公眾號搭建淘寶、京東、拼多多查券平臺
阿新 • • 發佈：2018-11-14
雙十一之前終於把淘寶客公眾號搭建好了，雖然耗時不少，但還是蠻有成就感的，能不能賺錢就另外一回事了。
我這裡用到了淘寶聯盟api許可權、拼多多平臺介面api、京東申請比較麻煩就沒有申請，所以京東使用了第三方免費介面，各聯盟賬號api許可權申請我就不贅述了，有疑問的話可以在下面留言，或加我微信公眾號“網購有券”聯絡我。
淘寶找券實現
原理：
- 通過使用者手淘分享的商品資訊，資訊中包含商品關鍵字和連結，使用商品關鍵字通過淘寶 通用物料搜尋API 介面查詢一批商品；
- 然後通過分享資訊中的淘寶連結http抓包方式獲取淘寶商品item id;
- 然後通過item id在查詢的一批商品中找到指定的商品優惠券、佣金等資訊。
public static string GetTaobaoCoupon(RequestMessageText responseMessageText) { string itemInfo = responseMessageText.Content.Trim(); string responeMessage = ""; try { Match m_title = Regex.Match(itemInfo, @"【.*】"); string temp = m_title.Value; if (!string.IsNullOrEmpty(temp)) { temp = temp.Substring(1, temp.Length - 2); } else { return ""; } if (temp.Contains("#手聚App")) { int IndexofA = temp.IndexOf("寶貝不錯:"); int IndexofB = temp.IndexOf("(分享自"); temp = temp.Substring(IndexofA + 5, IndexofB - IndexofA - 5); } string title = temp; //通過商品關鍵字查詢商品 ITopClient client = new DefaultTopClient(taobaoApiUrl,taobaoAppkey, taobaoSecret); TbkDgMaterialOptionalRequest req = new TbkDgMaterialOptionalRequest();

京東、拼多多找券
京東、拼多多找券都比較簡單，微信支援京東、拼多多連結，可以通過連結獲取到商品id，然後直接通過介面使用商品id找券。
京東程式碼：使用了第三方介面（好京客）
public static string GetJDCoupon(RequestMessageText requestMessageText) { string msg = requestMessageText.Content; Match m_goods = Regex.Match(msg, @"(?<=product\/)([0-9]*)|(?<=sku=)([0-9]*)"); string skuId = m_goods.Value; if (string.IsNullOrEmpty(skuId)) { // LogHelper.WriteLog(typeof(WechatController), "獲取京東skuid失敗" + msg); return ""; } try { var hjkGoodsDetail = hjkApi.GetJDGoodsDetail(skuId); if (hjkGoodsDetail.StatusCode == 200 && hjkGoodsDetail.Data != null && !string.IsNullOrEmpty(hjkGoodsDetail.Data.CouponList)) { var model = hjkApi.GetUnionUrl(skuId, hjkGoodsDetail.Data.CouponList); if (model != null && model.StatusCode == 200 && !string.IsNullOrEmpty(model.Data)) { return $"{hjkGoodsDetail.Data.SkuName}\n【在售價】{hjkGoodsDetail.Data.WlPrice}元\n【巻後價】{hjkGoodsDetail.Data.WlPriceAfter} 元\n\n\ue231 <a href='{model.Data}'>點選這裡領券下單</a>\n\n"; } else { return ConfigurationManager.AppSettings["jd_nocoupon_msg"].Replace("\\n", "\n").Replace("\\ue231", "\ue231"); } } else { return ConfigurationManager.AppSettings["jd_nocoupon_msg"].Replace("\\n", "\n").Replace("\\ue231", "\ue231"); } } catch (Exception ex) { //LogHelper.WriteLog(typeof(WechatController), "獲取京東skuid失敗" + ex.Message); return ""; } }
拼多多程式碼如下：

PddCommonApi.AccessToken = "";
string msg = responseMessageText.Content;
Match m_goods = Regex.Match(msg, @"(?<=goods_id=)([0-9]*)");
string goods_id = m_goods.Value;
if (string.IsNullOrEmpty(goods_id))
{
//LogHelper.WriteLog(typeof(WechatController), "獲取拼多多goods id失敗" + msg);
return "";
}
DdkApi api = new DdkApi();
var model = new DetailDdkGoodsRequestModel()

catch (Exception ex)

return "";
}
