救救孩子吧!http get方法传俩个参数报错。

Question

如图所示，输入以上URL时报错。服务器上的代码为

 [RoutePrefix("api/WorkflowNodeList")]
    public class WorkflowNodeListController : ApiController
    {
        private hlxEntities db = new hlxEntities();

        [ResponseType(typeof(WorkflowNodeList))]

        // GET api/<controller>
        [HttpGet]
        public IHttpActionResult Getnodelist(string model,string key)
        {

            WorkflowNodeList nodeList = db.WorkflowNodeList.Where(q => q.model_id == int.Parse(model) & q.key_str == key).SingleOrDefault();
            if (nodeList == null)
            {
                return NotFound();
            }

            return Ok(nodeList);

        }

整个controller就这一个get方法就很迷，我该怎么才能获得我想要的返回值呢？

namespace hlx_service
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services
            config.Formatters.Clear();
            config.Formatters.Add(new JsonMediaTypeFormatter());
            //.var jsonFormatter = new JsonMediaTypeFormatter();
            //config.Services.Replace(typeof(IContentNegotiator), new JsonContentNegotiator(jsonFormatter));
            // Web API routes
            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
        }
    }
}

config 里是这样的。

你请求的路径只到了控制器，没有到action，Getnodelist

应该是/api/WorkflowNodeListController/Getnodelist?参数
