权限管理系统-将权限授权给角色

过了个年回来,回顾一下,我们上次讲了角色管理,我们这一次来讲将权限授权给角色,这一节也是大家比较关心的。因为我们已经跑通了整个系统,知道权限的流转,我们先来看一张图

这张图主要分要3块,角色组----系统模块----操作码授权

选择角色组(表示要授权的角色,选择需要授权的模块,最后授权操作码。当存在一个操作码时候,我们应该改变SysRight表中的rightflag字段,表示他有权限。不知道大家是否还记得,这个图也是我们要做的。由于图中用的是JQGrid看起来跟Easyui有点差别,但是方式却是一样的)

回到头看到SysRightOperate表的IsValid,我们将授权角色和模块和操作码这3张表关联起来,其中IsValid字段是来标识是否有操作的权限,当第一次授权,那么是向SysRightOperate添加一条记录,如果下次更新先判断是否已经授权如果没有,那么删除或者更新IsValid,我这里是更新,你也可以删除掉,一样的道理。

之前我们已经新建过SysRight这个表的DAL层和BLL层了,根据想法,我们只要建立多两个方法

  • 更新SysRightOperate(即上面所说)

  • 和按选择的角色及模块加载模块的权限项(确定操作码是否被授权,即图中的复选框)

现在向ISysRightRepository添加2个方法

//更新
int UpdateRight(SysRightOperate model);
//按选择的角色及模块加载模块的权限项
List<P_Sys_GetRightByRoleAndModule_Result> GetRightByRoleAndModule(string roleId, string moduleId);

P_Sys_GetRightByRoleAndModule_Result这个是存储过程,由于这2个方法比较复杂,这里用存储过程来做

Create proc [dbo].[P_Sys_GetRightByRoleAndModule]
@roleId varchar(50),@moduleId varchar(50)
as
--按选择的角色及模块加载模块的权限项
begin
select a.Id,a.Name,a.KeyCode,a.ModuleId,ISNULL(b.IsValid,0) as isvalid,a.Sort,@roleId+@moduleId as RightId
    from SysModuleOperate a
    left outer join(
        select c.Id,a.IsValid from SysRightOperate a,SysRight b, SysModuleOperate c
        where RightId in
        (select Id From SysRight where RoleId =@roleId and ModuleId =@moduleId)
         and a.RightId=b.Id
         and b.ModuleId=c.ModuleId
         and a.KeyCode =c.KeyCode) b
     on a.Id = b.Id
     where a.ModuleId =@moduleId
end

    

所以必须要把这个存储过程添加到EF,并生成复杂类型的实体P_Sys_GetRightByRoleAndModule_Result

然后创建P_Sys_UpdateSysRightRightFlag

Create proc [dbo].[P_Sys_UpdateSysRightRightFlag]
@moduleId varchar(200),@roleId varchar(200)
as
begin
--计算上级模块的rightflag标识
declare @count int
--第一层:由操作权限项计算模块权限
select @count=COUNT(*) from SysRightOperate where RightId=@roleId+@moduleId and IsValid=1

if(@count>0)
begin
    update SysRight set Rightflag=1 where ModuleId=@moduleId and RoleId=@roleId
end
else
begin
    update SysRight set Rightflag=0 where ModuleId=@moduleId and RoleId=@roleId
end
--计算下一层
declare @parentId varchar(50)
set @parentId=@moduleId

while(@parentId<>'0')
begin
    select @parentid=ParentId from SysModule where Id=@parentId
    if (@parentId is null)
    begin
        return
    end
    
    select @count=COUNT(*) from SysRight where ModuleId in
        (select Id from SysModule where ParentId=@parentId)
        and RoleId =@roleId
        and Rightflag=1
    
    if(@count>0)
    begin
        update SysRight set Rightflag=1 where ModuleId=@parentId and RoleId=@roleId
    end
    else
    begin
        update SysRight set Rightflag=0 where ModuleId=@parentId and RoleId=@roleId
    end
end
end

这个是计算上级模块的rightflag标识也就是开头所说的RightFlag字段,这个字段将决定导航条的显示,所以每一次授权操作都要执行

下面添加SysRightRepository逻辑代码

  public int UpdateRight(SysRightOperateModel model)
        {
            //转换
            SysRightOperate rightOperate = new SysRightOperate();
            rightOperate.Id = model.Id;
            rightOperate.RightId = model.RightId;
            rightOperate.KeyCode = model.KeyCode;
            rightOperate.IsValid = model.IsValid;
            //判断rightOperate是否存在,如果存在就更新rightOperate,否则就添加一条
            using (DBContainer db = new DBContainer())
            {
                SysRightOperate right = db.SysRightOperate.Where(a => a.Id == rightOperate.Id).FirstOrDefault();
                if (right != null)
                {
                    right.IsValid = rightOperate.IsValid;
                }
                else
                {
                    db.SysRightOperate.AddObject(rightOperate);
                }
                if (db.SaveChanges() > 0)
                {
                    //更新角色--模块的有效标志RightFlag
                    var sysRight = (from r in db.SysRight
                                    where r.Id == rightOperate.RightId
                                    select r).First();
                    db.P_Sys_UpdateSysRightRightFlag(sysRight.ModuleId, sysRight.RoleId);
                    return 1;
                }
            }
            return 0;
        }
        //按选择的角色及模块加载模块的权限项
        public List<P_Sys_GetRightByRoleAndModule_Result> GetRightByRoleAndModule(string roleId, string moduleId)
        {
            List<P_Sys_GetRightByRoleAndModule_Result> result = null;
            using (DBContainer db = new DBContainer())
            {
                result = db.P_Sys_GetRightByRoleAndModule(roleId,moduleId).ToList();
            }
            return result;
        }

按照习惯,我们要向IBLL 和BLL 添加代码,大家自行添加访问DAL层的代码即可

比较繁琐的还是Controller层和页面UI的代码,这些先贴出

这次发布还是做得比较认真的。大家可以详细细读代码和存储过程。不清楚的欢迎留言,必定回答

接下来是讲角色和用户的互相授权,有兴趣的朋友可以先做做看。

最后更新2个js方法来替换DataGrid中的width和height计算

function SetGridWidthSub(w)
{
    return $(window).width() - w;
}
function SetGridHeightSub(h) {
    return $(window).height() - h
}
