多个控制器上的属性路由匹配请求的 url

Question

我正在使用 web api 项目，其中我使用了两个控制器：

第一个控制器如下：

public class SmartlingController : BaseApiController
{
    [Route("api/smartling/ProcessSmartlingTranslation")]
    [VersionedRoute("", 1)]
    [ResponseType(typeof(HttpResponseMessage))]
    [HttpPost]
    public IHttpActionResult ProcessSmartlingTranslation(HttpRequestMessage request)
    {
       //some business logic
    }
}

第二控制器：

public class CommentsController : BaseApiController
{
    [Route("api/comments/GetAndPostBlogComments")]
    [VersionedRoute("", 1)]
    [ResponseType(typeof(HttpResponseMessage))]
    [HttpPost]
    public IHttpActionResult GetAndPostBlogComments([FromBody] BlogAndStoryComment comment)
    {
       //some business logic
    }
    [Route("api/comments/GetAndPostStoryComments")]
    [VersionedRoute("", 1)]
    [ResponseType(typeof(HttpResponseMessage))]
    [HttpPost]
    public IHttpActionResult GetAndPostStoryComments([FromBody] BlogAndStoryComment comment)
    {
       //some business logic
    }
}

下面是webapi注册方法：

public static void Register(HttpConfiguration config)
{
    // Web API routes
    config.MapHttpAttributeRoutes();
    config.Routes.MapHttpRoute(
        "DefaultApi",
        "api/{controller}/{action}/{id}",
        new { id = RouteParameter.Optional }
    );
    var f = new FormUrlEncodedMediaTypeFormatter();
    f.SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/json"));
    f.SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/x-www-form-urlencoded"));
    config.Formatters.Add(f);
    var enableCorsAttribute = new EnableCorsAttribute("*",
                                       "Origin, Content-Type, Accept",
                                       "GET, PUT, POST, DELETE, OPTIONS");
    config.EnableCors(enableCorsAttribute);
}

我的代码哪里出错了，我该如何解决这个问题？

示例中所有版本化路由的模板都是相同的。这就是路线冲突的原因。更新版本化路由模板以使其唯一或完全删除它们以解决路由冲突。

public class SmartlingController : BaseApiController {
    //POST api/smartling/ProcessSmartlingTranslation
    [Route("api/smartling/ProcessSmartlingTranslation")]
    [VersionedRoute("api/smartling/ProcessSmartlingTranslation", 1)]
    [ResponseType(typeof(HttpResponseMessage))]
    [HttpPost]
    public IHttpActionResult ProcessSmartlingTranslation(HttpRequestMessage request)  {
       //some business logic
    }
}

public class CommentsController : BaseApiController {
    //POST api/comments/GetAndPostBlogComments
    [Route("api/comments/GetAndPostBlogComments")]
    [VersionedRoute("api/comments/GetAndPostBlogComments", 1)]
    [ResponseType(typeof(HttpResponseMessage))]
    [HttpPost]
    public IHttpActionResult GetAndPostBlogComments([FromBody] BlogAndStoryComment comment) {
       //some business logic
    }

    //POST api/comments/GetAndPostStoryComments
    [Route("api/comments/GetAndPostStoryComments")]
    [VersionedRoute("api/comments/GetAndPostStoryComments", 1)]
    [ResponseType(typeof(HttpResponseMessage))]
    [HttpPost]
    public IHttpActionResult GetAndPostStoryComments([FromBody] BlogAndStoryComment comment) {
       //some business logic
    }
}
