.Net 6 Webapi Core 添加日志管理(Serilog)，将日志输出到控制台、数据库、文本文件中

目录

首先引用配置Serilog的NueGet包

Program.cs 添加如下代码

使用方法

测试应用

• 首先引用配置Serilog的NueGet包

Serilog

Serilog.AspNetCore

Serilog.Formatting.Compact

Serilog.Sinks.File

Serilog.Sinks.MySQL

• Program.cs 添加如下代码

先封装一个类：

这里的将日志输出到数据库我给注释掉了，需要的伙伴可以解除注释哦

 public static class InitScoped{/// 
/// 注入容器/// 
/// public static void Register(this IServiceCollection services) {services.AddScoped();}/// 
/// Serilog 日志拓展/// 
public static void ConfigureLogging(WebApplicationBuilder builder){string dateFile = DateTime.Now.ToString("yyyyMMdd");Log.Logger = new LoggerConfiguration().MinimumLevel.Override("Microsoft", LogEventLevel.Warning).Enrich.FromLogContext().WriteTo.Console(new CompactJsonFormatter())//.WriteTo.MySQL(connectionString: builder.Configuration.GetConnectionString("DbConnectionString"), tableName: "Logs") // 输出到数据库.WriteTo.Logger(configure => configure.Filter.ByIncludingOnly(e => e.Level == LogEventLevel.Debug).WriteTo.File($"logs/log-debug-{dateFile}.txt",rollingInterval: RollingInterval.Day,outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Exception}")).WriteTo.Logger(configure => configure.Filter.ByIncludingOnly(e => e.Level == LogEventLevel.Information).WriteTo.File($"logs/log-info-{dateFile}.txt",rollingInterval: RollingInterval.Day,outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Exception}")).WriteTo.Logger(configure => configure.Filter.ByIncludingOnly(e => e.Level == LogEventLevel.Error).WriteTo.File($"logs/log-error-{dateFile}.txt",rollingInterval: RollingInterval.Day,outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Exception}")).WriteTo.File($"logs/log-total-{dateFile}.txt",rollingInterval: RollingInterval.Day,outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Exception}",restrictedToMinimumLevel: LogEventLevel.Debug).CreateLogger();}}

Program.cs 调用此方法

#region 配置Serilog 日志InitScoped.ConfigureLogging(builder);builder.Host.UseSerilog(); //向主机注册Serilog#endregion

• 使用方法

直接在需要使用的控制器或方法类下进行注入即可，示例代码如下

 public class DalTarget : BllTarget{private readonly ServerContext _context;private readonly ILogger _logger;public DalTarget(ServerContext context, ILogger logger){_context = context;_logger = logger;}public async Task<List> GetTarget(Guid guid){try{var data = await _context.Targets.Where(s => s.Id == guid).AsNoTracking().ToListAsync();if (data.Count <= 0){throw new Exception("接口：GetTarget|报错：查询列表id返回空数据");}return data;}catch (Exception ex){_logger.LogInformation($"GetTarget:{ex.Message},参数|id：{guid}");_logger.LogError($"GetTarget:{ex.Message},参数|id：{guid}");throw new Exception(ex.Message);}} }

这里 的LogInformation 和 LogError 看情况写 我把两个都写出来了

• 测试应用

报错后会在项目地址自动创建log文件夹

控制台输出

好啦，今天分享到这里哦
