Question

我正在开发一个Asp.net Web应用程序。在我的应用程序中，我正在设置用户电子邮件确认和密码重置功能。我正在使用内置身份系统的Asp.net。根据Visual Studio中提到的链接 - https://www.asp.net/identity/overview/features-api/account-confirmation-and-password-recovery-with-aspnet-identity，可以启用这些功能。

但要遵循它，此链接已被破坏 - https://azure.microsoft.com/en-us/gallery/store/sendgrid/sendgrid-azure/。但没关系，我只想知道asp.net身份系统中的一件事。那是发送电子邮件。根据Visual Studio中的注释行，我可以发送如下所示的重置密码电子邮件。

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

该行简单易读。但问题是我在哪里可以配置发件人电子邮件凭据？它用于发送电子邮件的设置是什么？如何更改发件人电子邮件？我也无法关注该链接，因为Azure链接已损坏。我在哪里可以设置和更改这些设置？

我尝试在web.config中添加此设置

<system.net>
    <mailSettings>
      <smtp from="testing@gmai.com">
        <network host="smtp.gmail.com" password="testing" port="587" userName="testing"  enableSsl="true"/>
      </smtp>
    </mailSettings>
  </system.net>

但现在发送电子邮件。

Answer 1

最后我找到了解决方案。

我在web.config中添加了电子邮件设置，如此

<system.net>
    <mailSettings>
      <smtp from="testing@gmai.com">
        <network host="smtp.gmail.com" password="testing" port="587" userName="testing"  enableSsl="true"/>
      </smtp>
    </mailSettings>
  </system.net>

然后我更新了

public class EmailService : IIdentityMessageService
    {
        public Task SendAsync(IdentityMessage message)
        {
            // Plug in your email service here to send an email.

            return Task.FromResult(0);
        }
    }

在App_Start文件夹中的IdentityConfig.cs中到此

public class EmailService : IIdentityMessageService
    {
        public Task SendAsync(IdentityMessage message)
        {
            // Plug in your email service here to send an email.
            SmtpClient client = new SmtpClient();
            return client.SendMailAsync("email from web.config here",
                                        message.Destination,
                                        message.Subject,
                                        message.Body);

        }
    }

当我发送电子邮件时，它会自动使用web.config中的设置。

Public Sub RepositionForm(f As Object, c As Object)
    Dim P As POINTAPI
    Dim meHwnd As Long, hwnd As Long

    meHwnd = FindWindow(vbNullString, Me.Caption)

    P.x = (c.Left - (f.Width / 4)) / PointsPerPixelX
    P.y = (c.Top + c.Height) / PointsPerPixelY

    '~~> The ClientToScreen function converts the client coordinates

    '~~> Move the form to relevant location
    SetWindowPos hwnd, HWND_TOP, P.x, P.y, 0, 0, SWP_NOSIZE
End Sub

Private Function PointsPerPixelX() As Double
    Dim hDC As Long
    hDC = GetDC(0)
    PointsPerPixelX = 72 / GetDeviceCaps(hDC, LOGPIXELSX)
    ReleaseDC 0, hDC
End Function

Public Function PointsPerPixelY() As Double
    Dim hDC As Long
    hDC = GetDC(0)
    PointsPerPixelY = 72 / GetDeviceCaps(hDC, LOGPIXELSY)
    ReleaseDC 0, hDC
End Function

web.config

public class EmailService : IIdentityMessageService
{
    public Task SendAsync(IdentityMessage message)
    {
        //SmtpClient client = new SmtpClient();
        //return client.SendMailAsync("email from web.config here",
        //                            message.Destination,
        //                            message.Subject,
        //                            message.Body);

        var smtp = new SmtpClient();
        var mail = new MailMessage();
        var smtpSection = (SmtpSection)ConfigurationManager.GetSection("system.net/mailSettings/smtp");
        string username = smtpSection.Network.UserName;

        mail.IsBodyHtml = true;
        mail.From = new MailAddress(username);
        mail.To.Add(message.Destination);
        mail.Subject = message.Subject;
        mail.Body = message.Body;

        smtp.Timeout = 1000;

        var t = Task.Run(() => smtp.SendAsync(mail, null));

        return t;
    }
}
