Error when sending email using postal MVC?
Requirement:
Send emails to all users dynamically everyday at a particular time, say 6:00 AM.
What I did so far:
I use a third party library called Quartz.net from Nuget.
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 = "[email protected]";
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();
}
I am using Postal in MVC to send the email.
This works fine in my local if I run from my Visual Studio. But once I deploy it onto IIS, I get the error below:
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()
-------------
I am hosting this application as a sub directory in the IIS. So it is something like http://www.maindemosite.com/xyz

Solution
According to this issue: Postal Issue #65, it seems that you have HttpContext.Current contains null value when trying to get relative path of your project root directory in IIS deployment server. Here was the checklist to do:
Try moving
JobScheduler.Start()method fromApplication_StarttoApplication_AuthenticateRequestmethod call during application startup. AFAIK, theApplication_Startmethod doesn't containHttpContext.Currentinstance asApplication_AuthenticateRequesthas.protected void Application_AuthenticateRequest() { JobScheduler.Start(); }Check if your IIS deployment server setting set to integrated mode. In this mode Application_Start doesn't contain
HttpContext.Currentdue to design changes on integrated pipeline. As Mike Volodarsky said:
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).
The first choice means it was some alternatives beside Application_AuthenticateRequest, which uses Application_BeginRequest or any other event methods that includes HttpContext.Current instance.
If absolute path was used, check if it is exist on deployment server. The relative path is more preferred in web.config file, thus you may change paths like this:
<add key="DocumentsPath" value="~/Documents/Documents/" />
Afterwards, ensure Application_Start method doesn't contain any other method that contains HttpContext.Current instance, including database context if any.
