Can I Log all requests using Flurl.Http?

Question

Asp.NET core logs each request that enters based on configuration. Now i'd like to have the same functionality for Flurl requests i sent. Most notably, I of course would like to know when a requests fails or does not complete. For debugging I found logging all requests in a verbose matter was extremely helpful.

Sure can. For cross-cutting concerns like logging, you want to use Flurl's event handlers, specifically BeforeCall, AfterCall, OnError, and their async equivalents (BeforeCallAsync, AfterCallAsync, OnErrorAsync). Here's an error logging example:

private async Task HandleFlurlErrorAsync(HttpCall call) 
{
    await LogErrorAsync(call.Exception.Message);
    call.ExceptionHandled = true; // prevents exception from bubbling up, if desired
}

// Configure once at startup:
FlurlHttp.Configure(settings => settings.OnErrorAsync = HandleFlurlErrorAsync);
