1. Nu包安装Serilog.ASPNetCore和Serilog.Sinks.File

2. 在APPSettings中添加Serilog注入

  "Serilog": {
    "WriteTo": [
      {
        "Name": "File",
        "Args": {
          "path": "logs/log.txt",
          "rollingInterval": "Day",
          "outputTemplate": "Occurrence Time: {Timestamp:HH:mm:ss.fff} Level: {Level} Detailed Information: {Message}{NewLine}{Exception}"
        }
      }
    ]
  },

3. 在Program.cs中注册Serilog的引用

using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Hosting;
using Serilog;
using System;

namespace SuperNode.WebApi
{
    public class Program
    {
        public static void Main(string[] args)
        {
            Log.Logger = new LoggerConfiguration().
                MinimumLevel.Debug().
                MinimumLevel.Override("Microsoft", Serilog.Events.LogEventLevel.Information)
                .ReadFrom.Configuration(new ConfigurationBuilder()
                .AddJsonFile("appsettings.json")
                .Build())
                .Enrich.FromLogContext().
                 /*WriteTo.File(Path.Combine("logs", @"log.txt"), (Serilog.Events.LogEventLevel)RollingInterval.Day, outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Exception}").
                  .WriteTo.MSSqlServer("Data Source=DESKTOP-4TU9A6M;Initial Catalog=CoreFrame;User ID=sa;Password=123456", "logs", autoCreateSqlTable: true, restrictedToMinimumLevel: LogEventLevel.Information)*/
                 CreateLogger();

            try
            {
                Log.Information("SuperNode.DataPrivilegeCenter");
                CreateHostBuilder(args).Build().Run();
            }
            catch (Exception ex)
            {
                Log.Fatal(ex, "Host terminated unexpectedly");
            }
            finally
            {
                Log.CloseAndFlush();
            }
        }

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

4. 在Controller中使用

[Route("api/[controller]")]
    [ApiController]
    public class TestController : ControllerBase
    {
        private readonly ILogger<TestController> _logger;

        public TestController(ILogger<TestController> logger)
        {
            _logger = logger;
        }

        [HttpGet("getById")]
        public string Get()
        {
            return "Hello Web API World";
        }

        [HttpPost]
        public string Add()
        {
            return "";
        }

        [HttpPut]
        public string Put()
        {
            return "";
        }

        [HttpDelete]
        public string Delete()
        {
            return "";
        }
    }
