如何更改此Amazon Product Advertising API PHP连接以搜索ISBN
如何更改此Amazon Product Advertising API PHP连接以搜索ISBN
提问于 2016-01-12 23:35:44
我正在使用PHP类与Amazon Product advertising进行交互。我需要能够查找书籍(ISBN编号)，但是这个类似乎不支持它。我试图修改关键字函数以接受ISBN编号，但我没有运气。有没有人能给我指出正确的资源方向，以学习如何做到这一点，或者如果这是一个简单的修复程序，向我展示它？提前谢谢你

Lookup by ISBN要求将IdType参数设置为ISBN。扩展您的代码可能如下所示：
public function getItemByISBN($isbn)
{
$parameters = array("Operation" => "ItemLookup",
"ItemId" => $isbn,
"IdType" => "ISBN"
"ResponseGroup" => "Medium");
$xml_response = $this->queryAmazon($parameters);
return $this->verifyXmlResponse($xml_response);
