How can I get current request id?

[Wojciech Ziska]

Hi,
Although it's very helpful to have request id included in logs, I would also like to return this Id to the user on error screen. I know I can get it directly from current HttpContext, but it might not be there yet and I have to know internals of HttpRequestIdEnricher.

Thanks

Hi @wziska,

Instead of HttpRequestIdEnricher, you can use HttpRequestTraceIdEnricher, which uses an id pre-allocated by ASP.NET (may even be IIS, actually):

var serviceProvider = (IServiceProvider)HttpContext.Current;
var workerRequest = (HttpWorkerRequest)serviceProvider.GetService(typeof(HttpWorkerRequest));
var requestId = workerRequest.RequestTraceIdentifier;

HTH!

Unfortunately I'm getting Guid.Empty from RequestTraceIdentifier. Tried to add <httpTracing> element to web.config, but it didn't help.

Thanks for the investigation. Build 1.1 of the package (CI should publish soon) now has HttpRequestIdEnricher.TryGetCurrentHttpRequestId(). Cheers!

Thanks for quick feedback. I initially though about extension method for HttpContextExtensions , but static method in HttpRequestIdEnricher works too.

Regards.
