我试过像普通数组和 JSON 对象一样提取 ASIN。帮忙？

这里是我用来生成上面代码的代码：

       try
   {
   $amazonEcs = new AmazonECS(AWS_API_KEY, AWS_API_SECRET_KEY, 'it', AWS_ASSOCIATE_TAG);

   $amazonEcs->associateTag(AWS_ASSOCIATE_TAG);

   $response = $amazonEcs->category('DVD')->search("Bud Spencer");

   $result=var_dump($response);

  }
  catch
  ...

这似乎不是 json 消息。它似乎是使用 PHP 打印出来的 json 消息。您将使用哪种语言提取信息？

<?php
   $json = '{"a":1,"b":2,"c":3}';

   //an object of type stdClass
   $result = json_decode($json);
   echo $result->a, "\r\n";
   echo $result->b, "\r\n";
   echo $result->c, "\r\n";

   //an associative array
   $result = json_decode($json, true);
   echo $result['a'], "\r\n";
   echo $result['b'], "\r\n";
   echo $result['c'], "\r\n";
?>
