使用邮政 MVC 发送电子邮件时出错？
Error when sending email using postal MVC?
要求：
每天在特定时间动态地向所有用户发送电子邮件，比如 6:00 AM。
到目前为止我做了什么：
我使用来自 Nuget 的名为 Quartz.net 的第三方库。
public class TaskScheduler : IJob
{
public void Execute(IJobExecutionContext context)
{
try {
UserRepository userRepo = new UserRepository();
var users = userRepo.GetUsers();
DashBoardRepository repo = new DashBoardRepository();
foreach (var rec in users)
{
var tasks = repo.GetIncompleteTasks(rec.UserID);
var appointments = repo.GetUpcomingAppointments(rec.UserID);
if (tasks.Count > 0 || appointments.Count > 0)
{
dynamic email = new Email("TaskEmail");
email.To = rec.Email;
email.From = "no-reply@xyz.com";
email.Subject = "Pending items in XYZ";
email.Tasks = tasks;
email.Appointments = appointments;
email.Send();
}
}
}
catch(Exception ex)
{
clsLog.LogMessageToFile(ex.ToString());
}
}
}
public static class JobScheduler
{
public static void Start()
{
IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler();
scheduler.Start();
IJobDetail job = JobBuilder.Create<TaskScheduler>().Build();
ITrigger trigger = TriggerBuilder.Create()
.WithDailyTimeIntervalSchedule
(s =>
s.WithIntervalInHours(24)
.OnEveryDay()
.StartingDailyAt(TimeOfDay.HourAndMinuteOfDay(6, 0))
)
.Build();
scheduler.ScheduleJob(job, trigger);
}
}
protected void Application_Start()
{
JobScheduler.Start();
}
我在 MVC 中使用邮政发送电子邮件。
如果我从我的 Visual Studio 运行 这在我的本地工作正常。但是一旦我将它部署到 IIS 上，我就会收到以下错误：
System.ArgumentException: The virtual path '/' maps to another application, which is not allowed.
at System.Web.CachedPathData.GetVirtualPathData(VirtualPath virtualPath, Boolean permitPathsOutsideApp)
at System.Web.HttpContext.GetFilePathData()
-------------
我将此应用程序托管为 IIS 中的子目录。所以它类似于 http://www.maindemosite.com/xyz

根据这个问题：Postal Issue #65，当您尝试在 IIS 部署服务器中获取项目根目录的相对路径时，似乎 HttpContext.Current 包含空值。这是要做的清单：
尝试在应用程序启动期间将 JobScheduler.Start() 方法从 Application_Start 移动到 Application_AuthenticateRequest 方法调用。据我所知，Application_Start 方法不包含 HttpContext.Current 实例，因为 Application_AuthenticateRequest 有。
protected void Application_AuthenticateRequest()
{
JobScheduler.Start();
}
检查您的 IIS 部署服务器设置是否设置为集成模式。由于集成管道的设计更改，在此模式下 Application_Start 不包含 HttpContext.Current。正如 Mike Volodarsky 所说：
Basically, if you happen to be accessing the request context in
Application_Start, you have two choices:
- Change your application code to not use the request context (recommended).
- Move the application to Classic mode (NOT recommended).
第一个选择意味着它是 Application_AuthenticateRequest 之外的一些替代方案，它使用 Application_BeginRequest 或任何其他包含 HttpContext.Current 实例的事件方法。
如果使用了绝对路径，请检查它是否存在于部署服务器上。 web.config 文件中的相对路径更受欢迎，因此您可以这样更改路径：
<add key="DocumentsPath" value="~/Documents/Documents/" />
之后，确保 Application_Start 方法不包含任何其他包含 HttpContext.Current 实例的方法，包括数据库上下文（如果有的话）。
