Laravel 贝宝付款。如何使它完整？它returnsjson响应

Question

我已经使用他们的 documentation 创建了单批付款。以便我可以汇款给卖家。

但是我不知道之后我应该做什么。如何显示付款表格，用户可以在其中登录 PayPal 并支付金额？

这是我在控制器函数中的代码

 public function payViaPaypal(){
   
        $payouts = new \PayPal\Api\Payout();
        $senderBatchHeader = new \PayPal\Api\PayoutSenderBatchHeader();
        $senderBatchHeader->setSenderBatchId(uniqid('invoice-1qaqw23wdwdwew').microtime('true'))
            ->setEmailSubject("You have a Payout!");

        $senderItem = new \PayPal\Api\PayoutItem();
        $senderItem->setRecipientType('Email')
            ->setNote('Thanks for your patronage!')
            ->setReceiver('sb-cwdzv2614448@business.example.com')
            ->setSenderItemId(uniqid().microtime('true'))
            ->setAmount(new \PayPal\Api\Currency('{
                        "value":"1.0",
                        "currency":"USD"
                    }'));

        $payouts->setSenderBatchHeader($senderBatchHeader)
            ->addItem($senderItem);



        $request = clone $payouts;
        $redirect_url = null;
        try {
            $output = $payouts->create(null, $this->api_context);

        } catch (\Exception $e) {
            dd('here',$this->errorDetails($e));
        }
//        dd("Created Single Synchronous Payout", "Payout", $output->getBatchHeader()->getPayoutBatchId(), $request, $output);
        $redirect_url = null;
        foreach($output->getLinks() as $link) {
            if($link->getRel() == 'self') {
                $redirect_url = $link->getHref();
                break;
            }
        }
        return $output;
}

当我点击路由访问此代码时，我收到此 json 响应。

{ "batch_header": { "payout_batch_id": "79CTFV2X5TS58", "batch_status": "PENDING", "sender_batch_header": { "sender_batch_id": "invoice-1qaqw23wdwdwew5f0f5003612091594839043.3978", "email_subject": "You have a Payout!" } }, "links": [ { "href": "https://api.sandbox.paypal.com/v1/payments/payouts/79CTFV2X5TS58", "rel": "self", "method": "GET", "enctype": "application/json" } ] }

我希望用户将被带到 PayPal 支付页面，用户将在该页面上登录并支付金额，然后 PayPal 会通知我有关付款的信息。

但我试图通过互联网找到解决方案，但没有 example/solution 我能找到。

Answer 1

付款用于将钱从您的帐户发送到另一个帐户。没有可显示或登录的表格。您是 API 来电者，付款会自动批准为来自您的帐户。

如果您想要一个表单供用户批准从他们的帐户向其他帐户付款，请使用发票：https://developer.paypal.com/docs/invoicing/

或者，也许您不需要发票表格，而只需要具有 'payee' 收件人集的常规 PayPal Checkout：https://developer.paypal.com/docs/checkout/integration-features/custom-payee/

Answer 2

我使用了错误的方法。

解决方案是创建一个付款对象并在其中添加收款人（作为卖家接收付款的人）电子邮件地址。

需要两个函数。

1 创建支付对象 2 使用 API 从 paypal 获取付款详情，然后执行此付款，以便可以将金额转入收款账户。

需要3条路线才能跟随

创建支付对象
获取详情支付对象详情（查看客户是否使用paypal结账支付了金额）并执行支付汇款（成功url）
取消url（当客户取消付款时）。它将客户重定向回平台（网站）

这是完整的代码示例

路线

create payment object
Route::get('/invoices/process-payment','Vendor\PayPalController@processPaymentInvoiceViaCheckout');

when payment object is created then get its details and execute payment to send money.
Route::get('/invoices/response-success','Vendor\PayPalController@paypalResponseSuccess');

when cancel to pay 
Route::get('/invoices/response-cancel','Vendor\PayPalController@paypalResponseCancel');
