解析 onessignal API 响应

Question

我想用PHP解析来自onesignal API的响应。以下是API响应的结构。我想只打印某些参数。我怎样才能做到这一点？

    }
}

我使用了他们给出的PHP代码，但是没有成功。

 $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "https://onesignal.com/api/v1/notifications/c3971bca-b49f- 47c8-b9a0-ace613a06431?app_id=MYAPPID");
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json',
                           'Authorization: Basic AUTHKEY'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_HEADER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

    $response = curl_exec($ch);
    curl_close($ch);
        $return["allresponses"] = $response;
    $return = json_encode( $return);

      print("\n\nJSON received:\n");


      $yummy = json_decode($return, true);
      print_r($yummy);
      echo("<br>");
      echo "checking---".$yummy[0]['app_id']; // I donnot know to to access this
      print("\n");

我想只打印某些参数，以便做进一步处理。但是我无法解析响应。

你的JSON是一个对象，而不是一个数组，所以（一旦你对它进行了解码）你可以直接访问它的属性。只要去掉 [0] 就没有问题了。

echo "checking---".$yummy['app_id'];

演示。https:/3v4l.orgQKUQN。.

该 [0] 如果JSON是一个数组，并且你的数据在这个数组的第一个元素里面，那么这个方法就有意义了。但是对于一个简单的对象来说，没有额外的层级这样的东西可以穿越。
