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:
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:
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); }
成员比较多,我们分类来看就清晰了:
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) private string _friendlyname = "";//插件友好名称 private string _classfullname = "";//插件控制器 private string _folder = "";//插件目录 private string _description = "";//插件描述 private int _type = 0;//插件类型(0代表开放授权插件,1代表支付插件,2代表配送插件) private string _author = "";//插件作者 private string _version = "";//插件版本 private string _supversion = "";//插件支持的BrnShop版本 private int _displayOrder = 0;//插件顺序 private int _isdefault = 0;//是否是默认插件 /// <summary> /// 插件系统名称 /// </summary> public string SystemName { get { return _systemname; } set { _systemname = value; } } /// <summary> /// 插件友好名称 /// </summary> public string FriendlyName { get { return _friendlyname; } set { _friendlyname = value; } } /// <summary> /// 插件类型名称 /// </summary> public string ClassFullName { get { return _classfullname; } set { _classfullname = value; } } /// <summary> /// 插件目录 /// </summary> public string Folder { get { return _folder; } set { _folder = value; } } /// <summary> /// 插件描述 /// </summary> public string Description { get { return _description; } set { _description = value; } } /// <summary> /// 插件类型(0代表开放授权插件,1代表支付插件,2代表配送插件) /// </summary> public int Type { get { return _type; } set { _type = value; } } /// <summary> /// 插件作者 /// </summary> public string Author { get { return _author; } set { _author = value; } } /// <summary> /// 插件版本 /// </summary> public string Version { get { return _version; } set { _version = value; } } /// <summary> /// 插件支持的BrnShop版本 /// </summary> public string SupVersion { get { return _supversion; } set { _supversion = value; } } /// <summary> /// 插件顺序 /// </summary> public int DisplayOrder { get { return _displayOrder; } set { _displayOrder = value; } } /// <summary> /// 是否是默认插件 /// </summary> public int IsDefault { get { return _isdefault; } set { _isdefault = value; } } /// <summary> /// 插件实例 /// </summary> private IPlugin _instance = null; /// <summary> /// 插件实例 /// </summary> [XmlIgnoreAttribute] public IPlugin Instance { get { if (_instance == null) { try { _instance = (IPlugin)Activator.CreateInstance(System.Type.GetType(ClassFullName, false, true)); } catch (Exception ex) { throw new BSPException("创建插件:" + _classfullname + "的实例失败", ex); } } return _instance; } } public int CompareTo(object obj) { PluginInfo info = (PluginInfo)obj; if (this.DisplayOrder > info.DisplayOrder) return 1; else if (this.DisplayOrder < info.DisplayOrder) return -1; else return 0; } }
接下来我们定义一个类PluginService,并实现接口IPayPlugin,代码如下:
/// <summary> /// 插件服务类 /// </summary> public class PluginService : IPayPlugin { /// <summary> /// 插件配置控制器 /// </summary> /// <value></value> public string ConfigController { get { return "AdminAlipay"; } } /// <summary> /// 插件配置动作方法 /// </summary> /// <value></value> public string ConfigAction { get { return "Config"; } } /// <summary> /// 插件配置路由数据 /// </summary> /// <value></value> public RouteValueDictionary ConfigRouteValues { get { return new RouteValueDictionary() { { "area", "Admin" } }; } } /// <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> /// <value></value> public int PayMode { get { return 1; } } /// <summary> /// 是否允许账户充值(只对在线付款有效) /// </summary> /// <value></value> public bool AllowRecharge { get { return PluginUtils.GetPluginSet().AllowRecharge == 1; } } /// <summary> /// 支付返回控制器 /// </summary> /// <value></value> public string ReturnController { get { return "Alipay"; } } /// <summary> /// 支付返回动作方法 /// </summary> /// <value></value> public string ReturnAction { get { return "Return"; } } /// <summary> /// 支付返回路由数据 /// </summary> /// <value></value> public RouteValueDictionary ReturnRouteValues { get { return null; } } /// <summary> /// 支付通知控制器 /// </summary> /// <value></value> public string NotifyController { get { return "Alipay"; } } /// <summary> /// 支付通知动作方法 /// </summary> /// <value></value> public string NotifyAction { get { return "Notify"; } } /// <summary> /// 支付通知路由数据 /// </summary> /// <value></value> public RouteValueDictionary NotifyRouteValues { get { return null; } } /// <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> public decimal GetPayFee(decimal productAmount, DateTime buyTime, PartUserInfo partUserInfo) { return 0M; } /// <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="notifyUrl">通知url</param> /// <param name="returnUrl">返回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> public string GetRequestUrl(string notifyUrl, string returnUrl, PluginInfo pluginInfo, PartUserInfo partUserInfo, OrderInfo orderInfo) { //支付类型,必填,不能修改 string paymentType = "1"; //服务器异步通知页面路径,需http://格式的完整路径,不能加?id=123这类自定义参数 notifyUrl = string.Format("http://{0}{1}", BSPConfig.ShopConfig.SiteUrl, notifyUrl); //页面跳转同步通知页面路径,需http://格式的完整路径,不能加?id=123这类自定义参数,不能写成http://localhost/ returnUrl = string.Format("http://{0}{1}", BSPConfig.ShopConfig.SiteUrl, returnUrl); //收款支付宝帐户 string sellerEmail = AlipayConfig.Seller; //合作者身份ID string partner = AlipayConfig.Partner; //交易安全检验码 string key = AlipayConfig.Key; //商户订单号 string outTradeNo = orderInfo.Oid.ToString(); //订单名称 string subject = ""; //付款金额 string totalFee = orderInfo.SurplusMoney.ToString(); //订单描述 string body = ""; //防钓鱼时间戳,若要使用请调用类文件submit中的query_timestamp函数 string anti_phishing_key = ""; //客户端的IP地址,非局域网的外网IP地址,如:221.0.0.1 string exter_invoke_ip = ""; //把请求参数打包成数组 SortedDictionary<string, string> sParaTemp = new SortedDictionary<string, string>(); sParaTemp.Add("partner", partner); sParaTemp.Add("_input_charset", key); sParaTemp.Add("service", "create_direct_pay_by_user"); sParaTemp.Add("payment_type", paymentType); sParaTemp.Add("notify_url", notifyUrl); sParaTemp.Add("return_url", returnUrl); sParaTemp.Add("seller_email", sellerEmail); sParaTemp.Add("out_trade_no", outTradeNo); sParaTemp.Add("subject", subject); sParaTemp.Add("total_fee", totalFee); sParaTemp.Add("body", body); sParaTemp.Add("anti_phishing_key", anti_phishing_key); sParaTemp.Add("exter_invoke_ip", exter_invoke_ip); return AlipaySubmit.BuildRequestUrl(sParaTemp, AlipayConfig.Gateway, AlipayConfig.InputCharset, AlipayConfig.SignType, AlipayConfig.Key, AlipayConfig.Code); } }
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; } } }
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> /// 保存插件设置到数据数据文件中 /// </summary> public static void SavePluginSet(PluginSetInfo pluginSetInfo) { lock (_locker) { IOHelper.SerializeToXml(pluginSetInfo, IOHelper.GetMapPath(_plugindatafilepath)); _pluginsetinfo = null; AlipayConfig.ReSet(); } } }
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> /// 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> /// 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(); } }
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:
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。
