找到多个控制器类型匹配请求 URL

Question

我在路由配置文件中启用了属性路由并且我已经将属性路由声明为

[RoutePrefix("receive-offer")]
public class ReceiveOfferController : Controller
{
    // GET: ReceiveOffer
    [Route("{destination}-{destinationId}")]
    public ActionResult Index(int destinationId)
    {
        return View();
    }
}


public class DestinationController : Controller
{
    [Route("{country}/{product}-{productId}")]
    public ActionResult Destination(string country, string product, int productId)
    {
        return View();
    }

}

以上两个控制器，一个是静态前缀，一个是变量前缀但我发现 Multiple controller types were found that match the URL error from these two controller.

这个路由模式有什么问题。

当属性路由匹配多个路由时会出现这种情况你可以看看这个Multiple controller types were found that match the URL。所以当你输入 domain/receive-offer/new york-1 时，它匹配第一条路线和第二条路线 URL 因为它会将 receive-offer 视为一个国家所以要解决这个问题我们可以使用路线约束指定路线的值，这样您的路线将是

 [RoutePrefix("receive-offer")]
    public class ReceiveOfferController : Controller
    {
        // GET: ReceiveOffer
        [Route("{destination}-{destinationId:int}")]
        public ActionResult Index(int destinationId)
        {
            return View();
        }
    }


    public class DestinationController : Controller
    {
        [Route("{country:alpha}/{product}-{productId:int}")]
        public ActionResult Destination(string country, string product, int productId)
        {
            return View();
        }
     }

因为 destinationId 和 productId 将是 int 类型，而 country 将是 alphabet 但请记住，如果您在国家/地区中添加空格命名该路线将不起作用，因此您必须申请 regax 或者您可以删除国家名称之间的空格，例如 HongKong
