在C＃core 2.1中的SOAP服务之间共享cookie

Question

我正在尝试通过使用多个端点的SOAP连接到应用程序。 通过Cookie进行身份验证。因此，我希望绑定上的AllowCookies选项为将来的调用设置cookie。这似乎从未奏效。

    public MyService(IPreferences preferences)
    {
        // Create binding for end-point 1
        _binding = new BasicHttpBinding {AllowCookies = true};
        _remoteAddress = new EndpointAddress("http://web.server.com/end-point-1");
        ChannelFactory<LoginService> factory = new ChannelFactory<LoginService>(_binding, _remoteAddress);
        _loginService = factory.CreateChannel();

        // Use the same binding as for the first channel
        _remoteAddress = new EndpointAddress("http://web.server.com/end-point-2");
        ChannelFactory<DataSerivce> factory2 = new ChannelFactory<DataSerivce>(_binding, _remoteAddress);
        _dataSerivce = factory2.CreateChannel();

        _preferences = preferences;

        Login();
    }

    // Login & test if data fetch is possible
    public async Task Login()
    {
        loginRequest input = new loginRequest
        {
            LoginInput = new LoginInput
            {
                username = _preferences.Username,
                password = _preferences.Password,
                group = "group1"
            }
        };
        await _loginService.loginAsync(input);


        exportDataRequest exportDataRequest = new exportDataRequest
        {
            ExportDataInput = new ExportDataInput
            {
                xmlFileName = "export.xml",
                exportObjects = new[] {new ModelObject {uid = "BiLAAASe43wGrD"}}}
        };
        // this throws an exception for not being logged in
        await _dataSerivce.exportDataAsync(exportDataRequest);
    }

我正在寻找某种方式来手动获取cookie并将其移至其他服务。
