Question

我有一个ASP.NET MVC 3应用程序。我正在尝试实现http://www.slideshare.net/calamitas/restful-best-practices处找到的路由标准。我正在使用幻灯片15和17作为参考。据我所知，这个幻灯片是关于RAILS的。但是，这种语法似乎更清晰，更自然。这就是我想要使用它的原因。

我已在控制器中成功实现了索引和显示操作。但是，我在创建和更新操作时遇到问题。此时，当我引用其中任何一个时，我收到404.目前，我的控制器看起来像这样：

public class OrdersController : Controller
{
    // GET: /Orders/
    public ActionResult Index()
    {
        var results = new[] {
            new {id=1, price=1.23, quantity=2}
        };
        return Json(results, JsonRequestBehavior.AllowGet);
    }

    //
    // GET: /Orders/{orderID}
    public ActionResult Show(int id)
    {
        string result = "order:" + id;
        return Json(result, JsonRequestBehavior.AllowGet);
    }

    //
    // POST: /Orders/{order}
    [HttpPost]
    public ActionResult Create(object order)
    {
        var message = "The order was successfully created!";
        return Json(message);
    }

    //
    // PUT: /Orders/{orderID}
    [HttpPut]
    public ActionResult Update(object orderID)
    {
        var message = "The order was successfully updated!";
        return Json(message);
    }
}

当我注册路线时，我使用以下内容：

context.MapRoute(
    "OrderList",
    "Orders",
    new { action = "Index", controller="Orders" }
);

context.MapRoute(
    "Order",
    "Orders/{id}",
    new { action = "Show", controller = "Orders", id="" }
);

context.MapRoute(
    "InsertOrder",
    "Orders",
    new { action = "Create", controller = "Orders" }
);

context.MapRoute(
    "UpdateOrder",
    "Orders/{orderID}",
    new { action = "Update", controller = "Orders", orderID = "" }
);

我正在尝试通过JQuery创建和更新。当我使用以下内容时：

// Update
var order = getOrder();
$.ajax({
    url: "/orders",
    type: "put",
    data: JSON.stringify(order),
    contentType: "application/json",
    success: function (result) {
        alert(result);
    },
    error: function () {
        alert("There was a problem.");
    }
});


// Create
var order = getOrder();
$.ajax({
    url: "/orders",
    type: "post",
    data: JSON.stringify(order),
    contentType: "application/json",
    success: function (result) {
        alert(result);
    },
    error: function () {
        alert("There was a problem.");
    }
});

我做错了什么？因为它是404，我倾向于认为这是一个不正确的路由。我认为可能存在冲突，但我不知道如何证明或纠正这一点。同时，我不确定我是否在我的jQuery中正确设置了data属性。感谢您提供任何帮助。

我认为你只需要下一个MapRoutes：

routes.MapRoute(
    "OrdersIndex", // Route name
    "{controller}", // URL with parameters
    new {
            controller = "Orders", 
            action = "Index" 
        } // Parameter defaults
);
routes.MapRoute(
    "OrdersCrud", // Route name
    "{controller}/{id}", // URL with parameters
    new { 
            controller = "Orders", 
            action = "Crud"
        } // Parameter defaults
);

然后在你的控制器类中你需要这样的东西：

public class OrdersController : Controller
{
    // GET: /Orders/
    [HttpGet] //GET is by default
    public ActionResult Index()
    {
        var results = new[] {
            new {id=1, price=1.23, quantity=2}
        };
        return Json(results, JsonRequestBehavior.AllowGet);
    }
    //
    // POST: /Orders/
    [HttpPost]
    public ActionResult Index(object order)
    {   //Create
        var message = "The order was successfully created!";
        return Json(message);
    }

    //
    // GET: /Orders/{orderID} 
    [HttpGet]//GET is by default
    public ActionResult Crud(int id)
    {   //Show
        string result = "order:" + id;
        return Json(result, JsonRequestBehavior.AllowGet);
    }

    //
    // PUT: /Orders/{orderID}
    [HttpPut]
    public ActionResult Crud(object orderWithIDProperty)
    {   //Update
        var message = "The order was successfully updated!";
        return Json(message);
    }

    //
    // DELETE: /Orders/{orderID}
    [HttpDelete]
    public ActionResult Crud(int id)
    {   //Delete
        var message = "The order was successfully deleted!";
        return Json(message);
    }
}

请注意，您无需明确指定[HttpGet]属性，如此link中所述。
