Minimal API return result with StatusCode and Problem

The convention in our microservices is to return the result as follows:

    return result.StatusCode == (int) HttpStatusCode.Created
        ? StatusCode(result.StatusCode, result.MessageCode)
        : Problem(result.MessageCode, statusCode:result.StatusCode);

So making use of the StatusCode and Problem in Microsoft.AspNetCore.Mvc class ControllerBase.

We're adding a new microservice and figured we'd try to implement it as a Minimal API. Is there an equivalent for the Minimal API that follows the same structure?

Solution

  • Yes, you can use the Results class in minimal APIs. Here's an example.

    Map the endpoint:

    app.MapGet("getsomething", MyHandlerMethod);

    And the actual method:

    public IResult MyHandlerMethod() 
{
    var result = ...;

    return result.StatusCode == (int) HttpStatusCode.Created
        ? Results.StatusCode(result.StatusCode)
        : Results.Problem("Problem!) ;
}
