我们有一个Webpart显示与用户的链接。这些可以是listItems，列表或网站。在页面加载中，我们检查用户是否具有访问每个链接所需的权限。如果他们不这样做，链接将不会为他们呈现。我们提供的解决方案可以正常工作，并且链接可以按预期呈现。
我们使用DoesUserHavePermission方法检查权限，该方法可用于列表项，列表和网站。这样可以正常工作，并根据用户权限返回正确的结果。
问题是调用此方法时，即使它可以正常工作，它也会在ULS日志中引发异常。例外的示例如下：

下面是调用diduserhavepermission的代码段：
web.DoesUserHavePermissions(SPContext.Current.Web.CurrentUser.LoginName, SPBasePermissions.ViewPages);
获取网络和调用方法之间的上下文是相同的。我试图提升权限，但没有运气。
我先问一下这里，然后再向Microsoft提出。预先感谢。
