我正在开发“ Code Camper ”示例 SPA 应用程序。我在安装了 MVC 4 的 VS 2010 上运行该应用程序。但是我遇到了 LookupsController 的问题。

这是我得到的错误：

    "exceptionMessage":"Multiple actions were found that match the request: \r\nSystem.Collections.Generic.IEnumerable`1[CodeCamper.Model.Room] GetRooms() on type
 CodeCamper.Controllers.LookupsController\r\nSystem.Collections.Generic.IEnumerable`1[CodeC
amper.Model.TimeSlot] GetTimeSlots() on type 
CodeCamper.Controllers.LookupsController","exceptionType":"System.InvalidOperationException

我找到了答案！

当你创建一个 web api 项目时，默认情况下 global.asax.cs 中有这行代码

WebApiConfig.Register(GlobalConfiguration.Configuration);

我删除了它（正如我从 codecamper 的源代码中看到的那样），现在没有问题了！但我不知道为什么
