How to get id from paths in Grapevine

Question

Its a simple question, but I haven't found any documentation. Grapevine 4.2.2

        //GET id
        [RestRoute(HttpMethod = HttpMethod.GET, PathInfo = "/api/[id]")]
        public IHttpContext GetDataId(IHttpContext context)
        {
            //how to get id?
        }

Answer 1

This happens as soon as you write a question, the answer will appear.

    //GET id
    [RestRoute(HttpMethod = HttpMethod.GET, PathInfo = "/api/[id]")]
    public IHttpContext GetDataId(IHttpContext context)
    {
        var id = context.Request.PathParameters["id"];
    }
