Multiple optional parameters web api attribute routing

Question

Hi guys i am new to attribute routing and not sure if this is even possible.

What i have is an attribute route which works fine like this

[HttpGet]
         


        

Answer 1

Use a query string.

[HttpGet]
    [Route("GetIssuesByFlag/{flag:int=3?}")]
    public IEnumerable GetIssuesByFlag(int flag, List tagIds, int? categoryId = null)

Url: /getissuesbyflag/1?tagIds=2,5,6&categoryId=56

You really should use query strings for optional parameters and path parameters if they are required.
