QWebEngineCookieStore 是管理cookie的类并且我们可以通过 cookieStore（）方法访问此对象，为了获取cookie，可以通过 cookieAdded 信号，在下面的部分中，我们将显示一个示例：

QWebEngineCookieStore is a class that manages cookies and we can access this object through the cookieStore() method, in order to obtain cookies it can be done asynchronously through the cookieAdded signal, in the following part we show an example:

class MainWindow(QMainWindow):
    def __init__(self, *args, **kwargs):
        QMainWindow.__init__(self, *args, **kwargs)
        self.webview = QWebEngineView()
        profile = QWebEngineProfile("storage", self.webview)
        cookie_store = profile.cookieStore()
        cookie_store.cookieAdded.connect(self.onCookieAdded)
        self.cookies = []
        webpage = QWebEnginePage(profile, self.webview)
        self.webview.setPage(webpage)
        self.webview.load(
            QUrl("https://stackoverflow.com/questions/48150321/obtain-cookies-as-dictionary-from-a-qwebengineprofile"))
        self.setCentralWidget(self.webview)

    def onCookieAdded(self, cookie):
        for c in self.cookies:
            if c.hasSameIdentifier(cookie):
                return
        self.cookies.append(QNetworkCookie(cookie))
        self.toJson()

    def toJson(self):
        cookies_list_info = []
        for c in self.cookies:
            data = {"name": bytearray(c.name()).decode(), "domain": c.domain(), "value": bytearray(c.value()).decode(),
                    "path": c.path(), "expirationDate": c.expirationDate().toString(Qt.ISODate), "secure": c.isSecure(),
                    "httponly": c.isHttpOnly()}
            cookies_list_info.append(data)
        print("Cookie as list of dictionary:")
        print(cookies_list_info)


if __name__ == '__main__':
    app = QApplication(sys.argv)
    w = MainWindow()
    w.show()
    sys.exit(app.exec_())
