首先是引包

NLog.Web.AspNetCore

添加配置文件 nlog.config

<?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" internalLogLevel="Info">
  <!-- 启用.net core的核心布局渲染器 -->
  <extensions>
    <add assembly="NLog.Web.AspNetCore" />
  </extensions>
  <!-- 写入日志的目标配置 -->
  <targets>
    <!-- 调试  -->
    <target xsi:type="File" name="debug" fileName="logs/debug-${shortdate}.log" layout="${longdate}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}|url: ${aspnet-request-url}|action: ${aspnet-mvc-action}" />
    <!-- 警告  -->
    <target xsi:type="File" name="warn" fileName="logs/warn-${shortdate}.log" layout="[${uppercase:${level}}] ${longdate}  ${logger} action: ${aspnet-mvc-action} CustomMsg:${message}  Exception:${exception:format=tostring}  url: ${aspnet-request-url}" />
    <!-- 错误  -->
    <target xsi:type="File" name="error" fileName="logs/error-${shortdate}.log" layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}|url: ${aspnet-request-url}|action: ${aspnet-mvc-action}" />
  </targets>
  <!-- 映射规则 -->
  <rules>
    <!-- 调试  -->
    <logger name="*" minlevel="Trace" maxlevel="Debug" writeTo="debug" />
    <!--跳过不重要的微软日志-->
    <logger name="Microsoft.*" maxlevel="Info" final="true" />
    <!-- 警告  -->
    <logger name="*" minlevel="Info" maxlevel="Warn" writeTo="warn" />
    <!-- 错误  -->
    <logger name="*" minlevel="Error" maxlevel="Fatal" writeTo="error" />
  </rules>
</nlog>

最后在program里启用NLog
