SharePoint 列表权限控制

一提到sharepoint 我相信权限控制一定会是一个很重要的话题,尤其是对列表的权限控制,创建、修改、查看权限。其实网上这方面的资料已经很多了,尤其是以下2篇文章,后来索性把CodeArt_PermissionEx的源代码下载下来,然后仔细阅读了以下。

利用开源SharePoint Permission Extension插件对SharePoint 的列表进行权限控制!

通过代码解决SharePoint列表视图权限分配问题

要想完全明白源码设计的原理 建议大家先阅读再议WSS RenderingTemplate 对sharepoint模板覆盖有一个简单的了解。我把CodeArt_PermissionEx仔细阅读了一下并且修改了里面的一些代码(个人觉得原作者C#基本功一般,sharepoint方面还是不错,我这里修改的是VS2013版的源码)。修改后部署到sharepoint2013上如图:

SharePoint 列表权限控制

内容内型权限设计如图:

SharePoint 列表权限控制

这里的PersonType是一个自定义内容内型,每一个内型这里有一个人员和组的权限控制,主要控制user是否可以新建记录,比如user不在PersonType内容内型人员和组里面,那么这个user将不能创建记录,没有权限的user进入后看到的结果如图:

SharePoint 列表权限控制

看到这里的新建项目变为不可用了。

这里说说查找权限的方式,首先我们需要的我们的设置保存起来,

1)根据我们的类容类型来找权限设置,如果没有任何权限设置那么我们就直接返回true;

2)如果当前用户是管理员用户直接返回true;

3)在指定的人员里面查找当前user是否存在,存在返回true;

4)指定的组里面是否包含当前user,存在返回true;否则返回false

相关代码如下:

 public bool CheckRight(SPUser user, string contentTypeName)
{
ContentTypeCreateSetting set = this.GetContentTypeCreateSetting(contentTypeName); if (set == null)
return true; return set.CanCreate(user);
}
public bool CanCreate(SPUser currentUser)
{
if (currentUser != null && currentUser.IsSiteAdmin) return true; if (String.IsNullOrEmpty(this.SpecialAccounts) && String.IsNullOrEmpty(this.SpecialGroups))
return true; if (currentUser == null)
{
return false;
} bool inAccounts = this.IsInSpecialAccounts(currentUser.LoginName); if (inAccounts)
return true; return this.IsInSpecialGroups(currentUser);
}
}

主要原理是新建列表数据默认用到的是NewMenu类,这里我们开发一个带有权限控制的子类NewMenuWithPermission,主要代码如下:

   public class NewMenuWithPermission : NewMenu
{ private ListContentTypesCreateSetting _setting;
bool _settingExist = true ; bool UserHaveRight(string cName)
{
if (!_settingExist)
return true; if (_setting == null)
{
_setting = ListContentTypesCreateSetting.GeSetting(base.List);
_settingExist = _setting != null;
} if (_setting == null)
return true ; return _setting.CheckRight(SPContext.Current.Web.CurrentUser, cName); //return true;
} public override MenuItemTemplate AddMenuItem(string id, string displayName, string imageUrl, string description, string navigateUrl, string onClickScript)
{
MenuItemTemplate m = base.AddMenuItem(id, displayName, imageUrl, description, navigateUrl, onClickScript); m.Visible = this.UserHaveRight(displayName); return m;
} }

如何让sharepoint使用我们这个NewMenuWithPermission类,这里我们需要覆盖sharepoint的DocumentLibraryViewToolBar 和 ViewToolBar模板,相关代码如下:

<SharePoint:RenderingTemplate ID="DocumentLibraryViewToolBar" runat="server">
<Template>
<wssuc:ToolBar CssClass="ms-menutoolbar" EnableViewState="false" id="toolBarTbl" ButtonSeparator="<img src='/_layouts/15/images/blank.gif' alt=''>" RightButtonSeparator=" " runat="server">
<Template_Buttons>
<codeart:NewMenuWithPermission runat="server" AccessKey="<%$Resources:wss,tb_NewMenu_AK%>"/>
<%--<SharePoint:NewMenu ID="NewMenu1" Visible="false" AccessKey="<%$Resources:wss,tb_NewMenu_AK%>" runat="server"/>--%>
<SharePoint:UploadMenu ID="UploadMenu1" AccessKey="<%$Resources:wss,tb_UploadMenu_AK%>" runat="server"/>
<SharePoint:ActionsMenu ID="ActionsMenu1" AccessKey="<%$Resources:wss,tb_ActionsMenu_AK%>" runat="server"/>
<SharePoint:SettingsMenu ID="SettingsMenu1" AccessKey="<%$Resources:wss,tb_SettingsMenu_AK%>" runat="server"/>
</Template_Buttons>
<Template_RightButtons>
<SharePoint:PagingButton ID="PagingButton1" runat="server"/>
<SharePoint:ListViewSelector ID="ListViewSelector1" runat="server"/>
</Template_RightButtons>
</wssuc:ToolBar>
</Template>
</SharePoint:RenderingTemplate> <SharePoint:RenderingTemplate ID="ViewToolBar" runat="server">
<Template>
<wssuc:ToolBar CssClass="ms-menutoolbar" EnableViewState="false" id="toolBarTbl" ButtonSeparator="<img src='/_layouts/15/images/blank.gif' alt=''>" RightButtonSeparator=" " runat="server">
<Template_Buttons>
<codeart:NewMenuWithPermission runat="server" AccessKey="<%$Resources:wss,tb_NewMenu_AK%>"/>
<%--<SharePoint:NewMenu AccessKey="<%$Resources:wss,tb_NewMenu_AK%>" runat="server" />--%>
<SharePoint:ActionsMenu AccessKey="<%$Resources:wss,tb_ActionsMenu_AK%>" runat="server" />
<SharePoint:SettingsMenu AccessKey="<%$Resources:wss,tb_SettingsMenu_AK%>" runat="server" />
</Template_Buttons>
<Template_RightButtons>
<SharePoint:PagingButton runat="server"/>
<SharePoint:ListViewSelector runat="server"/>
</Template_RightButtons>
</wssuc:ToolBar>
</Template>
</SharePoint:RenderingTemplate>

现在我们来查看view的权限设计

SharePoint 列表权限控制

没有权限的人访问时运行结果如下:

SharePoint 列表权限控制

这里的view权限查找方式和控制方式与上面内容内型权限控制都是一样的,下面提到的字段权限设计也是一样的原理。只是这里我们需要开发一个PermissionListViewSelector类来扩展默认的ViewSelectorMenu类,实现代码如下:

 public class PermissionListViewSelector : ViewSelectorMenu // Microsoft.SharePoint.WebControls.ListViewSelector
{
protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e); //if (!this.Context.User.Identity.IsAuthenticated)//for anonymous access
//{
// return;
//} var currentUser = base.Web.CurrentUser; if (currentUser != null && currentUser.IsSiteAdmin)
{
return;
} SPList curList = SPContext.Current.List; ListViewPermissionSetting listSetting = ListViewPermissionSetting.GetListSetting(curList);
if (listSetting == null)
{
return;
} if (SPContext.Current.ViewContext == null || SPContext.Current.ViewContext.View == null)
return; SPView currentView = SPContext.Current.ViewContext.View; ViewPermission viewSetting = listSetting.GetByViewID(currentView.ID);
if (viewSetting == null)
return; if (( viewSetting!= null) && (!(viewSetting.CanDisplay(currentUser))))
{
//如果用户没有权限访问当前视图,那么需要计算其有权限访问的试图 if (currentView.DefaultView) //如果访问默认视图而没有权限时,自动转向一个有权限的试图
{
Guid id = listSetting.GetCanDisplayView(currentUser);
if (id == Guid.Empty)
{
SPUtility.TransferToErrorPage(Util.GetResource("Msg_NoViewRight"));
return;
}
else
{
SPView view = curList.Views[id];
SPUtility.Redirect( base.Web.Url +"/"+ view.Url, SPRedirectFlags.Default, this.Context);
return;
}
}
SPUtility.TransferToErrorPage(Util.GetResource("Msg_NoViewRight"));
} //NND, 在2010的07UI模式下这样设置不起作用。
foreach (Control item in base.MenuTemplateControl.Controls)
{
if ((item is MenuItemTemplate))
{
MenuItemTemplate menuItem = (MenuItemTemplate)item; if (menuItem.PermissionsString != "ViewListItems") //修改视图和创建视图菜单
{
menuItem.Visible = false;
continue;
} try
{
SPView tempView = curList.Views[menuItem.Text]; viewSetting = listSetting.GetByViewName(menuItem.Text); if (viewSetting == null)
continue; item.Visible = viewSetting.CanDisplay(currentUser);
}
catch (ArgumentException)
{
}
}
}
} }

如何让sharepoint默认使用我们这个PermissionListViewSelector类了,同样我们需要修改ViewSelector模板

<SharePoint:RenderingTemplate ID="ViewSelector" runat="server">
<Template>
<table border= cellpadding= cellspacing= style='margin-right: 4px'>
<tr>
<td nowrap class="ms-listheaderlabel"><SharePoint:EncodedLiteral ID="EncodedLiteral1" runat="server" text="<%$Resources:wss,view_selector_view%>" EncodeMethod='HtmlEncode'/> </td>
<td nowrap class="ms-viewselector" id="onetViewSelector" onmouseover="this.className='ms-viewselectorhover'" onmouseout="this.className='ms-viewselector'" runat="server">
<codeArt:PermissionListViewSelector MenuAlignment="Right" AlignToParent="true" runat="server" id="ViewSelectorMenu" />
</td>
</tr>
</table>
</Template>
</SharePoint:RenderingTemplate>

最后我们来看看字段权限设置

SharePoint 列表权限控制

这里权限设置分为编辑和查看权限,没有编辑权限的用户如下图:

SharePoint 列表权限控制

结合权限设置的那张图看一看,这里只有Middle Name字段可以编辑,其他所有字段都不能编辑,Middle Name是允许”ALL User“编辑的,所以这里user可以编辑。查看权限也是一样的。

这里我们需要开发一个EditControlListFieldIterator类来扩展默认的ListFieldIterator类,如何让sharepoint来使用我们的这些类,我们需要修改sharepoint的ListForm和FileFormFields模板,相关代码如下:

public class EditControlListFieldIterator : Microsoft.SharePoint.WebControls.ListFieldIterator
{
protected override void CreateChildControls()
{
//if (this.ControlMode == SPControlMode.Display)
//{
// base.CreateChildControls();
// return;
//} SPUser currentUser = SPContext.Current.Web.CurrentUser; if (currentUser != null && currentUser.IsSiteAdmin)
{
base.CreateChildControls();
return;
} ListFieldPermissionSetting listSetting = ListFieldPermissionSetting.GetListSetting(this.List);
if (listSetting == null || listSetting.Count == )
{
base.CreateChildControls();
return;
} //base.CreateChildControls();
this.Controls.Clear();
if (this.ControlTemplate == null)
{
throw new ArgumentException("Could not find ListFieldIterator control template.");
} Type t = typeof(TemplateContainer); PropertyInfo ControlModeProp = t.GetProperty("ControlMode", BindingFlags.Instance | BindingFlags.NonPublic);
PropertyInfo FieldNameProp = t.GetProperty("FieldName", BindingFlags.Instance | BindingFlags.NonPublic); SPUser author = null; if (this.ControlMode == SPControlMode.New)
{
author = base.Web.CurrentUser; for (int i = ; i < base.Fields.Count; i++)
{
SPField field = base.Fields[i]; if (!this.IsFieldExcluded(field))
{
FieldPermission set = listSetting.GetByFieldName(field.InternalName); if (set != null && !set.CanEdit(currentUser, author))
{
continue;
} TemplateContainer child = new TemplateContainer();
this.Controls.Add(child);
FieldNameProp.SetValue(child, field.InternalName, null);
this.ControlTemplate.InstantiateIn(child);
}
} }
else
{
SPFieldUserValue authorFieldValue = new SPFieldUserValue(base.Web, "" + this.ListItem["Author"]);
author = authorFieldValue.User; for (int i = ; i < base.Fields.Count; i++)
{
SPField field = base.Fields[i]; if (!this.IsFieldExcluded(field))
{
SPControlMode thisMode = this.ControlMode; FieldPermission set = listSetting.GetByFieldName(field.InternalName); if (set != null )
{
if (!set.CanEdit(currentUser, author))
{
if (set.CanDisplay(currentUser, author))
thisMode = SPControlMode.Display;
else
continue;
}
} TemplateContainer child = new TemplateContainer();
this.Controls.Add(child);
FieldNameProp.SetValue(child, field.InternalName, null);
ControlModeProp.SetValue(child, thisMode , null);
this.ControlTemplate.InstantiateIn(child); }
} } } }

这里我们的权限设置都保存到哪里去了?这里默认是把权限设置的object 序列化为字符串然后保存到一个特定的文档库里面去了的。

SharePoint 列表权限控制

看到这个图,我想大家应该知道这里的权限设置时怎么保存的了吧,每个list内容内型权限设置、试图权限设置、字段权限设置分别对应一个文件。

源码下载

为了回报大家,这里特地分享一个知识点;大家在安装sharepoint2013 和 VS2013是 一定要保持语言版本一致,我以前遇到一个 站点模板创建后无法识别的issue,原因就是这2个语言不一致。中文版的sharepoint只能识别2052下的自定义模板,而英文版的VS2013 默认会发布到一个1033的文件夹下,所以中文版的sharepoint2013 默认是不能识别英文版VS2013创建的站点模板。
