ASP.NET - 使用ActionLink时出现404错误

我遇到了错误404,这意味着我缺少某些资源。

我对ASP.NET MVC没有经验,路由是我最常用的地方,虽然这对我来说是无法预料的错误,因为我有所需的控制器+动作。

1 Raport有许多ThrashType记录。它们是单独的表格,但我认为此时并不重要。

问题是我得到了Raport表的正确视图和记录。

当我在视图中悬停链接时,它的格式为{host} / Raport / EditRecords / {string_id}

当我单击视图中的链接(尝试转到EditRecords)时,我收到404错误,这是令人困惑的atm。

       public static void RegisterRoutes(RouteCollection routes)
        {                  
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );


            routes.MapRoute(
            "Home",
            "Edit/{productId}",
            new { controller = "Home", action = "Edit" },
            new { productId = @"\w+" }
            );
        } 

代码如下:

controller EditRaport:

    public ActionResult EditRaport()
    {
       var query = from dbs in db.Raport
                    select dbs;

        return View(query as IEnumerable<Raport>);
    }

控制器EditRecords:

     public ActionResult EditRecords(string id)
    {
        var query = from dbs in db.ThrashType
                    where dbs.raport_id == id
                    select dbs;

        return View(query as IEnumerable<ThrashType>);
    }

查看EditRaport:

@model IEnumerable<WebApplication1.Klasy_Raport.Raport>

@{
    ViewBag.Title = "EditRaport";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Edit Raport</h2>


<table class="table">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.UserFrontInfo.userName)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.creation_time)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.last_modyfication)
        </th>
        <th></th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.UserFrontInfo.userName)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.creation_time)
        </td>       
        <td>
            @Html.DisplayFor(modelItem => item.last_modyfication)
        </td>
        <td>
            @Html.ActionLink("Edit", "EditRecords", new { id=item.raport_id }) 

        </td>
    </tr>
}

</table>

你能不能给我一个关于错误可能在哪里的线索?在这种情况下我真的不理解404。

在@StephenMuecke的帮助下,我了解了问题的原因。 他给了我一个链接,更详细地解释了这个问题: Dots in URL causes 404 with ASP.NET mvc and IIS

事实上,我的身份证像是“12.34.56 00:00:00abcde”。如果您尝试这样做会导致IE错误(404)。

答案是将ID更改为“1234560000000abcde”,这样IE就可以进行处理。

就我而言,这完成了这项工作:

    //remove dots and colons from string
    var datePart = DateTime.Today.ToString().Replace(".", "").Replace(":","");

    //giving string properties and assigning for alias
    var namePart = User.Identity.Name.ToString();

    //removing @blablabl.ab - 12 signs, 13 is for the sake of correct      indexing
    var nameShort = namePart.Remove((namePart.Length)-13, 12);

    //final ID concatenation
    newRaport.raport_id = datePart + nameShort;

谢谢!

     public static void RegisterRoutes(RouteCollection routes)
    {                  
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );


        routes.MapRoute(
        "Home",
        "Edit/{productId}",
        new { controller = "Home", action = "Edit" },
        new { productId = @"\w+" }
        );
    } 

在RegisterRoutes中删除以下路由:

 routes.MapRoute(
        "Home",
        "Edit/{productId}",
        new { controller = "Home", action = "Edit" },
        new { productId = @"\w+" }
        );
