PayPal API 与 Laravel - 数据更新

我正在尝试实施API of PayPal payment with Laravel 5.1。但是当我登录到PayPal (sandbox)，它使用我在帐户中使用的地址，并且还使用 PayPal 帐户中的名称而不是我网站中的数据。这是我的问题。

我想使用我网站上的数据，因为如果我从我的网站输入送货地址（例如）而不使用它，那就没有意义了。请参阅下面我的代码以供参考（或在下面评论我的一些详细信息）。

class PaypalPaymentController extends BaseController
{

    private $_api_context;

    public function __construct(){
        $paypal_conf = \Config::get('paypal');

        $this->_api_context = new ApiContext(new OAuthTokenCredential(
            $paypal_conf['client_id'],
            $paypal_conf['secret']
        ));

        $this->_api_context->setConfig($paypal_conf['settings']);
    }

    public function payWithPaypal(Request $request){
        $payer = new Payer;
        $payer->setPaymentMethod('paypal');

        $price = 0;

        switch($request->get('amount')) {
            case '10 books':
                $price = 6200;
                break;
            case '20 books':
                $price = 12200;
                break;
            case '50 books':
                $price = 25200;
                break;
            default:
                return redirect()
                        ->route('bookstore.shipping')
                        ->with('danger', 'Please select the right amount of book/s.');
                break;
        }

        $item1 = new Item();
        $item1->setName($request->get('amount'))
                ->setCurrency('PHP')
                ->setQuantity(1)
                ->setPrice($price);

        $item_list = new ItemList();
        $item_list->setItems([$item1]);

        $amount = new Amount();
        $amount->setCurrency('PHP')
                ->setTotal($price);

        $transaction = new Transaction();
        $transaction->setAmount($amount)
                    ->setItemList($item_list)
                    ->setDescription('Books transaction');

        $redirect_urls = new RedirectUrls();
        $redirect_urls->setReturnUrl(route('bookstore.payment-status'))
                        ->setCancelUrl(route('bookstore.payment-status'));

        $payment = new Payment();
        $payment->setIntent('Sale')
                ->setPayer($payer)
                ->setRedirectUrls($redirect_urls)
                ->setTransactions([$transaction]);

         $patchReplace = new Patch();
         $patchReplace->setOp('add')
                    ->setPath('/transactions/0/item_list/shipping_address')
                    ->setValue(json_decode('{
                        "line1": "345 Lark Ave",
                        "city": "Montreal",
                        "state": "QC",
                        "postal_code": "H1A4K2",
                        "country_code": "CA"
                    }'));

         $patchRequest = (new PatchRequest())->setPatches([$patchReplace]);


        try{

            $payment->create($this->_api_context);
            $payment->update($patchRequest, $this->_api_context);

        } catch(\Palpal\Exception\PPConnectionException $e){

            if(\Config::get('app.debug')){
                return redirect()
                        ->route('bookstore.shipping')
                        ->with('danger', 'Connection Timeout.');
            }

            return redirect()
                    ->route('bookstore.shipping')
                    ->with('danger', 'Some error occured, sorry for the inconvenience.');
        }

        foreach($payment->getLinks() as $link){
            if($link->getRel() == 'approval_url'){
                $redirect_url = $link->getHref();
                break;
            }
        }

        Session::put('paypal_payment_id', $payment->getId());

        if(isset($redirect_url)){
            return Redirect::away($redirect_url);
        }

        return redirect()
                ->route('bookstore.shipping')
                ->with('danger', 'Unknown error occured.');
    }

    public function getPaymentStatus(){
        $payment_id = Session::get('paypal_payment_id');
        Session::forget('paypal_payment_id');

        if(empty(Input::get('PayerID')) || empty(Input::get('token'))){
            return redirect()
                    ->route('bookstore.shipping')
                    ->with('danger', 'Payment failed.');
        }

        $payment = Payment::get($payment_id, $this->_api_context);
        $execution = new PaymentExecution();
        $execution->setPayerId(Input::get('PayerID'));

        $result = $payment->execute($execution, $this->_api_context);

        if($result->getState() == 'approved'){
            // Send Email
            $email_data = [
                'number_of_books' => $payment->transactions[0]->item_list->items[0]->name,

                    'country' => $payment->payer->payer_info->shipping_address->country_code,
                ]
            ];

            // Send email function here ...

            return redirect()

}

我还回顾了这个链接 https://stackoverflow.com/questions/39927124/paypal-php-set-no-shipping但它似乎无法回答我的问题。还，what if这个国家有一个省吗？我们怎样才能添加它呢？

Update 1

1. 新增Patch() class.
2. 编辑后的代码在Try Catch.

注：accepted答案也会收到bounty加上up.

更新 2 带教程

1. 对于 PHP/Laravel（我目前使用的是 v5.1），安装这个包贝宝/rest-api-sdk-php https://github.com/paypal/PayPal-PHP-SDK

2. 在 PayPal 中创建沙盒帐户 https://www.sandbox.paypal.com/ph/webapps/mpp/merchant。选择.

3. 继续，直到看到选项，选择购物世界 https://www.paypal.com/ph/webapps/mpp/online-shopping.

4. 登录到开发者.paypal.com https://developer.paypal.com/.

5. Click Accounts https://developer.paypal.com/developer/accounts/. Click 创建账户 https://developer.paypal.com/developer/accounts/create.

6. 选择您想要的国家。在账户类型中选择个人（买家账户）。

7. 添加电子邮件地址，避免使用-. Use _反而。

8. 输入您想要的 PayPal 余额。

9. 单击创建帐户。

让它活起来吗？

https://github.com/paypal/PayPal-PHP-SDK/wiki/Going-Live https://github.com/paypal/PayPal-PHP-SDK/wiki/Going-Live

创建付款后，尝试更新地址，如下所示这个例子 http://paypal.github.io/PayPal-PHP-SDK/sample/doc/payments/UpdatePayment.html.

$paymentId = $createdPayment->getId();

$patch = new \PayPal\Api\Patch();
$patch->setOp('add')
    ->setPath('/transactions/0/item_list/shipping_address')
    ->setValue([
        "recipient_name" => "Gruneberg, Anna",
        "line1" => "52 N Main St",
        "city" => "San Jose",
        "state" => "CA",
        "postal_code" => "95112",
        "country_code" => "US"
    ]);

$patchRequest = new \PayPal\Api\PatchRequest();
$patchRequest->setPatches([$patch]);
$result = $createdPayment->update($patchRequest, $apiContext);

我也查看了此链接，但似乎它无法回答我的问题。另外，如果这个国家有一个省怎么办？我们怎样才能添加它呢？

使用州代码此处列出 https://developer.paypal.com/docs/classic/api/state_codes/.
