我正在尝试设置PayPal以在我的网站上进行付款，并且我想为付款指定订单项（使用新的SDK，而不是javascript版本）
我尝试过这里列出的API文档：https://developer.paypal.com/docs/api/orders/v2/。但是，它说我要么语法无效，要么我错过了一个字段。
<head>
<script>
paypal.Buttons({
createOrder: function(data, actions) {
return actions.order.create({
purchase_units: [{
amount: {
currency_code: 'USD',
value: '0.01',
amount_breakdown: {
}
},
items: {
item: {
name: 'Cake',
quantity:'1',
unit_amount:{
currency_code:'USD',
value:'0.01'
}
}
}
}],
application_context: {
shipping_preference: 'NO_SHIPPING',
}
});
},
onApprove: function(data, actions) {
return actions.order.capture().then(function(details) {
alert('Transaction completed by ' + details.payer.name.given_name);
// Call your server to save the transaction
return fetch('/paypal-transaction-complete', {
method: 'post',
body: JSON.stringify({
orderID: data.orderID
})
});
});
}
}).render('#paypal-button-container');
</script>
</head>
<body>
<div id="paypal-button-container"></div>
</body>
这是buy_units的正确代码。从这里获取它：
https://github.com/paypal/paypal-checkout-components/issues/1016
purchase_units: [{
amount: {
value: '7',
currency_code: 'USD',
breakdown: {
item_total: {value: '7', currency_code: 'USD'}
}
},
invoice_id: 'muesli_invoice_id',
items: [{
name: 'Hafer',
unit_amount: {value: '3', currency_code: 'USD'},
quantity: '1',
sku: 'haf001'
}, {
name: 'Discount',
unit_amount: {value: '4', currency_code: 'USD'},
quantity: '1',
sku: 'dsc002'
}]
}]
