asp.net-core - ASP.NET CORE Web API Serilog 和 ElasticSearch 日志不能在 IIS 上工作，但在本地工作

Question

我配置了 .NET 5 Web API Serilog 和 Elasticsearch，当运行应用程序并从 REST 客户端发送请求时，它在本地正常工作。但是当我在 IIS 上发布它并向相同的端点发出相同的请求时，它并没有完全工作。在 IIS 上发布的应用程序中没有任何日志。

public class Program
    {
        public static void Main(string[] args)
        {
            ConfigureLogging();
            
            CreateHost(args);
        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                    webBuilder.UseWebRoot("client-app");
                })
                .ConfigureAppConfiguration(configuration =>
                {
                    configuration.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
                    configuration.AddJsonFile(
                        $"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT")}.json",
                        optional: true);
                })
                .UseSerilog();

        private static void ConfigureLogging()
        {
            var environment = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");
            var configuration = new ConfigurationBuilder()
                .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
                .AddJsonFile(
                    $"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT")}.json",
                    optional: true)
                .Build();

            Log.Logger = new LoggerConfiguration()
                .Enrich.FromLogContext()
                .Enrich.WithMachineName()
                .WriteTo.Debug()
                .WriteTo.Console()
                .WriteTo.Elasticsearch(ConfigureElasticSink(configuration, environment))
                .Enrich.WithProperty("Environment", environment)
                .ReadFrom.Configuration(configuration)
                .CreateLogger();
        }

        private static ElasticsearchSinkOptions ConfigureElasticSink(IConfigurationRoot configuration, string environment)
        {
            return new ElasticsearchSinkOptions(new Uri(configuration["ElasticConfiguration:Uri"]))
            {
                AutoRegisterTemplate = true,
                IndexFormat = $"{Assembly.GetExecutingAssembly().GetName().Name?.ToLower().Replace(".", "-")}-{environment?.ToLower().Replace(".", "-")}-{DateTime.UtcNow:yyyy-MM}"
            };
        }

        private static void CreateHost(string[] args)
        {
            try
            {
                CreateHostBuilder(args).Build().Run();
            }
            catch (System.Exception ex)
            {
                Log.Fatal($"Failed to start {Assembly.GetExecutingAssembly().GetName().Name}", ex);
                throw;
            }
        }
    }

弹性 uri 对 IIS 没有限制
