.Net Core 配置Nlog

.Net Core 配置Nlog   (在控制器中配置)

1. 在nuget 包当中添加 Nlog.Web.AspNetCore   4.9+包(必须4.9+最新的)（在控制器层）

2. 在控制器层创建一个nlog.config （全部小写）文件

3. 
4. 将以下代码复制到nlog.config 当中

   <?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"
         autoReload="true"
         internalLogLevel="Info"
         internalLogFile="c:\temp\internal-nlog-AspNetCore.txt">
   
     <!-- enable asp.net core layout renderers -->
     <extensions>
       <add assembly="NLog.Web.AspNetCore"/>
     </extensions>
   
     <!-- the targets to write to -->
     <targets>
       <!-- File Target for all log messages with basic details -->
       <target xsi:type="File" name="allfile" fileName="c:\temp\nlog-AspNetCore-all-${shortdate}.log"
               layout="${longdate}|${event-properties:item=EventId_Id:whenEmpty=0}|${level:uppercase=true}|${logger}|${message} ${exception:format=tostring}" />
   
       <!-- File Target for own log messages with extra web details using some ASP.NET core renderers -->
       <target xsi:type="File" name="ownFile-web" fileName="c:\temp\nlog-AspNetCore-own-${shortdate}.log"
               layout="${longdate}|${event-properties:item=EventId_Id:whenEmpty=0}|${level:uppercase=true}|${logger}|${message} ${exception:format=tostring}|url: ${aspnet-request-url}|action: ${aspnet-mvc-action}|${callsite}" />
   
       <!--Console Target for hosting lifetime messages to improve Docker / Visual Studio startup detection -->
       <target xsi:type="Console" name="lifetimeConsole" layout="${MicrosoftConsoleLayout}" />
     </targets>
   
     <!-- rules to map from logger name to target -->
     <rules>
       <!--All logs, including from Microsoft-->
       <logger name="*" minlevel="Trace" writeTo="allfile" />
   
       <!--Output hosting lifetime messages to console target for faster startup detection -->
       <logger name="Microsoft.Hosting.Lifetime" minlevel="Info" writeTo="lifetimeConsole, ownFile-web" final="true" />
   
       <!--Skip non-critical Microsoft logs and so log only own logs (BlackHole) -->
       <logger name="Microsoft.*" maxlevel="Info" final="true" />
       <logger name="System.Net.Http.*" maxlevel="Info" final="true" />
   
       <logger name="*" minlevel="Trace" writeTo="ownFile-web" />
     </rules>
   </nlog>　

 

　　　5.修改 program.cs 文件，代码如下   共2步

　　　　

 

配置完成   输出Nlog
