我想将所有401错误重定向到自定义错误页面。我最初在我的web.config中设置了以下条目。
<customErrors defaultRedirect="ErrorPage.aspx" mode="On"> <error statusCode="401" redirect="~/Views/Shared/AccessDenied.aspx" /> </customErrors>
当使用IIS Express时，我收到库存IIS Express 401错误页面。
在不使用IIS Express的情况下，返回空白页。使用Google Chrome的“网络”选项卡检查响应，我看到当页面为空时，标题中返回了401状态
到目前为止我所尝试的是使用this SO answer的建议，因为我使用IIS Express，但无济于事。我已经尝试使用<自定义错误>和< httpErrors>没有运气 – 标准错误或空白页仍然显示。
现在的httpErrors部分看起来像above SO question的the link(我也发现另外一个非常promising answer，但是没有运气 – 空白的回应)
<system.webServer>
<httpErrors errorMode="DetailedLocalOnly" existingResponse="PassThrough" >
<remove statusCode="401" />
<error statusCode="401" path="/Views/Shared/AccessDenied.htm" />
</httpErrors>
<!--
<httpErrors errorMode="Custom"
existingResponse="PassThrough"
defaultResponseMode="ExecuteURL">
<remove statusCode="401" />
<error statusCode="401" path="~/Views/Shared/AccessDenied.htm"
responseMode="File" />
</httpErrors>
-->
</system.webServer>
我甚至修改了applicationhost.config文件并修改了< httpErrors lockAttributes =“allowAbsolutePathsWhenDelegated，defaultPath”>到< httpErrors lockAttributes =“allowAbsolutePathsWhenDelegated”>基于iis.net的信息。在我的努力过程中，我还设法在another SO question中描述了这个错误。
附加信息
以下控制器操作已使用特定用户的Authorize属性进行装饰。
[HttpGet]
[Authorize(Users = "domain\\userXYZ")]
public ActionResult Edit()
{
return GetSettings();
}
[HttpPost]
[Authorize(Users = "domain\\userXYZ")]
public ActionResult Edit(ConfigurationModel model,IList<Shift> shifts)
{
var temp = model;
model.ConfiguredShifts = shifts;
EsgConsole config = new EsgConsole();
config.UpdateConfiguration(model.ToDictionary());
return RedirectToAction("Index");
}
解决方法
我使用这些步骤：
// in Global.asax.cs:
protected void Application_Error(object sender,EventArgs e) {
var ex = Server.GetLastError().GetBaseException();
Server.ClearError();
var routeData = new RouteData();
routeData.Values.Add("controller","Error");
routeData.Values.Add("action","Index");
if (ex.GetType() == typeof(HttpException)) {
var httpException = (HttpException)ex;
var code = httpException.GetHttpCode();
routeData.Values.Add("status",code);
} else {
routeData.Values.Add("status",500);
}
routeData.Values.Add("error",ex);
IController errorController = new Kavand.Web.Controllers.ErrorController();
errorController.Execute(new RequestContext(new HttpContextWrapper(Context),routeData));
}
protected void Application_EndRequest(object sender,EventArgs e) {
if (Context.Response.StatusCode == 401) { // this is important,because the 401 is not an error by default!!!
throw new HttpException(401,"You are not authorised");
}
}
和：
// in Error Controller:
public class ErrorController : Controller {
public ActionResult Index(int status,Exception error) {
Response.StatusCode = status;
return View(status);
}
protected override void Dispose(bool disposing) {
base.Dispose(disposing);
}
}
@* in ~/Views/Error/Index.cshtml: *@
@model Int32
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<title>Kavand | Error</title>
</head>
<body>
<div>
There was an error with your request. The error is:<br />
<p style=" color: Red;">
@switch (Model) {
case 401: {
<span>Your message goes here...</span>
}
break;
case 403: {
<span>Your message goes here...</span>
}
break;
case 404: {
<span>Your message goes here...</span>
}
break;
case 500: {
<span>Your message goes here...</span>
}
break;
//and more cases for more error-codes...
default: {
<span>Unknown error!!!</span>
}
break;
}
</p>
</div>
</body>
</html>
AND – 最后一步：
<!-- in web.config: --> <customErrors mode="Off"/>
