Paypal PHP REST服务-“访问令牌没有必需的作用域”

Question

我正在使用Paypal REST SDK编写PHP代码。我已经设置了我的沙箱帐户使用澳元。当我意识到我最初的交易是以美元进行的，并且交易被冻结后，我就做出了这个决定。

使用我修改过的代码，我正在尝试创建支付--我假设我会得到一个URL，它将允许我重定向用户批准支付。

    //### FundingInstrument
    // A resource representing a Payer's funding instrument.
    // For direct credit card payments, set the CreditCard
    // field on this object.
    $fi = new FundingInstrument();
    $creditCardToken = new CreditCardToken();
    $creditCardToken->setCreditCardId($creditcard->cardToken);
    $fi->setCreditCardToken($creditCardToken);

    // ### Payer
    // A resource representing a Payer that funds a payment
    // For direct credit card payments, set payment method
    // to 'credit_card' and add an array of funding instruments.
    $payer = new Payer();
    $payer->setPaymentMethod("credit_card")
        ->setFundingInstruments(array($fi));

    // ### Itemized information
    // (Optional) Lets you specify item wise
    // information
    $paymentItems=Yii::app()->session['paymentitems'];
    $items=array();
    $total=0;
    foreach ($paymentItems as $item)
    {
        $pp_item = new Item();
        $pp_item->setName("Donation to ".$item->organisation->organisationName)
            ->setCurrency('AUD')
            ->setQuantity(1)
            ->setPrice($item->amount);
        array_push($items,$pp_item);
        $total+=(float)$item->amount;
    }
    $itemList = new ItemList();
    $itemList->setItems($items);        
    // ### Amount
    // Lets you specify a payment amount.
    // You can also specify additional details
    // such as shipping, tax.
    $amount = new Amount();
    $amount->setCurrency("AUD")
        ->setTotal($total);

    // ### Transaction
    // A transaction defines the contract of a
    // payment - what is the payment for and who
    // is fulfilling it. 
    $transaction = new Transaction();
    $transaction->setAmount($amount)
        ->setItemList($itemList)
        ->setDescription("Payment description");

    // ### Payment
    // A Payment Resource; create one using
    // the above types and intent set to sale 'sale'
    $payment = new Payment();
    $payment->setIntent("sale")
        ->setPayer($payer)
        ->setTransactions(array($transaction));
    // ### Create Payment
    // Create a payment by calling the payment->create() method
    // with a valid ApiContext (See bootstrap.php for more on `ApiContext`) href

    // The return object contains the state.
    try {
        $response=$payment->create($apiContext);
        var_dump($response);
        //$this->redirect($response->links[0]->href);
    } catch (PayPal\Exception\PPConnectionException $ex) {
        echo "Exception: " . $ex->getMessage() . PHP_EOL;
        var_dump($ex->getData());
        exit(1);
    }

任何关于这条信息的想法。在澳大利亚，Paypal似乎不支持直接信用卡支付，但我不认为这是问题所在。

在您的Paypal developer帐户的“我的应用程序”下，确保在“应用程序设置”部分启用了您尝试使用的功能。
