公众号搭建淘宝、京东、拼多多查券平台
双十一之前终于把淘宝客公众号搭建好了，虽然耗时不少，但还是蛮有成就感的，能不能赚钱就另外一回事了。
我这里用到了淘宝联盟api权限、拼多多平台接口api、京东申请比较麻烦就没有申请，所以京东使用了第三方免费接口，各联盟账号api权限申请我就不赘述了。
效果：
淘宝找券实现
原理：
- 通过用户手淘分享的商品信息，信息中包含商品关键字和链接，使用商品关键字通过淘宝 通用物料搜索API 接口查询一批商品；
- 然后通过分享信息中的淘宝链接http抓包方式获取淘宝商品item id;
- 然后通过item id在查询的一批商品中找到指定的商品优惠券、佣金等信息。
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("宝贝不错:");
int IndexofB = temp.IndexOf("(分享自");
temp = temp.Substring(IndexofA + 5, IndexofB - IndexofA - 5);
}
string title = temp;
//通过商品关键字查询商品

京东、拼多多找券
京东、拼多多找券都比较简单，微信支持京东、拼多多链接，可以通过链接获取到商品id，然后直接通过接口使用商品id找券。
京东代码：使用了第三方接口（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), "获取京东skuid失败" + 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【在售价】{hjkGoodsDetail.Data.WlPrice}元\n【巻后价】{hjkGoodsDetail.Data.WlPriceAfter} 元\n\n\ue231 <a href='{model.Data}'>点击这里领券下单</a>\n\n";
