.netcore 自帶日誌組件的配置

日誌配置

 "Logging": {
    "IncludeScopes": false,
    "Debug": {
      "LogLevel": {
        "Default": "Debug"
      }
    },
    "Console": {
      "LogLevel": {
        "Default": "Information"
      }
    },
    "LogLevel": {
      "Default": "Information"
    }

在ConfigureServices 方法中添加

      services.AddLogging(loggingBuilder => {
                loggingBuilder.AddConfiguration(Configuration.GetSection("Logging"));
                loggingBuilder.AddConsole();
                loggingBuilder.AddDebug();
            });

或者通過構建IHttpHostBuild時候添加

    public static IWebHostBuilder CreateDefaultBuilder(string[] args)
    {
        var builder = new WebHostBuilder()
            .UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            .ConfigureAppConfiguration((hostingContext, config) =>
            {
                var env = hostingContext.HostingEnvironment;

                config.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
                      .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true, reloadOnChange: true);

                if (env.IsDevelopment())
                {
                    var appAssembly = Assembly.Load(new AssemblyName(env.ApplicationName));
                    if (appAssembly != null)
                    {
                        config.AddUserSecrets(appAssembly, optional: true);
                    }
                }

                config.AddEnvironmentVariables();

                if (args != null)
                {
                    config.AddCommandLine(args);
                }
            })
            .ConfigureLogging((hostingContext, logging) =>
            {
                logging.UseConfiguration(hostingContext.Configuration.GetSection("Logging"));
                logging.AddConsole();
                logging.AddDebug();
            })
            .UseIISIntegration()
            .UseDefaultServiceProvider((context, options) =>
            {
                options.ValidateScopes = context.HostingEnvironment.IsDevelopment();
            })
            .ConfigureServices(services =>
            {
                services.AddTransient<IConfigureOptions<KestrelServerOptions>, KestrelServerOptionsSetup>();
            });

        return builder;
    }
