Blackpearl 的 Impersonate

Blackpearl的Connection方法 Impersonate(string name)。这个就是传说中的后门方法，它可以帮你模拟任何一个帐号（域用户或者数据库用户），来做他可以做得事情。当然，你必须在WorkSpace中设置操作这个命令的权限。

以下代码将给用户设置Impersonate权限，包装成一个Job来定时运行就可以了：

               WorkflowManagementServer managementServer = new WorkflowManagementServer();   
                managementServer.CreateConnection();    
                managementServer.Connection.Open(GetConnectionString(dataMap));    
                AdminPermissions adminPerms = managementServer.GetAdminPermissions();    
                AdminPermissions newAdminPerms = new AdminPermissions();    
                StaffCollection staffs = Staff.GetAllStaff();    
                foreach (AdminPermission item in adminPerms)    
                {    
                    var staffName = item.UserName.Replace("K2SQL:","").Trim();    
                    Staff staff = staffs.Find(t => t.EnglishName == staffName );    
                    if (staff != null)    
                    {    
                        newAdminPerms.Add(item);    
                        staffs.Remove(staff);    
                    }    
                    else    
                    {    
                        if (item.UserName.ToUpper().Contains("K2:TENCENT"))    
                        {    
                            newAdminPerms.Add(item);    
                        }    
                    }    
                }    
                foreach (var item in staffs)    
                {    
                    AdminPermission adminPermission = new AdminPermission();    
                    adminPermission.CanImpersonate = true;    
                    adminPermission.UserName = string.Format("K2SQL:{0}", item.EnglishName);    
                    newAdminPerms.Add(adminPermission);    
                }    
                managementServer.UpdateAdminUsers(newAdminPerms);

Impersonate方法的调用可以参照K2 blackpearl Client Impersonation - Suggested Design Pattern包装后使用，下面是我的包装代码：

    ///{

    {    
        private IK2Connection _conn = null;

            if (!userName.ToUpper().Contains("K2SQL"))    
            {    
                userName = string.Format("K2SQL:{0}", userName);    
            }    
            conn.Connection.ImpersonateUser(userName);    
            return new Impersonation(conn);    
        }
        #endregion Impersonate Methods
