.NET 6.0 日志处理之Serilog 写入到sql server（一）

.NET 6.0里使用Serilog 写入日志到sql server数据库表。

1、安装依赖包

Serilog:

Serilog.Sinks.MSSqlServer:

Serilog.AspNetCore:

2、添加静态类SerilogConfig

using Serilog;
using Serilog.Sinks.MSSqlServer;
using System.Collections.ObjectModel;
using System.Net;namespace Demo_Serilog.Function;public static class SerilogConfig
{public static void CreateLogger(){try{var filePath = Path.Combine(AppContext.BaseDirectory, "Logs/Serilog/log.txt");var logDB = @"Server=192.168.0.0;Database=DB;User ID=Admin;Password=123456;TrustServerCertificate=true;";var sinkOpts = new MSSqlServerSinkOptions();sinkOpts.TableName = "Logs";sinkOpts.AutoCreateSqlTable = false;sinkOpts.BatchPostingLimit = 100;sinkOpts.BatchPeriod = TimeSpan.FromMilliseconds(1);var columnOpts = new ColumnOptions();columnOpts.Store.Remove(StandardColumn.MessageTemplate);columnOpts.Store.Remove(StandardColumn.Properties);//columnOpts.Properties.ExcludeAdditionalProperties = true;columnOpts.AdditionalColumns = new Collection<SqlColumn>{new SqlColumn{DataType = System.Data.SqlDbType.VarChar, DataLength = -1, ColumnName = "SourceContext"},new SqlColumn{DataType = System.Data.SqlDbType.VarChar, DataLength = 50, ColumnName = "LineId"}};Log.Logger = new LoggerConfiguration().MinimumLevel.Information().Enrich.FromLogContext().Enrich.WithProperty("LineId", "Web").WriteTo.MSSqlServer(connectionString: logDB,sinkOptions: sinkOpts,columnOptions: columnOpts).CreateLogger();}catch (Exception ex){ }     }public static void RefreshLogger(){if (Log.Logger != null){Log.CloseAndFlush();}CreateLogger();}private static string GetIpAddress(){string ipAddress = "127.0.0.1";IPAddress[] ips = Dns.GetHostAddresses(Dns.GetHostName());foreach (IPAddress ip in ips){if (ip.AddressFamily.ToString().ToLower().Equals("internetwork")){ipAddress = ip.ToString();return ipAddress;}}return ipAddress;}
}

3、Program.cs中配

using Demo_Serilog;
using Demo_Serilog.Function;
using Serilog;
using Serilog.Settings.Configuration;SerilogConfig.CreateLogger();
Log.Information("Starting web application");try
{var builder = WebApplication.CreateBuilder(args); //创建一个Web应用程序构建器。LineConsts.InitConfig(builder.Configuration);builder.Host.UseSerilog();//配置Serilog。builder.Services.AddControllers();//向依赖注入容器添加控制器服务。// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbucklebuilder.Services.AddEndpointsApiExplorer(); //用于API文档生成。builder.Services.AddSwaggerGen();//添加Swagger生成器，生成API文档。var app = builder.Build(); //构建Web应用程序。// Configure the HTTP request pipeline.if (app.Environment.IsDevelopment())  //检查当前环境是否是开发环境。{app.UseSwagger(); //启用Swagger中间件，提供API文档UI。app.UseSwaggerUI();}app.UseHttpsRedirection(); //强制使用HTTPS。app.UseAuthorization(); //启用授权中间件。app.MapControllers(); //将控制器映射到路由app.Run(); //运行Web应用程序。
}
catch (Exception ex)
{Log.Fatal(ex, "Web服务异常退出");
}

4、日志表：

5、写入日志测试样例：

using Microsoft.AspNetCore.Mvc;
using Serilog;namespace Demo_Serilog.Controllers
{    [ApiController][Route("[controller]")]public class WeatherForecastController : ControllerBase{private static readonly string[] Summaries = new[]{"Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"};public WeatherForecastController(){}[HttpGet(Name = "GetWeatherForecast")]public IEnumerable<WeatherForecast> Get(){try{Log.Information("Get");if (Summaries.Length > 0){throw new Exception("Error Created By SomeOne.");}return Enumerable.Range(1, 5).Select(index => new WeatherForecast{Date = DateTime.Now.AddDays(index),TemperatureC = Random.Shared.Next(-20, 55),Summary = Summaries[Random.Shared.Next(Summaries.Length)]}).ToArray();}catch (Exception ex){Log.Error("Error:" + ex.Message);return Enumerable.Empty<WeatherForecast>();}           }}
}

6、运行结果：
