ios - 为什么我得不到 eBay 响应的产品价格？

Question

我通过这种方式获取 ebay 产品信息:

http://open.api.ebay.com/shopping?
   callname=FindProducts&
   responseencoding=XML&
   appid=YourAppIDHere&
   siteid=0&
   version=525&
   QueryKeywords=harry%20potter&
   AvailableItemsOnly=true&
   MaxEntries=2

但我没有得到产品价格作为回应。我应该更改请求参数吗？还是我应该使用另一种 ebay 网络服务方法来获取此信息？

响应是

检查 this Link : Getting Item Descriptions and Item Specifics http://developer.ebay.com/DevZone/shopping/docs/CallRef/GetSingleItem.html#sampledescriptionitemspecifics

URL 格式(HTTP GET)。另请参阅此 URL 的非包装版本。对于 XML 以外格式的结果，为 responseencoding 指定一个不同的值。

http://open.api.ebay.com/shopping?
   callname=GetSingleItem&
   responseencoding=XML&
   appid=YourAppIDHere&
   siteid=0&
   version=515&
   ItemID=180126682091&
   IncludeSelector=Description,ItemSpecifics

您必须传递 ItemID 才能获得 Detailed Description .
