an email is causing errors

Question

One of our business partners provided an email for her client to send out to prospective employees that missed a space between the URL and the instructions, and now is throwing errors in my MVC application which then sends me notification of the error. The email says

Click the link https://beta.commonwealthhotelsassessments.com/or cut/paste (-> https://beta.commonwealthhotelsassessments.com/or%2520cut/paste) this website address into the address bar, and then choose Click Here for New User Registration. Fill in the required information to Register to Take an Assessment. Then click the Register button.”

basically the error messages I am getting say

The controller for path '/or cut/paste' was not found or does not implement IController.

I have asked our business partner to correct the email template and send to Commonwealth Hotels (her client) but they are still sending the bad emails out. Is there something I can do on the site to redirect the user when this occurs so that they are taken right to the home page?

Answer 1

my error reporting model looks like this

using System;
using System.Diagnostics;
using System.Web;
using MailKit.Net.Smtp;
using MimeKit;

namespace Commonwealth.Models
{
    public class Errors
    {
        public static void ErrorOccured(Exception ex)
        {
            var st = new StackTrace(ex, true);
            // Get the top stack frame
            var frame = st.GetFrame(0);
            // Get the line number from the stack frame
            var line = frame.GetFileLineNumber();
            string page = frame.GetFileName();
            var col = frame.GetFileColumnNumber();

            string domain = HttpContext.Current.Request.Url.Host;
            string MailBody = ex.Message.ToString() + "\r\n
            string MessageToSend = ex.StackTrace.ToString();
            string MailSender = "website email";
            string MailRecipient = "my email";
            string MailSubject = "Error on " + domain;
            MimeMessage msg = new MimeMessage();

            msg.From.Add(new MailboxAddress("", MailSender));
            msg.To.Add(new MailboxAddress("",MailRecipient));
            msg.Subject = MailSubject;
            msg.Body = new TextPart(MimeKit.Text.TextFormat.Html) { Text = MailBody + "\r\n
            using (var smtp = new SmtpClient())
            {
                smtp.Connect("emailserver", 587, false);
                smtp.Authenticate("emailuser", "password");
                smtp.Send(msg);
                smtp.Disconnect(true);
            }
        }
    }
}

and then the controller has this

public ActionResult About()
        {
            try
            {
                return View();
            }
            catch (Exception ex)
            {
                Errors.ErrorOccured(ex);
            }
            return RedirectToAction("Index", "Error", null);
        }

Answer 2

You can use iis url rewrite to fix the url. Or make it a valid route, typically with attribute routing.

Hi @M J

Please try the overloading method

public ActionResult About()
        {
            
                return View();
            
        }
[HttpPost]
public ActionResult About()
        {
            try
            {
                return View();
            }
            catch (Exception ex)
            {
                Errors.ErrorOccured(ex);
                return RedirectToAction("Index", "Error", null);
            }
            
        }

Best Regards
