Question

是否可以安装nlog并为多个项目登录？目前，我已使用以下配置文件将其安装在班级库中：

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd"
      autoReload="true"
      throwExceptions="false"
      internalLogLevel="Off" internalLogFile="c:\temp\nlog-internal.log">

  <!-- optional, add some variables
  https://github.com/nlog/NLog/wiki/Configuration-file#variables
  -->
  <variable name="myvar" value="myvalue"/>

  <!--
  See https://github.com/nlog/nlog/wiki/Configuration-file
  for information on customizing logging rules and outputs.
   -->
  <targets>

    <target xsi:type="Database"
            name="database"
            connectionStringName="DefaultConnection"
            commandText="INSERT INTO [dbo].[AspNetEventLogs] ([Application], [Logged], [Level],[Message],[UserName],[ServerName],[Port],[Url],[Https],[ServerAddress],[Logger],[Callsite], [Exception]) VALUES (@Application, @Logged, @Level, @Message, @UserName, @ServerName, @Port, @Url, @Https, @ServerAddress, @Logger, @CallSite,  @Exception);
            ">

      <parameter name="@application" layout="${appsetting:name=appName}" />
      <parameter name="@logged" layout="${date}" />
      <parameter name="@level" layout="${level}" />
      <parameter name="@message" layout="${message}" />
      <parameter name="@username" layout="${identity}" />
      <parameter name="@serverName" layout="${aspnet-request:serverVariable=SERVER_NAME}" />
      <parameter name="@port" layout="${aspnet-request:serverVariable=SERVER_PORT}" />
      <parameter name="@url" layout="${aspnet-request:serverVariable=HTTP_URL}" />
      <parameter name="@https" layout="${when:inner=1:when='${aspnet-request:serverVariable=HTTPS}' == 'on'}${when:inner=0:when='${aspnet-request:serverVariable=HTTPS}' != 'on'}" />
      <parameter name="@serverAddress" layout="${aspnet-request:serverVariable=LOCAL_ADDR}" />
      <parameter name="@logger" layout="${logger}" />
      <parameter name="@callSite" layout="${callsite}" />
      <parameter name="@exception" layout="${exception:tostring}" />
    </target>

  </targets>

  <rules>
    <!-- add your logging rules here -->
    <logger name="*" minlevel="Trace" writeTo="database" />
    <!--
    Write all events with minimal level of Debug (So Debug, Info, Warn, Error and Fatal, but not Trace)  to "f"
    <logger name="*" minlevel="Debug" writeTo="f" />
    -->
  </rules>
</nlog>

但是，当前其中某些列未正确填充。服务器名称为空，应用程序名称为空。我希望在同一解决方案中将其用于多个项目。

如果将nlog.config部署在正确的文件夹中并且其他项目可以访问“ httpcontext”（例如其他ASP.NET项目），则Tt应该可以工作

关于空值，请检查内部日志：https://github.com/nlog/NLog/wiki/Internal-logging

请注意，${aspnet-request}需要NLog.Web或NLog.Web.AspNetCore

ASP.NET MVC使用NLog记录多个项目
