如何使用WKWebView / WKHTTPCookieStore在应用程序重新启动时保留cookies

if let cookies = HTTPCookieStorage.shared.cookies {
    for cookie in cookies {
        WKWebsiteDataStore.default().httpCookieStore.setCookie(cookie, completionHandler: nil)
    }
}

NotificationCenter.default.addObserver(forName: UIApplication.willResignActiveNotification, object: nil, queue: nil) { _ in
    WKWebsiteDataStore.default().httpCookieStore.getAllCookies { cookies in
        if let cookies = cookies {
            let data = NSKeyedArchiver.archivedData(withRootObject: cookies)
            UserDefaults.standard.set(data, forKey: "SavedCookies")
        }
    }
}

if let data = UserDefaults.standard.data(forKey: "SavedCookies"),
   let cookies = NSKeyedUnarchiver.unarchiveObject(with: data) as? [HTTPCookie] {
    for cookie in cookies {
        WKWebsiteDataStore.default().httpCookieStore.setCookie(cookie, completionHandler: nil)
    }
}
