如何使用自定义错误并保留响应代码
本文关键字:保留 响应 代码 错误 何使用 自定义 | 更新日期: 2023-09-27 18:34:33
在我的web.config吹气中,你可以看到redirectMode="ResponseRewrite"。我读到这是我保留状态代码所需要的。不幸的是,一旦我把它放进去,我就会得到:
"处理您的请求时发生异常。此外,在执行第一个异常的自定义错误页时发生了另一个异常。请求已终止。
省略此变量成功地将我重定向到 ~/Error/Index.cshtml,但响应为 200。任何方向将不胜感激,谢谢。
<system.web>
<compilation debug="true" targetFramework="4.5" />
<customErrors mode="On" redirectMode="ResponseRewrite" defaultRedirect="~/Error/Index">
<error statusCode="404" redirect="~/Error/Index"/>
<error statusCode="500" redirect="~/Error/Index"/>
</customErrors>
<httpRuntime targetFramework="4.5" />
</system.web>
<system.webServer>
<httpErrors errorMode="Custom" existingResponse="Auto" defaultResponseMode="ExecuteURL">
<remove statusCode="403"/>
<remove statusCode="404"/>
<remove statusCode="500"/>
<error statusCode="403" path="~/Error/Index" responseMode="File"/>
<error statusCode="404" path="~/Error/Index" responseMode="File"/>
<error statusCode="500" path="~/Error/Index" responseMode="File"/>
</httpErrors>
</system.webServer>
在我的过滤器配置中.cs:
public class FilterConfig
{
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
// does this conflict?
filters.Add(new HandleErrorAttribute());
}
}
不记得我在哪里看到过这段代码,或者我更改了什么,但它在我的 MVC Web 应用程序中工作正常
网络.config
<system.web>
<compilation debug="true" targetFramework="4.5.1" />
<httpRuntime targetFramework="4.5.1" />
<customErrors mode="Off" />
</system.web>
全球.aspx
protected void Application_EndRequest(Object sender, EventArgs e)
{
ErrorConfig.Handle(Context);
}
错误配置.cs
namespace Web.UI.Models.Errors
{
public static class ErrorConfig
{
public static void Handle(HttpContext context)
{
switch (context.Response.StatusCode)
{
case 401:
Show(context, 401);
break;
case 404:
Show(context, 404);
break;
case 500:
Show(context, 500);
break;
}
}
//TODO uncomment 500 error
static void Show(HttpContext context, Int32 code)
{
context.Response.Clear();
var w = new HttpContextWrapper(context);
var c = new ErrorController() as IController;
var rd = new RouteData();
rd.Values["controller"] = "Error";
rd.Values["action"] = "Index";
rd.Values["id"] = code.ToString(CultureInfo.InvariantCulture);
c.Execute(new RequestContext(w, rd));
}
}
}
错误控制器
public class ErrorController : Controller
{
// GET: Error
[HttpGet]
public ViewResult Index(Int32? id)
{
var statusCode = id.HasValue ? id.Value : 500;
var error = new HandleErrorInfo(new Exception("An exception with error " + statusCode + " occurred!"), "Error", "Index");
int errorCode = statusCode;
ViewBag.error = errorCode;
return View("Error");
}
}
错误视图模型
namespace Web.UI.Models.Errors
{
public class ErrorViewModel
{
public string DisplayErrorMessage { get; set; }
public string DisplayErrorPageTitle { get; set; }
}
}
然后在共享文件夹错误页面中添加
@model Web.UI.Models.Errors.ErrorViewModel
@{
int errorCode = Convert.ToInt32(@ViewBag.error);
switch (errorCode)
{
case 404:
ViewBag.Title = "404 Page Not Found";
Html.RenderPartial("~/Views/Shared/ErrorPages/HttpError404.cshtml");
break;
case 500:
ViewBag.Title = "Error Occurred";
Html.RenderPartial("~/Views/Shared/_Error.cshtml");
break;
default:
ViewBag.Title = @Model.DisplayErrorPageTitle;
Html.RenderPartial("~/Views/Shared/ErrorPages/HttpNoResultsFound.cshtml");
break;
}
}
上面返回页面未找到的 404 状态和错误 500 的状态,希望有帮助
