使用 NLog 时保护电子邮件密码

Question

当使用 NLog 作为日志工具时，我们可以轻松地通过电子邮件发送消息，例如，这是使用 Gmail 作为 smtp 服务器的示例配置：

<targets>
<target name="gmail" type="Mail"
        smtpServer="smtp.gmail.com"
        smtpPort="587"
        smtpAuthentication="Basic"
        smtpUsername="[email protected]"
        smtpPassword="password"
        enableSsl="true"
        from="[email protected]"
        to="[email protected]"
        cc="[email protected];[email protected];[email protected]"
      />
</targets>
<rules>
 <logger name="*" minlevel="Debug" writeTo="gmail" />
</rules>

它就像一个魅力。 但在上面的示例中，密码以纯文本形式放入配置文件中。
有办法以某种方式保护它吗？

Answer 1

是的，您可以将 NLog.config（如果此文件中有）移至您的 app.config，然后加密您的 app.config。

您可以查看如何加密 app.config 此处。

Answer 2

您可以在代码中配置记录器。在那里，您甚至可以向任何拥有十六进制编辑器的人隐藏您的密码！另外，没有人有机会弄乱您的配置文件。

Public Class MyEmailLoggerClass
    Public Sub New()
        SetNlogConfiguration()
    End Sub

    Private Sub SetNlogConfiguration()
        Private MyNLogConfiguration As New LoggingConfiguration()
        Dim myemailtarget As New MailTarget()
        Dim MailRule As New LoggingRule("myemail", LogLevel.Info, myemailtarget) 

        With myemailtarget
            .SmtpServer = "mail.724hosting.com"
            .SmtpAuthentication = SmtpAuthenticationMode.Basic
            .SmtpUserName = "myemail" & "@" & "somewhere.com"
            .SmtpPassword = "my" & "pass" & "word"
            .SmtpPort = 587
            '.Encoding = System.Text.Encoding.UTF8
            .EnableSsl = true
            .AddNewLines = True
            .Html = True
            .Layout = "${message}"
            'message options
            .To = "sometech" & "@" & "somewhere.com"
            .cc = "[email protected],[email protected]"
            .From = "[email protected]"
            .Header = "<h2 style='color:red'>Message from myapplication!</h2>"
            .Subject = "Report from " & myapplicationname & " on someone's computer" & ${date:F}"
            .Body = "${message}"
        End With

        LogManager.Configuration = myNlogConfig
    End Sub
End Class

要使用它，请将其放在您要发送电子邮件的子目录中：

    Public MainLogger As New MyEmailLoggerClass
    Dim Logger = LogManager.GetLogger("myemail")
    Logger.Info("Hi, this is a message from my application")
