c# - 如何为 Controller 创建我自己的 http 上下文？

Question

我正在使用 asp.net mvc 3 和 quartz 调度程序。

目前我有这个

1. 创建并执行作业。
2. 转到我映射域的 Controller 以使用自动映射器查看模型
3. 结果转到我要使用的 Controller Action Mailer

我得到一个错误

System.ArgumentNullException was unhandled by user code
  Message=Value cannot be null.
Parameter name: httpContext
  Source=System.Web
  ParamName=httpContext
  StackTrace:
       at System.Web.Routing.RequestContext..ctor(HttpContextBase httpContext, RouteData routeData)
       at ActionMailer.Net.MailerBase.Email(String viewName, Object model, String masterName)

  InnerException:

public void Execute(JobExecutionContext context)
        {


                            // some code to do some checking and to get results above(not shown)
                            RemindersController remindersController = new RemindersController();
                            remindersController.CalendarAppointmentsReminders(calendarAppointmentReminders);

            }

// Controller (做映射)\

   public void CalendarAppointmentsReminders(List<AppointmentReminder> appointments)
        {
           List<CalendarAppointmentReminderVM> vm = Mapper.Map<List<CalendarAppointment>, List<CalendarAppointmentReminderVM>>(appointments.Select(x => x.CalendarAppointment).ToList());
            Mapper.Map<List<AppointmentReminder>, List<CalendarAppointmentReminderVM>>(appointments, vm);


            foreach (var v in vm)
            {
                new EmailController().SendCalendarAppointmentNotifiation(v);
            }

        }

//mvc 邮件程序

 public EmailResult SendCalendarAppointmentNotifiation(CalendarAppointmentReminderVM vm)
        {
            To.Add(vm.To);
            Subject = String.Format("Subject");
            return Email("SendCalendarAppointmentEmail", vm);
        }

在 return Email("SendCalendarAppointmentEmail", vm); 上死去(更容易使它们看起来更好，因为您可以使用母版页和强类型 View )。

Answer 1

Quartz 的作业执行不在 HttpRequest 中运行。 HttpContext.Current 也为 NULL。如果没有 asp.net 请求环境，这个 asp.net 邮件程序似乎无法工作(看看 StackTrace)

结帐Render a view as a string (呈现 View 、放入邮件并发送..)，但不幸的是，在这篇文章中，所有示例也适用于当前的 ControllerContext/HttpContext。
