1).添加nlog.config配置文件

?? <?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="Warn"

????? internalLogFile="internal-nlog.txt">

?

? <!-- Load the ASP.NET Core plugin -->

? <extensions>

??? <add assembly="NLog.Web.AspNetCore"/>

? </extensions>

?

? <!-- define various log targets -->

? <targets>

??? <!-- write logs to file -->

??? <target xsi:type="File" name="allfile" fileName="nlog-all-${shortdate}.log"

???????????????? layout="${longdate}|${logger}|${uppercase:${level}}|${message} ${exception}" />

?

?

??? <target xsi:type="File" name="ownFile-web" fileName="nlog-own-${shortdate}.log"

???????????? layout="${longdate}|${logger}|${uppercase:${level}}|? ${message} ${exception}" />

?

??? <target xsi:type="Null" name="blackhole" />

? </targets>

?

? <rules>

??? <!--All logs, including from Microsoft-->

??? <logger name="*" minlevel="Trace" writeTo="allfile" />

?

??? <!--Skip Microsoft logs and so log only own logs-->

??? <logger name="Microsoft.*" minlevel="Trace" writeTo="blackhole" final="true" />

??? <logger name="*" minlevel="Trace" writeTo="ownFile-web" />

? </rules>

</nlog>

?

2).使用NuGet安裝相關日志組件

? NLog.Extensions.Logging

? NLog.Web.AspNetCore

?

3).將nlog.config文件配置到環境中并進行日志注冊

? ??????

??????? public void Configure(IApplicationBuilder app, IHostingEnvironment env,ILoggerFactory loggerFactory)

??????? {

??????????? //添加日志配置路徑

??????????? env.ConfigureNLog("nlog.config");

??????????? //注冊WEB日志

??????????? loggerFactory.AddNLog();

??????????? app.AddNLogWeb();

?

??????????? //注冊控制臺日志

??????????? loggerFactory.AddConsole(Configuration.GetSection("Logging")); //控制臺日志添加

??????????? loggerFactory.AddDebug();

?

?

??????????? if (env.IsDevelopment())

??????????? {

??????????????? app.UseDeveloperExceptionPage();

??????????? }

??????????? else

??????????? {

??????????????? app.UseExceptionHandler("/Home/Error");

??????????? }

?

??????????? //添加靜態文件中間件

??????????? app.UseStaticFiles();

??????????? //異常中間件

??????????? app.UseExceptionHandler();

?

??????????? app.UseMvc(routes =>

??????????? {

??????????????? //默認路由

??????????????? routes.MapRoute(

??????????????????? name: "default",

??????????????????? template: "{controller=Home}/{action=Login}");

??????????? });

??????? }

?
