简单路由：未找到与请求URI匹配的HTTP资源

Question

我的WebApiConfig中有两条简单的路线：

config.Routes.MapHttpRoute(
name: "Speaker",
routeTemplate: "api/presentations/{presentationid}/speakers/{id}",
defaults: new { controller = "speakers", id = RouteParameter.Optional }
);

config.Routes.MapHttpRoute(
name: "Presentations",
routeTemplate: "api/presentations/{id}",
defaults: new { controller = "presentations", id = RouteParameter.Optional }
);

我无法获得第一条工作路线..我有一个带有Get的SpeakersController：

IEnumerable<SpeakerModel> Get(int presentationid)
{
return _speakerService.GetSpeakersByPresentationId(presentationid).Select(s => _modelFactory.Create(s));
}

当我通过get请求调用http://localhost/Api/Presentations/1/Speakers时，我收到此错误：

＆＃34;消息＆＃34;：＆＃34;未找到与请求URI匹配的HTTP资源＆＃39; http://localhost/Api/Presentations/1/Speakers＆＃39;。＆＃34;， ＆＃34; MessageDetail＆＃34;：＆＃34;未在控制器上发现任何操作＆＃39;扬声器＆＃39;与请求匹配。＆＃34;

Answer 1

我的方法上没有公共访问修饰符。

**public** IEnumerable<SpeakerModel> Get(int presentationid)
{
return _speakerService.GetSpeakersByPresentationId(presentationid).Select(s =>     _modelFactory.Create(s));
}
