爲了方便擴展制定支付寶回調接口

public interface IReturnHandler
{
/// <summary>
/// 處理Returl_url回調請求
/// </summary>
/// <param name="properties">支付寶相關參數</param>
/// <param name="customs">自定義參數</param>
void Return(System.Collections.Specialized.NameValueCollection properties, IList<string> customs);
/// <summary>
/// 處理Notify_url回調請求
/// </summary>
/// <param name="properties">支付寶相關參數</param>
/// <param name="customs">自定義參數</param>
void Notify(System.Collections.Specialized.NameValueCollection properties, IList<string> customs);
/// <summary>
/// 支付寶處理錯誤回調請求
/// </summary>
/// <param name="properties">支付寶相關參數</param>
/// <param name="customs">自定義參數</param>
/// <param name="responsetext">結果內容</param>
void OnError(System.Collections.Specialized.NameValueCollection properties, IList<string> customs,string responsetext);
/// <summary>
/// 合作商ID
/// </summary>
string Partner
{
get;
}
/// <summary>
/// 加密Key
/// </summary>
string Key
{
get;
}
/// <summary>
/// 賣家郵件地址
/// </summary>
string Seller_Email
{
get;
}
}
重新實現AliPay類
/// <summary>
/// 支付寶虛擬貨幣支付
/// </summary>
public class AliPay
{
/// <summary>
/// 構造虛擬貨幣支付對象
/// </summary>
/// <param name="subject">商品名稱</param>
/// <param name="body">商品描述</param>
/// <param name="total_fee">總金額</param>
public AliPay(string subject, string body, decimal total_fee
,string returnurl)
{
Gateway = Untity.Service_Ulr;
Service = "create_direct_pay_by_user";
Sing_Type = Untity.Sing_Type;
Payment_Type = "1";
Subject = subject;
Body = body;
Total_Fee = total_fee;
Return_Url = returnurl;
Notify_Url = returnurl;
}
public string Notify_Url
{
get;
set;
}
public string Buyer_Id
{
get;
set;
}
public void Execute<T>(params string[] customparams) where T:IReturnHandler,new()
{
System.DateTime currentTime = new System.DateTime();
currentTime = System.DateTime.Now;
string out_trade_no = currentTime.ToString("g");
Out_Trade_No = out_trade_no.Replace("-", "");
Out_Trade_No = Out_Trade_No.Replace(":", "");
Out_Trade_No = Out_Trade_No.Replace(" ", "");
//返回支付Url；
System.Web.HttpContext.Current.Response.Redirect(parameter.ToString());
}
}
Alipay的代碼就貼部分出來，具體代碼下載源碼可以得到。

Execute方法是用調用支付寶接口，T泛型參數主要描述支付寶回調後用那個IReturnHandler的實現者來處理；customparams就是用戶自定義的參數可以是多個，注意參數內容過多生成Returl_url過長會導致支付寶處理錯誤。

接收支付寶回調的HttpHandler

由於把回調處理類型和自定義參數放在Return_utl裏，所以必須要實現一個HttpHandler來進行相關請求接收。

public class ReturnHandler:System.Web.IHttpHandler
{
#region IHttpHandler 成員
public bool IsReusable
{
get { return false; }
}
public String Get_Http(String a_strUrl, int timeout)
{
string strResult;
try
{
HttpWebRequest myReq = (HttpWebRequest)HttpWebRequest.Create(a_strUrl);
myReq.Timeout = timeout;
HttpWebResponse HttpWResp = (HttpWebResponse)myReq.GetResponse();
Stream myStream = HttpWResp.GetResponseStream();
StreamReader sr = new StreamReader(myStream, Encoding.Default);
StringBuilder strBuilder = new StringBuilder();
while (-1 != sr.Peek())
{
strBuilder.Append(sr.ReadLine());
}
strResult = strBuilder.ToString();
}
catch (Exception exp)
{
strResult = "錯誤：" + exp.Message;
}
return strResult;
}
public void ProcessRequest(System.Web.HttpContext context)
{
string requesturl = context.Server.UrlDecode(context.Request.Path);
string alipayNotifyURL = Untity.Service_Ulr;
string urltype=System.IO.Path.GetFileName(requesturl).Substring(0, 1).ToLower();
MatchCollection matchs = Regex.Matches(requesturl, @"_([0-9a-zA-Z/%=]+)");
string TypeName = System.Text.Encoding.ASCII.GetString(Convert.FromBase64String(matchs[0].Groups[1].Value));
IReturnHandler handler = (IReturnHandler)Activator.CreateInstance(Type.GetType(TypeName));
IList<string> paramsdata = new List<string>();
for (int k = 1; k < matchs.Count; k++)
{
paramsdata.Add(matchs[k].Groups[1].Value);
}
string partner = handler.Partner;
string key = handler.Key;
NameValueCollection payResultData;
if (urltype == "r")
{
payResultData = context.Request.QueryString;
}
else
{
payResultData = context.Request.Form;
}
alipayNotifyURL = alipayNotifyURL + "service=notify_verify" + "&partner=" + partner + "¬ify_id=" + payResultData["notify_id"];
string responseTxt = Get_Http(alipayNotifyURL, 120000);
int i;
String[] requestarr = payResultData.AllKeys;
//進行排序；
string[] Sortedstr = Untity.BubbleSort(requestarr);
//構造待md5摘要字符串；
string prestr = "";
for (i = 0; i < Sortedstr.Length; i++)
{
if (context.Request.Form[Sortedstr] != "" && Sortedstr != "sign" && Sortedstr != "sign_type")
{
if (i == Sortedstr.Length - 1)
{
prestr = prestr + Sortedstr + "=" + payResultData[Sortedstr];
}
else
{
prestr = prestr + Sortedstr + "=" + payResultData[Sortedstr] + "&";
}
}
}
prestr = prestr + key;
string mysign =Untity.GetMD5(prestr);
string sign = payResultData["sign"];
if (responseTxt == "true" && mysign == sign) //驗證支付發過來的消息，簽名是否正確
{
string status = payResultData["trade_status"];
if (status == "TRADE_FINISHED")// WAIT_SELLER_SEND_GOODS 判斷支付狀態（文檔中有枚舉表可以參考）
{
//更新自己數據庫的訂單語句，請自己填寫一下
if (urltype == "r")
{
handler.Return(payResultData, paramsdata);
}
else
{
handler.Notify(payResultData, paramsdata);
}
}
}
else
{
handler.OnError(payResultData, paramsdata, responseTxt);
}
}
#endregion
}
到這裏封裝完成。
