SharePoint 2010 XsltListViewWebPart -匿名用户拒绝访问外部xsl文件

Question

我正在使用带有外部.xsl文件的XSLTListViewWebPart：

<xlslink>my.xls</xlslink>

有了授权访问，一切正常，但如果我尝试匿名重复此操作，我会得到一个错误：

Error while executing web part: System.UnauthorizedAccessException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
at Microsoft.SharePoint.Library.SPRequest.UpdateWebPartCache(String bstrWebUrl, Boolean bAllUsers, String bstrID, Byte[]& ppsaData, Boolean fOMCall)     
at Microsoft.SharePoint.WebPartPages.SPWebPartManager.CacheWriteInternal(Guid storageKey, Byte[] cacheData, Storage storage, Boolean omCall)     
at Microsoft.SharePoint.WebPartPages.BaseXsltListWebPart.get_CustomizedXsl()

at Microsoft.SharePoint.WebPartPages.DataFormWebPart.GetXslCompiledTransform()     
at Microsoft.SharePoint.WebPartPages.DataFormWebPart.PrepareAndPerformTransform(Boolean bDeferExecuteTransform)

这是SharePoint的bug吗？

Answer 1

这是一个SharePoint错误。SharePoint只做一次转换并缓存它，这是一个缓存问题。有关更多详细信息，请查看此帖子：

Answer 2

我能够通过使用DataFormWebPart而不是ListViewWebPart来解决这个问题。然后可以以同样的方式使用XSLT文件，似乎不存在与缓存相关的问题。
