NET5集成 NLOG

1. 安装包

	<ItemGroup>
		<PackageReference Include="NLog" Version="4.7.13" />
		<PackageReference Include="NLog.Schema" Version="4.7.13" />
		<PackageReference Include="NLog.Web.AspNetCore" Version="4.14.0" />
	</ItemGroup>

2. program.cs配置

 public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host
            .CreateDefaultBuilder(args)
            .ConfigureLogging((context, logging) =>
            {
                logging.AddConfiguration(context.Configuration.GetSection("logging"));
                logging.AddConsole();
                logging.AddDebug();
                logging.AddEventSourceLogger();
            }).UseNLog()
            .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                })
            .UseServiceProviderFactory(new AutofacServiceProviderFactory()) //自动注入
            ;
    }

3. 配置文件配置 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" >
	<targets>
		<!--这个目标:最终输出文件类型, 位于根目录中得logs文件夹中, 名称以每日得时间一次生成log文件 , layout: 这个选项为生成的格式-->
		<target xsi:type="File" name="fileLog"
				fileName="${basedir}/logs/${shortdate}.log"
				layout="${longdate} ${uppercase:${level}} ${message}"
				maxArchiveFiles="5"
				archiveAboveSize="10240"
				archiveEvery="Day"/>

		<!--使用可自定义的着色将日志消息写入控制台-->
		<target xsi:type="ColoredConsole"  name="consoleLog"
                layout="[${date:format=HH\:mm\:ss}]:${message} ${exception:format=message}" />
	</targets>

	<rules>
		<!--设定了一个Debug得路由, 最终指向了一个 fileLog 名称得目标 -->
		<logger name="*" minlevel="Trace" writeTo="fileLog" />
		<logger name="*" minlevel="Trace" writeTo="consoleLog" />
	</rules>
</nlog>
