ASP.. NET Web API OData批量返回HTTP 404

Question

我正在开始使用ASP。. NET Web API v2和OData (v3)。
我有一个客户端与JayData v 1.3.6

<<p> 客户端上下文/strong>

onlinedb = new $todo.Types.ToDoContext({
    name: 'oData',
    oDataServiceHost: 'http://localhost:49375/odata'
});

服务器线路

public static void Register(HttpConfiguration config)
{
    // Web API configuration and services
    ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
    builder.ContainerName = "WebAPIDataCollectorContext";
    builder.EntitySet<TodoItem>("Todo");
    config.Routes.MapODataRoute("odata", "odata", builder.GetEdmModel(), new DefaultODataBatchHandler(GlobalConfiguration.DefaultServer));
    // Web API routes
    config.MapHttpAttributeRoutes();
    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );
    config.EnableCors();
}

请求
OPTIONS/odata/$batch HTTP/1.1

响应

{"Message":"No HTTP resource was found that matches the request URI 'http://localhost:49375/odata/$batch'.","MessageDetail":"No route providing a controller name was found to match request URI 'http://localhost:49375/odata/$batch'"}

评论

http://localhost:49375/odata/Todo (GET operation) is working fine.

问题是:为什么批处理操作失败?

谢谢!

ASP不支持批处理操作。. NET WebAPI OData，但您可以按照本文进行配置——在WebAPI和WebAPI OData中引入批处理支持
