Question

在CardsController中，我有两个post方法，如下所示。我尝试使用/ api / cards / card或/ api / cards / cardlist并获取异常消息，例如

＆＃34;找到了与请求匹配的多个操作： \ r \ nSystem.Net.Http.HttpResponseMessage类型的PostValue（卡） WebApiService.Controllers.CardsController \ r \ nSystem.Net.Http.HttpResponseMessage 类型上的PostValue（CardList） WebApiService.Controllers.CardsController＆＃34;，＆＃34; ExceptionType＆＃34;：＆＃34; System.InvalidOperationException＆＃34;，＆＃34; StackTrace＆＃34;：＆＃34;在 System.Web.Http.Controllers.ApiControllerActionSelector.ActionSelectorCacheItem.SelectAction（HttpControllerContext controllerContext）\ r \ n at System.Web.Http.Controllers.ApiControllerActionSelector.SelectAction（HttpControllerContext controllerContext）\ r \ n at System.Web.Http.ApiController.ExecuteAsync（HttpControllerContext controllerContext，CancellationToken cancellationToken）\ r \ n at System.Web.Http.Dispatcher.HttpControllerDispatcher.SendAsyncInternal（HttpRequestMessage 请求，取消语音取消语言）\ r \ n at System.Web.Http.Dispatcher.HttpControllerDispatcher.SendAsync（HttpRequestMessage 请求，取消语音取消语言）＆＃34;

<HttpPost()>
<ActionName("card")>
Public Function PostValue(<FromBody()> ByVal value As Card_REQ.Card) As HttpResponseMessage

<HttpPost()>
<ActionName("cardlist")>
Public Function PostValue(<FromBody()> ByVal value As Cards_REQ.CardList) As HttpResponseMessage

在Web.Config配置如下。

config.Routes.MapHttpRoute( _
        name:="DefaultApi", _
        routeTemplate:="api/{controller}/{id}", _
        defaults:=New With {.id = RouteParameter.Optional} _
    )

    config.Routes.MapHttpRoute( _
       name:="DefaultApiWithAction", _
       routeTemplate:="api/{controller}/{action}/{id}", _
       defaults:=New With {.id = RouteParameter.Optional} _
   )

Answer 1

更改Web.Config并首先放置具有更多参数的路径

 config.Routes.MapHttpRoute( _
       name:="DefaultApiWithAction", _
       routeTemplate:="api/{controller}/{action}/{id}", _
       defaults:=New With {.id = RouteParameter.Optional} _
   )

config.Routes.MapHttpRoute( _
        name:="DefaultApi", _
        routeTemplate:="api/{controller}/{id}", _
        defaults:=New With {.id = RouteParameter.Optional} _
    )

与URL匹配的第一个模式将是处理请求的操作。 Check Here
