尝试在网页上提交并在ScrapyShart之后获得结果

Question

我正在使用ScrapyShart在网页上提交，但是它不起作用

这是我的代码：

ScrapingBrowser Browser = new ScrapingBrowser();
Browser.AllowAutoRedirect = true;
Browser.AllowMetaRedirect = true;

var url = "https://secure2.lionair.co.id/lionairibe2/OnlineBooking.aspx";

WebPage pageResult = Browser.NavigateToPage(new Uri(url));
PageWebForm form = pageResult.FindFormById("aspnetForm");


form["ctl00$mainContent$UcFlightSelection$TripType"] = "rbReturn";
form["ctl00$mainContent$UcFlightSelection$DateFlexibility"] = "rbMustTravel";
form["ctl00$mainContent$UcFlightSelection$ddlOri"] = "CGK";
form["ctl00$mainContent$UcFlightSelection$ddlDes"] = "DPS";
form["DepartureDate"] ="19 Oct 2018";
form["ReturnDate"] = "24 Oct 2018";
form["ctl00$mainContent$UcFlightSelection$ddlADTCount"] = "1";
form["ctl00$mainContent$UcFlightSelection$ddlCNNCount"] = "0";
form["ctl00$mainContent$UcFlightSelection$ddlINFCount"] = "0";
form["ctl00$mainContent$UcFlightSelection$txtDepartureDate"] = "19 Oct 2018";
form["ctl00$mainContent$UcFlightSelection$txtReturnDate"] = "24 Oct 2018";

form.Method = HttpVerb.Post;
WebPage resulPage = form.Submit();

我从现场检查元素填写表单元素名称和值，我也尝试通过元素ID
