Question

我注意到一些我不喜欢的行为，我想知道这是否正常。

我有一个继承自Mvc.Controller的BaseController，我内部有一个View函数，可以在每个页面加载时触发。

Protected Overrides Function View(ByVal viewName As String, ByVal masterName As String, ByVal model As Object) As System.Web.Mvc.ViewResult


    If Session("UserInfo") Is Nothing AndAlso User.Identity.IsAuthenticated Then
        Try
            ActivityMonitorService.AddActivity(UserService.GetUserByOpenID(HttpContext.User.Identity.Name).ID, _
                                               Utilities.ActivityMonitor.Log.SessionStarted, _
                                               Utilities.DataConverters.IPAddressToNumber(HttpContext.Request.UserHostAddress))
            ActivityMonitorService.SubmitChanges()
        Catch : End Try
        Session("UserInfo") = UserService.GetUserByOpenID(HttpContext.User.Identity.Name)
    End If

End Function

我遇到的问题是如果会话状态关闭，我会在此函数上出现对象引用错误

Function Edit(ByVal id As Integer) As ActionResult
    If DirectCast(Session("UserInfo"), Domain.User).ID = id Then

        Dim user As Domain.User = UserService.GetUserByID(id)
        Return View(user)

    Else
        Response.StatusCode = CInt(HttpStatusCode.NotFound)
        Return RedirectToAction("NotFound", "Error")
    End If
End Function

现在我假设这是因为基函数View实际上是在Return View(user)上启动的。如果这是真的，我将如何连接它以在ActionResult呼叫中发起事件？

如果我把代码放在这里似乎确实有效

Protected Overrides Function CreateActionInvoker() As System.Web.Mvc.IActionInvoker
    If Session("UserInfo") Is Nothing AndAlso User.Identity.IsAuthenticated Then
        Try
            ActivityMonitorService.AddActivity(UserService.GetUserByOpenID(HttpContext.User.Identity.Name).ID, _
                                               Utilities.ActivityMonitor.Log.SessionStarted, _
                                               Utilities.DataConverters.IPAddressToNumber(HttpContext.Request.UserHostAddress))
            ActivityMonitorService.SubmitChanges()
        Catch : End Try
        Session("UserInfo") = UserService.GetUserByOpenID(HttpContext.User.Identity.Name)
    End If
    Return MyBase.CreateActionInvoker()
End Function

这是将会话状态设置为“东西”的正确位置吗？

我打算将此标记为我的编辑

中的解决方案的答案

Protected Overrides Function CreateActionInvoker() As System.Web.Mvc.IActionInvoker
    If Session("UserInfo") Is Nothing AndAlso User.Identity.IsAuthenticated Then
        Try
            ActivityMonitorService.AddActivity(UserService.GetUserByOpenID(HttpContext.User.Identity.Name).ID, _
                                               Utilities.ActivityMonitor.Log.SessionStarted, _
                                               Utilities.DataConverters.IPAddressToNumber(HttpContext.Request.UserHostAddress))
            ActivityMonitorService.SubmitChanges()
        Catch : End Try
        Session("UserInfo") = UserService.GetUserByOpenID(HttpContext.User.Identity.Name)
    End If
    Return MyBase.CreateActionInvoker()
End Function

ASP.NET MVC基本控制器功能在我需要它时不会触发
