從這篇文章，希望您能夠了解吉日嘎拉通用權限管理系統菜單項配置、緩存及在前台的展示技巧。
項目中使用了吉日嘎拉的通用權限管理系統，幾十個子系統均由該權限管理系統管理。
在系統中配置好相關菜單及非菜單項，配置截圖：
菜單權限設置截圖
通過下拉菜單進入其中的一個子系統
子系統中的菜單項（菜單項表示該項會在前端需要展示出來，用於用戶點擊的項目），其中的公開表示所有人均可看到該菜單項目。
子系統中的非菜單項（非菜單項表示該項目不需要在前端展示出來，比如有些在頁面中的彈出窗口、按鈕等項目）
通過單點登錄到子系統以後，通過一個服務獲取登錄用戶擁有的全部菜單，在權限基類頁實現，所有需要進行權限判斷的頁面均集成此基類頁。
代碼實現如下圖：AuthBasePage.cs基類頁，可參考編寫基類頁
public class AuthBasePage : BasePage
{
/// <summary>
/// 所有的權限菜單：包含菜單項、非菜單項（如程序中的彈出頁、按鈕等）
/// </summary>
protected string menuHtml = string.Empty;
/// <summary>
/// 獲取所有菜單的方法 用緩存
/// 通過userInfo.OpenId來更新緩存 每次進入會重新獲取一次菜單，
/// </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)
{
//判斷是否得到身份認證 未認證或超時時彈出登錄窗口而非跳轉到登錄頁
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;
//獲得全部菜單項、非菜單項的字符串（json）字符串
menuHtml = GetmenuHtml(userInfo);
//正在訪問的頁面，通過判斷該頁面是否在menuHtml中來進行權限判斷，按鈕等也一樣
string curUrl = HttpContext.Current.Request.FilePath;
if (!menuHtml.Contains(curUrl))
{
//權限管理員的聯系方式
string authManagerInfo = ZTOTransferFees.Foundation.ConfigHelper.GetConfigString("authManagerInfo");
HttpContext.Current.Items["ErrorMessage"] = "對不起，您沒有權限訪問頁面:" + curUrl + "<br/>如有疑問，請與權限分配人聯系<br/>" + authManagerInfo;
HttpContext.Current.Server.Transfer("~/Prompt/ShowNoRigh.aspx");
}
base.OnInit(e);
}
在上面我們可以看到，通過服務已經獲取了該用戶所擁有的所有菜單及非菜單項目 menuHtml，menuHtml代碼如下，是一個Json數組， 菜單項太多，折疊起來了。

現在我們需要在用戶登錄以後在前端將其展示出來，這裡我使用了ztree樹形菜單展示控件，關鍵代碼如下圖，
var zNodes = <%=menuHtml%>;//看上面獲取的數據
function initTreeMenu(b) {
if (b) {
var a = b.treeNodes;
if (a) {
$.fn.zTree.init($("#treeDemo"), setting, a)
}
}
};
由於menuHtml中包含了非菜單項目，導致非菜單項也在ztree中展示出來，如下圖：
這樣就不好了，如何處理這種情況呢？我想使用通用權限管理系統的都會遇到這個情況，大家都會有不同的處理方式，
如果您使用的也是ztree菜單展示控件，可參考一下我的處理方式，Js代碼如下
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，如果您的菜單項是通過異步方式獲取的，ztree中也有一個可以過濾菜單項的方法：
var setting = {
async: {
enable: true,
dataType: 'JSON',
dataName: 'treeNodes',
url: "/Ajax/GetMenu.aspx",
//傳回的數據格式不是ztree所需要的格式的時候，可以對數據進行轉化。正常情況下不需要實現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，使用了一個過濾方法filter，將非菜單項排除掉即可，這樣非菜單項就不會展示出來了，效果如下圖：
使用感受：第一次在子系統開發完成後配置吉日嘎拉通用權限管理菜單項，感覺確實非常強悍，我所使用及想象的權限都已被這個組件包含了，以前從來沒有看到對權限有如此深入研究的管理系統，沒有對權限走火入魔十余年的研究是做不出這樣的系統的，同樣感受到程序員要有自己研究的領域，把一件事做好確實不容易，要經得起各種考驗，適應各種使用環境，不下功夫，不經磨練是不行的。
目前只是使用這個權限系統進行菜單項的配置，吉日嘎拉權限系統底層是如何實現？如何對幾十個子系統進行權限分配而不混亂？如何按角色配置權限？按組織機構配置權限？按個人進行權限配置？多種多樣復雜的權限配置如何實現？今後我將在使用過程中不斷與大家分享 ～～ ，敬請關注 ～～ ，
好的思想、好的成果能夠節省很多資源，歡迎大家分享。
