PayPal 快速结帐 + php cURL 执行付款，不在沙盒上显示付款通知

Question

我正在测试PayPal集成，在我的 Apache 服务器上使用 vhost -> test.it/paypal 进行 PHP 演示测试。 我使用Express Checkout + Server-side REST (cURL)。 我的js添加PayPal按钮是：

<script>
var CREATE_PAYMENT_URL  = 'http://test.it/paypal/create-payment.php';
var EXECUTE_PAYMENT_URL = 'http://test.it/paypal/execute-payment.php';
paypal.Button.render({
env: 'sandbox', // Or 'production',
commit: true, // Show a 'Pay Now' button
locale: 'it_IT',
style: {
size: 'small',
color: 'blue',
shape: 'pill',
label: 'checkout'
},
commit: true, // Show a 'Pay Now' button
payment: function() {
// Make a call to the merchant server to set up the payment
return paypal.request.post(CREATE_PAYMENT_URL).then(function(res) {
//return res.payToken;
console.log(res);
return res.paymentID;
});
},
// Wait for the payment to be authorized by the customer
onAuthorize: function(data) {
//alert(data.payerID);
return paypal.request.post(EXECUTE_PAYMENT_URL, {
paymentID: data.paymentID,
payerID:   data.payerID
}).then(function(res) {
/* Go to a success page */
console.log('SUCCESS!!!!!!!!!');
console.log(res);
// The payment is complete!
// You can now show a confirmation message to the customer
alert('pagamento completato');
}).catch(function (err) {
/* Go to an error page  */
console.log('ERROR!!!!!!!!!');
console.log(data);
console.log(err);
});
}
}, '#paypal-button');
</script>

创建付款.php如下：

<?php
session_start();
include 'config.php';
// autenticazione per ottenere user token
$url_wbs="https://api.sandbox.paypal.com/v1/oauth2/token";
$ch = curl_init();
$clientId = "Aeet9T-pG4XQU-GnDL2uSrkJQ4_qaxgAu9XtVTP6qeuXDGBOnHf2TiVF2Qv5OurFmSo9dPkwVk-x0J3x";
$secret = "EGQguUgHcN4TLjAEAXb4Jo8qoTQCvC3o_54FL2r2wQUtjbGoRoWeRlDyNNhU3HO8lpdexzNsW-ePb2qe";
// id web experience profile
$experience_profile_id="XP-V52K-SKNH-FK7Y-HLYQ";
curl_setopt($ch, CURLOPT_URL, $url_wbs);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, $clientId.":".$secret);
curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");
$result = curl_exec($ch);
curl_close($ch);
if(empty($result))die("Error: No response.");
else
{
$obj=json_decode( $result );
//var_dump($obj->access_token);
$_SESSION['token']=$obj->access_token;
// imposto il web profile ottenendone l'id
$header_rest_call[]='Authorization: Bearer '.$obj->access_token;
$json_body='{
"intent": "sale",
"experience_profile_id":"'.$experience_profile_id.'",
"redirect_urls":
{
"return_url": "http://test.it/paypal/checkout.php",
"cancel_url": "http://test.it/paypal/pagamento-cancellato.php"
},
"payer":
{
"payment_method": "paypal"
},
"transactions": [
{
"amount":
{
"total": "4.00",
"currency": "EUR",
"details":
{
"subtotal": "2.00",
"shipping": "1.00",
"tax": "2.00",
"shipping_discount": "-1.00"
}
},
"item_list":
{
"items": [
{
"quantity": "1",
"name": "item 1",
"price": "1",
"currency": "EUR",
"description": "item 1 description",
"tax": "1"
},
{
"quantity": "1",
"name": "item 2",
"price": "1",
"currency": "EUR",
"description": "item 2 description",
"tax": "1"
}]
},
"description": "The payment transaction description.",
"invoice_number": "merchant invoice",
"custom": "merchant custom data"
}]
}';
$obj_payment=get_obj_json($payment_creation_url,$header_rest_call,$json_body,'POST');
//var_dump($obj_payment->id);
$response=array(
'paymentID'=>$obj_payment->id
);
echo json_encode($response);
}
?>

执行付款.php如下：

<?php
session_start();
include 'config.php';
// imposto il web profile ottenendone l'id
$header_rest_call[]='Authorization: Bearer '.$_SESSION['token'];
// indirizzo wbs per pagamento
$url_payment="https://api.sandbox.paypal.com/v1/payments/payment/".$_POST['paymentID']."/execute/";
$json_body='{
"payer_id": "'.$_POST['payerID'].'";
}';
$obj_payment=get_obj_json($url_payment,$header_rest_call,$json_body,'POST');
echo json_encode($obj_payment);
?>

当我单击PayPal按钮时，PayPal登录表单会正确显示购买数据，我输入凭据，最后单击"立即付款" 按钮。看来付款成功了。.但在沙盒帐户中 ->活动 -> 没有过渡/付款的痕迹..？

Answer 1

问题出在付款/执行请求的格式错误的 json 中。

$json_body='{
"payer_id": "'.$_POST['payerID'].'";

}';

在 -> $_POST['payerID'] 之后，我错误地输入了一个分号。

现在它工作了！
