PayPal API：对 PHP cURL 的 curl 请求

Question

我正在尝试使用 cURL 在我的网站上添加 PayPal 付款，我找到了如何获取访问令牌，但我不知道如何将此请求（由 PayPal 开发人员提供）转换为 PHP cURL 以继续付款。

curl -v https://api.sandbox.paypal.com/v1/payments/payment \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer <Access-Token>' \
-d '{
  "intent":"sale",
  "redirect_urls":{
    "return_url":"http://example.com/your_redirect_url.html",
    "cancel_url":"http://example.com/your_cancel_url.html"
  },
  "payer":{
    "payment_method":"paypal"
  },
  "transactions":[
    {
      "amount":{
        "total":"7.47",
        "currency":"USD"
      }
    }
  ]
}'

Answer 1

应该是这样的（未测试）：

$ch = curl_init('https://api.sandbox.paypal.com/v1/payments/payment');
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Authorization: Bearer <Access-Token>'
));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$payloadData = '{
  "intent":"sale",
  "redirect_urls":{
    "return_url":"http://example.com/your_redirect_url.html",
    "cancel_url":"http://example.com/your_cancel_url.html"
  },
  "payer":{
    "payment_method":"paypal"
  },
  "transactions":[
    {
      "amount":{
        "total":"7.47",
        "currency":"USD"
      }
    }
  ]
}';

curl_setopt($ch, CURLOPT_POSTFIELDS, $payloadData);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

$result = curl_exec($ch);
$httpStatusCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
