Question

A public action method 'AddPromoCode' was not found on controller 'Flazingo.Controllers.PositionController'. at System.Web.Mvc.Controller.HandleUnknownAction(String actionName) at System.Web.Mvc.Controller.ExecuteCore() at System.Web.Mvc.ControllerBase.Execute(RequestContext requestContext) at 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() at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

这是 ajax 调用:

$.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');
            }
        });

Answer 1

找不到AddPromoCode，因此，似乎存在网址问题。您应该在服务器中的 ajax 代码处添加应用程序名称，例如 url: '/ApplicationName/Position/AddPromoCode'。

您还可以使用 url.action html 帮助程序来执行此操作，例如:

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

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

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

Url.Action("", "") 部分动态创建 '/ApplicationName' 部分。
