Question

我只想将2个参数传递给控制器并运行我的sql-function 尝试搜索大量资源但没有运气，

谁能给我一些提示？

基本上我遵循这个Web API and OData- Pass Multiple Parameters

当我使用builder.Function编译器时，请告诉我没有找到扩展方法。

    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services
            ODataModelBuilder builder = new ODataConventionModelBuilder();

            //  config.Count().Filter().OrderBy().Expand().Select().MaxTop(null);

            var json = config.Formatters.JsonFormatter;
            json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
            config.Formatters.Remove(config.Formatters.XmlFormatter);



            config.Formatters.Remove(config.Formatters.XmlFormatter);
            config.Formatters.JsonFormatter.SerializerSettings.Formatting = Formatting.Indented;
            config.Formatters.JsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
            // var json = config.Formatters.JsonFormatter;
            // builder.EntitySet<Booking>("Bookings");
            builder.EntitySet<LiveBooking>("LiveBookings");

            builder.EntitySet<BookingInfo>("BookingInfoes");
            builder.EntitySet<LiveBookingByType>("LiveBookingByTypes");






            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(

                routeTemplate: "api/{controller}/{id}",

            );
            config.Routes.MapODataServiceRoute("odata", "odata/v4", builder.GetEdmModel());
            // config.MapODataServiceRoute( routeName: "ODataRoute", routePrefix: "odata/v4", model: builder.GetEdmModel());
        }

    }
}

Answer 1

您应该使用System.Web.OData.Builder代替System.Web.Http.OData.Builder。它应该在包Microsoft.AspNet.OData。

中

如果.GetEdModel()抛出异常，则定义可能有问题，而不是使用。

Answer 2

我遵循这种方法：

WebApiConfig.cs

using System.Web.Http;
using System.Web.OData.Extensions;
using System.Web.OData.Builder;
//using System.Web.OData.Extensions;
using wcod.Model;

namespace wcod
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services
            ODataModelBuilder builder = new ODataConventionModelBuilder();
            config.Count().Filter().OrderBy().Expand().Select().MaxTop(null);

            builder.EntitySet<TimeMarker>("TimeMarkers");

            var function = builder.Function("GetTimeMarkerSearch");
            function.Parameter<string>("bookID");
            function.Parameter<string>("keywords");
            function.ReturnsCollectionFromEntitySet<TimeMarker>("TimeMarkers");
                config.MapHttpAttributeRoutes();

            //config.Routes.MapODataServiceRoute("odata", "odata/v4", builder.GetEdmModel());

            config.MapODataServiceRoute("odata", "odata/v4", builder.GetEdmModel());
        }

    }
}

然后在我的Controller中，mycase TimeMarkersControllers

[HttpGet]
[ODataRoute("GetTimeMarkerSearch(bookID={bookID},keywords={keywords})")]
public IHttpActionResult WhateverName([FromODataUri]string bookID, [FromODataUri]string keywords){
// my logic
}

odata v4使用2参数
