Question

我的网站有问题。直到最近，我的网站登录工作完美。有一天，我不得不对default.aspx（登录站点）和web.config进行一些更改。

突然登录只是每次尝试都成功。我试图解决它，但它根本不会登录。在回滚web.config和新创建的default.aspx之后，它仍然没有用。

我的下一步是检查Authenticate事件。无论我做什么，登录总是被报告为失败，除了我重新启动Web服务器后的第一次。所以我开始检查登录是否为假。如果是这样，我调用Membership.ValidateUser来检查用户是否真的失败了。由于用户几乎从未进行过身份验证，因此Membership.ValidateUser几乎总是会跳转，但只会每隔一次验证一次用户。

看到这一点，我将一些调试信息放入LoginError事件中。如果用户有效，我连续检查了5次（只是为了确保它没有偶发错误）。每一次都很好。

因此，Membership.ValidateUser不在authentiocate事件中工作，但在LoginError事件中。我甚至试图在身份验证事件中两次调用Membership.ValidateUser，但它仍然无法正常工作。

我现在有点迷失了答案。设置SessionID Cookie，登录成功后设置授权cookie。

这是我的登录控件：

                            <tr>

                            <tr>
                                <td align="right" colspan="2">

                            </tr>
                        </table>
                    </td>
                </tr>
            </table>
        </LayoutTemplate>
        <LoginButtonStyle BackColor="White" BorderColor="#507CD1" BorderStyle="Solid"

这是我的控制事件：

        Protected Sub Login1_Authenticate(sender As Object, e As System.Web.UI.WebControls.AuthenticateEventArgs) Handles Login1.Authenticate
    log4net.Config.XmlConfigurator.Configure()

    log.Debug("Login: 1." & e.Authenticated.ToString)

    If e.Authenticated = False Then
        If (Membership.ValidateUser(Login1.UserName.Trim, Login1.Password)) Then
            log.Debug("Login: 2. Is Valid")
            e.Authenticated = True
            FormsAuthentication.SetAuthCookie(Login1.UserName, True)
        Else
            If (Membership.ValidateUser(Login1.UserName.Trim, Login1.Password)) Then
                log.Debug("Login: 3. Is Valid")
                e.Authenticated = True
                FormsAuthentication.SetAuthCookie(Login1.UserName, True)
            Else
                log.Debug("Login: 4. Aint Valid")
                e.Authenticated = False
            End If
        End If
    End If

    log.Debug("Login: 5. End")
End Sub

Protected Sub Login1_LoginError(sender As Object, e As System.EventArgs) Handles Login1.LoginError
    log4net.Config.XmlConfigurator.Configure()

    log.Debug("Loginerror: 1. Entry")

    Dim a As Integer = 1

    Dim user1 As New BenutzerVerwaltung.clsUser("admin")
    log.Debug("Loginerror: 2. User1 admin: " & user1.UserName)

    Dim user2 As MembershipUser = Membership.GetUser("admin")
    log.Debug("Loginerror: 3. User2 admin: " & user2.UserName)

    If (Membership.ValidateUser(Login1.UserName.Trim, Login1.Password)) Then
        log.Debug("Loginerror: 4. Is Valid, Username: " & Login1.UserName.Trim)
    Else
        log.Debug("Loginerror: 5. Aint Valid, username: " & Login1.UserName.Trim)
    End If


    If (Membership.ValidateUser(Login1.UserName.Trim, Login1.Password)) Then

        log.Debug("Loginerror: 8. Is Valid, Username: " & Login1.UserName.Trim)
    Else
        log.Debug("Loginerror: 9. Aint Valid, username: " & Login1.UserName.Trim)
    End If


    If (Membership.ValidateUser(Login1.UserName.Trim, Login1.Password)) Then
        log.Debug("Loginerror: 10. Is Valid, Username: " & Login1.UserName.Trim)
    Else
        log.Debug("Loginerror: 11. Aint Valid, username: " & Login1.UserName.Trim)
    End If


    If (Membership.ValidateUser(Login1.UserName.Trim, Login1.Password)) Then
        log.Debug("Loginerror: 12. Is Valid, Username: " & Login1.UserName.Trim)
    Else
        log.Debug("Loginerror: 13. Aint Valid, username: " & Login1.UserName.Trim)
    End If

End Sub

不幸的是，我无法解决此问题，也没能确定我的线程。

因此，我必须做一些工作才能使我的网站再次正常工作。登录失败时，我检查用户是否存在于数据库中。如果是这种情况，那么我将授权用户并设置登录Cookies。

          If e.Authenticated = False Then
            'Init Base User, check if System works
            Try
                user1 = New BenutzerVerwaltung.clsUser()
            Catch ex As Exception
                showMessage("Loginfehler: Basis Benutzer")
                Exit Sub
            End Try

            'Check if User exists
            Try
                user1.loadUser(Login1.UserName.Trim)
            Catch ex As Exception
                showMessage("LoginFehler: Benutzer Ini")
                Exit Sub
            End Try

            Try
                'Manually Validate user and set Authentication Cookies.
                If (Membership.ValidateUser(Login1.UserName.Trim, Login1.Password)) Then
                    e.Authenticated = True
                    FormsAuthentication.SetAuthCookie(Login1.UserName, True)
                Else
                    e.Authenticated = False
                End If
            Catch ex As Exception
                showMessage("LoginFehler: MB-Framework")
                Exit Sub
            End Try

          End If

首次登录后，ASP.Net登录控件无法进行身份验证
