將應用程序從本地計算機移動到Web服務器時出現錯誤。 (我沒有得到我的本地主機上的錯誤)將ASP.NET應用程序部署到Web服務器時出現問題
拋出異常的代碼如下:
Dim sSQL As String
Dim strXSLFile As String
sSQL = "<?xml version=""1.0"" ?>"
sSQL += "<ROOT xmlns:sql=""urn:schemas-microsoft-com:xml-sql"">"
sSQL += "<sql:header>"
sSQL += "<sql:param name='uid'/>"
sSQL += "<sql:param name='pwd'/>"
sSQL += "</sql:header>"
sSQL += "<SESSION>"
sSQL += "<LANG>" & lang & "</LANG>"
sSQL += "<SSN>" & Session.SessionID & "</SSN>"
sSQL += "</SESSION>"
sSQL += "<sql:query>exec objSession_login @uid,@pwd</sql:query>"
sSQL += "</ROOT>"
Dim myxml As New XmlDocument
Try
Using conn As SqlConnection = CustomClass.Data.SqlConnectionProvider.Create()
Dim cmd As SqlXmlCommand
cmd = New SqlXmlCommand(conn.ConnectionString & ";Provider=SQLOLEDB.1;")
cmd.CommandType = SqlXmlCommandType.Template
cmd.CommandText = sSQL
Dim paramUid As SqlXmlParameter = cmd.CreateParameter()
paramUid.Name = "@uid"
paramUid.Value = username
Dim paramPwd As SqlXmlParameter = cmd.CreateParameter()
paramPwd.Name = "@pwd"
paramPwd.Value = password
Dim oXR As XmlReader = cmd.ExecuteXmlReader() ' Problem is here
myxml.Load(oXR)
End Using
strXSLFile = "xsl/Dialogue.login.xsl"
Dim mytransform As New XslTransform
Dim myreader As XmlReader
Dim myresolver As XmlResolver
Dim xpDoc As New XPathDocument(New XmlNodeReader(myxml))
mytransform.Load(Current.Request.PhysicalApplicationPath & strXSLFile)
myreader = mytransform.Transform(xpDoc, Nothing, myresolver)
myxml.Load(myreader)
mytransform = Nothing
myreader = Nothing
myresolver = Nothing
xpDoc = Nothing
xmlloaddoc = myxml
Catch ex As Exception
LogWriter.CriticalError(ex, "User Login - Exception Thrown: " & ex.Message)
Err.Raise(Number:=Err.Number, Description:=ex.StackTrace)
End Try
被拋出異常的具體線路是:昏暗OXR作爲的XmlReader = CMD .ExecuteXmlReader()
的日誌信息顯示下面的例外:
異常#1:
用戶登錄 - 異常拋出:必須將SQLOLEDB或SQLNCLI指定爲數據提供者。「 Microsoft.Data.SqlXml.SqlXmlException:必須將SQLOLEDB或SQLNCLI指定爲數據提供者。 ---> System.Runtime.InteropServices.COMException:必須將SQLOLEDB或SQLNCLI指定爲數據提供者。在Microsoft.Data.SqlXml.Common.UnsafeNativeMethods.ISQLXMLCommandManagedInterface.ExecuteToOutputStream()在Microsoft.Data.SqlXml.SqlXmlCommand.innerExecute(流strm)---結束內部異常堆棧跟蹤---在Microsoft.Data.SqlXml.SqlXmlCommand .ExecuteStream()在Microsoft.Data.SqlXml.SqlXmlCommand.ExecuteXmlReader()在dialogue.login.UserLogin(字符串username,字符串密碼,字符串郎)
異常#2:
「用戶登錄 - 異常拋出:異常來自HRESULT:0x80040E14「 Microsoft.Data.SqlXml.SqlXmlException:從HRESULT異常:0x80040E14 ---> System.Runtime.InteropServices.COMException :從HRESULT異常:0x80040E14在Microsoft.Data.SqlXml.Common.UnsafeNativeMethods.ISQLXMLCommandManagedInterface.ExecuteToOutputStream()在Microsoft.Data.SqlXml.SqlXmlCommand.innerExecute(流strm)---結束內部異常堆棧跟蹤---在微軟.Data.SqlXml.SqlXmlCommand.ExecuteStream()在Microsoft.Data.SqlXml.SqlXmlCommand.ExecuteXmlReader()在dialogue.login.UserLogin(字符串username,字符串密碼,字符串郎)
第一例外的是第一個使用SQLOLEDB.1作爲我的提供者的錯誤,我開始玩弄不同的提供者並得到第二個異常。
任何想法?
是的,它是目前安裝在我們的服務器上,我們正在使用IIS6.0,問題仍然存在。 – Brandon
