php - 在哪里可以找到结算协议(protocol) ID 然后在结帐时使用它

Question

大家好，我对在用户批准计费计划后在哪里可以找到计费协议(protocol) ID (BAID) 感到困惑。

使用 REST-API

目前paypal在我执行协议(protocol)后返回这个。

Agreement {#346 ▼
  -_propMap: array:9 [▼
    "id" => "I-N61SE6562BGN"
    "state" => "Active"
    "description" => "This is a subscription fee for using Talent Scout. It will be use to maintain the site and make users secure."
    "payer" => Payer {#349 ▶}
    "plan" => Plan {#350 ▶}
    "links" => array:5 [▶]
    "start_date" => "2019-06-17T07:00:00Z"
    "shipping_address" => Address {#364 ▶}
    "agreement_details" => AgreementDetails {#365 ▶}
  ]
}

我很困惑上面代码中的ID是不是BAID。如果它是我正在寻找的 BAID，那么我想将其插入结帐中，这样用户以后结帐时就不必再次登录。

用户选择和结帐时的代码

$payer = new Payer();
    $payer->setPaymentMethod('paypal');
    $total = 0;
    Session::set('duration', $request['duration']);
    if($request['duration'] == '1'){
        $item_1 = new Item();
        $item_1->setName('1 week duration') // item name
        ->setCurrency('PHP')
        ->setQuantity(1)
        ->setPrice($request['hiddenprice'][0]); // unit price
        $total = $request['hiddenprice'][0];
    }
    elseif($request['duration'] == '2'){
        $item_1 = new Item();
        $item_1->setName('2 weeks duration') // item name
        ->setCurrency('PHP')
        ->setQuantity(1)
        ->setPrice($request['hiddenprice'][1]); // unit price
        $total = $request['hiddenprice'][1];
    }
    elseif ($request['duration'] == '3') {
        $item_1 = new Item();
        $item_1->setName('3 weeks duration') // item name
        ->setCurrency('PHP')
        ->setQuantity(1)
        ->setPrice($request['hiddenprice'][2]); // unit price
        $total = $request['hiddenprice'][2];
    }

    // add item to list
    $item_list = new ItemList();
    $item_list->setItems(array($item_1));
    $amount = new Amount();
    $amount->setCurrency('PHP')
        ->setTotal($total);
    $transaction = new Transaction();
    $transaction->setAmount($amount)
        ->setItemList($item_list)
        ->setDescription('Your transaction description');
    $redirect_urls = new RedirectUrls();
    $redirect_urls->setReturnUrl(\URL::route('payment.status'))
        ->setCancelUrl(\URL::route('payment.status'));
    $payment = new Payment();
    $payment->setIntent('Sale')
        ->setPayer($payer)
        ->setRedirectUrls($redirect_urls)
        ->setTransactions(array($transaction));
    try {
        $payment->create($this->_api_context);
    } catch (\PayPal\Exception\PPConnectionException $ex) {
        if (\Config::get('app.debug')) {
            echo "Exception: " . $ex->getMessage() . PHP_EOL;
            $err_data = json_decode($ex->getData(), true);
            exit;
        } else {
            die('Some error occur, sorry for inconvenient');
        }
    }
    foreach($payment->getLinks() as $link) {
        if($link->getRel() == 'approval_url') {
            $redirect_url = $link->getHref();
            break;
        }
    }
    // add payment ID to session
    Session::put('paypal_payment_id', $payment->getId());
    if(isset($redirect_url)) {
        // redirect to paypal
        return Redirect::away($redirect_url);
    }
    Session::flash('failed', 'Something went wrong!');
    return Redirect::to('/home')
        ->with('error', 'Unknown error occurred');
    }

是的，执行协议(protocol)后返回对象中的ID就是计费协议(protocol)ID，以后可以用它来查询协议(protocol)的信息。
