如何在ASP中创建自定义错误页面。Net MVC 4

我想为500、404和403显示一个自定义错误页面。以下是我所做的:

Enabled custom errors in the web.config as follows: <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> Registered HandleErrorAttribute as a global action filter in the FilterConfig class as follows: public static void RegisterGlobalFilters(GlobalFilterCollection filters) { filters.Add(new CustomHandleErrorAttribute()); filters.Add(new AuthorizeAttribute()); } Created a custom error page for each of the above messages. The default one for 500 was already available out of the box. Declared in each custom error page view that the model for the page is System.Web.Mvc.HandleErrorInfo

对于500，它显示自定义错误页面。对其他人来说，则不然。

我是不是遗漏了什么?

当我阅读HandleErrorAttribute类的OnException方法中的代码时，它看起来并不是显示自定义错误的全部，而且它只处理500个。

我必须做什么来处理其他错误?

这是我的解决方案。使用[ExportModelStateToTempData] / [ImportModelStateFromTempData]在我看来是不舒服的。

~ Views / Home / Error.cshtml:

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

<h2>Error</h2>
<hr/>

<div style="min-height: 400px;">

    @Html.ValidationMessage("Error")

    <br />
    <br />

    <button onclick="Error_goBack()" class="k-button">Go Back</button>
    <script>
        function Error_goBack() {
            window.history.back()
        }
    </script>

</div>

~ /控制器/ HomeController.sc:

public class HomeController : BaseController
{
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult Error()
    {
        return this.View();
    }

    ...
}

~ /控制器/ BaseController.sc:

public class BaseController : Controller
{
    public BaseController() { }

    protected override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        if (filterContext.Result is ViewResult)
        {
            if (filterContext.Controller.TempData.ContainsKey("Error"))
            {
                var modelState = filterContext.Controller.TempData["Error"] as ModelState;
                filterContext.Controller.ViewData.ModelState.Merge(new ModelStateDictionary() { new KeyValuePair<string, ModelState>("Error", modelState) });
                filterContext.Controller.TempData.Remove("Error");
            }
        }
        if ((filterContext.Result is RedirectResult) || (filterContext.Result is RedirectToRouteResult))
        {
            if (filterContext.Controller.ViewData.ModelState.ContainsKey("Error"))
            {
                filterContext.Controller.TempData["Error"] = filterContext.Controller.ViewData.ModelState["Error"];
            }
        }

        base.OnActionExecuted(filterContext);
    }
}

~ /控制器/ MyController.sc:

public class MyController : BaseController
{
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult Details(int id)
    {
        if (id != 5)
        {
            ModelState.AddModelError("Error", "Specified row does not exist.");
            return RedirectToAction("Error", "Home");
        }
        else
        {
            return View("Specified row exists.");
        }
    }
}

祝你们项目成功;-)

其他回答

我目前的设置(在MVC3上，但我认为它仍然适用)依赖于有一个ErrorController，所以我使用:

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

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");
    }
}

视图就是你实现它们的方式。不过，我倾向于添加一些逻辑，以便在应用程序处于调试模式时显示堆栈跟踪和错误信息。所以错误。CSHTML看起来像这样:

@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>

我建议使用Global.asax.cs文件。

 protected void Application_Error(Object sender, EventArgs e)
{
    var exception = Server.GetLastError();
    if (exception is HttpUnhandledException)
    {
        Server.Transfer("~/Error.aspx");
    }
    if (exception != null)
    {
        Server.Transfer("~/Error.aspx");
    }
    try
    {
        // This is to stop a problem where we were seeing "gibberish" in the
        // chrome and firefox browsers
        HttpApplication app = sender as HttpApplication;
        app.Response.Filter = null;
    }
    catch
    {
    }
}

我做过pablo解决方案，我总是有错误(MVC4)

未找到视图'Error'或其主视图或没有视图引擎支持搜索位置。

要去掉这个，去掉线条

 filters.Add(new HandleErrorAttribute());

在FilterConfig.cs

看来我来晚了，但你最好也看看这个。

在系统中。web用于缓存应用程序中的异常，例如返回HttpNotFound()

  <system.web>
    <customErrors mode="RemoteOnly">
      <error statusCode="404" redirect="/page-not-found" />
      <error statusCode="500" redirect="/internal-server-error" />
    </customErrors>
  </system.web>

在系统中。webServer用于捕获IIS捕获的错误，而这些错误没有进入asp.net框架

 <system.webServer>
    <httpErrors errorMode="DetailedLocalOnly">
      <remove statusCode="404"/>
      <error statusCode="404" path="/page-not-found" responseMode="Redirect"/>
      <remove statusCode="500"/>
      <error statusCode="500" path="/internal-server-error" responseMode="Redirect"/>
  </system.webServer>

在最后一个例子中，如果你担心客户端响应，那么将responseMode="Redirect"更改为responseMode="File"并提供一个静态html文件，因为这个例子将显示一个响应代码为200的友好页面。

我做了一些比其他解决方案需要更少的编码。

首先，在我的网里。配置，我有以下:

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

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

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

        return View();
    }
}

最后，视图包含以下内容(为了简单起见，删除了内容，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"> <hr> <ul> <li id="list1"> <span class="infotext"> <strong>Baptist explanation: </strong>There must be sin in your life. Everyone else opened it fine.<br> </span> </li> <li> <span class="infotext"> <strong>Presbyterian explanation: </strong>It's not God's will for you to open this link.<br> </span> </li> <li> <span class="infotext"> <strong> Word of Faith explanation:</strong> You lack the faith to open this link. Your negative words have prevented you from realizing this link's fulfillment.<br> </span> </li> <li> <span class="infotext"> <strong>Charismatic explanation: </strong>Thou art loosed! Be commanded to OPEN!<br> </span> </li> <li> <span class="infotext"> <strong>Unitarian explanation:</strong> All links are equal, so if this link doesn't work for you, feel free to experiment with other links that might bring you joy and fulfillment.<br> </span> </li> <li> <span class="infotext"> <strong>Buddhist explanation:</strong> .........................<br> </span> </li> <li> <span class="infotext"> <strong>Episcopalian explanation:</strong> Are you saying you have something against homosexuals?<br> </span> </li> <li> <span class="infotext"> <strong>Christian Science explanation: </strong>There really is no link.<br> </span> </li> <li> <span class="infotext"> <strong>Atheist explanation: </strong>The only reason you think this link exists is because you needed to invent it.<br> </span> </li> <li> <span class="infotext"> <strong>Church counselor's explanation:</strong> And what did you feel when the link would not open? </span> </li> </ul> <p> <br> </p> <h2 style="font:8pt/11pt verdana; color:black" id="ietext"> <img width="16" height="16" align="top" src="~/Images/Search.gif"> HTTP @Response.StatusCode - @Response.StatusDescription <br> </h2> </font> </td> </tr> </tbody> </table> </div> </section>

就是这么简单。它可以很容易地扩展，以提供更详细的错误信息，但ELMAH为我处理，statusCode和statusDescription是我通常需要的。
