[英]log4net smtp appender not sending emails
I'm trying to implement log4net to send email. 我正在尝试实现log4net来发送电子邮件。
The following is my code but it's not sending emails. 以下是我的代码,但未发送电子邮件。
<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
<to value="...." />
<from value="..." />
<subject value="Logging Message" />
<smtpHost value="smtp.gmail.com" />
<port value="465"/>
<authentication value="Basic" />
<username value="..."/>
<password value="..."/>
<EnableSsl value="true" />
<bufferSize value="1" />
<lossy value="true" />
<evaluator type="log4net.Core.LevelEvaluator">
<threshold value="WARN"/>
</evaluator>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline%exception" />
</layout>
</appender>
and 和
<root>
<level value="WARN" />
<appender-ref ref="SmtpAppender" />
</root>
in the AssemblyInfo.cs 在AssemblyInfo.cs中
[assembly: log4net.Config.XmlConfiguratorAttribute(Watch = true)]
and that's how I create the log object 这就是我创建日志对象的方式
private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
This configuration is working fine for file output ie RollingFileAppender but not for SmtpAppender. 此配置对于文件输出(即RollingFileAppender)工作正常,但不适用于SmtpAppender。
N i have tried many solutions from the internet but were not really helpful. 我没有尝试过互联网上的许多解决方案,但并没有真正的帮助。
Please show me the right directions. 请告诉我正确的方向。 thankx in advance :) 提前感谢:)
I'm using a very similar appender for SMTP messages to Gmail, but in my case I use a different port: 我使用与Gmail SMTP邮件非常类似的附加程序,但在我的情况下,我使用了不同的端口:
<port value="587"/>
All the other settings are the same, so give that a try and see if it works for you. 所有其他设置都相同,因此请尝试一下,看看它是否对您有用。 It's the port Gmail uses for TLS, referenced here . 这是Gmail用于TLS的端口, 在此引用 。
For those running into issues with SmtpAppender I would recommend putting the following into your appSettings node. 对于那些遇到SmtpAppender问题的人,我建议将以下内容放入您的appSettings节点中。
<appSettings>
<add key="log4net.Internal.Debug" value="true"/>
</appSettings>
It will then output diagnostics such as this below to point you in the right direction 然后它将在下面输出诸如此类的诊断信息,以指示您正确的方向
