Question

这是我第一次使用Knockout使用WCF服务。我想将整个视图模型作为带有ajax调用的JSON对象进行POST。

这是我收到的错误消息：

使用'UriTemplate'的端点不能与之一起使用 'System.ServiceModel.Description.WebScriptEnablingBehavior'

我注意到一些开发人员将每个值作为参数发送，我觉得这是不必要的，特别是如果你使用一个大对象。

这是我的WCF方法：

[OperationContract]
    [WebInvoke(UriTemplate = "AddNewEvent?newEvent", Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
    public bool AddNewEvent(Models.DAL_CRMEvents newEvent)
    {
        Entities.CRMEntities dbCRM = new Entities.CRMEntities();
        //Models.CRMEvents crmEvent = new Models.CRMEvents();
        Entities.Event crmEvent = new Entities.Event();



        crmEvent.EventDateCreated = Convert.ToDateTime(newEvent.DateCreated);
        crmEvent.EventActive = true;
        crmEvent.EventDescription = newEvent.Description;
        crmEvent.EventDate = Convert.ToDateTime(newEvent.Date);
        crmEvent.EventTimeStart = TimeSpan.Parse(newEvent.TimeStart);
        crmEvent.EventTimeEnd = TimeSpan.Parse(newEvent.TimeEnd);
        crmEvent.EventAllDay = newEvent.AllDay;

        dbCRM.AddToEvent(crmEvent);

        return true;
    }

这是我的ajax功能

function SaveEvent (data) {
        var s = {
            newEvent: ko.mapping.toJS(data)
        }


        alert(data.AllDay());
        $.ajax({
            type: "POST",
            url: "../Services/CRMDataService.svc/AddNewEvent",
            data: JSON.stringify(s),
            contentType: "application/json; charset=utf-8",
            dataType: "JSON",
            success: function (result) {
                alert(result);
            },

            error: function (jqXHR, textStatus, errorThrown) {
                if (textStatus == "error" && errorThrown != "") {
                    var n = noty({
                        text: errorThrown,
                        type: 'warning',
                        dismissQueue: false,
                        modal: true,
                        layout: 'center',
                        theme: 'defaults',
                        callback: {
                        }
                    })
                }
            }
        })
    }

尝试将OperationContract更改为这样......

[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
public bool AddNewEvent(Models.DAL_CRMEvents newEvent)

有人posted here这解决了同样的问题。还有post here可能有帮助。

使用ajax调用Webinvoke POST POST JSON
