创建了一个操作方法，但它仍然给出 "Http 404 error of missing url"

Question

我已经创建了一个表单和一个保存按钮。我还创建了一个操作方法 CREATE，当我们单击 SAVE 按钮时将调用它。我现在想查看模型绑定，但是当我填写表单并单击保存按钮时，它显示以下错误消息。it shows the error message 请参阅附件代码

@using (Html.BeginForm("Create", "Customer"))
            {
                <div class="form-group">
                    @Html.LabelFor(m=>m.Customer.Name)
                    @Html.TextBoxFor(m=>m.Customer.Name, new { @class="form-control"})
                </div>

                <div class="form-group">
                    @Html.LabelFor(m=>m.Customer.BirthDate)
                    @Html.TextBoxFor(m=>m.Customer.BirthDate, new { @class="form-control"})
                </div>

                <div class="checkbox">
                    <label>
                        @Html.CheckBoxFor(m=>m.Customer.IsSubscribedToNewsLetter) Subscribed to Newsletter?
                    </label>
                </div>

                <div class="form-group">
                    @Html.LabelFor(m=>m.Customer.MembershipTypeId)
                   @*List of items*@
                    @Html.DropDownListFor(m=>m.Customer.MembershipTypeId, new SelectList(Model.MembershipTypes,"Id","Name"),"Select",new { @class="form-control"})
                </div>

                <button type="submit" class="btn btn-primary">Save</button>
}

下面是从控制器创建动作的方法

 [HttpPost]
    public ActionResult Create(Customer customer)
    {
        return View();
    }

Answer 1

尝试添加属性路由

[Route("~/customer/create")]
public ActionResult Create(Customer customer)

并在视图顶部添加模型

@model Customer

@using (Html.BeginForm("Create", "Customer", FormMethod.Post)) {

如果您使用的是 Net 4.8 或更早版本，则必须配置属性路由

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute(“{resource}.axd/{*pathInfo}”);
 
    routes.MapMvcAttributeRoutes();
 
    routes.MapRoute(
        name: “Default”,
        url: “{controller}/{action}/{id}”,
        defaults: new { controller = “Home”, action = “Index”, id = UrlParameter.Optional }
    );
}
````

创建了一个操作方法，但它仍然给出 "Http 404 error of missing url"

An action method is created but it still gives the "Http 404 error of missing url"
