if __name__ == '__main__':

    postman = 'http://postman-echo.com/get'

    app = QApplication(sys.argv)
    browser = Browser(bet365)
    sys.exit(app.exec_())

这是浏览器代码，它应该只是打开页面 bet365.com 但问题是页面没有加载，程序窗口变成白色，而其他站点，如 2ip.ru 已加载并显示我的 IP。我该怎么做才能让 bet365 正确回答我？

另外，当我像这样设置 Host 标头时 httpReq.setHeader(QByteArray(b'Host'), QByteArray(b'www.bet365.com'))，代码 ERR_INVALID_ARGUMENT 出现错误，我认为在请求时它仍然与标头有关，但不，我设置了不同的标头并且没有运气。
