我有一个带有httpPost -attribute的ActionResult。如果我没有弄错，当用户从DateTimePicker中选择日期时，我需要此属性。在我的情况下，我有2个Datetimepickers av类型@ html.EditorFor。这些日期选择器表示我的视图模型中的DateTime属性StartDate和EndDate。在点击＆＃34; GAStatisticsReport-Submit＆＃34;后，可以在Controller和CreateGAStatisticsReport方法中使用这些日期。 CreateGAStatisticsReport按钮的模型为参数。但是在我选择StartDate和EndDate后没有任何反应。
如果从ActionResult GetData中删除HttpPost属性，该方法将按预期运行，但StartDate和EndDate将为Null。我不知道问题是模型绑定，HttpPost，html.BeginForm还是提交按钮的javascript逻辑。尝试各种各样的事情。
我在这里缺少什么？
CreateGAStatisticsListModel：
[NopResourceDisplayName("Admin.GAStatistics.GAStatistics.StartDate")]
[UIHint("DateNullable")]
public DateTime? StartDate { get; set; }
[NopResourceDisplayName("Admin.GAStatistics.GAStatistics.EndDate")]
[UIHint("DateNullable")]
public DateTime? EndDate { get; set; }
GaStatisticsController（当我点击提交按钮时运行GetData）：
[HttpPost]
public ActionResult GetData(GAStatisticsListModel model)
{
return Json(CreateGAStatisticsReport(model), JsonRequestBehavior.AllowGet);
}
public ActionResult GAStatistics()
{
return View(new GAStatisticsListModel());
}
public List<GAStatistics> CreateGAStatisticsReport(GAStatisticsListModel model)
{
var serviceAccountEmail = "xxxxxxxxxxxxxx@developer.gserviceaccount.com";
var certificate = new X509Certificate2(@"C:\Users\user\Desktop\NopCommerce\Presentation\Nop.Web\key.p12", "notasecret", X509KeyStorageFlags.Exportable);
var credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
Scopes = new[] { AnalyticsService.Scope.Analytics }
}.FromCertificate(certificate));
// Create the service.
//Twistandtango
var GoogleAnalyticsService = new AnalyticsService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "Twist",
});
string start = model.StartDate.ToString(); //<----- The model date values are needed here
model.StartDate = DateTime.ParseExact(start, "yyyy-MM-dd", CultureInfo.InvariantCulture);
string end = model.EndDate.ToString(); //<----- The model date values are needed here
model.EndDate = DateTime.ParseExact(end, "yyyy-MM-dd", CultureInfo.InvariantCulture);
var request = GoogleAnalyticsService.Data.Ga.Get("ga:xxxxxxxx", start, end, "ga:visitors");
//Specify some addition query parameters
request.Dimensions = "ga:date";
request.Sort = "-ga:date";
request.MaxResults = 10000;
//Execute and fetch the results of our query
Google.Apis.Analytics.v3.Data.GaData d = request.Execute();
List<GAStatistics> ListGaVisitors = new List<GAStatistics>();
foreach (var row in d.Rows)
{
GAStatistics GaVisits = new GAStatistics(row[0], row[1]);
ListGaVisitors.Add(GaVisits);
}
return ListGaVisitors;
}
查看（问题可能在视图中，需要告诉按钮存储DateTimePickers中选择的日期，以便我可以在控制器中使用它们）：

使用$.get(会发出HttpGet个请求。代码中的目标是'/GAStatistics/GetData'，这是GAStatistics控制器中的GetData操作。但是，该方法标有[HttpPost]，因此不会向get请求公开。
使用$.post(或使用[HttpGet]标记操作。
