支付宝的接口调用很不方便,刚做好一个封装,实现了虚拟交易和实物交易。
解决方案中有三个项目以及NDoc生成的文档,简单的序列图:CommonAliPay,封装的支付宝接口。
TestAli,asp.net的测试项目
TestCommonAliPay,Nunit的测试项目。

调用方法:
1、引入CommonAliPay.dll
2、实现支付宝服务接口的方法调用方式:
AliPay ap = new AliPay(); string key = "";//填写自己的key string partner = "";//填写自己的Partner StandardGoods bp = new StandardGoods("trade_create_by_buyer", partner, key, "MD5", "卡2", Guid.NewGuid().ToString(), 2.551m, 1, "[email protected]", "[email protected]" , "EMS", 25.00m, "BUYER_PAY","1"); bp.Notify_Url = "http://203.86.79.185/ali/notify.aspx"; ap.CreateStandardTrade("https://www.alipay.com/cooperate/gateway.do", bp, this);
上面是通用的调用方式。
下面是只支持虚拟货物的方式:
string key = "";//填写自己的key string partner = "";//填写自己的Partner AliPay ap = new AliPay(); DigitalGoods bp = new DigitalGoods("create_digital_goods_trade_p", partner, key, "MD5", "卡2", Guid.NewGuid().ToString(), 2.551m, 1, "[email protected]", "[email protected]"); bp.Notify_Url = "http://203.86.79.185/ali/notify.aspx"; ap.CreateDigitalTrade("https://www.alipay.com/cooperate/gateway.do", bp, this);
3、实现支付宝通知接口方法的调用(支持虚拟和实物):
protected void Page_Load(object sender, EventArgs e) { string key = "";//填写自己的key string partner = "";//填写自己的Partner AliPay ap = new AliPay(); string notifyid = Request.Form["notify_id"]; Verify v = new Verify("notify_verify", partner, notifyid); ap.WaitSellerSendGoods+=new AliPay.ProcessNotifyEventHandler(ap_WaitSellerSendGoods); ap.WaitBuyerPay += new AliPay.ProcessNotifyEventHandler(ap_WaitBuyerPay); ap.ProcessNotify(this, "https://www.alipay.com/cooperate/gateway.do",key,v, "utf-8"); } void ap_WaitBuyerPay(object sender, NotifyEventArgs e) { // //加入自己的处理逻辑 Log4net.log.Error("wait buyer pay fire"); } private void ap_WaitSellerSendGoods(object sender, NotifyEventArgs e) { //加入自己的处理逻辑 Log4net.log.Error("WaitSellerSendGoods fire"); }
支付宝的交易状态都被定义成了类似名称的事件。
部分源代码解析:
1、解析Forms集合到NotifyEventArgs类,因为后面此类的数据要用来做MD5Sign,所以所有值类型,不能存在初始值,如:int的0等。因此用Nullable范型。
private NotifyEventArgs ParseNotify(NameValueCollection nv, object obj) { PropertyInfo[] propertyInfos = obj.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance); foreach (PropertyInfo pi in propertyInfos) { string v = nv.Get(pi.Name.ToLower()); if (v != null) { if (pi.PropertyType == typeof(string)) { pi.SetValue(obj, v, null); } else if (pi.PropertyType == typeof(int?)) { pi.SetValue(obj, int.Parse(v), null); } else if (pi.PropertyType == typeof(decimal?)) { pi.SetValue(obj, decimal.Parse(v), null); } else if (pi.PropertyType == typeof(DateTime?)) { pi.SetValue(obj, DateTime.Parse(v), null); } else if (pi.PropertyType == typeof(bool)) { pi.SetValue(obj, bool.Parse(v), null); } else { //转型失败会抛出异常 pi.SetValue(obj, v, null); } } } return (NotifyEventArgs)obj; }
2、从类型中获取排序后的参数
/**//// <summary> /// 获取排序后的参数 /// </summary> /// <param name="obj"></param> /// <returns></returns> private SortedList<string,string> GetParam(object obj) { PropertyInfo[] propertyInfos = obj.GetType().GetProperties(BindingFlags.Public|BindingFlags.Instance); SortedList<string, string> sortedList = new SortedList<string, string>(StringComparer.CurrentCultureIgnoreCase); foreach (PropertyInfo pi in propertyInfos) { if (pi.GetValue(obj, null) != null) { if (pi.Name == "Sign" || pi.Name == "Sign_Type") { continue; } sortedList.Add(pi.Name.ToLower(), pi.GetValue(obj, null).ToString()); } } return sortedList; }
3、从SortedList中产生参数
private string GetUrlParam(SortedList<string, string> sortedList,bool isEncode) { StringBuilder param = new StringBuilder(); StringBuilder encodeParam = new StringBuilder(); if (isEncode == false) { foreach (KeyValuePair<string, string> kvp in sortedList) { string t = string.Format("{0}={1}", kvp.Key, kvp.Value); param.Append(t + "&"); } return param.ToString().TrimEnd('&'); } else { foreach (KeyValuePair<string, string> kvp in sortedList) { string et = string.Format("{0}={1}", HttpUtility.UrlEncode(kvp.Key), HttpUtility.UrlEncode(kvp.Value)); encodeParam.Append(et + "&"); } return encodeParam.ToString().TrimEnd('&'); } }

因为时间很紧,有些地方还不完善,大家提出意见,有时间我会修改的
