Laravel Paypal 付款。怎样才能让它完整呢？它返回 json 响应

Question

我已经使用他们的文档创建了单批付款。这样我就可以汇款给卖家。但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？这是我在控制器功能中的代码 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('[e-mail]')            ->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 付款页面，用户将在该页面登录并支付金额，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，但我找不到示例/解决方案。

Answer 1

付款用于将资金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 调用者，系统会自动批准来自您帐户的付款。

Answer 2

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

需要两个函数。

1 创建付款对象 2 使用 API 从 paypal 获取付款详细信息，然后执行此付款，以便将金额转入收款账户。

以下需要 3 条路线

1. 创建支付对象

2. 获取详细付款对象详细信息（查看客户是否已使用 paypal 结账支付金额）并执行付款以汇款（这是成功 url）

3. 取消网址（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');
