. NET permission management and. net permission management
Preface: There are many application permission management functions in various aspects for powerful back-end website management. Taking the internal management system of the company as an example, administrators can grant different permissions to different departments of different employees, or implement "Pyramid" Management Based on the parent-subordinate affiliation (note: the granted permission management mode cannot be dynamically edited, that is, the level-2 and above permissions cannot be divided ). I suggest you correct the content of this article.
Body:
Check whether a user has the permission to use checkbox status to differentiate storage.
(1) Storage
Here, the permission function (Category) Name and permission module (specific) name are manually entered into the database and cannot be added, deleted, modified, and queried. In this example, a permission module is used as the most basic element, and whether the permission is expressed as 1 or 0. Then, all the permissions of the current user are linked to a binary string and stored in the database. Example code 1.1
(2) readingExample code 1.2
(3) the front-end code is as follows:
// Add a comma and a vertical bar using js, and pass the value <script language = "javascript" type = "text/javascript"> function getcheck () {var inputs = document through hidden. getElementById ("cbpanel"); var chks = inputs. getElementsByTagName ("input"); var str = ""; for (var I = 0; I <chks. length; I ++) {if (chks [I]. type = 'checkbox') {str + = chks [I]. value + "," + chks [I]. checked + "|" ;}} document. getElementById ("Hidden1 "). value = str ;}< script> <body> <div id = "cbpanel"> <asp: Literal ID = "LiteralRole" runat = "server"> </asp: literal> <input id = "Hidden1" runat = "server" type = "hidden"/> </div> </body>
Sample Code 1.2 // <summary> // bind all module categories /// </summary> private void BindAllModule () {StringBuilder sb = new StringBuilder (); sb. append ("<table class = \" AddRole \ "width = \" 100% \ "border = \" 0 \ "cellpadding = \" 0 \ "cellspacing = \" 0 \"> "); bll_User_Module created L = new Bll_User_Module (); IList <User_Model.Model_User_Module> list = created L. getAllList (); // obtain the string moduleidstr = ""; for (int I = 0; I <list. count; I ++) {Sb. append ("<tr> <th style = \" width: 100px; height: 36px; \ ">"); sb. append (list [I]. moduleName); sb. append ("</th>"); sb. append ("<td>"); sb. append ("{" + list [I].
