Asterisk2B用户管理逻辑设计
前时间一直在搞Asterisk,所以打算用Asp.net结合Flex做个Asterisk的业务系统,已经在Google Code申请了http://code.google.com/p/asterisk2b/ 由于用空闲时间来做,所以进度比较难以保证。在这里会慢慢的介绍在写Asterisk2B时对于业务的设计,第一步先由用户管理逻辑开始。
用户数据是系统的基础在Asterisk2B中也不例外,首先看下需要有那些功能:用户注册,查询,信息修改等等。
根据需求定制实体对象

}
User:是用户基础信息表,通过一些Attribute把一些简单的数据验证和默认值处理了,这样能省下一些逻辑代码.
Account:是用户的费用表
SelectUserBaseInfo:是基础信息描述,毕竟在查询中很多用户信息是不需要的。
适当的使用枚举类型来代替数字或字符来描述不同情况的字段,这样在编写程序上会省一些事情,毕竟枚举是有约束的。
制定业务逻辑
![](https://www.cnblogs.com/Images/OutliningIndicators/ContractedBlock.gif)
![](https://www.cnblogs.com/Images/OutliningIndicators/ExpandedBlockStart.gif)
public class UserService
{
static object mLockRegister = new object();
//用户注册
public void Register(Entities.User user)
{
lock (mLockRegister)
{
DBContext.TransactionExecute(o =>
{
DBContext.Add(user);
Account account = new Account();
account.UserID = user.ID;
DBContext.Add(account);
});
}
}
//更改用户等级
public void SetLevel(string userid, MemberLevel level)
{
(User.iD == userid).Edit<User>(o => { o.MemberLevel = level; });
}
//设置用户有效性
public void SetEnabled(string userid, bool enabled)
{
(User.iD == userid).Edit<User>(o => { o.Enabled = enabled; });
}
//删除用户
public void Delete(string id)
{
(User.iD == id).Delete<User>();
}
//查询用户
public IList<SelectUserBaseInfo> List(string name, Smark.Core.IDataPage dp)
{
Expression exp = new Expression();
exp &= (User.parent.IsNull() | User.parent == "");
if(!string.IsNullOrEmpty(name))
exp &= User.userName.Like(name);
dp.RecordCount = exp.Count<SelectUserBaseInfo>();
return exp.List<SelectUserBaseInfo>(new Region(dp.PageIndex, dp.PageSize), null);
}
//修改用户类型
public void SetUserType(string userid, UserType type)
{
(User.iD == userid).Edit<User>(o => { o.Type = type; });
}
//修改用户密码
public void ChangePWD(string userid, string newpwd)
{
(User.iD == userid).Edit<User>(o => { o.PWD = newpwd; });
}
//修改邮件地址
public void ChangeEmail(string userid, string email)
{
(User.iD == userid).Edit<User>(o => { o.EMail = email; });
}
//获取用户信息
public User Load(string userid)
{
return DBContext.Load<User>(userid);
}
//根据用户名获取用户信息
public User LoadByName(string name)
{
return (User.userName == name).ListFirst<User>();
}
//用户登陆
public User Login(string name, string pwd)
{
User item = (User.userName == name).ListFirst<User>();
if (item == null || item.PWD != pwd)
A2BExcetion.USER_用户名或密码不正确();
return item;
}
//获取帐号信息
public Account LoadAccount(string userid)
{
return DBContext.Load<Account>(userid);
}
}
虽然业务逻辑制定了,但实际情况我们还要把业务逻辑发布到网上给Flex调用。对于现在的业务逻辑都是集中的,这样对于不同情况调用逻辑还是比较难控制。
再根据不同情况划分服务.
所有用户都能访问的
