PHP如何获取Amazon API JSON数组的特定部分

Question

我使用Amazon产品广告API在JSON数组中检索我网站上的产品信息。

在调用该接口时，我得到的示例结果如下所示，这是使用print_r($response)时的结果。

{"ItemsResult":{"Items":[{"ASIN":"B010FTYIUS","DetailPageURL":"https://www.amazon.com/dp/B010FTYIUS?tag=hangarflights-20&linkCode=ogi&th=1&psc=1","Offers":{"Listings":[{"Id":"DAjnW3%2BLO70EsyLN%2FMQLwyvR8afWckVN8fvJ6mojtJQMdPh0yCEgxtv3gBjPMOwUQp8RvEP56ao%2FWFAtjhHkFRQRsYs27pFtiLuL9DiaqdIprrqGBw03IQ%3D%3D","Price":{"Amount":1095.95,"Currency":"USD","DisplayAmount":"$1,095.95"},"ViolatesMAP":false}]}}]}}

例如，我如何才能获得价格金额(这里是1095.95)？我已经尝试了多种方法，比如echo $response["ItemsResult"]["items"]["Offers"]["Listings"]["Price"]["Amount"]，但都没有成功。

Answer 1

$response = '{"ItemsResult":{"Items":[{"ASIN":"B010FTYIUS","DetailPageURL":"https://www.amazon.com/dp/B010FTYIUS?tag=hangarflights-20&linkCode=ogi&th=1&psc=1","Offers":{"Listings":[{"Id":"DAjnW3%2BLO70EsyLN%2FMQLwyvR8afWckVN8fvJ6mojtJQMdPh0yCEgxtv3gBjPMOwUQp8RvEP56ao%2FWFAtjhHkFRQRsYs27pFtiLuL9DiaqdIprrqGBw03IQ%3D%3D","Price":{"Amount":1095.95,"Currency":"USD","DisplayAmount":"$1,095.95"},"ViolatesMAP":false}]}}]}}';
$response = json_decode($response, true);



echo $response["ItemsResult"]["Items"][0]['Offers']["Listings"][0]["Price"]["Amount"]; //1095.95
