检索客户来源时的条带响应

Question

I am trying to retrieve all cards for a particular customer, by supplying a customer ID. Per the documentation, I am expecting the following response:

Stripe\Collection JSON: {
  "object" => "list",
  "url" => "/v1/customers/cu_16jdAj2eZvKYlo2CbrCP4HRs/sources",
  "has_more" => false,
  "data" => [
    [0] => Stripe\Card JSON: {
      "id": "card_14bIFkou9GUI42eZvKYlo2Cs",
      "object": "card",
      "last4": "4242",
      "brand": "Visa",
      "funding": "credit",
      "exp_month": 11,
      "exp_year": 2018,
      "country": "US",
      "name": "[e-mail]",
      "address_line1": null,
      "address_line2": null,
      "address_city": null,
      "address_state": null,
      "address_zip": null,
      "address_country": null,
      "cvc_check": null,
      "address_line1_check": null,
      "address_zip_check": null,
      "tokenization_method": null,
      "dynamic_last4": null,
      "metadata": {
      },
      "customer": "cus_6Nb0wxYHigk2mX"
    }
    [1] => <Stripe\Card[...] ...>
    [2] => <Stripe\Card[...] ...>
  ]
}

And here's the request I'm making to Stripe. Trying to pull data (ie, an array of all cards) from the $card_list:

\Stripe\Stripe::setApiKey($this->stripe_sk);
$card_list = \Stripe\Customer::retrieve($customer_id)->sources->all(array(
    'object' => 'card'
));

// Return a list of all cards.
$card_list = $card_list->data;
return $card_list;

I would like to know why the Stripe response from $card_list contains additional/unexpected data. Here's what I'm actually getting back:

array(1) {
  [0]=>
  object(Stripe\Card)#292 (5) {
    ["_opts":protected]=>

        }
        ["_retrieveOptions":protected]=>
        array(0) {
        }
      }
      ["customer"]=>
      string(18) "cus_6xCtshHPQiYSdI"
    }
    ["_unsavedValues":protected]=>
    object(Stripe\Util\Set)#270 (1) {
      ["_elts":"Stripe\Util\Set":private]=>
      array(0) {
      }
    }
    ["_transientValues":protected]=>
    object(Stripe\Util\Set)#120 (1) {
      ["_elts":"Stripe\Util\Set":private]=>
      array(0) {
      }
    }
    ["_retrieveOptions":protected]=>
    array(0) {
    }
  }
}

Hoping that someone can explain the "extended" version of the response, that I'm getting here. Thanks in advance!

Answer 1

I stuck in this problem a couple of days ago and I've managed to solve it using json_encode() API like this (need to export this as a AJAX return on my side).

$cards = \Stripe\Customer::retrieve($_SESSION['stripe_customer_id'])->sources->all(array("object" => "card"));
$list = json_encode($cards->data);
echo($list);

Hope this helps.

BTW : Your response looks alike a var_dump() output.
