如何覆盖 ASP.NETCORE 路由？

Question

how can i use parameter routing?
my project use.Net 6.0
like:
https://localhost:7203/v1/users/123/items?action=delete
and
https://localhost:7203/v1/users/123/items?action=claim

i want use code

[HttpPost]
[Route("/v1/users/{userId}/items")]
public void Delete(string userId)
{
   //TODO...
}

[HttpPost]
[Route("/v1/users/{userId}/items")]
public void Claim(string userId)
{
   //TODO...
}

Answer 1

[HttpPost("/v1/users/{userId}/items")]
public void PerformUserItemAction([FromRoute] string userId, [FromQuery] string action)
{
   if (action == "delete")
   {
      //...perform delete
   }
   else if (action == "claim")
   {
     //...perform claim action
   }
}

Answer 2

If you really need use POST to execute delete action
then your parameter name MUST the same as action's parameter
example:
if your uri is https://localhost:7203/v1/users/123/items?action=delete

[HttpPost]
[Route("/v1/users/{userId}/items")]
public void Delete([FromRoute]string userId, string action)
{
   // Use your action string to decide action 
}

BUT it is better to specify httpDelete to your delete action

Like HsuTingHuan said. It is probably better to use the correct HttpRequestMethods like [HttpDelete] for the delete action. But if you really need to do it like you said try this:

[Route("/v1/users/{userId}/items?action=claim")]

[Route("/v1/users/{userId}/items?action=delete")]
