找不到動作只在現場服務器上，在本地服務器工作正常

Question

在控制器 'Flazingo.Controllers.PositionController'找不到公共行動方法'AddPromoCode'。在在 System.Web.Mvc.Controller.ExecuteCore（）在 System.Web.Mvc.ControllerBase.Execute（RequestContext的RequestContext的） System.Web.Mvc.Controller.HandleUnknownAction（字符串actionName）在 的System.Web。 Mvc.MvcHandler。 <> c__DisplayClass6。 <> c__DisplayClassb.b__5（） at System.Web.Mvc.Async.AsyncResultWrapper。 <> c__DisplayClass1.b__0（） at System.Web.Mvc.MvcHandler。 <> c__DisplayClasse.b__d（）在 System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute（） 在System.Web.HttpApplication.ExecuteStep（IExecutionStep步驟， 布爾& completedSynchronously）

這裏是Ajax調用：

$.ajax({ 
      url: '/Position/AddPromoCode', 
      type: 'POST', 
      dataType: "json", 
      contentType: "application/json; charset:utf-8", 
      data: ko.toJSON(viewModel), 
      success: function(result){ 
       if(result.TypeId == 1){ 
        viewModel.promoOff(viewModel.grandTotal() * (result.Value/100)); 
        viewModel.PromoCodes.push(promoCode + ": "+ result.Value + "% off"); 
       }else{ 
        viewModel.PromoCodes.push(promoCode + ": "+ result.Value + "days free"); 
       } 
      }, 
      error: function (xmlHttpRequest, textStatus, errorThrown) { 
       var errorData = jQuery.parseJSON(xmlHttpRequest.responseText); 
       var errorMessages = []; 
       //this ugly loop is because List<> is serialized to an object instead of an array 
       for (var key in errorData) 
       { 
        errorMessages.push(errorData[key]); 
       } 
       toastr.error(errorMessages.join("<br />"), 'Uh oh'); 
      } 
     }); 

編輯：POST方法

[HttpPost] 
     public ActionResult AddPromoCode(PaymentViewModel model) 
     { 
      List<string> errors = new List<string>(); 
      try 
      { 

       var position = db.Positions.SingleOrDefault(x => x.PositionId == model.PositionId); 
       if (position != null) 
       { 
        var promo = db.Promotions.SingleOrDefault(x => x.Code.ToLower() == model.PromoCode.ToLower() && x.IsUserEntered); 
        if (promo != null) 
        { 
         var promoUsage = db.PromoCodeUsages.SingleOrDefault(x => x.PromotionId == promo.PromotionId && x.ClientId == position.Client.Id); 
         int used = 0; 
         if (promoUsage != null) 
         { 
          used = promoUsage.Used; 
         } 

         if (used < promo.QuantityUsage) 
         { 
          if (DateTime.Today >= promo.StartDate && DateTime.Today <= promo.EndDate) 
          { 
           position.PromoCodes.Add(new PositionPromoCode 
           { 
            PromotionId = promo.PromotionId 
           }); 

           var clientPC = position.Client.PromoCodes.SingleOrDefault(x => x.PromotionId == promo.PromotionId); 
           if (clientPC != null) 
           { 
            clientPC.Used = used + 1; 
           } 
           else 
           { 
            clientPC = new PromoCodeUsage() 
            { 
             PromotionId = promo.PromotionId, 
             Used = used + 1 
            }; 
            position.Client.PromoCodes.Add(clientPC); 
           } 

           db.SaveChanges(); 

           Response.StatusCode = (int)HttpStatusCode.OK; 
           return Json(new { Value = promo.Value, TypeId = promo.PromotionTypeId }); 

          } 
          else 
          { 
           Response.StatusCode = (int)HttpStatusCode.BadRequest; 
           errors.Add("Sorry seems like this promotion code has expired"); 
           db.SaveChanges(); 
           return Json(errors); 
          } 
         } 
         else 
         { 
          Response.StatusCode = (int)HttpStatusCode.BadRequest; 
          errors.Add("Sorry seems like you have already used this code, or its not applicable anymore!"); 
          db.SaveChanges(); 
          return Json(errors); 
         } 
        } 
        else 
        { 
         Response.StatusCode = (int)HttpStatusCode.BadRequest; 
         errors.Add(string.Format("Sorry we don't have '{0}' promocode in our system!", model.PromoCode)); 
         db.SaveChanges(); 
         return Json(errors); 
        } 
       } 

       Response.StatusCode = (int)HttpStatusCode.BadRequest;

       db.SaveChanges(); 
       return Json(errors); 
      } 
      catch (Exception ex)

       logger.Log(LogLevel.Error, string.Format("{0} \n {1}", ex.Message, ex.StackTrace)); 
       Response.StatusCode = (int)HttpStatusCode.BadRequest;

Answer 1

它找不到AddPromoCode所以，似乎有一個URL的問題。您應該在服務器中的阿賈克斯代碼中添加應用程序名稱，如url: '/ApplicationName/Position/AddPromoCode'。

您還可以url.action HTML幫助做到這一點，如：

// In layout or view: 
@Html.Hidden("urlPrefix", Url.Action("", "")) 

// In Javascript 
var baseUrl = $("input#urlPrefix").val(); 

$.ajax({ url: baseUrl + '/Position/AddPromoCode', ... 

的部分Url.Action("", "")創建'/ApplicationName'部分動態。
