ASP.NET Core使用NLog输出日志记录

ASP.NET Core 中的日志记录

https://docs.microsoft.com/zh-cn/aspnet/core/fundamentals/logging/?view=aspnetcore-2.1

File="c:tempinternal-nlog.txt"> <!-- enable asp.net core layout renderers --> <extensions> <add assembly="NLog.Web.AspNetCore"/> </extensions> <!-- the targets to write to --> <targets> <!-- write logs to file --> <target xsi:type="File" name="allfile" fileName="c:tempnlog-all-${shortdate}.log" layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}" /> <!-- another file log, only own logs. Uses some ASP.NET core renderers --> <target xsi:type="File" name="ownFile-web" fileName="c:tempnlog-own-${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> <!-- rules to map from logger name to target --> <rules> <!--All logs, including from Microsoft--> <logger name="*" minlevel="Trace" writeTo="allfile" /> <!--Skip non-critical Microsoft logs and so log only own logs--> <logger name="Microsoft.*" maxLevel="Info" final="truuAcNcuwnCe" /> <!-- BlackHole without writeTo --> <logger name="*" minlevel="Trace" writeTo="ownFile-web" /> </rules></nlog>

复制到输出目录：始终复制

Update program.cs

这里 nlog-all-.log 是记录所有日志，nlog-own-.log 记录跳过Microsoft 开头的类库输出的相关信息，剩下的信息。
