c# – 异步电子邮件发送未返回视图

2023年12月28日 104次阅读

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,它发送一个电子邮件到帐户,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);
}

我认为这是一个问题：

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

没有这一行,它会返回正确的视图,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.

有人遇到过这种情况么？

提前致谢

注：如果模型为null,则返回正确的视图

编辑：身份信息

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);
}

最佳答案 在电子邮件部分,您应该收到此错误“在异步操作仍处于挂起状态时完成异步模块或处理程序”.我相信你有404是因为可能没有找到错误页面.

您可以尝试以下方法

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);
    }

或者使用await / async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);
        }
