I'm trying to use Web API 2 attribute routing to set up a custom API. I've got my route working such that my function gets called, but for some reason I need to pass in my first parameter for everything to work properly. The following are the URLs I want to support:
http://mysite/api/servicename/parameter1
http://mysite/api/servicename/parameter1?parameter2=value2
http://mysite/api/servicename/parameter1?parameter2=value2¶meter3=value3
http://mysite/api/servicename/parameter1?parameter2=value2¶meter3=value3&p4=v4
The last 3 URLs work but the first one says "No action was found on the controller 'controller name' that matches the request."
My controller looks like this:
public class MyServiceController : ApiController
{
[Route("api/servicename/{parameter1}")]
[HttpGet]
public async Task<ReturnType> Get(string parameter1, DateTime? parameter2, string parameter3 = "", string p4 = "")
{
// process
}
}
Web API requires to explicitly set optional values even for nullable types...so you can try setting the following and you should see your 1st request succeed
DateTime? parameter2 = null
