标签： c# asp.net-mvc-5 log4net

我尝试使用此配置：

<log4net>
    <appender name="SmtpAppender" type="log4net.Appender.SmtpAppender,log4net">
        <to value="myaccount@supinfo.com" />
        <from value="support@company.com" />
        <subject value="TimeZone Crash log" />
        <smtpHost value="in.mailjet.com" />
        <username value="login" />
        <password value="password" />
        <bufferSize value="10" />
        <lossy value="false" />
        <evaluator type="log4net.Core.LevelEvaluator,log4net">
            <threshold value="WARN" />
        </evaluator>
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%level %date - %message%newline" />
        </layout>
    </appender>
    <logger name="SmtpAppender">
        <level value="ERROR" />
        <appender-ref ref="SmtpAppender" />
    </logger>
    <appender name="Trace" type="log4net.Appender.RollingFileAppender">
        <file value="c:\Traces\TimeZone.log" />
        <PreserveLogFileNameExtension value="true" />
        <appendToFile value="true" />
        <maximumFileSize value="10MB" />
        <maxSizeRollBackups value="2" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%level %date - %message%newline" />
        </layout>
        <param name="Encoding" value="utf-8" />
    </appender>
    <logger name="Trace">
        <!--ALL
        DEBUG
        INFO
        WARN
        ERROR
        FATAL
        OFF-->
        <level value="DEBUG" />
        <appender-ref ref="Trace" />
    </logger>
</log4net>

我有这个内部日志

我在TimeZone.log文件中找到了日志但没有邮件！ 请注意，我登录了错误＆amp;我可以通过代码发送电子邮件。我有这个配置：

<system.net>
    <mailSettings>
        <smtp deliveryMethod="network">
            <network defaultCredentials="false" host="in.mailjet.com" userName="login" password="password" enableSsl="true"/>
        </smtp>
    </mailSettings>
</system.net>

我不知道我做错了什么！

将此问题用于我自己的故障排除，我想分享我的发现。

当我使用端口465时，没有发送电子邮件，尽管它可以被服务器接受。简单的解决方案是使用：

<port value="587" />

对于有兴趣使用除gmail之外的人，以下是雅虎邮件的完整设置：

 <configuration>
  <configSections>
    <section name ="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
  </configSections>
  <log4net>
    <appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
      <to value="email1@gmail.com; email2@yahoo.com" />
      <from value="your_User_Name@yahoo.co.uk" />
      <subject type="log4net.Util.PatternString" value="Message logged" />
      <smtpHost value="smtp.mail.yahoo.com" />
      <authentication value="Basic" />
      <port value="587" />
      <username value="your_User_Name@yahoo.co.uk" />
      <password value="your_password" />
      <bufferSize value="1" />
      <EnableSsl value="true"/>
      <lossy value="false" />
      <threshold value="DEBUG" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%utcdate [%level] - %message%newline%exception" />
      </layout>
    </appender>
    <root>
      <level value="DEBUG"/>
      <appender-ref ref="SmtpAppender"/>
    </root>
  </log4net>
</configuration>

Log4net无提示失败，因此您不会看到任何错误。对于调试，请在app.config / web.config文件中添加以下内容。任何错误都会记录在那里。

 <appSettings>
    <add key="log4net.Internal.Debug" value="true" />
 </appSettings>

 <system.diagnostics>
  <trace autoflush="true">
   <listeners>
    <add name="tracer" 
     type="System.Diagnostics.TextWriterTraceListener"
     initializeData="C:\\yourfolder\\log4net.log" />
    </listeners>
   </trace>
 </system.diagnostics>

我的配置无法解决，它与我使用的配置类似。试试这些测试：

更改

<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender,log4net">

到

<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">

更改

    <bufferSize value="10" />

到

    <bufferSize value="1" />

这样可以防止缓冲，以便立即发送电子邮件。

尝试删除以下内容，以便通过电子邮件发送所有内容：

    <evaluator type="log4net.Core.LevelEvaluator,log4net">
        <threshold value="WARN" />
    </evaluator>

我使用gmail解决了我的问题。 我尝试使用mailjet使用相同的配置（端口，主机等除外），但它没有用。

我现在的配置：

<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
  <to value="to@mail.com" />
  <from value="from@mail.com" />
  <subject value="Crash log" />
  <smtpHost value="smtp.gmail.com" />
  <authentication value="Basic" />
  <port value="587" />
  <username value="myusername" />
  <password value="mypassword" />
  <bufferSize value="1" />
  <EnableSsl value="true"/>
  <lossy value="true" />
  <evaluator type="log4net.Core.LevelEvaluator">
    <threshold value="ERROR"/>
  </evaluator>
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%level %date - %message%newline" />
  </layout>
</appender>

配置已指定用户名和密码，但未指定身份验证。 添加以下身份验证元素，意味着您的配置将在连接时使用用户名和密码。

<authentication value="Basic" />
