1.开源日志组件源码:  https://github.com/alaatm/Sejil

2.下载下来发现里面对于不同的.net core 版本的配置提供了对应的示例

.Net Core 3.1

Program.cs文件中

public class Program
    {
        public static void Main(string[] args) => CreateHostBuilder(args).Build().Run();

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .UseSejil()
                .ConfigureWebHostDefaults(webBuilder => webBuilder.UseStartup<Startup>());
    }

Startup.cs

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Sejil;

 public class Startup
    {
        public IConfiguration Configuration { get; }

        public Startup(IConfiguration configuration) => Configuration = configuration;

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();
            services.ConfigureSejil(cfg => cfg.Title = "Logs");
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }
            app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseSejil();

            app.UseRouting();

            app.UseEndpoints(endpoints =>
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}"));
        }
    }

如果需要权限校验之类的

Program.cs文件中

public class Program
    {
        public static void Main(string[] args)
        {
            AppContext.SetSwitch("System.Net.Http.UseSocketsHttpHandler", false);
            CreateHostBuilder(args).Build().Run();
        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .UseSejil()
                .ConfigureWebHostDefaults(webBuilder => webBuilder.UseStartup<Startup>());
    }

Startup.cs 文件中

using Bazinga.AspNetCore.Authentication.Basic;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Sejil;

   public class Startup
    {
        public IConfiguration Configuration { get; }

        public Startup(IConfiguration configuration) => Configuration = configuration;

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();

            services.AddAuthentication(BasicAuthenticationDefaults.AuthenticationScheme)
                .AddBasicAuthentication(credentials =>
                    Task.FromResult(credentials.username == "myUsername" && credentials.password == "myPassword")
                );

            services.ConfigureSejil(cfg => cfg.AuthenticationScheme = BasicAuthenticationDefaults.AuthenticationScheme);
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }
            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthentication();
            app.UseAuthorization();
            app.UseSejil();

            app.UseEndpoints(endpoints =>
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}"));
        }
    }

对应的 appsettings.json 配置文件

"Authentication": {
        "Authority": "https://sample.auth0.com",
        "ResponseType": "code",
        "ClientId": "USER_SECRET",
        "ClientSecret": "USER_SECRET",
        "Scope": [
            "openid",
            "profile",
            "email"
        ],
        "CallbackPath": "/signin-auth0",
        "ClaimsIssuer": "Auth0"
    }

.Net Core 6

using Sejil;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddRazorPages();

// Configure Sejil
builder.Host.UseSejil(
    minLogLevel: LogLevel.Information,
    writeToProviders: true);

builder.Services.ConfigureSejil(cfg => cfg.Title = "My App Logs");
//////////////////

var app = builder.Build();

if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthorization();

app.MapRazorPages();

// Add sejil to request pipeline
app.UseSejil();
//////////////////

app.Run();

另外补充一下: 源代码里面是 在本地  C:\Users\{电脑名}\AppData\Local\ 项目 下新建了 一个sqlite 文件

如果是项目发布,是在运行程序目录下 新建一个 业务文件夹\sqlite文件

访问 http://localhost:xxxx/Sejil   就可以看到对应的日志了.
