This update to allow you to change the shipping address in the paypal express checkout

[butta74]

I ask if it is possible to make this change.

File \vendor\omnipay\paypal\src\Message\RestAuthorizeRequest.php Line 254 ADD:

    $shipping_address = $this->getShippingAddress();
    if ($shipping_address) {
        $data['transactions'][0]['item_list']["shipping_address"] = $shipping_address;
    }

File \vendor\omnipay\common\src\Common\Message\AbstractRequest.php -- Line 541 ADD:

/**
 * Custom Shipping Address
 */
public function getShippingAddress()
{
    return $this->getParameter('shipping_address');
}

/**
 * Set Shipping Address
 * @return $this
 */
public function setShippingAddress($value)
{
    return $this->setParameter('shipping_address', $value);
}

So in my controller I can call "purchase" method with custom shipping_addres :

$response = $this->gateway->purchase([
'transactionId' => $myIdTransaction
'amount' => $tot_payment,
'currency' => $currency,
'returnUrl' => $myurl,
'cancelUrl' => $myCancelUrl,
'shipping_address' => [
"line1"=> "111 First Street",
"city"=> "Saratoga",
"country_code"=> "US",
"postal_code"=> "95070",
"state"=> "CA"
]
])->send();

It's work for me.
Thanks
