从SharePoint中删除不需要的用户权限

我有一个高级脚本，它设置用户对特定文件夹的访问权限，以便读取某些文件

用户的组被分配到恰好同名的文件夹

然后我创建了一个新视图，将其设置为默认值，并告诉它显示所有不带文件夹的文件

这个脚本已经完美运行了4个月，但是现在有些人想要使用移动视图，我遇到了一个问题。如果用户没有从根目录读取相关文件夹的权限，SharePoints mobile view将不会显示该文件夹

例如，用户设置了以下权限： 根目录上的有限访问权限 对Alpha文件夹的访问受限 对Alpha下文件夹的读取访问权限

我需要这样做，以便用户可以在移动视图中查看

这是我的密码：

找到了。连续4个小时的尝试和错误，但它的工作。希望这对其他人也有帮助。放置在$OpenWeb.GetFolder$path.Item.Update之前

$returnGroups = $OpenWeb.GetFolder($path).Item.RoleAssignments | `
        where {`
         ($_.RoleDefinitionBindings -eq $OpenWeb.RoleDefinitions["Limited Access"]) -and `
         ($_.RoleDefinitionBindings -notcontains $OpenWeb.RoleDefinitions["Read"])`
        };
        if ($returnGroups -not $null)
        {
         foreach ($item in $returnGroups)
         {
          Write-Host "Removing: " $item.Member;
          $OpenWeb.GetFolder($path).Item.RoleAssignments.Remove($spc[$item.Member]);
         }
        }

我知道有一个Item.roleasignments.Remove命令，但我还没有找到一种方法来列出所有当前分配的组，以便循环并删除它们。希望这对你们有帮助！
