BrnShop开源网上商城第四讲：自定义插件
重要通知：BrnShop企业版NOSQL设计(基于Redis)已经开源！源码内置于最新版的BrnShop中，感兴趣的园友可以去下载来看看。官网地址：www.brnshop.com。
好了现在进入今天的正题：自定义插件。上一讲中我们已经阐述了BrnShop插件的工作机制，现在我们详细介绍下如何自定义插件。首先BrnShop的插件从功能上分为三类,分别是：
- 开放授权插件(OAuth)
- 支付插件
- 配送插件
对应的接口文件(注:位于BrnShop.Core项目的Plugin/Base文件夹中)依次如下:
- IOAuthPlugin
- IPayPlugin
- IShipPlugin
现在我们依次介绍下各个接口，首先登场的是IOAuthPlugin接口。先看它的定义：
/// <summary>
/// BrnShop开放授权插件接口
/// </summary>
public interface IOAuthPlugin : IPlugin
{
/// <summary>
/// 登陆控制器
/// </summary>
string LoginController { get; }
/// <summary>
/// 登陆动作方法
/// </summary>
string LoginAction { get; }
/// <summary>
/// 登陆路由数据
/// </summary>
RouteValueDictionary LoginRouteValues { get; }
}
对于一个开放授权插件来说，它只需要向主应用程序提供自己的一个登陆地址就可以，至于怎么授权验证等那都是插件自己的事情了。所以IOAuthPlugin接口内容仅仅是登陆地址的mvc3要素(控制器名，动作方法名，路由数据)就可以了，以QQ授权登陆为例：
接下来是IPayPlugin接口，代码如下：
/// <summary>
/// BrnShop支付插件接口
/// </summary>
public interface IPayPlugin : IPlugin
{
/// <summary>
/// 付款方式(0代表货到付款，1代表在线付款，2代表线下付款)
/// </summary>
int PayMode { get; }
/// <summary>
/// 是否允许账户充值(只对在线付款有效)
/// </summary>
bool AllowRecharge { get; }
/// <summary>
/// 支付返回控制器
/// </summary>
string ReturnController { get; }
/// <summary>
/// 支付返回动作方法
/// </summary>
string ReturnAction { get; }
/// <summary>
/// 支付返回路由数据
/// </summary>
RouteValueDictionary ReturnRouteValues { get; }
/// <summary>
/// 支付通知控制器
/// </summary>
string NotifyController { get; }
/// <summary>
/// 支付通知动作方法
/// </summary>
string NotifyAction { get; }
/// <summary>
/// 支付通知路由数据
/// </summary>
RouteValueDictionary NotifyRouteValues { get; }
/// <summary>
/// 获得支付手续费
/// </summary>
/// <param name="productAmount">商品合计</param>
/// <param name="buyTime">购买时间</param>
/// <param name="partUserInfo">购买用户</param>
/// <returns></returns>
decimal GetPayFee(decimal productAmount, DateTime buyTime, PartUserInfo partUserInfo);
/// <summary>
/// 如果付款方式为在线付款则返回付款请求的url，否则返回空字符串
/// </summary>
/// <param name="returnUrl">返回url</param>
/// <param name="notifyUrl">通知url</param>
/// <param name="pluginInfo">插件信息</param>
/// <param name="partUserInfo">购买用户</param>
/// <param name="orderInfo">订单信息</param>
/// <returns></returns>
string GetRequestUrl(string returnUrl, string notifyUrl, PluginInfo pluginInfo, PartUserInfo partUserInfo, OrderInfo orderInfo);
}
/// <summary>
/// BrnShop支付插件接口
/// </summary>
public interface IPayPlugin : IPlugin
{
/// <summary>
/// 付款方式(0代表货到付款，1代表在线付款，2代表线下付款)
/// </summary>
int PayMode { get; }
/// <summary>
/// 是否允许账户充值(只对在线付款有效)
/// </summary>
bool AllowRecharge { get; }
/// <summary>
/// 支付返回控制器
/// </summary>
string ReturnController { get; }
/// <summary>
/// 支付返回动作方法
/// </summary>
string ReturnAction { get; }
/// <summary>
/// 支付返回路由数据
/// </summary>
RouteValueDictionary ReturnRouteValues { get; }
/// <summary>
/// 支付通知控制器
/// </summary>
string NotifyController { get; }
/// <summary>
/// 支付通知动作方法
/// </summary>
string NotifyAction { get; }
/// <summary>
/// 支付通知路由数据
/// </summary>
RouteValueDictionary NotifyRouteValues { get; }
/// <summary>
/// 获得支付手续费
/// </summary>
/// <param name="productAmount">商品合计</param>
/// <param name="buyTime">购买时间</param>
/// <param name="partUserInfo">购买用户</param>
/// <returns></returns>
decimal GetPayFee(decimal productAmount, DateTime buyTime, PartUserInfo partUserInfo);
/// <summary>
/// 如果付款方式为在线付款则返回付款请求的url，否则返回空字符串
/// </summary>
/// <param name="returnUrl">返回url</param>
/// <param name="notifyUrl">通知url</param>
/// <param name="pluginInfo">插件信息</param>
/// <param name="partUserInfo">购买用户</param>
/// <param name="orderInfo">订单信息</param>
/// <returns></returns>
string GetRequestUrl(string returnUrl, string notifyUrl, PluginInfo pluginInfo, PartUserInfo partUserInfo, OrderInfo orderInfo);
}
成员比较多，我们分类来看就清晰了：
- PayMode：代表支付的3种类型，这个属性非常重要，因为其它成员的实现跟他密切相关。
- GetPayFee：计算订单的支付手续费。
- GetRequestUrl：只在PayMode为在线付款时有效；返回支付地址，在BrnShop.Web项目的OrderController类的PayShow方法中调用。
- ReturnController，ReturnAction，ReturnRouteValues：这3个成员为一组，并且只在PayMode为在线付款时有效；提供支付完成后的返回地址。
- NotifyController，NotifyAction，NotifyRouteValues：这3个成员为一组，并且只在PayMode为在线付款时有效；提供支付完成后的回调地址。
- AllowRecharge：系统预留成员，目前无用。
最后我们来看下IShipPlugin接口，代码如下：
/// <summary>
/// BrnShop配送插件接口
/// </summary>
public interface IShipPlugin : IPlugin
{
/// <summary>
/// 获得配送费用
/// </summary>
/// <param name="totalWeight">订单总重量</param>
/// <param name="productAmount">商品合计</param>
/// <param name="buyTime">购买时间</param>
/// <param name="shipRegionId">收货区域</param>
/// <param name="partUserInfo">购买用户</param>
/// <returns></returns>
decimal GetShipFee(int totalWeight, decimal productAmount, DateTime buyTime, int shipRegionId, PartUserInfo partUserInfo);
}
这个接口比较简单，只是提供一个计算配送费用的成员。
补充说明一下：以上3个接口都继承自IPlugin，这个接口提供后台配置地址mvc3要素，只在BrnShop.Web.Admin项目中的插件配置视图中使用，具体如下：
@if (Model.ConfigRouteValues == null)
{
@Html.Action(Model.ConfigAction, Model.ConfigController)
}
else
{
@Html.Action(Model.ConfigAction, Model.ConfigController, Model.ConfigRouteValues)
}
下面我们以支付宝插件为例来讲解下如何自定义一个插件。
首先新建一个ASP.NET MVC3应用程序并引用需要的程序集，根据上一篇讲解我们知道需要修改非.net自带程序集的复制到本地属性和项目生成属性。具体如下图：
至此我们的项目基本框架已经搭好了。现在我们需要添加一个插件说明文件(注：此文件为必须文件且文件名称必须为PluginInfo.config，还有不要忘记修改它的复制属性)。内容如下：
<?xml version="1.0" encoding="utf-8"?> <PluginInfo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <SystemName>alipay</SystemName> <FriendlyName>支付宝</FriendlyName> <ClassFullName>BrnShop.PayPlugin.Alipay.PluginService,BrnShop.PayPlugin.Alipay</ClassFullName> <Folder>BrnShop.PayPlugin.Alipay</Folder> <Description>阿里巴巴旗下支付工具</Description> <Type>1</Type> <Author>brnshop</Author> <Version>1.0</Version> <SupVersion>1.0.0</SupVersion> <DisplayOrder>3</DisplayOrder> <IsDefault>0</IsDefault> </PluginInfo>
这个文件是BrnShop.Core项目中的PluginInfo序列化文件，所以节点说明请参考下面代码：
/// <summary>
/// 插件信息类
/// </summary>
public class PluginInfo : IComparable
{
private string _systemname = "";//插件系统名称(必须具有唯一性)

return 1;
else if (this.DisplayOrder < info.DisplayOrder)

}
接下来我们定义一个类PluginService，并实现接口IPayPlugin，代码如下：

{
//支付类型，必填，不能修改

}
}
因为支付宝有一些需要配置的属性要保存，例如收款支付宝帐户等。在此我们采用对象序列化和文件的方式来保存这些信息。首先定义一个设置信息类，代码如下：
/// <summary>
/// 插件设置信息类
/// </summary>
public class PluginSetInfo
{
private string _partner;//合作者身份ID
private string _key;//交易安全检验码
private string _seller;//收款支付宝帐户
private int _allowrecharge;//是否允许账户充值
/// <summary>
/// 合作者身份ID
/// </summary>
public string Partner
{
get { return _partner; }
set { _partner = value; }
}
/// <summary>
/// 交易安全检验码
/// </summary>
public string Key
{
get { return _key; }
set { _key = value; }
}
/// <summary>
/// 收款支付宝帐户
/// </summary>
public string Seller
{
get { return _seller; }
set { _seller = value; }
}
/// <summary>
/// 是否允许账户充值
/// </summary>
public int AllowRecharge
{
get { return _allowrecharge; }
set { _allowrecharge = value; }
}
}
/// <summary>
/// 插件设置信息类
/// </summary>
public class PluginSetInfo
{
private string _partner;//合作者身份ID
private string _key;//交易安全检验码
private string _seller;//收款支付宝帐户
private int _allowrecharge;//是否允许账户充值
/// <summary>
/// 合作者身份ID
/// </summary>
public string Partner
{
get { return _partner; }
set { _partner = value; }
}
/// <summary>
/// 交易安全检验码
/// </summary>
public string Key
{
get { return _key; }
set { _key = value; }
}
/// <summary>
/// 收款支付宝帐户
/// </summary>
public string Seller
{
get { return _seller; }
set { _seller = value; }
}
/// <summary>
/// 是否允许账户充值
/// </summary>
public int AllowRecharge
{
get { return _allowrecharge; }
set { _allowrecharge = value; }
}
}
然后添加一个工具类PluginUtils来序列化和反序列化设置信息，代码如下：
/// <summary>
/// 插件工具类
/// </summary>
public class PluginUtils
{
private static object _locker = new object();//锁对象
private static PluginSetInfo _pluginsetinfo = null;//插件设置信息
private static string _plugindatafilepath = "/Plugins/BrnShop.PayPlugin.Alipay/PluginData.config";//数据文件路径
/// <summary>
///获得插件设置
/// </summary>
/// <returns></returns>
public static PluginSetInfo GetPluginSet()
{
if (_pluginsetinfo == null)
{
lock (_locker)
{
if (_pluginsetinfo == null)
{
_pluginsetinfo = (PluginSetInfo)IOHelper.DeserializeFromXML(typeof(PluginSetInfo), IOHelper.GetMapPath(_plugindatafilepath));
}
}
}
return _pluginsetinfo;
}
/// <summary>

就下来就是前台和后台实现了。首先是后台实现，对于后台我们只需要提供一个可供修改支付宝配置的子方法就行了，此子方法在上面讲解"IPlugin"接口时已经给出了它的调用方式。代码如下：
/// <summary>
/// 通知调用
/// </summary>
public ActionResult Notify()
{
SortedDictionary<string, string> sPara = AlipayCore.GetRequestPost();
if (sPara.Count > 0)//判断是否有带返回参数
{
bool verifyResult = AlipayNotify.Verify(sPara, Request.QueryString["notify_id"], Request.QueryString["sign"], AlipayConfig.SignType, AlipayConfig.Key, AlipayConfig.Code, AlipayConfig.VeryfyUrl, AlipayConfig.Partner);
if (verifyResult && (Request.QueryString["trade_status"] == "TRADE_FINISHED" || Request.QueryString["trade_status"] == "TRADE_SUCCESS"))//验证成功
{
int oid = TypeHelper.StringToInt(Request.QueryString["out_trade_no"]);//商户订单号
string tradeSN = Request.QueryString["trade_no"];//支付宝交易号
decimal tradeMoney = TypeHelper.StringToDecimal(Request.QueryString["total_fee"]);//交易金额
DateTime tradeTime = TypeHelper.StringToDateTime(Request.QueryString["gmt_payment"]);//交易时间
OrderInfo orderInfo = Orders.GetOrderByOid(oid);
if (orderInfo.PayMode == 1 && orderInfo.SurplusMoney > 0 && orderInfo.SurplusMoney <= tradeMoney)
{
Orders.PayOrder(oid, OrderState.Confirming, tradeSN);
OrderActions.CreateOrderAction(new OrderActionInfo()
{
Oid = oid,
Uid = orderInfo.Uid,
RealName = "本人",
AdminGid = 1,
AdminGTitle = "非管理员",
ActionType = (int)OrderActionType.Pay,
ActionTime = tradeTime,
ActionDes = "你使用支付宝支付订单成功，支付宝交易号为:" + tradeSN
});
}
return new EmptyResult();
}
else//验证失败
{
return new EmptyResult();
}
}
else
{
return new EmptyResult();
}
}
/// <summary>
/// 后台支付宝插件控制器类
/// </summary>
public class AdminAlipayController : BaseAdminController
{
/// <summary>
/// 配置
/// </summary>
[HttpGet]
[ChildActionOnly]
public ActionResult Config()
{
ConfigModel model = new ConfigModel();
model.Partner = PluginUtils.GetPluginSet().Partner;
model.Key = PluginUtils.GetPluginSet().Key;
model.Seller = PluginUtils.GetPluginSet().Seller;
model.AllowRecharge = PluginUtils.GetPluginSet().AllowRecharge;
return View("~/Plugins/BrnShop.PayPlugin.Alipay/Views/AdminAlipay/Config.cshtml", model);
}
/// <summary>
/// 配置
/// </summary>
[HttpPost]
public ActionResult Config(ConfigModel model)
{
if (ModelState.IsValid)
{
PluginSetInfo setting = new PluginSetInfo();
setting.Partner = model.Partner.Trim();
setting.Key = model.Key.Trim();
setting.Seller = model.Seller.Trim();
setting.AllowRecharge = model.AllowRecharge;
PluginUtils.SavePluginSet(setting);
}
return RedirectToAction("List", "Plugin", new RouteValueDictionary() { { "area", "Admin" }, { "Type", "1" } });
}
}
至于前台我们有3个方面需要去实现，第一个方面是返回调用动作方法，代码如下：
/// <summary>
/// 通知调用
/// </summary>
public ActionResult Notify()
{
SortedDictionary<string, string> sPara = AlipayCore.GetRequestPost();
if (sPara.Count > 0)//判断是否有带返回参数
{
bool verifyResult = AlipayNotify.Verify(sPara, Request.QueryString["notify_id"], Request.QueryString["sign"], AlipayConfig.SignType, AlipayConfig.Key, AlipayConfig.Code, AlipayConfig.VeryfyUrl, AlipayConfig.Partner);
if (verifyResult && (Request.QueryString["trade_status"] == "TRADE_FINISHED" || Request.QueryString["trade_status"] == "TRADE_SUCCESS"))//验证成功
{
int oid = TypeHelper.StringToInt(Request.QueryString["out_trade_no"]);//商户订单号
string tradeSN = Request.QueryString["trade_no"];//支付宝交易号
decimal tradeMoney = TypeHelper.StringToDecimal(Request.QueryString["total_fee"]);//交易金额
DateTime tradeTime = TypeHelper.StringToDateTime(Request.QueryString["gmt_payment"]);//交易时间
OrderInfo orderInfo = Orders.GetOrderByOid(oid);
if (orderInfo.PayMode == 1 && orderInfo.SurplusMoney > 0 && orderInfo.SurplusMoney <= tradeMoney)
{
Orders.PayOrder(oid, OrderState.Confirming, tradeSN);
OrderActions.CreateOrderAction(new OrderActionInfo()
{
Oid = oid,
Uid = orderInfo.Uid,
RealName = "本人",
AdminGid = 1,
AdminGTitle = "非管理员",
ActionType = (int)OrderActionType.Pay,
ActionTime = tradeTime,
ActionDes = "你使用支付宝支付订单成功，支付宝交易号为:" + tradeSN
});
}
return new EmptyResult();
}
else//验证失败
{
return new EmptyResult();
}
}
else
{
return new EmptyResult();
}
}
/// <summary>
/// 返回调用
/// </summary>
public ActionResult Return()
{
SortedDictionary<string, string> sPara = AlipayCore.GetRequestGet();
if (sPara.Count > 0)//判断是否有带返回参数
{
bool verifyResult = AlipayNotify.Verify(sPara, Request.QueryString["notify_id"], Request.QueryString["sign"], AlipayConfig.SignType, AlipayConfig.Key, AlipayConfig.Code, AlipayConfig.VeryfyUrl, AlipayConfig.Partner);
if (verifyResult && (Request.QueryString["trade_status"] == "TRADE_FINISHED" || Request.QueryString["trade_status"] == "TRADE_SUCCESS"))//验证成功
{
int oid = TypeHelper.StringToInt(Request.QueryString["out_trade_no"]);//商户订单号
string tradeSN = Request.QueryString["trade_no"];//支付宝交易号
decimal tradeMoney = TypeHelper.StringToDecimal(Request.QueryString["total_fee"]);//交易金额
DateTime tradeTime = TypeHelper.StringToDateTime(Request.QueryString["notify_time"]);//交易时间
OrderInfo orderInfo = Orders.GetOrderByOid(oid);
if (orderInfo.PayMode == 1 && orderInfo.SurplusMoney > 0 && orderInfo.SurplusMoney <= tradeMoney)
{
Orders.PayOrder(oid, OrderState.Confirming, tradeSN);
OrderActions.CreateOrderAction(new OrderActionInfo()
{
Oid = oid,
Uid = orderInfo.Uid,
RealName = "本人",
AdminGid = 1,
AdminGTitle = "非管理员",
ActionType = (int)OrderActionType.Pay,
ActionTime = tradeTime,
ActionDes = "你使用支付宝支付订单成功，支付宝交易号为:" + tradeSN
});
}
return RedirectToAction("PaySuccess", "Order", new RouteValueDictionary { { "oid", orderInfo.Oid } });
}
else//验证失败
{
return new EmptyResult();
}
}
else
{
return new EmptyResult();
}
}
第二个方面是通知调用动作方法，代码如下：
/// <summary>
/// 通知调用
/// </summary>
public ActionResult Notify()
{
SortedDictionary<string, string> sPara = AlipayCore.GetRequestPost();
if (sPara.Count > 0)//判断是否有带返回参数
{
bool verifyResult = AlipayNotify.Verify(sPara, Request.QueryString["notify_id"], Request.QueryString["sign"], AlipayConfig.SignType, AlipayConfig.Key, AlipayConfig.Code, AlipayConfig.VeryfyUrl, AlipayConfig.Partner);
if (verifyResult && (Request.QueryString["trade_status"] == "TRADE_FINISHED" || Request.QueryString["trade_status"] == "TRADE_SUCCESS"))//验证成功
{
int oid = TypeHelper.StringToInt(Request.QueryString["out_trade_no"]);//商户订单号
string tradeSN = Request.QueryString["trade_no"];//支付宝交易号
decimal tradeMoney = TypeHelper.StringToDecimal(Request.QueryString["total_fee"]);//交易金额
DateTime tradeTime = TypeHelper.StringToDateTime(Request.QueryString["gmt_payment"]);//交易时间
OrderInfo orderInfo = Orders.GetOrderByOid(oid);
if (orderInfo.PayMode == 1 && orderInfo.SurplusMoney > 0 && orderInfo.SurplusMoney <= tradeMoney)
{
Orders.PayOrder(oid, OrderState.Confirming, tradeSN);
OrderActions.CreateOrderAction(new OrderActionInfo()
{
Oid = oid,
Uid = orderInfo.Uid,
RealName = "本人",
AdminGid = 1,
AdminGTitle = "非管理员",
ActionType = (int)OrderActionType.Pay,
ActionTime = tradeTime,
ActionDes = "你使用支付宝支付订单成功，支付宝交易号为:" + tradeSN
});
}
return new EmptyResult();
}
else//验证失败
{
return new EmptyResult();
}
}
else
{
return new EmptyResult();
}
}
/// <summary>
/// 通知调用
/// </summary>
public ActionResult Notify()
{
SortedDictionary<string, string> sPara = AlipayCore.GetRequestPost();
if (sPara.Count > 0)//判断是否有带返回参数
{
bool verifyResult = AlipayNotify.Verify(sPara, Request.QueryString["notify_id"], Request.QueryString["sign"], AlipayConfig.SignType, AlipayConfig.Key, AlipayConfig.Code, AlipayConfig.VeryfyUrl, AlipayConfig.Partner);
if (verifyResult && (Request.QueryString["trade_status"] == "TRADE_FINISHED" || Request.QueryString["trade_status"] == "TRADE_SUCCESS"))//验证成功
{
int oid = TypeHelper.StringToInt(Request.QueryString["out_trade_no"]);//商户订单号
string tradeSN = Request.QueryString["trade_no"];//支付宝交易号
decimal tradeMoney = TypeHelper.StringToDecimal(Request.QueryString["total_fee"]);//交易金额
DateTime tradeTime = TypeHelper.StringToDateTime(Request.QueryString["gmt_payment"]);//交易时间
OrderInfo orderInfo = Orders.GetOrderByOid(oid);
if (orderInfo.PayMode == 1 && orderInfo.SurplusMoney > 0 && orderInfo.SurplusMoney <= tradeMoney)
{
Orders.PayOrder(oid, OrderState.Confirming, tradeSN);
OrderActions.CreateOrderAction(new OrderActionInfo()
{
Oid = oid,
Uid = orderInfo.Uid,
RealName = "本人",
AdminGid = 1,
AdminGTitle = "非管理员",
ActionType = (int)OrderActionType.Pay,
ActionTime = tradeTime,
ActionDes = "你使用支付宝支付订单成功，支付宝交易号为:" + tradeSN
});
}
return new EmptyResult();
}
else//验证失败
{
return new EmptyResult();
}
}
else
{
return new EmptyResult();
}
}
第三个方面是我们需要提供一个支付宝简介的视图文件，这个视图文件在顾客支付订单时给其展示一些支付宝的说明信息，此文件有以下几点要求：
- 文件名必须为"Show.cshtml"。
- 此文件必须位于插件项目的Views文件夹的顶层中。
- 此视图文件接收类型为OrderInfo的视图模型对象。
这个视图文件在BrnShop.Web项目的支付展示视图文件PayShowModel.cshtml中调用，调用方式如下：
@Html.Partial(Model.ShowView, Model.OrderInfo)
至此支付宝插件开发完成，至于其它类型的插件开发也都是大同小异。
PS：最后附上一张BrnShop开启NOSQL前后的性能对比图，以商品详细页面为例：
开启NOSQL前：
开启NOSQL后：
可见性能提升还是很明显的。
