Question

We have a supplier that fires an HTTP post without using query strings. Effectively they post to our application in the following format:

www.mydomain.com/ourHandler/GroupId/ProductId/ItemId/CustomerId/ 

ourHandler (or Tracker) and GroupId is the only guaranteed values. The rest are completely optional. The slash on the end could be missing, too. I’m told that I need to cater for “hundreds of hits a second”.

So I thought the best option might be to use a regex (which I suck at) instead of string.split.

Here’s what I got but obviously it’s not good enough:

^(?<tracker>.\w*)?/(?<GroupId>\w*)?/(?<ProductId>\w)?/(?<ItemId>\w*)?(/)?(?<CustomerId>\w*)?

Answer 1

Why do you need Regex? Uri class has a Segments property

var uri = new Uri("http://www.mydomain.com/ourHandler/GroupId/ProductId/ItemId/CustomerId/");
var segments = uri.Segments;
//ourHandler/ <-- segments[1] 
//GroupId/ <-- segments[2]
