我已經(jīng)使用他們的文檔創(chuàng)建了單批付款。這樣我就可以匯款給賣家。但我不知道之后我應(yīng)該做什么。如何顯示付款表格，用戶可以在其中登錄 PayPal 并支付金額？這是我在控制器功能中的代碼?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;}當(dāng)我點(diǎn)擊路由訪問(wèn)此代碼時(shí)，我收到此 json 響應(yīng)。{ "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" } ] }我希望用戶將被帶到 PayPal 付款頁(yè)面，用戶將在該頁(yè)面登錄并支付金額，然后 PayPal 會(huì)通知我有關(guān)付款的信息。但我試圖通過(guò)互聯(lián)網(wǎng)找到解決方案，但我找不到示例/解決方案。

付款用于將資金從您的帳戶發(fā)送到另一個(gè)帳戶。沒有可顯示或登錄的表格。您是 API 調(diào)用者，系統(tǒng)會(huì)自動(dòng)批準(zhǔn)來(lái)自您帳戶的付款。

解決方案是創(chuàng)建一個(gè)付款對(duì)象并在其中添加收款人（將作為賣家接收付款）電子郵件地址。
需要兩個(gè)函數(shù)。
1 創(chuàng)建付款對(duì)象 2 使用 API 從 paypal 獲取付款詳細(xì)信息，然后執(zhí)行此付款，以便將金額轉(zhuǎn)入收款賬戶。
以下需要 3 條路線
創(chuàng)建支付對(duì)象
獲取詳細(xì)付款對(duì)象詳細(xì)信息（查看客戶是否已使用 paypal 結(jié)賬支付金額）并執(zhí)行付款以匯款（這是成功 url）
取消網(wǎng)址（當(dāng)客戶取消付款時(shí)）。它將客戶重定向回平臺(tái)（網(wǎng)站）
這是完整的代碼示例
路線
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');
