不同路由的同一控制器中的 AmbiguousActionException

Question

I have a controller getting AmbiguousActionException. I have 3 methods I want to perform 1. Get a member based on their Id 2. Find all members with certain eye color 3. Get all members

The first works fine but 2 and 3 get AmbiguousActionException I assume because they both only use HTTPGet and nothing else. Is there a way I can differentiate between a default HTTPGet with a query parameter and HTTPGet. I'm using a query parameter as the eyecolor filter criteria, not a key for the member.

Here is my code:

namespace MyController.Controllers
{
    [Route("members")]
    public class MemberController: Controller
    {
        [HttpGet("{memberId}")]
        public IActionResult GetMemberFor(string memberId)
        {
            return Ok(DoSomeMethodWithId(memberId));
        }

        [HttpGet(Name = "FindMembersWith")]
        public IActionResult FindMembersFor([FromQuery(Name = "eyeColor")] string eyeColor)
        {
            return Ok(DoSomeOtherMethodWithFilter(eyeColor);
        } 

        [HttpGet(Name = "GetAllMembers")]
        public IActionResult GetAllMembers()
        {
            return Ok(DoMethodToRetrieveAllMembers);
        }
    }
}

urls:
www.mysite.com/members/{id} -- get single member by id
www.mysite.com/members  -- get all members
www.mysite.com/members?eyeColor=blue  --get all members with blue eyes

Is there something I can add to make the 2nd and 3rd routes work?

Answer 1

You can add custom routes:

[Route("FindMembersWith")]
[HttpGet]
public IActionResult FindMembersFor([FromQuery(Name = "eyeColor")] string eyeColor)
{
   return Ok(DoSomeOtherMethodWithFilter(eyeColor);
} 

[Route("GetAllMembers")]
[HttpGet]
public IActionResult GetAllMembers()
{
    return Ok(DoMethodToRetrieveAllMembers);
}
