我的ajax在.net mvc 4中调用了错误的方法,我无法弄清楚原因。
我的阿贾克斯:
function addItem(id, ammount) {
$.ajax({
url: "/Shoppingcart/AddItem?id="+id+"&ammount="+ammount,
type: "post",
cache: false,
success: function (result) {
alert("SUCCESS!!!");
},
error: function (textStatus, errorThrown) {
window.console.log(textStatus, errorThrown);
}
});
}
我的mvc控制器:
public class ShoppingcartController : Controller
{
//
// GET: /Shoppingcart/
public ActionResult Index()
{
// Method 1
}
[HttpPost]
public ActionResult AddItem(int id = -1, int ammount = 0)
{
return Redirect("~/Home");
}
}
我的第一种方法是被ajax调用,这很奇怪,因为我调用了/ Shoppingcart / AddItem 为什么会发生这种情况,我该怎么做才能使它发挥作用?
解决方案: 问题不在于调用方法,而是在路由堆栈中。显然,定义路线的顺序会影响它们的重要性。最具体的路线应始终是要申报的第一条路线。
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Index",
url: "{controller}/{id}",
defaults: new { controller = "Home", action = "Index" },
constraints: new { id = @"\d+" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "ControllerOnly",
url: "{controller}",
defaults: new { controller = "Home", action = "Index", id = 0 }
);
}
答案 0 :(得分:3)
问题在于您的路由,因为配置的路由按顺序匹配。
首先,你应该把更多指定的那些,最后是更通用的那些。
您必须首先使用url: "{controller}"
的最常用路由与网址localhost:1862/Shoppingcart/AddItem?id=18&ammount=1
匹配,并使用action = "Index"
代替操作AddItem
。
要修复它,请将路线订单更改为:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Index",
url: "{controller}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "ControllerOnly",
url: "{controller}",
defaults: new { controller = "Home", action = "Index", id = 0 }
);
要正确设置/Product/18
路由的网址,您需要使用"Index"
上的约束而不是id
来更改UrlParameter.Optional
路由,并且需要放置它在"Default"
路线之前:
routes.MapRoute(
name: "Index",
url: "{controller}/{id}",
defaults: new { controller = "Home", action = "Index" },
constraints: new {id = @"\d+"}
);
