配置过程
-
安装NLog
通过Nuget进行集成(NuGet Gallery | NLog.Web.AspNetCore 4.14.0)
通过命令行安装
Install-Package NLog.Web.AspNetCore -Version 4.14.0
通过可视化管理工具查找并安装
NLog.Web.AspNetCore
-
修改Program.cs
public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureLogging((context, builder) => { // 适配原来的Log配置 builder.AddConfiguration(context.Configuration.GetSection("Logging")); builder.AddConsole(); builder.AddDebug(); builder.AddEventSourceLogger(); // 以下关键配置 builder.AddNLogWeb(); builder.AddNLog(); // 关键配置结束 }) .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseUrls("http://*:5000"); webBuilder.UseStartup<Startup>(); });
-
配置Startup.cs
public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { ...... // 在UseEndpoints之前增加如下增加对部分 Layout renderers 的支持 app.Use(async (context, next) => { context.Request.EnableBuffering(); await next(); }); ...... }
-
增加NLog.config
注意此文件配置为复制到输出目录
每一项的配置可以参考下方的NLog配置项
