我正在使用PayPal rest API，但我无法让它工作。
我已经复制了他们为创建付款提供的代码。 当我运行它并回显响应时，响应似乎还可以。 科德是 ：
<?php
// 1. Autoload the SDK Package. This will include all the files and classes to your autoloader
require __DIR__ . '/PayPal-PHP-SDK/autoload.php';
use PayPalApiAmount;
use PayPalApiDetails;
use PayPalApiItem;
use PayPalApiItemList;
use PayPalApiPayer;
use PayPalApiPayment;
use PayPalApiRedirectUrls;
use PayPalApiTransaction;
// 2. Provide your Secret Key. Replace the given one with your app clientId, and Secret
// h**ps://developer.paypal.com/webapps/developer/applications/myapps
$apiContext = new PayPalRestApiContext(
new PayPalAuthOAuthTokenCredential(
'ClientID IS HERE AND IS CORRECT', // ClientID
'Secret IS HERE AND IS CORRECT' // ClientSecret
)
);
// 3. Lets try to create a Payment
// h**ps://developer.paypal.com/docs/api/payments/#payment_create
$payer = new PayPalApiPayer();
$payer->setPaymentMethod('paypal');
/*$amount = new PayPalApiAmount();
$amount->setTotal('1.00');
$amount->setCurrency('USD');*/
$item1 = new Item();
$item1->setName('Ground Coffee 40 oz')
->setCurrency('USD')
->setQuantity(1)
->setPrice(7.5);
$item2 = new Item();
$item2->setName('Granola bars')
->setCurrency('USD')
->setQuantity(5)
->setPrice(2);
$itemList = new ItemList();
$itemList->setItems(array($item1, $item2));
//Additional payment details
//Use this optional field to set additional payment information such as tax, shipping charges etc.
$details = new Details();
$details->setShipping(1.2)
->setTax(1.3)
->setSubtotal(17.50);
//Amount
//Lets you specify a payment amount. You can also specify additional details such as shipping, tax.
$amount = new Amount();
$amount->setCurrency("USD")
->setTotal(20)
->setDetails($details);
$transaction = new PayPalApiTransaction();
$transaction->setAmount($amount);
$redirectUrls = new PayPalApiRedirectUrls();
$redirectUrls->setReturnUrl("h**ps://example.com/your_redirect_url.html")
->setCancelUrl("h**ps://example.com/your_cancel_url.html");
$payment = new PayPalApiPayment();
$payment->setIntent('sale')
->setPayer($payer)
->setTransactions(array($transaction))
->setRedirectUrls($redirectUrls);
// 4. Make a Create Call and print the values
try {
$payment->create($apiContext);
// echo "nnRedirect user to approval_url: " . $payment->getApprovalLink() . "n";
}
catch (PayPalExceptionPayPalConnectionException $ex) {
// This will print the detailed information on the exception.
//REALLY HELPFUL FOR DEBUGGING
echo $ex->getData();
}
return($payment);
?>
我认为这行得通
接下来，我使用他们的示例代码创建了按钮脚本：
<!DOCTYPE html>
<head>
<meta h**p-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1">
<script src="h**ps://www.paypalobjects.com/api/checkout.js"></script>
</head>
<body>
<div id="paypal-button-container"></div>
<script>
paypal.Button.render({
env: 'sandbox', // sandbox | production
commit: true,
payment: function() {
// Set up a url on your server to create the payment
var CREATE_URL = 'h**ps://MySite.com/PayPalRest/first.php';
// Make a call to your server to set up the payment
console.log(paypal.request.post(CREATE_URL));
return paypal.request.post(CREATE_URL)
.then(function(res) {
return res.paymentID;
});
},
// onAuthorize() is called when the buyer approves the payment
onAuthorize: function(data, actions) {
// Set up a url on your server to execute the payment
var EXECUTE_URL = '/demo/checkout/api/paypal/payment/execute/';
// Set up the data you need to pass to your server
var data = {
paymentID: data.paymentID,
payerID: data.payerID
};
// Make a call to your server to execute the payment
return paypal.request.post(EXECUTE_URL, data)
.then(function (res) {
window.alert('Payment Complete!');
});
}
}, '#paypal-button-container');
</script>
</body>
当我运行(单击按钮(时，灯箱弹出几秒钟，然后消失。 该人没有机会验证其帐户并付款。
我已经通读了所有 sdk，可以让他们的样本正常工作。 我认为返回的付款代码一定是错误的或其他什么 - 任何如何调试的帮助建议都很棒。
对不起，长帖子。
问题可能出在多个地方。
你能先检查浏览器开发者日志，看看是否有任何错误吗？
如果您收到类似 - 无法加载 https://www.paypal.com/webapps/hermes/api/logger：对预检请求的响应未通过访问控制检查："访问控制允许源"标头包含无效值"null//null"。因此，不允许访问源"空"。
然后尝试运行服务器的页面，看看是否有帮助？
