问题描述
按照 https://developer.paypal.com 上的指南进行操作/webapps/developer/docs/integration/web/accept-paypal-payment/ ，我已成功创建付款并重定向用户以批准它.
By following the guide on https://developer.paypal.com/webapps/developer/docs/integration/web/accept-paypal-payment/ , I have successfully created a payment and redirect the user to approve it.
创建的付款如下所示，我将其保存在用户会话中以供进一步参考.
The created payment is something look like bellow, and I save it in user's session for further reference.
{
"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"
}
]
}
在用户批准付款后，Paypal 会将用户重定向到 return_url.例如，http://?token=EC-60U79048BN7719609&PayerID=7E7MGXCWTTKK2.
After user approved the payment, Paypal will redirect the user to the return_url. For example, http://<return_url>?token=EC-60U79048BN7719609&PayerID=7E7MGXCWTTKK2.
为了执行付款，必须向 https://api.sandbox.paypal.com/v1/payments/payment/{payment_id}/execute/ 发出 POST 请求.
In order to execute the payment, a POST request has to made to https://api.sandbox.paypal.com/v1/payments/payment/{payment_id}/execute/.
问题
在 URL 中 Paypal 提供的唯一两条信息是 token 和 PayerID.如何找到对应的payment_id?
The only two pieces of information provided from Paypal in the URL is token and PayerID. How can I find the corresponding payment_id?
可能的解决方案
token 是 approval_url 的一部分，解析 URL 并存储 token ->支付关系可以解决问题.但我正在寻找一个不需要解析的更好的解决方案.
The token is part of the approval_url, parse the URL and store the token -> payment relationship can solve the problem. But I'm looking for a better solution that doesn't require parsing.
推荐答案
我认为 paypal 文档对此并不清楚.但是您可以做一些简单的事情来解决您通过返回网址中的参数传递 de PaymentID 的问题.
I think the paypal documentation isn't clear about this. But you can do something simple to resolve your problem passing de PaymentID through a parameter in your return url.
像这样:return_url = 'http://www.yourdomain.com/paypal/success/?paymentID=PAY-1234567'
Like this: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 和其他参数.
When the Paypal redirect to your site, then, it will return the paymentID together with the other parameters.
葡萄牙语:
Não acho que isso esteja claro na documentação do Paypal.A solução que eu usei foi simples, eu passo o PaymentID como parâmetro na minha URL de retorno que informo para o Paypal.Assim, quando o Paypal redirectionar para meu site de volta ele matem o parâmetro com o PaymentID que eu tinha passado.
