如何在ASP。NET MVC 4

Question

我想要一个显示500、404和403的自定义错误页面

> < li>

在web.config中启用自定义错误，如下所示:

<customErrors mode="On" 
              defaultRedirect="~/Views/Shared/Error.cshtml">

    <error statusCode="403" 
           redirect="~/Views/Shared/UnauthorizedAccess.cshtml" />

    <error statusCode="404" 
           redirect="~/Views/Shared/FileNotFound.cshtml" />

</customErrors>

已将 HandleErrorAttribute 注册为 FilterConfig 类中的全局操作筛选器，如下所示：

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
    filters.Add(new CustomHandleErrorAttribute());
    filters.Add(new AuthorizeAttribute());
}

为上述每条消息创建了一个自定义错误页面。500 的默认版本已经开箱即用。

在每个自定义错误页面视图中声明页面的模型是 System.Web.Mvc.HandleErrorInfo

对于500，它显示自定义错误页面。对其他人来说，情况并非如此。

我错过了什么吗？

当我阅读< code > HandleErrorAttribute 类的< code>OnException方法中的代码时，看起来这并不是显示自定义错误的全部，它只处理500个错误。

我必须执行哪些操作来处理其他错误？

我做了一些比其他发布的解决方案需要更少编码的事情。

首先，在我的web.config，我有以下几点：

xml prettyprint-override"><customErrors mode="On" defaultRedirect="~/ErrorPage/Oops">
   <error redirect="~/ErrorPage/Oops/404" statusCode="404" />
   <error redirect="~/ErrorPage/Oops/500" statusCode="500" />
</customErrors>

和控制器（/控制器/ErrorPageController.cs）包含以下内容：

public class ErrorPageController : Controller
{
    public ActionResult Oops(int id)
    {
        Response.StatusCode = id;

        return View();
    }
}

最后，该视图包含以下内容（为了简单起见，将其分解，但它可以包含：

@{ ViewBag.Title = "Oops! Error Encountered"; }

<section id="Page">
  <div class="col-xs-12 well">
    <table cellspacing="5" cellpadding="3" style="background-color:#fff;width:100%;" class="table-responsive">
      <tbody>
        <tr>
          <td valign="top" align="left" id="tableProps">
            <img width="25" height="33" src="~/Images/PageError.gif" id="pagerrorImg">
          </td>
          <td width="360" valign="middle" align="left" id="tableProps2">
            <h1 style="COLOR: black; FONT: 13pt/15pt verdana" id="errortype"><span id="errorText">@Response.Status</span></h1>
          </td>
        </tr>
        <tr>
          <td width="400" colspan="2" id="tablePropsWidth"><font style="COLOR: black; FONT: 8pt/11pt verdana">Possible causes:</font>
          </td>
        </tr>
        <tr>
          <td width="400" colspan="2" id="tablePropsWidth2">
            <font style="COLOR: black; FONT: 8pt/11pt verdana" id="LID1">

                                <li id="list1">

Answer 2

我做过pablo解决方案，但总是有错误（MVC4）

未找到视图“错误”或其主视图，或者没有视图引擎支持搜索的位置。

要解决这个问题，请删除该行

 filters.Add(new HandleErrorAttribute());

在FilterConfig.cs

Answer 3

我当前的设置（在MVC3上，但我认为它仍然适用）依赖于ErrorController，所以我使用：

<system.web>
    <customErrors mode="On" defaultRedirect="~/Error">
      <error redirect="~/Error/NotFound" statusCode="404" />
    </customErrors>
</system.web>

并且控制器包含以下内容:

public class ErrorController : Controller
{
    public ViewResult Index()
    {
        return View("Error");
    }
    public ViewResult NotFound()
    {
        Response.StatusCode = 404;  //you may want to set this to 200
        return View("NotFound");
    }
}

视图只是您实现它们的方式。不过，我倾向于添加一些逻辑，以显示应用程序处于调试模式时的堆栈跟踪和错误信息。所以Error.cshtml如下所示：

@model System.Web.Mvc.HandleErrorInfo
@{
    Layout = "_Layout.cshtml";
    ViewBag.Title = "Error";
}
<div class="list-header clearfix">
    <span>Error</span>
</div>
<div class="list-sfs-holder">
    <div class="alert alert-error">
        An unexpected error has occurred. Please contact the system administrator.
    </div>
    @if (Model != null && HttpContext.Current.IsDebuggingEnabled)
    {
        <div>
            <p>
                <b>Exception:</b> @Model.Exception.Message<br />
                <b>Controller:</b> @Model.ControllerName<br />
                <b>Action:</b> @Model.ActionName
            </p>
            <div style="overflow:scroll">
                <pre>
                    @Model.Exception.StackTrace
                </pre>
            </div>
        </div>
    }
</div>
