如何使用php访问Amazon api中超过10个项目的详细信息？

Question

我正在使用amazon api并使用来自在线资源的代码http://www.codediesel.com/php/accessing-amazon-product-advertising-api-in-php/.

当我使用amazon api进行搜索查询时,我想获得超过10个产品的详细信息.我知道每次调用获得10个数据的amazon api策略,但是可以通过创建循环或其他东西获得更多数据吗？

当我提出请求时,我已经分配了以下参数

 $parameters = array("Operation"     => "ItemSearch",
                     "SearchIndex"   => "Electronics",
                     "ResponseGroup" => "Images,ItemAttributes,EditorialReview,Offers ",  
                     "ItemPage"=>"10",
                     "Keywords" => $search                                                                                                                                              );

因此,即使我要求10页的结果,我不确定如何显示每个页面(1到10)的数据,所以总共我得到100个项目,当我进行查询.当我尝试运行代码时,我得到以下响应:

SimpleXMLElement Object ( 
    [Request] => SimpleXMLElement Object ( 
        [IsValid] => True            
        [ItemSearchRequest] => SimpleXMLElement Object ( 
            [ItemPage] => 10 
            [Keywords] => laptop 
            [ResponseGroup] => Array ( 
                [0] => Images 
                [1] => ItemAttributes 
                [2] => EditorialReview 
                [3] => Offers 
            ) 
            [SearchIndex] => Electronics 
        ) 
    ) 
    [TotalResults] => 3383691 
    [TotalPages] => 338370 
    [MoreSearchResultsUrl] => http://www.amazon.co.uk/gp/redirect.html?camp=2025&creative=12734&location=http%3A%2F%2Fwww.amazon.co.uk%2Fgp%2Fsearch%3Fkeywords%3Dlaptop%26url%3Dsearch-.................(and on)
)

是的，您需要循环 10 次并附加一个数组或对象。AWS 文档称这ItemPage实际上是结果页面，因此您只需翻阅 10 次即可获得 100 个结果。

AWS 文档ItemPage：

http://docs.aws.amazon.com/AWSECommerceService/latest/DG/PagingThroughResults.html

$obj = new AmazonProductAPI();

$results = array();

for ($i=1;$i<=10;$i++) {
    $parameters = array("Operation"     => "ItemSearch",
                 "SearchIndex"   => "Electronics",
                 "ResponseGroup" => "Images,ItemAttributes,EditorialReview,Offers ",  
                 "ItemPage"=>$i,
                 "Keywords" => $search);

    $results[] = $obj->searchProducts($parameters);

}

foreach ($results as $r) {
    //do your stuff
}
