重定向到操作 [HttpPost] 返回"resource not found"错误

Question

我有一个相当简单的项目，即使用Ninject与ASP MVC 4和实体框架。我添加了一个基于视图的编辑并创建Action Result，没有问题。但是删除Action Result不起作用。

该视图是基于实体的Ienumrable，具有简单的ActionLink

@Html.ActionLink("Delete", "Delete_Client", new { item.ClientId }) 

控制器也很简单。

[HttpPost]
    public ActionResult Delete_Client(int id)
    {
        Client deleteClient = repository.DeleteClient(id);
        if (deleteClient != null)
        {
            TempData["message"] = string.Format("{0} was deleted.", deleteClient.Name);
        }
        return RedirectToAction("Admin_Client_List");
    }

这通过iinterface

与模型进行交互

 Client DeleteClient(int id);

和实体框架

 public Client DeleteClient(int id)
    {
        Client dbEntry = context.Clients.Find(id);
        if (dbEntry != null)
        {
            context.Clients.Remove(dbEntry);
            context.SaveChanges();
        }
        return dbEntry;
    }

错误是

找不到资源。

这很令人困惑，因为我觉得我不了解框架的非常基本的原则。据我了解，这意味着客户控制器没有相应的动作重点。但是还有。该教程正在通过建议删除操作应为 idempotent ，因此仅包含 [HTTPPPOST] 。

URI看起来像

/Client/Delete_Client?ClientId=12

我认为也许需要看起来像

/Client/Delete_Client/12

但是这不起作用。

更新了admin_client_list.cshtml

的请求

@model IEnumerable<Project.Domain.Entities.Client>
@{
    ViewBag.Title = "Client List";
    ViewBag.Icon = "entypo-layout";
    ViewBag.ClientActive = "active";
    Layout = "~/Views/Shared/_AdminLayout.cshtml";

Answer 1

尝试

@Html.ActionLink("Delete", "Delete_Client", null, new { id = item.ClientId })

您必须删除[httppost]，这是get request

Answer 2

使用以下代码：

@Html.ActionLink("Delete", "Delete_Client", new { id = item.ClientId }) 

[HttpPost]
public ActionResult Delete_Client(int id)
{
    Client deleteClient = repository.DeleteClient(id);
    if (deleteClient != null)
    {
        TempData["message"] = string.Format("{0} was deleted.", deleteClient.Name);
    }
    return RedirectToAction("Admin_Client_List");
}

Answer 3

更改您的代码

@Html.ActionLink("Delete", "Delete_Client", new { item.ClientId }) 

to

@Html.ActionLink("Delete", "Delete_Client", new { id = item.ClientId })
