How to log HttpClient requests in Kentico Kontent .NET Delivery Client?

How do you log the HTTP Requests that the Kentico Kontent .NET delivery API here: https://github.com/Kentico/kontent-delivery-sdk-net

Specifically what I am looking for is how to log the HTTP Get requests to delivery.kentico.ai (the end point that you retrieve your content JSON from).

Solution

  • You can enrich and inject an HttpClient to the DeliveryClient.

    Enrich:

        public class LoggingHandler : DelegatingHandler
    {
        public LoggingHandler(HttpMessageHandler innerHandler, Microsoft.Extensions.Logging.ILogger logger)
            : base(innerHandler)
        {
            Logger = logger;
        }

        public Microsoft.Extensions.Logging.ILogger Logger { get; }

        protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
        {
            Logger.LogInformation(request.Method + " " + request.RequestUri);

            HttpResponseMessage response = await base.SendAsync(request, cancellationToken);

            Logger.LogInformation(response.StatusCode + " " + response.Content.Headers);
            return response;
        }
    }

    Use e.g. Serilog

            services.AddLogging(builder =>
        {
            // Add Serilog
            builder.AddSerilog(new LoggerConfiguration()
                    .MinimumLevel.Information()
                    .WriteTo.File("logs\\log.log", rollingInterval: RollingInterval.Day)
                    .CreateLogger());
        });

        var serviceProvider = services.BuildServiceProvider();
        var logger = serviceProvider.GetRequiredService<ILogger<Startup>>();

        HttpClient httpClient = new HttpClient(new LoggingHandler(new HttpClientHandler(), logger));

        var deliveryOptions = new DeliveryOptions();
        Configuration.GetSection(nameof(DeliveryOptions)).Bind(deliveryOptions);

    Inject:

            var deliveryClient = DeliveryClientBuilder
            .WithOptions(_ => deliveryOptions)
            .WithHttpClient(httpClient)
            .Build();
