.NET Core 下使用 Serilog 记录日志
Serilog
Like many other libraries for .NET, Serilog provides diagnostic logging to files, the console, and elsewhere. It is easy to set up, has a clean API, and is portable between recent .NET platforms.
Unlike other logging libraries, Serilog is built with powerful structured event data in mind.
最佳实践
控制台项目
在项目中添加下面几个组件包
Install-Package Serilog.Extensions.Logging
Install-Package Serilog.Sinks.Console
Install-Package Serilog.Sinks.File
class Program
{
static async Task Main(string[] args)
{
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Information()
.MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
#if DEBUG
.MinimumLevel.Override("Xxx", LogEventLevel.Debug)
#else
.MinimumLevel.Override("Xxx", LogEventLevel.Information)
#endif
.Enrich.FromLogContext()
.WriteTo.File(Path.Combine(Directory.GetCurrentDirectory(), "Logs/logs.txt"))
.WriteTo.Console()
.CreateLogger();
await CreateHostBuilder(args).RunConsoleAsync();
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureLogging((context, logging) => logging.ClearProviders())
.ConfigureServices((hostContext, services) =>
{
services.AddHostedService<XxxHostedService>();
});
}
//XxxHostedService.cs
public class XxxHostedService : IHostedService
{
private readonly IHostApplicationLifetime _hostApplicationLifetime;
public XxxHostedService(IHostApplicationLifetime hostApplicationLifetime)
{
_hostApplicationLifetime = hostApplicationLifetime;
}
public async Task StartAsync(CancellationToken cancellationToken)
{
using var application = AbpApplicationFactory.Create<XxxModule>(options =>
{
options.UseAutofac();
options.Services.AddLogging(c => c.AddSerilog());
});
application.Initialize();
var service = await application.ServiceProvider.GetRequiredService<XxxService>();
service.XxxAsync();
application.Shutdown();
_hostApplicationLifetime.StopApplication();
}
public Task StopAsync(CancellationToken cancellationToken) => Task.CompletedTask;
}
AspNetCore项目
在项目中添加下面几个组件包
Install-Package Serilog.AspNetCore
Install-Package Serilog.Sinks.Async
Install-Package Serilog.Sinks.File
public static async Task Main(string[] args)
{
Log.Logger = new LoggerConfiguration()
#if DEBUG
.MinimumLevel.Debug()
#else
.MinimumLevel.Information()
#endif
.MinimumLevel.Override("Microsoft", LogEventLevel.Information)
.Enrich.FromLogContext()
.WriteTo.Async(c => c.File($"Logs/{DateTime.Now:yyyy/MMdd}/logs.txt"))
.CreateLogger();
try
{
Log.Information("Starting Xxx.");
await CreateHostBuilder(args).Build().RunAsync();
}
catch (Exception ex)
{
Log.Fatal(ex, "Xxx terminated unexpectedly!");
}
finally
{
Log.CloseAndFlush();
}
}
internal static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseIISIntegration()
.UseStartup<Startup>();
}).UseAutofac().UseSerilog();
}
