我试图从我的数据库中获取事件，但我无法让它工作。该事件不显示在我的日历，在我的Web控制台，我得到：完整日历GetEvents（）方法调用不工作
无法加载资源：服务器500（内部服务器错误）的状态
抛出异常回应：
参数字典包含'ForecastCalendar.Controllers'中方法'System.Web.Mvc.JsonResult GetEvents（Double，Double）'的非空类型'System.Double'的参数'start'的空项。 HomeController的”。可选参数必须是引用类型，可为空类型，或者声明为可选参数。 参数名：参数
这里是我的控制，我用它来获取事件的方法：
public JsonResult GetEvents(double start, double end)
{
var events = new List<Event>();
var dtstart = ConvertFromUnixTimestamp(start);
var dtend = ConvertFromUnixTimestamp(end);
DateTime currStart;
DateTime currEnd;
foreach (Event ev in db.Events)
{
currStart = Convert.ToDateTime(ev.StartDate);
currEnd = Convert.ToDateTime(ev.EndDate);
events.Add(new Event()
{
ID = ev.ID,
Title = ev.Title,
StartDate = currStart,
EndDate = currEnd,
AllDay = true,
EventType = ev.EventType,
Hours = ev.Hours
});
}
var rows = events.ToArray();
return Json(rows, JsonRequestBehavior.AllowGet);
}
private static DateTime ConvertFromUnixTimestamp(double timestamp)
{
var origin = new DateTime(1970, 1, 1, 0, 0, 0, 0);
return origin.AddSeconds(timestamp);
}
下面是我的事件模型：
using System;
using System.ComponentModel.DataAnnotations;
namespace ForecastCalendar.Models
{
public enum EventType
{
BAU,
Project,
AnnualLeave
}
public class Event
{
public int ID { get; set; }
[Required]
[DataType(DataType.Date, ErrorMessage = "Please enter a valid date.")]
[DisplayFormat(DataFormatString = "{0:dd-MM-yyyy}", ApplyFormatInEditMode = true)]
[Display(Name = "Start Date")]
public DateTime StartDate { get; set; }
[Required]
[DataType(DataType.Date, ErrorMessage = "Please enter a valid date.")]
[DisplayFormat(DataFormatString = "{0:dd-MM-yyyy}", ApplyFormatInEditMode = true)]
[Display(Name = "End Date")]
public DateTime EndDate { get; set; }
[Required]
[StringLength(50, ErrorMessage = "Title cannot be longer than 50 characters.")]
[RegularExpression(@"^[a-zA-Z- ]+$", ErrorMessage = "Invalid characters used. A-Z or a-z, '-' and ' ' allowed.")]
[Display(Name = "Title")]
public string Title { get; set; }
[Required]
[EnumDataType(typeof(EventType), ErrorMessage = "Submitted value is not valid.")]
[Display(Name = "Type")]
public EventType? EventType { get; set; }
[Required]
public double Hours { get; set; }
[Required]
public Boolean AllDay { get; set; }
[Timestamp]
public byte[] RowVersion { get; set; }
public virtual Person Person { get; set; }
}
}
这里是JavaScript，其中日历已呈现。
@{
ViewBag.Title = "Home Page";
}
@Styles.Render("~/Content/fullcalendar")
@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/fullcalendar")
<br />
<div class="container">
<div id="calendar"></div>
</div>
<br />
<script type="text/javascript">
$(document).ready(function() {
$('#calendar').fullCalendar({
header: {
left: 'title',
center: '',
right: 'prev,next today' },
defaultView: 'month',
weekends: false,
editable: false,
events: "/Home/GetEvents/"
});
});
</script>
任何帮助，非常感谢。
编辑：
我已经改变了我GetEvents（）方法，以符合全日历事件类型。
public JsonResult GetEvents(double start, double end)
{
var fromDate = ConvertFromUnixTimestamp(start);
var toDate = ConvertFromUnixTimestamp(end);
var rslt = db.Events;
List<Event> result = new List<Event>();
foreach (var item in rslt)
{
Event ev = new Event();
ev.ID = item.ID;
ev.Title = item.Title;
ev.Hours = item.Hours;
ev.StartDate = item.StartDate;
ev.EndDate = item.EndDate;
ev.EventType = item.EventType;
ev.AllDay = ev.AllDay;
}
var resultList = result;
var eventList = from e in resultList
select new
{
id = e.ID,
title = e.Title,
start = e.StartDate,
end = e.EndDate,
allDay = e.AllDay
};
var rows = eventList.ToArray();
return Json(rows, JsonRequestBehavior.AllowGet);
}
那么抛出什么异常呢？ Http 500响应意味着服务器出现问题。 –
请提供完整的错误信息（它附带有错误回调），因为错误500通常意味着服务器端的东西被压坏。 – DonCziken
我已将例外添加到我的OP中。 – James
