webapi請求

Put 更新

Delete 刪除

Post 添加

Get 獲取

 

當一個控制器裏有多個Delete時例如 ProductsController 有一個Delete和DeleteProduct方法，調用 時

 $.ajax({
                type: "DELETE",
                url: "products/" + id,
                success: list()
            });

會報異常{"Message":"發生錯誤。","ExceptionMessage":"找到了與該請求匹配的多個操做: \r\n類型 WebApi.Controllers.ProductsController 的 System.Collections.Generic.IEnumerable`1[WebApi.Models.Product] Delete(Int32)\r\n類型 WebApi.Controllers.ProductsController 的 System.Collections.Generic.IEnumerable`1[WebApi.Models.Product] DeleteProduct(Int32)","ExceptionType":"System.InvalidOperationException","StackTrace":"   在 System.Web.Http.Controllers.ApiControllerActionSelector.ActionSelectorCacheItem.SelectAction(HttpControllerContext controllerContext)\r\n   在 System.Web.Http.Controllers.ApiControllerActionSelector.SelectAction(HttpControllerContext controllerContext)\r\n   在 System.Web.Http.ApiController.ExecuteAsync(HttpControllerContext controllerContext, CancellationToken cancellationToken)\r\n   在 System.Web.Http.Dispatcher.HttpControllerDispatcher.SendAsyncInternal(HttpRequestMessage request, CancellationToken cancellationToken)\r\n   在 System.Web.Http.Dispatcher.HttpControllerDispatcher.SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)"}

因而可知webapi是根據請求的type去需找Delete方法的。
