我有一个MVC4索引页面,其中包含以下链接:
$file = fopen("file.txt", "r");
$subject="Hey";
$txt="Hello...";
while(!feof($file)){
$to = fgets($file);
mail($to,$subject,$txt);
}
fclose($file);
但奇怪的是,两者都变成了指向 CURRENT 路径的超链接(即如果我们在 domain / Euro / 2016/1 都链接到此地址),而不是指向指定的控制器。
RouteConfig 中的一切正常:
@Html.ActionLink("FOO", "Index", "Mil", new { year = String.Empty, id = String.Empty }, null)
@Html.ActionLink("BAR", "Index", "Euro", new { year = String.Empty, id = String.Empty }, null)
控制器/操作存在且工作正常:
EuroController :
routes.MapRoute(
name: "Default",
url: "{controller}/{year}/{id}",
defaults: new { controller = "Home", action = "Index", year = UrlParameter.Optional, id = UrlParameter.Optional }
);
导致这种奇怪行为的原因是什么?
修改
如果我传递年份参数,工作正常:public ActionResult Index(int? year, int? id)
{
...
}
正确指向域/ Mil / 666 。

我可以通过在默认路线之后添加此新路线来使其正常工作。
routes.MapRoute(
name: "Default",
url: "{controller}/{year}/{id}",
defaults: new { controller = "Home", action = "Index", year = "", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "New",
url: "{controller}/{year}",
defaults: new { controller = "Home", action = "Index", year = UrlParameter.Optional }
);
以下所有链接都会产生预期效果:
@Html.ActionLink("Euro 2014", "Index", "Euro", new { year = 2014 }, null)
@Html.ActionLink("Euro 2015", "Index", "Euro", new { year = 2015, id = String.Empty }, null)
@Html.ActionLink("Euro 2016", "Index", "Euro", new { year = DateTime.Now.Year, id = "" }, null)
@Html.ActionLink("Back to Euro", "Index", "Euro", new { year = String.Empty }, null)
