如何使用标准ASP.NET MVC3网站的自定义404和500错误页面？ [英] How to have a custom 404 and 500 error pages with a stock standard ASP.NET MVC3 website?

问题描述

Darin Dimitrov在这里有一个很好的SO答案，但它不适用于我所有的测试条件。

然后，广泛流行的如何在ASP.NET MVC中正确处理404？发布..但这只是触及404错误。

有人可以请说明什么

• 路线


• web.config 设置


• 控制器/操作方法

需要做这个非常简单的事情：（

接受此答案的方案：

• VS2010 - >文件 - >新 - > ASP.NET MVC3项目/ Internet应用程序


• （右键单击解决方案）.. - > U se IIS Express


• 错误页面不能是静态html页面。他们必须是一个页面，我可以像任何其他视图一样传递信息等（例如，一个 ErrorController ）...

和测试路线...

• /首页/索引 - >显示索引页


• /首页 - >显示索引页


• / - >显示索引页


• /首页/关于 - >显示页面


• / asdasd / asdsad / asdas / asddasd / adsad - > 404


• / adsa / asda / asd / asd / asd / asd - > 404


• / asdsadasda - > 404

然后将其添加到 HomeController .cs class ..

  public ActionResult ThrowException（）
 {
抛出新的NotImplementedException（）; 
} 
  

现在..

• / home / throwexception - > 500错误

Cheers：）

BTW，一些这些真实的长途径（上）给出了非常奇怪的错误页面，当使用股票标准 new ASP.NET MVC3 模板

解决方案

我将web.config文件中的customErrors指定为

 < customErrors defaultRedirect =/ Error / GeneralErrormode =On> 
< error statusCode =403redirect =/ Error / 403/> 
< error statusCode =404redirect =/ Error / 404/> 
< error statusCode =500redirect =/ Error / 500/> 
< / customErrors 
  

我在Global.asax中有一条路线，如下所示： / p>

  ///错误页
 /// 
 routes.MapRoute（
Error ，//路由名称
错误/ {errorCode}，//带参数的URL 
 new {controller =Page，action =Error，errorCode = UrlParameter.Optional} 
 ）; 
  

相应的ActionResult执行以下操作，返回相关的自定义错误页面。

  // 
 public ActionResult错误（string errorCode）
 {
 var viewModel = new PageViewModel（）; 
 
 int code = 0; 
 int.TryParse（errorCode，out code）; 
 
开关（代码）
 {
案例403：
 viewModel.HtmlTitleTag = GlobalFunctions.FormatTitleTag（403 Forbidden）; 
 return View（403，viewModel）; 
 case 404：
 viewModel.HtmlTitleTag = GlobalFunctions.FormatTitleTag（404 Page Not Found）; 
 return View（404，viewModel）; 
案例500：
 viewModel.HtmlTitleTag = GlobalFunctions.FormatTitleTag（500 Internal Server Error）; 
 return View（500，viewModel）; 
 default：
 viewModel.HtmlTitleTag = GlobalFunctions.FormatTitleTag（Embarrassing Error）; 
 return View（GeneralError，viewModel）; 
} 
} 
  

这允许我有许多不同的自定义错误页面。这可能不是最好的或最优雅的解决方案，但它肯定对我有用。

I'm trying to have 2 custom error pages in a stock sample ASP.NET MVC3 website.

Darin Dimitrov has a good SO answer here but it's not working for all my test conditions.

Then there is the widely popular How can I properly handle 404s in ASP.NET MVC? post .. but this just touches on a 404 error.

Can someone please explain what

• Routes
• web.config settings
• controllers / action methods

are required to do this very simple thing :(

Scenarios to accept this answer:

• VS2010 -> File -> New -> ASP.NET MVC3 project / Internet Application
• (Right Click on the solution).. -> Use IIS Express
• Error pages cannot be a static html page. They must be a page which I can pass info to, like any other view, etc. (eg. an ErrorController)...

and for the test routes...

• /Home/Index -> shows index page
• /Home -> shows index page
• / -> shows index page
• /Home/About -> shows about page
• /asdasd/asdsad/asdas/asddasd/adsad -> 404
• /adsa/asda/asd/asd/asd/asd -> 404
• /asdsadasda -> 404

then add this to the HomeController.cs class..

public ActionResult ThrowException()
{
    throw new NotImplementedException();
}

and now ..

• /home/throwexception -> 500 error

Cheers :)

BTW, some of those realy long routes (above) give really weird error pages right now, when using the stock standard new ASP.NET MVC3 template

解决方案

I specify customErrors in my web.config file as below;

    <customErrors defaultRedirect="/Error/GeneralError" mode="On">
      <error statusCode="403" redirect="/Error/403" />
      <error statusCode="404" redirect="/Error/404" />
      <error statusCode="500" redirect="/Error/500" />
    </customErrors

I have a route in the Global.asax as below;

            /// Error Pages
            /// 
            routes.MapRoute(
                "Error", // Route name
                "Error/{errorCode}", // URL with parameters
                new { controller = "Page", action = "Error", errorCode= UrlParameter.Optional }
            );

The corresponding ActionResult does the following, which returns the relevant custom error page.

//
        public ActionResult Error(string errorCode)
        {
            var viewModel = new PageViewModel();

            int code = 0;
            int.TryParse(errorCode, out code);

            switch (code)
            {
                case 403:
                    viewModel.HtmlTitleTag = GlobalFunctions.FormatTitleTag("403 Forbidden");
                    return View("403", viewModel);
                case 404:
                    viewModel.HtmlTitleTag = GlobalFunctions.FormatTitleTag("404 Page Not Found");
                    return View("404", viewModel);
                case 500:
                     viewModel.HtmlTitleTag = GlobalFunctions.FormatTitleTag("500 Internal Server Error");
                    return View("500", viewModel);
                default:
                    viewModel.HtmlTitleTag = GlobalFunctions.FormatTitleTag("Embarrassing Error");
                    return View("GeneralError", viewModel);
            }
        }

This allows me to have many different custom error pages. It's maybe not the best or most elegant solution, but it certainly works for me.
