异步电子邮件发送不返回视图

本文关键字：返回 视图 电子邮件 异步 | 更新日期: 2023-09-27 18:30:56

我的 Asp.net 网站上的忘记密码电子邮件链接有问题。

基本上，一切正常，它会向帐户发送电子邮件，密码可以重置，但我收到 404 错误而不是返回正确的页面。

public async Task<ActionResult> ForgotPassword(ForgotPasswordViewModel model)
{
    if (ModelState.IsValid)
    {
        var user = await UserManager.FindByEmailAsync(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");
        }
        // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
        // Send an email with this link
        string code = await UserManager.GeneratePasswordResetTokenAsync(user.Id);
        var callbackUrl = Url.Action("ResetPassword", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
        await UserManager.SendEmailAsync(user.Id, "Reset Password", "Please reset your password by clicking <a href='"" + callbackUrl + "'">here</a>");
        return RedirectToAction("ForgotPasswordConfirmation", "Account");
    }
    // If we got this far, something failed, redisplay form
    return View(model);
}

我认为这是这条线的问题：

await UserManager.SendEmailAsync(user.Id, "Reset Password", "Please reset your password by clicking <a href='"" + callbackUrl + "'">here</a>");

如果没有此行，它将返回正确的视图，但显然电子邮件不会发送。我已经调试并逐步完成它，但找不到任何错误。

还有其他人遇到过这种情况吗？

提前致谢

注意：如果模型为空，则返回正确的视图

编辑：标识消息

public Task SendAsync(IdentityMessage message)
{
    // Plug in your email service here to send an email.
    var mailMessage = new MailMessage("Email here",
        message.Destination,
        message.Subject,
        message.Body
        );
    var client = new SmtpClient();
    client.SendAsync(mailMessage, null);
    return Task.FromResult(0);
}

异步电子邮件发送不返回视图

在电子邮件部分中，您应该会收到此错误"异步模块或处理程序已完成，而异步操作仍处于挂起状态"。我相信你得到404是因为可能没有找到错误页面。

您可以尝试以下操作

public Task SendAsync(IdentityMessage message)
    {
        // Plug in your email service here to send an email.
        var mailMessage = new MailMessage("Email here",
            message.Destination,
            message.Subject,
            message.Body
            );
        var client = new SmtpClient();
        return client.SendMailAsync(mailMessage);
    }

或使用等待/异步方式

public async Task SendAsync(IdentityMessage message)
        {
            // Plug in your email service here to send an email.
            var mailMessage = new MailMessage("Email here",
                message.Destination,
                message.Subject,
                message.Body
                );
            var client = new SmtpClient();
            await client.SendMailAsync(mailMessage);
        }
