最近这几天很忙,一边忙着准备一堆课程设计(8门专业课.....伤不起...时间都是靠挤),一边还要党校培训....呃......顺便做了一下购物车,订单和支付宝简单的流程.

上次,曾经说到一个URL管理的问题,比如我们很多页面为了性能考虑生成静态页面,我们经常

性刚开始的时候用动态页面+ajax的方式加载,页面静态化的时候,如果是新闻内容页,我们可以

把静态页面的URL地址保存在数据库中,但是,单个页面,比如,首页,会员空间的各个页面,就不

适合放在数据库中,这时候更适合写一个通用模块类似MVC中的"控制器"来控制页面的静态化

和URL重写,这就省去了一个一个很繁琐的过程.

打个比方,我们可以写一个通用模块调用:

这种方式类似asp.net 中MVC的控制器,

函数大致的代码思路:

1:      ///

2:      /// 获得路径(暂时只做静态页面管理)(/*在这里可以扩展出URL重写*/)

3:      ///

4:      /// 页面的URL(不包括扩展名)

5:      /// 页面参数

6:      ///

7:      public static string GetURL(string PageUrl,string QueryString)

8:      {

9:          //页面路径

10:          string PagePath = "";

11:

12:          //如果当前的参数不为空,则加上?

13:          if (QueryString != "")

14:              QueryString = "?" + QueryString;

15:          //如果是静态页面(从配置文件中读取静态页面状态(是否))

16:          if (ReadURLConfig(PageUrl) == true)

17:          {

18:              PagePath=PageUrl + ".htm" + QueryString;

19:          }

20:          //如果是动态页面

21:          else

22:              PagePath = PageUrl + ".aspx" + QueryString;

23:          //把相对路径转化为绝对路径

24:          return   System.Web.VirtualPathUtility.ToAbsolute(PagePath); ;

25:      }

26:      ///

27:      /// 从配置文件中读取是否生成静态页面

28:      ///

29:      /// 页面的名称

30:      ///

31:      public static bool ReadURLConfig(string PageName)

32:      {

33:          //读取配置文件

34:          string path = HttpContext.Current.Server.MapPath(@"~/Admin/ConfigManage/URLConfig.xml");

35:          //XmlHelper.Read(path, "/Node/Element[@Attribute='Name']", "Attribute")

36:          //是否生成HTML

37:          string IsHtml="false";

38:          IsHtml=XMlHelper.Read(path, "/PageSettings/Page[@PageName='"+PageName+"']", "IsHtml");

39:          if (IsHtml.ToLower() == "true")

40:          {

41:              return true;

42:          }

43:          else return false;

44:

45:      }

配置文件属性:(URL重写部分,还没有实现)

我们可以在后台设置那些页面要生成HTML和URL重写规则的定制.......

不过貌似还有好多没实现,正在思考中............

进入主题:

这次,主要是购物车的实现,购物车的实现,我是在数据库建立了一个购物车的临时表,本来打算用Cookies做,不过,先用数据库做,比较稳妥,Cookies涉及安全性处理需要做很多处理.呃....这个以后可能会深入实现.

首先是,当用户点击

呃.....就ajax加入购物车,然后弹出层,显示

主要是ajax,先加入购物车(加入购物车之前,要检查购物车是否存在此商品,如果存在,本来应该

把购物车中商品的数量+1,我这里是直接提示用户已加入购物车,这是个小BUG),然后回调计

算购物车中的宝贝数量和总金额.

代码不太重要,这里就不粘贴了.

主要是思路要清晰一些.接下来就是购物车结算.

这个用了一个框架(改改颜色就上了,不过感觉加载了好多js,呃,....不过总比asp.net服务端控

件实现要好得多).

这个也就是增删改查设计,不过值得一提的就是,我们尽量把大量的前台js代码单独放在一个文

件中,这样客户端的缓存起来第二次访问起来就只需要更少的请求.

前台代码非常简洁:

1:  <%@ Page Language="C#" MasterPageFile="~/Member.master" AutoEventWireup="true" CodeFile="ShopingCart.aspx.cs"

2:      Inherits="Member_ShopingCart" Title="购物车" %>

接下来就是订单结算,

呃...订单很丑...没做处理.....

其实,这里面大部分信息都是以前做会员信息管理的数据加载,只需要调用会员管理的js,根本业务逻辑都不用写....

相对来说难写一点的就是提交订单的处理,

首先我们要提交订单,我的数据库,设计了订单表和订单商品表,订单号是根据日期生成的,订单号的生成就是类似流水号生成,

这个很重要,因为大多数情况下,订单是日期生成,而且要保证唯一性,以前曾经总看到(数据库的id不设计成自增,然后varchar类型,程序生成id号),

这种设计方式就是严重没考虑并发处理的情况,如果同时n个人订单号根本就不能保证唯一性...

到网上搜索流水号生成,就能看到如何解决这个问题,其实就是建一张表,写存储过程的方式计算id,要保证id的唯一性.

我的这个是从博客园一个高手的日志上切下来的..

获取订单号的存储过程

1:  USE [czcraft]

2:  GO

3:  /****** 对象:  StoredProcedure [dbo].[dpPMT_SGetMaintainSeq]    脚本日期: 05/19/2012 00:18:39 ******/

4:  SET ANSI_NULLS ON

5:  GO

6:  SET QUOTED_IDENTIFIER ON

7:  GO

8:

9:  CREATE  PROC [dbo].[dpPMT_SGetMaintainSeq]

10:  (

11:  @MaintainCate VARCHAR(2)

12:  )

13:   AS

14:  --***********************累加编号*************************************************

15:  declare @MaintainNo VARCHAR(12) IF NOT EXISTS(SELECT * FROM NumSeq WHERE Cate=@MaintainCate AND DATEDIFF(DAY,CrTime,GETDATE())=0) BEGIN

16:          INSERT INTO NumSeq(Cate,DateNo,Seq,CrTime) values(@MaintainCate,RIGHT(CONVERT(VARCHAR(4),YEAR(GETDATE())),2)+ REPLICATE('0',2-LEN(MONTH(GETDATE())))+CONVERT(VARCHAR(2),MONTH(GETDATE())),0,getdate()) END

17:  ELSE

18:      BEGIN

19:          UPDATE NumSeq SET Seq=Seq+1 WHERE Cate=@MaintainCate AND DateNo=RIGHT(CONVERT(VARCHAR(4),YEAR(GETDATE())),2)+ REPLICATE('0',2-LEN(MONTH(GETDATE())))+CONVERT(VARCHAR(2),MONTH(GETDATE())) END

20:  --************************组合编号***************************************************************

21:  SELECT @MaintainNo=Cate+DateNo+REPLICATE('0',6-LEN(Seq))+CONVERT(VARCHAR(6),Seq) FROM NumSeq WHERE Cate=@MaintainCate AND DateNo=RIGHT(CONVERT(VARCHAR(4),YEAR(GETDATE())),2)+ REPLICATE('0',2-LEN(MONTH(GETDATE())))+CONVERT(VARCHAR(2),MONTH(GETDATE())) SELECT @MaintainNo

调用函数

这样,我们每次插入数据的时候,只要调用这个存储过程就能保证每次生成的订单号都不一样,

接下来就是订单处理了:

我们需要处理哪些呢?

首先是提交用户的收货信息,再次检验库存状态,然后插入订单信息表和订单产品表,并且将商品表的产品数量更新,并且给用户发送订单邮件(我copy的卓越网邮件的HTML布局,哈哈),

这里粘贴主要模块代码:

提交订单:

在这里,为了更节省性能,我用StringBuilder拼接字符串,也没有用参数化查询的方式.(注意这里采用事务处理)

然后就是支付平台的实现,其实支付平台说简单点是非常容易的,只需要按照支付的接口提供http请求参数,数字签名,等信息,交易成功然后按照请求读取参数检验数字签名是否正确.

这部分内容,我是准备集成多种支付平台设计,今天只展示支付宝部分.

在设计这部分,我们需要去查看支付宝接口模拟,一般申请支付宝都会提供一个接口测试程序,等等,

我们在做之前,为了考虑多种支付平台的配置,首先定义一些配置信息,

我是把支付宝接口配置成一个网站,然后,通过网关调用,进行模拟
