权限分配
1.在项目中新建文件夹Helpers
2.在HR.Helpers文件夹下添加EnumMoudle.Cs
namespace HR.Helpers { public enum EnumMoudle { /// <summary> /// 模块 /// </summary> [EnumTitle("用户管理")] SysUserManage_Role = 102,
[EnumTitle("机构管理")] Department = 201, [EnumTitle("人事资料")] Employees = 301, [EnumTitle("系统管理")] BaseInfo = 404, } }
3.在HR.Helpers文件夹下添加ControllerBase.Cs
1 namespace HR.Helpers 2 { 3 public class ControllerBase : Controller 4 { 5 /// <summary> 6 /// 操作人，传IP....到后端记录 7 /// </summary> 8 public virtual Operater Operater 9 { 10 get 11 { 12 return null; 13 } 14 } 15 16 /// <summary> 17 /// 分页大小 18 /// </summary> 19 public virtual int PageSize 20 { 21 get 22 { 23 return 15; 24 } 25 } 26 27 protected ContentResult JsonP(string callback, object data) 28 { 29 var json = Newtonsoft.Json.JsonConvert.SerializeObject(data); 30 return this.Content(string.Format("{0}({1})", callback, json)); 31 } 32 33 /// <summary> 34 /// 当弹出DIV弹窗时，需要刷新浏览器整个页面 35 /// </summary> 36 /// <returns></returns> 37 public ContentResult RefreshParent(string alert = null) 38 { 39 var script = string.Format("<script>{0}; parent.location.reload(1)</script>", string.IsNullOrEmpty(alert) ?

4.在项目文件夹中新建ControllerBase.cs
namespace HR { public abstract class ControllerBase:HR.Helpers.ControllerBase { protected override void OnActionExecuted(ActionExecutedContext filterContext) { base.OnActionExecuted(filterContext); } protected override void OnActionExecuting(ActionExecutingContext filterContext) { base.OnActionExecuting(filterContext); } } }
5.在项目中新建RoleControllerBase.cs
namespace HR { public class RoleControllerBase : ControllerBase { SystemUserRepository sysuserrepository = new SystemUserRepository(); /// <summary> /// 用户权限 /// </summary> public virtual List<EnumMoudle> PermissionList { get { var permissionList = new List<EnumMoudle>(); return permissionList; } } public string BusinessPermissionString { get; set; } [NotMapped] public List<EnumMoudle> BusinessPermissionList { get { if (string.IsNullOrEmpty(BusinessPermissionString)) return new List<EnumMoudle>(); else return BusinessPermissionString.Split(",".ToCharArray()).Select(p => int.Parse(p)).Cast<EnumMoudle>().ToList(); } set { BusinessPermissionString = string.Join(",", value.Select(p => (int)p)); } } /// <summary> /// Action方法执行前没有权限提示信息 /// </summary> /// <param name="filterContext"></param> protected override void OnActionExecuting(ActionExecutingContext filterContext) { var noAuthorizeAttributes = filterContext.ActionDescriptor.GetCustomAttributes(typeof(AuthorizeIgnoreAttribute), false); if (noAuthorizeAttributes.Length > 0) return; base.OnActionExecuting(filterContext); bool hasPermission = true; var permissionAttributes = filterContext.ActionDescriptor.ControllerDescriptor.GetCustomAttributes(typeof(PermissionAttribute), false).Cast<PermissionAttribute>(); permissionAttributes = filterContext.ActionDescriptor.GetCustomAttributes(typeof(PermissionAttribute), false).Cast<PermissionAttribute>().Union(permissionAttributes); var attributes = permissionAttributes as IList<PermissionAttribute> ?? permissionAttributes.ToList(); if (permissionAttributes != null && attributes.Count() > 0) { string cookie = CookieHelper.GetValue("SystemUserID"); if (string.IsNullOrEmpty(cookie)) { filterContext.Result = Content("您没有登录！"); } else { int mid = int.Parse(CookieHelper.GetValue("SystemUserID")); var model = sysuserrepository.GetModel(mid); BusinessPermissionString = model.BusinessPermissionString; hasPermission = true; foreach (var attr in attributes) { foreach (var permission in attr.Permissions) { if (!BusinessPermissionList.Contains(permission)) { hasPermission = false; break; } } } if (!hasPermission) { if (Request.UrlReferrer != null) filterContext.Result = this.Stop("您没有权限！", "/default/ng"); else filterContext.Result = Content("您没有权限！"); } } } } } }
6.在每个Controller继承RoleControllerBase类
public class EmployeesController : RoleControllerBase
7.在HR.Helpers文件夹下添加PermissionAttribute.Cs ，并继承 FilterAttribute, IActionFilter
namespace HR.Helpers { public class PermissionAttribute : FilterAttribute, IActionFilter { public List<EnumMoudle> Permissions { get; set; } public PermissionAttribute(params EnumMoudle[] parameters) { Permissions = parameters.ToList(); } public void OnActionExecuted(ActionExecutedContext filterContext) { //throw new NotImplementedException(); } public void OnActionExecuting(ActionExecutingContext filterContext) { //throw new NotImplementedException(); } } }
8.然后在Controller或者Action方法加上验证
[Permission(EnumMoudle.Employees),Authorize, ValidateInput(false)] [Permission(EnumMoudle.SysUserManage_Role)]
9.在用户管理Controller中添加权限分配，修改方法
#region 添加管理员 /// <summary> /// 添加页 /// </summary> /// <param name="model">管理员实体类</param> /// <returns></returns> [Authorize] public ActionResult Add() { var moudleList = EnumHelper.GetItemValueList<EnumMoudle>(); this.ViewBag.MoudleList = new SelectList(mouldeList, "Key", "Value"); return View(); } /// <summary> /// 添加事件 /// </summary> /// <param name="model">实体类</param> /// <param name="fc"></param> /// <returns></returns> [Authorize, HttpPost, ValidateInput(false)] public ActionResult Add(SystemUser model, FormCollection fc) { model.BusinessPermissionString = fc["MoudelList"]; model.State = 1; model.CreateTime = DateTime.Now; systemuserrepository.SaveOrEditModel(model); return RedirectToAction("UserList"); } #endregion //修改权限 [Authorize, AcceptVerbs(HttpVerbs.Post), ValidateInput(false)] public ActionResult Edit(int id, FormCollection fc) { var model = systemuserrepository.GetModel(id); if (model != null) { string password = model.PassWord; if (Request.Form["PassWord"] != "") { model.BusinessPermissionString = fc["MoudleList"]; UpdateModel(model); systemuserrepository.SaveOrEditModel(model); } else { model.BusinessPermissionString = fc["MoudleList"]; UpdateModel(model); model.PassWord = password; systemuserrepository.SaveOrEditModel(model); } return RedirectToAction("userlist"); } else return View("404"); } #endregion
[Authorize] public ActionResult Edit(int id) { var model = systemuserrepository.GetModel(id); if (model != null) { var moudleList = EnumHelper.GetItemValueList<EnumBusinessPermission>(); this.ViewBag.MoudleList = new SelectList(moudleList, "Key", "Value", string.Join(",", model.BusinessPermissionString.ToString())); return View(model); } else return View("404"); }
