Windows Server 2019 中的 SSRS Sql Server Reporting Server Custom Security 2019 异常

Question

我遇到了与 Windows Server 2019 中的 SSRS（Sql Server Reporting Server）2019 自定义安全异常有关的问题。

SSRS 报告在以前版本的 SQL Server（2016、2014 和 2012）中的 winforms vb.net 代码中运行良好，但在 2019 中却不行。

使用 Vb.net Winforms 源代码运行报告并将 WebRequest 发送到 SSRS 服务器，其中包含必要的详细信息，如服务器 URL、用户名、密码、DBName 等，使用 webResponse 返回响应需要为用户获取身份验证 cookie

由于 sqlAuthCookie 为空而出现错误，由于未启用自定义安全异常也出现错误

任何解决方案/帮助都将不胜感激

附加从 vb.net 发送并从 SSRS 服务器获取响应的代码片段。

VB.NET Code
Protected Overrides Function GetWebResponse(ByVal request As WebRequest) As WebResponse
        Dim response As WebResponse = MyBase.GetWebResponse(request)
        Dim cookieName As String = response.Headers("RSAuthenticationHeader")
        ' If the response contains an auth header, store the cookie
        If Not (cookieName Is Nothing) Then
            Dim webResponse As HttpWebResponse = CType(response, HttpWebResponse)
            Dim authCookie As Cookie = webResponse.Cookies(cookieName)
            ' If the auth cookie is null, throw an exception
            If authCookie Is Nothing Then
                Throw New Exception("Unable to generate report - the Reporting Services Custom Security Extension is expected to be enabled in XB")
            End If
            ' otherwise save it for this request
            Me.AuthCookie = authCookie
            ' and send it to the client
        End If
        Return response

    End Function

//adding new GetUserInfo method for IAuthenticationExtension2
       public void GetUserInfo(IRSRequestContext requestContext, out IIdentity userIdentity, out IntPtr userId)
       {
           userIdentity = null;
           if (requestContext.User != null)
           {
               userIdentity = requestContext.User;
           }

           // initialize a pointer to the current user id to zero
           userId = IntPtr.Zero;
       }
