在局部视图中加载 MVC 错误页面

Question

我有一个错误页面，其布局在大多数情况下都可以正常工作，但是当返回部分视图的控制器中出现错误时，错误页面及其布局将放置在部分视图中。我想这是合乎逻辑的，但我希望将错误页面作为整页加载。如何在不更改所有错误处理的情况下实现这一点。

web.config：

<customErrors mode="On" defaultRedirect="~/Error">
  <error statusCode="500" redirect="~/SystemPages/ErrorPage" />
  <error statusCode="403" redirect="~/SystemPages/FileNotFound" />
  <error statusCode="404" redirect="~/SystemPages/FileNotFound" />
</customErrors>

全球.asax：

Shared Sub RegisterGlobalFilters(ByVal filters As GlobalFilterCollection)
    filters.Add(New HandleErrorAttribute())
End Sub

基础控制器：

Protected Overrides Sub OnException(ByVal filterContext As ExceptionContext)

    If filterContext Is Nothing Then Return

    If TypeOf (filterContext.Exception) Is FaultException Then
        Dim CodeName As String = 
        CType(filterContext.Exception, FaultException).Code.Name
        Dim Message As String = CType(filterContext.Exception, FaultException).Message
        TempData("ErrorMessage") = Message
    Else
        Logging.LogDebugData(HamtaDebugInformation(filterContext.RouteData))
        Logging.WriteExceptionLog(filterContext.Exception)
        TempData("ErrorMessage") = filterContext.Exception.Message
    End If

    Response.Redirect("/SystemPages/ErrorPage")

End Sub

搜索控制器：

   Function GetData() As ActionResult
   ...
   Return PartialView("_Tab", vmData)

错误页面：

@Code
ViewData("Title") = "ErrorPage"
Layout = "~/Views/Shared/_Layout.vbhtml"
End Code

<div id="mainContent" class="oneColumn">
<div class="panel">
    <span class="panelTLC"></span>
    <span class="panelTRC"></span>
    <div id="inputPanel" class="panelContent">
        <div class="modul">
            <div class="modulHead">
                <span class="TLC"></span>
                <span class="TRC"></span>
            </div>
            <div class="modulContent">
                <span class="TLC"></span><span class="TRC"></span>
                <p>@ViewBag.ErrorMessage</p>
                <p>@TempData("ErrorMessage")</p>
                <span class="BLC"></span>
                <span class="BRC"></span>
            </div>
        </div>
    </div>
    <span class="panelBLC"></span><span class="panelBRC"></span>
</div>
</div>

您可以只使用 try catch 块并在 catch 中返回 View() 而不是 PartialView()。

Function GetData() As ActionResult
Try
...
Return PartialView("_Tab", vmData)
Catch ex as Exception
//Handle exception here ( send to error log, etc)
Return View("~/SystemPages/ErrorPage")
End Try

或

web.config：

<customErrors mode="On"/>

基础控制器：

Protected Overrides Sub OnException(ByVal filterContext As ExceptionContext)

    If filterContext Is Nothing Then Return

    Dim Message As String

    If TypeOf (filterContext.Exception) Is FaultException Then
        Dim CodeName As String = 
        CType(filterContext.Exception, FaultException).Code.Name
        Message = CType(filterContext.Exception, FaultException).Message
    Else
        Logging.LogDebugData(HamtaDebugInformation(filterContext.RouteData))
        Logging.WriteExceptionLog(filterContext.Exception)
        Message = filterContext.Exception.Message
    End If

    Response.Redirect(String.Format("~/Error/HttpError/?message={1}", "HttpError", Message))

End Sub

错误控制器：

public class ErrorController : Controller
{
    // GET: /Error/HttpError
    public ActionResult HttpError(string message) {
       return View("ErrorTest", message);
}

介绍如何分别处理每种类型的错误。请记住，您是在 basecontroller 而不是 global.asax 文件中处理异常。如果您能够更改异常处理，那将是更好的方法。
