PayPal checkout.js-获取paymentID和payerID

Question

<script src='https://www.paypalobjects.com/api/checkout.js'></script>

<div id='paypal-button'></div>

<script>\n";
paypal.Button.render({
// Configure environment
print "env: 'sandbox',
client: {
    sandbox: 'SANDBOX-KEY',
    production: 'PRODUCTION-KEY'
},
// Customize button (optional)\n";
locale: 'de_DE',
style: {
    size: 'small',
    color: 'gold',
    shape: 'pill',
},
// Set up a payment
payment: function (data, actions) {
    return actions.payment.create({
        transactions: [{
            amount: {
                total: '".$price."',
                currency: 'EUR'
            }
        }]
    });
},
// Execute the payment:
// 1. Add an onAuthorize callback
onAuthorize: function(data, actions) {
    return actions.payment.execute({ paymentID: data.paymentID, payerID: data.payerID })
    then(function(res) { window.location.replace ('MY-URL/index.php?func=billing&pp_success=1&paymentID=$paymentID') })
    catch(function(err) { window.location.replace ('MY-URL/index.php?func=billing&pp_error=1') });
},
}, '#paypal-button');
</script> 

有人能告诉我，我需要如何更改代码，以便从事务中获得paymentId和payerID吗？

Answer 1

PayPal签出API

...

actions.payment.execute():()=>promise

...
actions.payment.execute({ ... })
  .then(function(res) { ... res.id /* $paymentID */ ... }) ...
