                    .CreateLogger();

                Log.Information("Starting up");

                CreateHostBuilder(args).Build().Run();
            
            catch (Exception ex)
            
                Log.Fatal(ex, "Application start-up failed");
            
            finally
            
                Log.CloseAndFlush();
            

        

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .UseSerilog()
                .ConfigureWebHostDefaults(webBuilder =>
                
                    webBuilder.UseStartup<Startup>()
                    //.UseUrls("http://*:16586")
                    ;
                );
    

其他类里面手动记录日志：

//错误消息：
Log.Logger.Error($"请求地址:url|发送参数:json|异常消息:msg");

//信息                                
Log.Logger.Information("获取到样本MQ消息，1122");
