Paypal REST API：如何在用户批准付款后检索付款ID.

按照 https://developer.paypal.com/webapps/developer/docs/integration/web/accept-paypal-payment/的指南,我已经成功地创建了付款,并重定向了用户以批准它.

创建的支付是一些看起来像bellow,我保存在用户的会话进一步参考.

{
  "id": "PAY-6RV70583SB702805EKEYSZ6Y",
  "create_time": "2013-03-01T22:34:35Z",
  "update_time": "2013-03-01T22:34:36Z",
  "state": "created",
  "intent": "sale",
  "payer": {
    "payment_method": "paypal"
  },
  "transactions": [
    {
      "amount": {
        "total": "7.47",
        "currency": "USD",
        "details": {
          "subtotal": "7.47"
        }
      },
      "description": "This is the payment transaction description."
    }
  ],
  "links": [
    {
      "href": "https://api.sandbox.paypal.com/v1/payments/payment/PAY-6RV70583SB702805EKEYSZ6Y",
      "rel": "self",
      "method": "GET"
    },
    {
      "href": "https://www.sandbox.paypal.com/webscr?cmd=_express-checkout&token=EC-60U79048BN7719609",
      "rel": "approval_url",
      "method": "REDIRECT"
    },
    {
      "href": "https://api.sandbox.paypal.com/v1/payments/payment/PAY-6RV70583SB702805EKEYSZ6Y/execute",
      "rel": "execute",
      "method": "POST"
    }
  ]
}

用户批准付款后,Paypal将重定向到return_url用户.例如,http：//< return_url>？token = EC-60U79048BN7719609& PayerID = 7E7MGXCWTTKK2.

为了执行付款,POST请求必须发送到https://api.sandbox.paypal.com/v1/payments/payment/{payment_id}/execute/.

题

从Paypal在URL中提供的唯一两条信息是token和PayerID.如何找到相应的payment_id？

可能的解决方案

令牌是approval_url的一部分,解析URL并存储令牌 – >付款关系可以解决问题.但是我正在寻找一个不需要解析的更好的解决方案.

我认为paypal文件并不清楚.但是,您可以简单地解决您通过返回URL中的参数传递付款方式的问题.

喜欢这个：
return_url =’http://www.yourdomain.com/paypal/success/？paymentID = PAY-1234567′

当PayPal重定向到您的网站时,它将返回paymentID与其他参数.

Emportuguês：

Paypal是一个不错的选择.一个解决方案,它是一个简单的例子,支付方式PayD comoparâmetrona minha URL de retorno que informo para o Paypal. Assim,quando o Paypal redirecionar para meu site de volta ele matem oparâmetrocom o PaymentID que eu tinha passado.
