通用权限管理系统菜单展示的一个技巧
日期：2014-06-10 浏览次数：20864 次
从这篇文章，希望您能够了解吉日嘎拉通用权限管理系统菜单项配置、缓存及在前台的展示技巧。
项目中使用了吉日嘎拉的通用权限管理系统，几十个子系统均由该权限管理系统管理。
在系统中配置好相关菜单及非菜单项，配置截图：
菜单权限设置截图
通过下拉菜单进入其中的一个子系统
子系统中的菜单项（菜单项表示该项会在前端需要展示出来，用于用户点击的项目），其中的公开表示所有人均可看到该菜单项目。
子系统中的非菜单项（非菜单项表示该项目不需要在前端展示出来，比如有些在页面中的弹出窗口、按钮等项目）
通过单点登录到子系统以后，通过一个服务获取登录用户拥有的全部菜单，在权限基类页实现，所有需要进行权限判断的页面均集成此基类页。
代码实现如下图：AuthBasePage.cs基类页，可参考编写基类页
public class AuthBasePage : BasePage
{
/// <summary>
/// 所有的权限菜单：包含菜单项、非菜单项（如程序中的弹出页、按钮等）
/// </summary>
protected string menuHtml = string.Empty;
/// <summary>
/// 获取所有菜单的方法 用缓存
/// 通过userInfo.OpenId来更新缓存 每次进入会重新获取一次菜单，
/// </summary>
/// <param name="userInfo"></param>
/// <returns></returns>
private string GetmenuHtml(BaseUserInfo userInfo, bool refreshFlag = false)
{
string cacheKey = "menuHtml_" + userInfo.OpenId;
if (refreshFlag)
{
HttpContext.Current.Cache.Remove(cacheKey);
}
if (HttpContext.Current.Cache[cacheKey] == null)
{
lock (this)
{
if (HttpContext.Current.Cache[cacheKey] == null)
{
PermissionServiceSoapClient service = new PermissionServiceSoapClient();
string systemCode = ZTOTransferFees.Foundation.ConfigHelper.GetConfigString("SystemCode");
menuHtml = service.GetPermissionListByUser(systemCode, userInfo.Id);
menuHtml = menuHtml.Replace("Id", "id").Replace("FullName", "name").Replace("NavigateUrl", "tabUrl").Replace("Parentid", "parentId").Replace(
"ImagUrl", "icon").Replace("\"Expand\":1", "open:true");
HttpContext.Current.Cache.Add(cacheKey, menuHtml, null, DateTime.Now.AddMinutes(120), Cache.NoSlidingExpiration, CacheItemPriority.NotRemovable, null);
}
}
}
return HttpContext.Current.Cache[cacheKey] as string;
}
protected override void OnInit(EventArgs e)
{
//判断是否得到身份认证 未认证或超时时弹出登录窗口而非跳转到登录页
if (null == HttpContext.Current.User.Identity || !HttpContext.Current.User.Identity.IsAuthenticated)
{
Response.Write("<script type=\"text/javascript\">");
Response.Write("var topWin = (function (p, c) {while (p != c) {c = p;p = p.parent}return c;})(window.parent, window);");
Response.Write("try{ topWin.openLoginWindow();}catch(e){window.location='/Login.aspx'}");
Response.Write("</script>");
Response.End();
}
HttpCookie authCookie = Context.Request.Cookies[FormsAuthentication.FormsCookieName];
FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
userData = authTicket.UserData;
JavaScriptSerializer javaScriptSerializer = new JavaScriptSerializer();
userInfo = javaScriptSerializer.Deserialize<BaseUserInfo>(userData);
userInfo.ServiceUserName = BaseSystemInfo.ServiceUserName;
userInfo.ServicePassword = BaseSystemInfo.ServicePassword;
//获得全部菜单项、非菜单项的字符串（json）字符串
menuHtml = GetmenuHtml(userInfo);
//正在访问的页面，通过判断该页面是否在menuHtml中来进行权限判断，按钮等也一样
string curUrl = HttpContext.Current.Request.FilePath;
if (!menuHtml.Contains(curUrl))
{
//权限管理员的联系方式
string authManagerInfo = ZTOTransferFees.Foundation.ConfigHelper.GetConfigString("authManagerInfo");
HttpContext.Current.Items["ErrorMessage"] = "对不起，您没有权限访问页面:" + curUrl + "<br/>如有疑问，请与权限分配人联系<br/>" + authManagerInfo;
HttpContext.Current.Server.Transfer("~/Prompt/ShowNoRigh.aspx");
}
base.OnInit(e);
}
在上面我们可以看到，通过服务已经获取了该用户所拥有的所有菜单及非菜单项目 menuHtml，menuHtml代码如下，是一个Json数组， 菜单项太多，折叠起来了。

现在我们需要在用户登录以后在前端将其展示出来，这里我使用了ztree树形菜单展示控件，关键代码如下图，
var zNodes = <%=menuHtml%>;//看上面获取的数据
function initTreeMenu(b) {
if (b) {
var a = b.treeNodes;
if (a) {
$.fn.zTree.init($("#treeDemo"), setting, a)
}
}
};
由于menuHtml中包含了非菜单项目，导致非菜单项也在ztree中展示出来，如下图：
这样就不好了，如何处理这种情况呢？我想使用通用权限管理系统的都会遇到这个情况，大家都会有不同的处理方式，
如果您使用的也是ztree菜单展示控件，可参考一下我的处理方式，Js代码如下
function filter(childNodes) {
var newNodes=new Array();
for (var i = 0, l = childNodes.length; i < l; i++) {
if (childNodes[i].IsMenu) {
newNodes.push(childNodes[i]);
}
};
return newNodes;
};
var zNodes = <%=menuHtml%>;
zNodes=filter(zNodes);
function initTreeMenu(b) {
if (b) {
var a = b.treeNodes;
if (a) {
$.fn.zTree.init($("#treeDemo"), setting, a)
}
}
};
另外，如果您的菜单项是通过异步方式获取的，ztree中也有一个可以过滤菜单项的方法：
var setting = {
async: {
enable: true,
dataType: 'JSON',
dataName: 'treeNodes',
url: "/Ajax/GetMenu.aspx",
//传回的数据格式不是ztree所需要的格式的时候，可以对数据进行转化。正常情况下不需要实现dataFilter
dataFilter: filter
},
}
function filter(treeId, parentNode, childNodes) {
var newNodes=new Array();
for (var i = 0, l = childNodes.length; i < l; i++) {
if (childNodes[i].IsMenu) {
newNodes.push(childNodes[i]);
}
};
return newNodes;
};
可以看到，使用了一个过滤方法filter，将非菜单项排除掉即可，这样非菜单项就不会展示出来了，效果如下图：
使用感受：第一次在子系统开发完成后配置吉日嘎拉通用权限管理菜单项，感觉确实非常强悍，我所使用及想象的权限都已被这个组件包含了，以前从来没有看到对权限有如此深入研究的管理系统，没有对权限走火入魔十余年的研究是做不出这样的系统的，同样感受到程序员要有自己研究的领域，把一件事做好确实不容易，要经得起各种考验，适应各种使用环境，不下功夫，不经磨练是不行的。
目前只是使用这个权限系统进行菜单项的配置，吉日嘎拉权限系统底层是如何实现？如何对几十个子系统进行权限分配而不混乱？如何按角色配置权限？按组织机构配置权限？按个人进行权限配置？多种多样复杂的权限配置如何实现？今后我将在使用过程中不断与大家分享 ～～ ，敬请关注 ～～ ，
好的思想、好的成果能够节省很多资源，欢迎大家分享。
