a file
void CookieWebEngine::load() {
// load cookies and exceptions
qRegisterMetaTypeStreamOperators<QList<QNetworkCookie> >("QList<QNetworkCookie>");
const QString location = cookiesDirectory() + COOKIES_FILE;
QSettings cookieSettings(location, QSettings::IniFormat);
_cookies = qvariant_cast<QList<QNetworkCookie> >(cookieSettings.value(QLatin1String("cookies")));
setAllCookies(_cookies);
// Now user iterate and add it to chromium
for (auto cookie : _cookies) {
_store->setCookie(cookie);
}
cookieSettings.sync();
}
void CookieWebEngine::save()
{
QString directory = cookiesDirectory();
if (!QFile::exists(directory)) {
QDir dir;
dir.mkpath(directory);
}
const QString location = directory + COOKIES_FILE;
QSettings cookieSettings(location, QSettings::IniFormat);
cookieSettings.setValue(QLatin1String("cookies"), QVariant::fromValue<QList<QNetworkCookie>>(_cookies));
cookieSettings.sync();
}
现在,只需连接并处理从 webview 加载的 cookie:
void CookieWebEngine::handleCookieAdded(const QNetworkCookie &cookie)
{
if (insertCookie(cookie)) {
qDebug() << "Handle cookie " << cookie;
}
}
它对我来说效果很好。现在,我使用 chromium 登录。之后,我将会话 cookie 保存在自定义的 cookiejar 中,并在自定义的 QNetworkAccesManager 中使用它。
