从 QWebEngineProfile 获取 cookie 作为字典

Question

标题确实说明了一切。想知道如何将 QWebEngineProfile 的 cookie 作为其名称和值的字典或以 json 格式获取。我正在使用 PyQt5。

QWebEngineCookieStore是一个管理cookies的类，我们可以通过cookieStore()方法访问这个对象，为了获取cookies可以通过cookieAdded信号异步完成，下面我们举个例子：

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_())
