使用2參數的odata v4

Question

我只想將2參數傳遞到控制器中並運行sql函數try並用大量谷歌搜索沒有運氣，

有人可以給我一些提示嗎？

基本上我遵循此Web API和OData-傳遞多個參數

當我使用builder.Function編譯器時，請告訴我未找到擴展方法。

Answer 1

您應該使用System.Web.OData.Builder而不是System.Web.Http.OData.Builder 。 它應該在Microsoft.AspNet.OData包中。

如果.GetEdModel()引發異常，則可能是您的定義有問題，而不是使用。

Answer 2

好吧，我遵循這種方法：

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());
        }

    }
}

然后在我的控制器中，mycase TimeMarkersControllers

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