当我使用Breeze JS查询我的REST服务时，参数未通过

Question

我正在与AngularJS和BreezeJS合作开发SPA。后端在ASP.NET Core MVC 6和EF 6.1.3上实现。

REST服务正在运行，但是当我使用Breeze JS查询服务时，不会传递参数。

E.g。

  [HttpGet]
  [EnableQuery]
  public IQueryable<Event> Events()
  {
  return this._contextProvider.Context.Events;
  }

我试图通过浏览器调用该服务... /上下文/事件？$ filter =（Id％20eq％202）。结果仍然相同，过滤器不适用。

我错过了什么？如何将OData添加到MVC6？

我的控制器：
