上代码

step 1 添加nuget

添加nuget 包 Roc

step 2 添加支持

修改program.cs

var builder = WebApplication.CreateBuilder(args);
// 添加NLog日志支持
builder.AddRocNLog();

step 3 添加配置文件

添加配置文件 位置 看图， （注意位置和大小写）

<?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"
      autoReload="true"
      throwExceptions="true"
      internalLogLevel="Error"
      internalLogFile="nlogs/nlog-internal.log"
>
  <extensions>
    <add assembly="NLog.Web.AspNetCore"/>
  </extensions>

  <!--<variable name="directory" value="${basedir}/logs"/>-->
  <variable name="directory" value="/home/logs/Roc"/>

  <targets async="true">
    <!-- Console -->
    <target name="Console"
            xsi:type="ColoredConsole"
            encoding="utf-8"
            layout="${longdate} [${level:uppercase=true}] ${logger} : ${message} ${exception:format=tostring}"
    />

    <!-- Info -->
    <target name="Info"
            xsi:type="File"
            encoding="utf-8"
            maxArchiveDays="7"
            archiveAboveSize="20971520"
            archiveEvery="Day"
            fileName="${directory}/log/${date:format=yyyy-MM-dd}.log"
            layout="${longdate} [${level}] [${callsite-linenumber}] ${callsite} : ${message}"
    />

    <!-- Error -->
    <target name="Error"
            xsi:type="File"
            encoding="utf-8"
            maxArchiveDays="7"
            archiveAboveSize="20971520"
            archiveEvery="Day"
            fileName="${directory}/bug/${date:format=yyyy-MM-dd}.log"
            layout="${longdate} [${level}] [${callsite-linenumber}] ${callsite} : ${message} ${exception:format=tostring}"
    />
  </targets>

  <rules>
    <logger name="*" minlevel="Info" writeTo="Console"/>
    <logger name="*" maxlevel="Info"  writeTo="Info"/>
    <logger name="*" minlevel="Error"  writeTo="Error"/>
  </rules>
</nlog>
