serilog .net core 3.1 配置方式

安裝包dotnet add package Serilog dotnet add package Serilog.AspNetCore

早初始化模式

    public class Program
    {
        public static IConfiguration Configuration { get; } = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
            .AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", optional: true)
            .AddEnvironmentVariables()
            .Build();

        public static int Main(string[] args)
        {
            Log.Logger = new LoggerConfiguration()
                .ReadFrom.Configuration(Configuration)
                .Enrich.FromLogContext()
                .WriteTo.Debug()
                .WriteTo.Console(
                    outputTemplate: "[{Timestamp:HH:mm:ss} {Level:u3}] {Message:lj} {Properties:j}{NewLine}{Exception}")
                .CreateLogger();

            try
            {
                Log.Information("Getting the motors running...");

                CreateHostBuilder(args).Build().Run();

                return 0;
            }
            catch (Exception ex)
            {
                Log.Fatal(ex, "Host terminated unexpectedly");
                return 1;
            }
            finally
            {
                Log.CloseAndFlush();
            }
        }

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

        }

                .ConfigureWebHostDefaults(webBuilder => webBuilder.UseStartup<Startup>())
                .UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration
                    .ReadFrom.Configuration(hostingContext.Configuration)
                    .Enrich.FromLogContext()
