用户无法恢复其密码asp.net mvc5

Question

As the title says my users can't recover their password if they lose it. For some reason it doesn't send the email. I have it working when they are going to confirm their email address than they do receives an email.

Here is the code for that:

    if (ModelState.IsValid)
{
    var user = new ApplicationUser() { UserName = model.Username };
    user.Email = model.Email;
    user.EmailConfirmed = false;
    var result = await UserManager.CreateAsync(user, model.Password);
    if (result.Succeeded)
    {
        MailMessage m = new MailMessage(
            new MailAddress("noreply@stuff.net", "Web Registration"),
            new MailAddress(user.Email));
        m.Subject = "Email confirmation";
        m.Body = string.Format("Dear {0}<BR/>Thank you for your registration, please click on the below link to complete your registration: <a href=\"{1}\" title=\"User Email Confirm\">{1}</a>", user.UserName, Url.Action("ConfirmEmail", "Account", new { Token = user.Id, Email = user.Email }, Request.Url.Scheme));
        m.IsBodyHtml = true;
        SmtpClient smtp = new SmtpClient("mail.stuff.net");
        smtp.Credentials = new NetworkCredential("noreply@stuff.net", "passwordstuff");
        smtp.EnableSsl = false;
        smtp.Port = 8889;
        smtp.Send(m);
        return RedirectToAction("ConfirmEmail", "Account", new { Email = user.Email });
    }
    else
    {
        AddErrors(result);
    }
}

And here is the code for when they want to recover their password:

            if (ModelState.IsValid)
        {
            var user = await UserManager.FindByNameAsync(model.Email);
            if (user == null || !(await UserManager.IsEmailConfirmedAsync(user.Id)))
            {
                // Don't reveal that the user does not exist or is not confirmed
                return View("ForgotPasswordConfirmation");
            }

            string code = await UserManager.GeneratePasswordResetTokenAsync(user.Id);

            MailMessage m = new MailMessage(
            new MailAddress("noreply@stuff.net", "Web Registration"),
            new MailAddress(user.Email));
            m.Subject = "Forgotten Password";
            m.Body = string.Format("Dear {0}<BR/>Please click on the below link to reset your password: <a href=\"{1}\" title=\"User Forgotten Password\">{1}</a>", user.UserName, Url.Action("ResetPassword", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme));
            m.IsBodyHtml = true;
            SmtpClient smtp = new SmtpClient("mail.stuff.net");
            smtp.Credentials = new NetworkCredential("noreply@stuff.net", "stuff");
            smtp.EnableSsl = false;
            smtp.Port = 8889;
            smtp.Send(m);
            return RedirectToAction("ForgotPasswordConfirmation", "Account");
        }

But for some reason this doesn't work, and they won't get an email on how to reset their password.

Answer 1

Assuming that you are using MVC's out-of-the-box template, then:

var user = await UserManager.FindByNameAsync(model.Email);

should really be:

var user = await UserManager.FindByEmailAsync(model.Email);

because the input box asks for email, not user name.

Then, unless you have set the site to require email confirmation, the line:

if (user == null || !(await UserManager.IsEmailConfirmedAsync(user.Id)))

should be

if (user == null)

This will at least get you to the codes that sends out the email. I just ran into the same issue today, and the above changes solved it for me.
