誰誰誰手機那邊支付寶支付成功扣錢了，游戲里面卻沒有充錢，唯有寫個補單程序。
首先要查單，查單接口（交易信息查詢接口：https://mapi.alipay.com/gateway.do），服務名稱：single_trade_query。
這個接口權限要到支付寶聯系客服開通
用4點積分去CSDN下載了個demo，我共享吧：https://yunpan.cn/cqavWFY3Tccua 訪問密碼 2860
demo是web形式的，我要的是winfrom效果，在服務器每隔幾分鍾就運行一次，實現自動補單效果。
主要代碼：
DataControl gData = new DataControl(); try { string url = "https://mapi.alipay.com/gateway.do?"; //查詢未付款的支付寶訂單 DataTable dt = gData.GetDataTable("select .... from ...."); string post_data = ""; string requestData = ""; foreach (DataRow r in dt.Rows) { //把請求參數打包成數組 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需要的參數，得到的效果是這樣的：
service=single_trade_query&sign=簽名&partner=支付寶合作身份者ID&out_trade_no=商戶訂單號&sign_type=MD5
可以直接瀏覽器這樣訪問：
https://mapi.alipay.com/gateway.do?service=single_trade_query&sign=簽名&partner=支付寶合作身份者ID&out_trade_no=商戶訂單號&sign_type=MD5
結果：
前提是准備好了自己的相關數據。
requestData = gData.CallWebApi(url + post_data);
這個函數可以得到API返回來的數據，該API返回數據格式是xml，數據是這樣的：
<?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>ltrade008@alitest.com</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>chao.chenc1@alipay.com</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>
訪問接口並返回接口數據的函數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秒連接不成功就中斷 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類：
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代表失敗 /// </summary> public string is_success { get; set; } /// <summary> /// 簽名 /// </summary> public string sign { get; set; } /// <summary> /// 簽名方式只支持DSA、RSA、MD5 /// </summary> public string sign_type { get; set; } /// <summary> /// 只有當查詢交易失敗后，才返回錯誤代碼 /// </summary> public string error { get; set; } /// <summary> /// 買家支付寶賬號 /// </summary> public string buyer_email { get; set; } /// <summary> /// 買家支付寶賬號對應的支付寶唯一用戶號 /// </summary> public string buyer_id { get; set; } /// <summary> /// 交易狀態 /// </summary> public string trade_status { get; set; } /// <summary> /// 交易金額是否調整過 /// </summary> public string is_total_fee_adjust { get; set; } /// <summary> /// 商戶網站唯一訂單號 /// </summary> public string out_trade_no { get; set; } /// <summary> /// 支付寶交易號 /// </summary> public string trade_no { get; set; } /// <summary> /// 商品名稱 /// </summary> public string subject { get; set; } /// <summary> /// 交易凍結狀態 /// </summary> public string flag_trade_locked { get; set; } /// <summary> /// 商品描述 /// </summary> public string body { get; set; } /// <summary> /// 交易創建時間 /// </summary> public string gmt_create { get; set; } /// <summary> /// 賣家的支付寶賬號 /// </summary> public string seller_email { get; set; } /// <summary> /// 賣家支付寶賬號對應的支付寶唯一用戶號 /// </summary> public string seller_id { get; set; } /// <summary> /// 交易總金額 /// </summary> public string total_fee { get; set; } /// <summary> /// 商品單價 /// </summary> public string price { get; set; } /// <summary> /// 購買數量 /// </summary> public string quantity { get; set; } /// <summary> /// 郵費 /// </summary> public string logistics_fee { get; set; } /// <summary> /// 紅包折扣 /// </summary> public string coupon_discount { get; set; } /// <summary> /// 是否使用過紅包 /// </summary> public string use_coupon { get; set; } /// <summary> /// 折扣 /// </summary> public string discount { get; set; } /// <summary> /// 退款狀態 /// </summary> public string refund_status { get; set; } /// <summary> /// 物流狀態 /// </summary> public string logistics_status { get; set; } /// <summary> /// 交易附加狀態 /// </summary> public string additional_trade_status { get; set; } /// <summary> /// 交易最近一次修改時間 /// </summary> public string gmt_last_modified_time { get; set; } /// <summary> /// 付款時間 /// </summary> public string gmt_payment { get; set; } /// <summary> /// 賣家發貨時間 /// </summary> public string gmt_send_goods { get; set; } /// <summary> /// 退款時間 /// </summary> public string gmt_refund { get; set; } /// <summary> /// 主超時時間 /// </summary> public string time_out { get; set; } /// <summary> /// 交易關閉時間，只有為TRADE_CLOSE狀態的交易才存在此時間 /// </summary> public string gmt_close { get; set; } /// <summary> /// 物流狀態更新時間 /// </summary> public string gmt_logistics_modify { get; set; } /// <summary> /// 主超時間類型 /// </summary> public string time_out_type { get; set; } /// <summary> /// 退款金額 /// </summary> public string refund_fee { get; set; } /// <summary> /// 退款流程 /// </summary> public string refund_flow_type { get; set; } /// <summary> /// 退款唯一標識號 /// </summary> public string refund_id { get; set; } /// <summary> /// 退現金金額 /// </summary> public string refund_cash_fee { get; set; } /// <summary> /// 退紅包金額 /// </summary> public string refund_coupon_fee { get; set; } /// <summary> /// 退積分金額 /// </summary> public string refund_agent_pay_fee { get; set; } /// <summary> /// 使用紅包的金額 /// </summary> public string coupon_used_fee { get; set; } /// <summary> /// 累計的已經退款金額 /// </summary> public string to_buyer_fee { get; set; } /// <summary> /// 累計的已打款給買家的金額 /// </summary> public string to_seller_fee { get; set; } /// <summary> /// 資金單據列表，xml格式，由一個或多個FundBillDetail標簽組成。 /// </summary> public string fund_bill_list { get; set; } /// <summary> /// 收款類型 /// </summary> public string payment_type { get; set; } /// <summary> /// 交易的創建人角色 /// </summary> public string operator_role { get; set; } /// <summary> /// 接口類型 /// </summary> public string service { get; set; } } }
獲取xml數據塞入queryorder類：
private static QueryOrder InsQueryOrder(string requestData) { QueryOrder queryorder = new QueryOrder(); XmlDocument xmldoc = new XmlDocument(); xmldoc.LoadXml(requestData); //獲取節點列表 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; } }
然后可以根據訂單狀態寫自己的業務邏輯了：
if (queryorder.is_success == "T") { if (queryorder.trade_status == "TRADE_SUCCESS") { WriteReturnZFBDetail(queryorder); FilliedOnline(queryorder.out_trade_no); } }
