Serilog.Enrichers.AspNetCore.HttpContext 1.0.0

Serilog Enrichers AspNetCore HttpContext

AspNetCore middleware to add to Serilog LogContext properties from HttpContext

Usage

Register this middleware as early as possible to use HttpContext properties in chained middlewares.

Code Sample

        public void ConfigureServices(IServiceCollection services)
        {
            LoggerConfiguration loggerConfiguration = new LoggerConfiguration();
            loggerConfiguration.Enrich.FromLogContext(); // mandatory
            loggerConfiguration.WriteTo.Console(
                outputTemplate:
                "[{Timestamp:HH:mm:ss} {Level:u3}] {EventId} {Message:lj} {Properties}{NewLine}{Exception}{NewLine}");

            Log.Logger = loggerConfiguration.CreateLogger();

            services.AddLogging(builder => builder.ClearProviders().AddSerilog(dispose: true));
        }

        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            app.UseSerilogLogContext(options =>
            {
                options.EnrichersForContextFactory = context => new[]
                {
                    // TraceIdentifier property will be available in all chained middlewares. And yes - it is HttpContext specific
                    new PropertyEnricher("TraceIdentifier", context.TraceIdentifier) 
                };
            });

            app.Run(async (context) =>
            {
                // No need to add TraceIdentifier as a parameter to "LogInformation" method
                context.RequestServices.GetRequiredService<ILoggerFactory>().CreateLogger("Demo").LogInformation("Hellow World Log. TraceId: {TraceIdentifier}");
                await context.Response.WriteAsync("Hello World!");
            });
        }

Console Optput
