c# 支付宝查单补单
谁谁谁手机那边支付宝支付成功扣钱了，游戏里面却没有充钱，唯有写个补单程序。
首先要查单，查单接口（交易信息查询接口：https://mapi.alipay.com/gateway.do），服务名称：single_trade_query。
这个接口权限要到支付宝联系客服开通
用4点积分去CSDN下载了个demo，我共享吧：https://yunpan.cn/cqavWFY3Tccua 访问密码 2860
demo是web形式的，我要的是winfrom效果，在服务器每隔几分钟就运行一次，实现自动补单效果。
主要代码：
DataControl gData = new DataControl(); try { string url = "https://mapi.alipay.com/gateway.do?"; //查询未付款的支付宝订单 DataTable dt = gData.GetDataTable("select .... from ...."); string post_data = ""; string requestData = ""; foreach (DataRow r in dt.Rows) { //把请求参数打包成数组 SortedDictionary<string, string> sParaTemp = new SortedDictionary<string, string>(); sParaTemp.Add("partner", Config.Partner); sParaTemp.Add("_input_charset", Config.Input_charset.ToLower()); sParaTemp.Add("service", "single_trade_query"); sParaTemp.Add("trade_no", ""); sParaTemp.Add("out_trade_no", r["OrderID"].ToString()); post_data = AlipaySubmit.BuildRequest(sParaTemp); requestData = gData.CallWebApi(url + post_data); QueryOrder queryorder = new QueryOrder(); queryorder = InsQueryOrder(requestData); if (queryorder.is_success == "T") { if (queryorder.trade_status == "TRADE_SUCCESS") { WriteReturnZFBDetail(queryorder); FilliedOnline(queryorder.out_trade_no); } } } } catch(Exception ex) { }
post_data是api需要的参数，得到的效果是这样的：
service=single_trade_query&sign=签名&partner=支付宝合作身份者ID&out_trade_no=商户订单号&sign_type=MD5
可以直接浏览器这样访问：
https://mapi.alipay.com/gateway.do?service=single_trade_query&sign=签名&partner=支付宝合作身份者ID&out_trade_no=商户订单号&sign_type=MD5
结果：
前提是准备好了自己的相关数据。
requestData = gData.CallWebApi(url + post_data);
这个函数可以得到API返回来的数据，该API返回数据格式是xml，数据是这样的：
<?xml version="1.0" encoding="utf-8"?> <alipay> <is_success>T</is_success> <request> <param name="trade_no">2010073000030344</param> <param name="service">single_trade_query</param> <param name="partner">2088002007018916</param> </request> <response> <trade> <body>合同催款通知</body> <buyer_email>[email protected]</buyer_email> <buyer_id>2088102002723445</buyer_id> <discount>0.00</discount> <gmt_create>2010-07-30 12:26:33</gmt_create> <gmt_last_modified_time>2010-07-30 12:30:29 </gmt_last_modified_time> <gmt_payment>2010-07-30 12:30:29</gmt_payment> <is_total_fee_adjust>F</is_total_fee_adjust> <out_trade_no>1280463992953</out_trade_no> <payment_type>1</payment_type> <price>1.00</price> <quantity>1</quantity> <seller_email>[email protected]</seller_email> <seller_id>2088002007018916</seller_id> <subject>合同催款通知</subject> <total_fee>1.00</total_fee> <trade_no>2010073000030344</trade_no> <trade_status>TRADE_FINISHED</trade_status> <use_coupon>F</use_coupon> </trade> </response> <sign>56ae9c3286886f76e57e0993625c71fe</sign> <sign_type>MD5</sign_type> </alipay>
访问接口并返回接口数据的函数CallWebApi：
public string CallWebApi(string url) { string html = ""; try { HttpWebRequest req = WebRequest.Create(url) as HttpWebRequest; req.ContentType = "multipart/form-data"; req.Accept = "*/*"; req.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)"; req.Timeout = 30000;//30秒连接不成功就中断 req.Method = "GET"; HttpWebResponse response = req.GetResponse() as HttpWebResponse; using (StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8)) { html = sr.ReadToEnd(); } } catch { } return html; }
QueryOrder类：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.Serialization; namespace AlipayCheck { [DataContract] public class QueryOrder { /// <summary> /// 是否成功,T代表成功,F代表失败 /// </summary> public string is_success { get; set; } /// <summary> /// 签名 /// </summary> public string sign { get; set; } /// <summary> /// 签名方式只支持DSA、RSA、MD5 /// </summary> public string sign_type { get; set; } /// <summary> /// 只有当查询交易失败后，才返回错误代码 /// </summary> public string error { get; set; } /// <summary> /// 买家支付宝账号 /// </summary> public string buyer_email { get; set; } /// <summary> /// 买家支付宝账号对应的支付宝唯一用户号 /// </summary> public string buyer_id { get; set; } /// <summary> /// 交易状态 /// </summary> public string trade_status { get; set; } /// <summary> /// 交易金额是否调整过 /// </summary> public string is_total_fee_adjust { get; set; } /// <summary> /// 商户网站唯一订单号 /// </summary> public string out_trade_no { get; set; } /// <summary> /// 支付宝交易号 /// </summary> public string trade_no { get; set; } /// <summary> /// 商品名称 /// </summary> public string subject { get; set; } /// <summary> /// 交易冻结状态 /// </summary> public string flag_trade_locked { get; set; } /// <summary> /// 商品描述 /// </summary> public string body { get; set; } /// <summary> /// 交易创建时间 /// </summary> public string gmt_create { get; set; } /// <summary> /// 卖家的支付宝账号 /// </summary> public string seller_email { get; set; } /// <summary> /// 卖家支付宝账号对应的支付宝唯一用户号 /// </summary> public string seller_id { get; set; } /// <summary> /// 交易总金额 /// </summary> public string total_fee { get; set; } /// <summary> /// 商品单价 /// </summary> public string price { get; set; } /// <summary> /// 购买数量 /// </summary> public string quantity { get; set; } /// <summary> /// 邮费 /// </summary> public string logistics_fee { get; set; } /// <summary> /// 红包折扣 /// </summary> public string coupon_discount { get; set; } /// <summary> /// 是否使用过红包 /// </summary> public string use_coupon { get; set; } /// <summary> /// 折扣 /// </summary> public string discount { get; set; } /// <summary> /// 退款状态 /// </summary> public string refund_status { get; set; } /// <summary> /// 物流状态 /// </summary> public string logistics_status { get; set; } /// <summary> /// 交易附加状态 /// </summary> public string additional_trade_status { get; set; } /// <summary> /// 交易最近一次修改时间 /// </summary> public string gmt_last_modified_time { get; set; } /// <summary> /// 付款时间 /// </summary> public string gmt_payment { get; set; } /// <summary> /// 卖家发货时间 /// </summary> public string gmt_send_goods { get; set; } /// <summary> /// 退款时间 /// </summary> public string gmt_refund { get; set; } /// <summary> /// 主超时时间 /// </summary> public string time_out { get; set; } /// <summary> /// 交易关闭时间，只有为TRADE_CLOSE状态的交易才存在此时间 /// </summary> public string gmt_close { get; set; } /// <summary> /// 物流状态更新时间 /// </summary> public string gmt_logistics_modify { get; set; } /// <summary> /// 主超时间类型 /// </summary> public string time_out_type { get; set; } /// <summary> /// 退款金额 /// </summary> public string refund_fee { get; set; } /// <summary> /// 退款流程 /// </summary> public string refund_flow_type { get; set; } /// <summary> /// 退款唯一标识号 /// </summary> public string refund_id { get; set; } /// <summary> /// 退现金金额 /// </summary> public string refund_cash_fee { get; set; } /// <summary> /// 退红包金额 /// </summary> public string refund_coupon_fee { get; set; } /// <summary> /// 退积分金额 /// </summary> public string refund_agent_pay_fee { get; set; } /// <summary> /// 使用红包的金额 /// </summary> public string coupon_used_fee { get; set; } /// <summary> /// 累计的已经退款金额 /// </summary> public string to_buyer_fee { get; set; } /// <summary> /// 累计的已打款给买家的金额 /// </summary> public string to_seller_fee { get; set; } /// <summary> /// 资金单据列表，xml格式，由一个或多个FundBillDetail标签组成。 /// </summary> public string fund_bill_list { get; set; } /// <summary> /// 收款类型 /// </summary> public string payment_type { get; set; } /// <summary> /// 交易的创建人角色 /// </summary> public string operator_role { get; set; } /// <summary> /// 接口类型 /// </summary> public string service { get; set; } } }
获取xml数据塞入queryorder类：
private static QueryOrder InsQueryOrder(string requestData) { QueryOrder queryorder = new QueryOrder(); XmlDocument xmldoc = new XmlDocument(); xmldoc.LoadXml(requestData); //获取节点列表 queryorder.service = "single_trade_query"; XmlNodeList topM = xmldoc.SelectNodes("alipay"); foreach (XmlElement element in topM) { queryorder.is_success = element.GetElementsByTagName("is_success")[0].InnerText; if (queryorder.is_success == "F") return queryorder; queryorder.sign = element.GetElementsByTagName("sign")[0].InnerText; queryorder.sign_type = element.GetElementsByTagName("sign_type")[0].InnerText; } topM = xmldoc.SelectNodes("alipay/response/trade"); foreach (XmlElement element in topM) { queryorder.buyer_email = element.GetElementsByTagName("buyer_email")[0].InnerText; queryorder.buyer_id = element.GetElementsByTagName("buyer_id")[0].InnerText; queryorder.discount = element.GetElementsByTagName("discount")[0].InnerText; queryorder.flag_trade_locked = element.GetElementsByTagName("flag_trade_locked")[0].InnerText; queryorder.gmt_create = element.GetElementsByTagName("gmt_create")[0].InnerText; queryorder.gmt_last_modified_time = element.GetElementsByTagName("gmt_last_modified_time")[0].InnerText; queryorder.gmt_payment = element.GetElementsByTagName("gmt_payment")[0].InnerText; queryorder.is_total_fee_adjust = element.GetElementsByTagName("is_total_fee_adjust")[0].InnerText; queryorder.operator_role = element.GetElementsByTagName("operator_role")[0].InnerText; queryorder.out_trade_no = element.GetElementsByTagName("out_trade_no")[0].InnerText; queryorder.payment_type = element.GetElementsByTagName("payment_type")[0].InnerText; queryorder.price = element.GetElementsByTagName("price")[0].InnerText; queryorder.quantity = element.GetElementsByTagName("quantity")[0].InnerText; queryorder.seller_email = element.GetElementsByTagName("seller_email")[0].InnerText; queryorder.seller_id = element.GetElementsByTagName("seller_id")[0].InnerText; queryorder.subject = element.GetElementsByTagName("subject")[0].InnerText; queryorder.time_out = element.GetElementsByTagName("time_out")[0].InnerText; queryorder.time_out_type = element.GetElementsByTagName("time_out_type")[0].InnerText; queryorder.to_buyer_fee = element.GetElementsByTagName("to_buyer_fee")[0].InnerText; queryorder.to_seller_fee = element.GetElementsByTagName("to_seller_fee")[0].InnerText; queryorder.total_fee = element.GetElementsByTagName("total_fee")[0].InnerText; queryorder.trade_no = element.GetElementsByTagName("trade_no")[0].InnerText; queryorder.trade_status = element.GetElementsByTagName("trade_status")[0].InnerText; queryorder.use_coupon = element.GetElementsByTagName("use_coupon")[0].InnerText; } return queryorder; } }
然后可以根据订单状态写自己的业务逻辑了：
if (queryorder.is_success == "T") { if (queryorder.trade_status == "TRADE_SUCCESS") { WriteReturnZFBDetail(queryorder); FilliedOnline(queryorder.out_trade_no); } }
