我正在尝试按照以下手册在我的网页上实现PayPal Checkout（javascript）：https://developer.paypal.com/docs/checkout/ 使用标准选项，一切都很棒。例如，这很好用：
paypal.Buttons({
createOrder: function(data, actions) {
return actions.order.create({
purchase_units: [{
amount: {
currency_code: 'EUR',
value: '120.16'
},
description: 'Purchase Unit test description',
custom_id: '64735',
}]
});
},
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('/api/paypal-transaction-complete', {
method: 'post',
headers: {
'content-type': 'application/json'
},
body: JSON.stringify({
orderID: data.orderID
})
});
});
}
}).render('#paypal-button-container');
但是当我尝试更详细地了解订单详细信息时，它给了我一个错误：
Error: "Order Api response error:
{
"name": "INVALID_REQUEST",
"message": "Request is not well-formed, syntactically incorrect, or violates schema.",
"debug_id": "1ed03d18530c1",
"details": [
{
"location": "body",
"issue": "INVALID_SYNTAX",
"description": "Cannot deserialize instance of `com.paypal.api.platform.checkout.orders.v2.model.AmountBreakdown` out of START_ARRAY token line: 1, column: 82"
}
],
"links": [
{
"href": "https://developer.paypal.com/docs/api/orders/v2/#error-INVALID_SYNTAX", "rel": "information_link", "encType": "application/json"
}
]
}"
}
这是我的代码：
paypal.Buttons({
createOrder: function(data, actions) {
return actions.order.create({
purchase_units: [{
amount: {
currency_code: 'EUR',
value: '120.16',
breakdown: [{
item_total: {
unit_amount: 7,
currency_code: 'EUR',
value: '120.16'
}
}]
},
description: 'Purchase Unit test description',
custom_id: '64735',
items: [{
name: 'Test item 1',
unit_amount: {
currency_code: 'EUR',
value: '60.12'
},
quantity: 2,
description: 'Uaua item 1 description'
}, {
name: 'Test item 2',
unit_amount: {
currency_code: 'EUR',
value: '60.00'
},
quantity: 5,
description: 'Test item 2 description'
}]
}]
});
},
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('/api/paypal-transaction-complete', {
method: 'post',
headers: {
'content-type': 'application/json'
},
body: JSON.stringify({
orderID: data.orderID
})
});
});
}
}).render('#paypal-button-container');
任何人都知道问题出在哪里？ PayPal文档不是非常有用...
答案 0 :(得分：1)
unit_amount：7，
那属于那里吗？您的错误引用了orders.v2.model.AmountBreakdown，并且我在item_total money对象的API规范中没有看到该字段。

经过进一步的挖掘，我发现了正确的格式：
paypal.Buttons({
createOrder: function(data, actions) {
return actions.order.create({
purchase_units: [
{
reference_id: "PUHF",
description: "Some description",
custom_id: "Something7364",
soft_descriptor: "Great description 1",
amount: {
currency_code: "EUR",
value: "200.00",
breakdown: {
item_total: {
currency_code: "EUR",
value: "200.00"
}
}
},
items: [
{
name: "Item 1",
description: "The best item ever",
sku: "xyz-2654",
unit_amount: {
currency_code: "EUR",
value: "100.00"
},
quantity: "1"
},
{
name: "Item 2",
description: "Not bad too",
sku: "zdc-3942",
unit_amount: {
currency_code: "EUR",
value: "50.00"
},
quantity: "2"
}
],
}
]
});
},
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('/api/paypal-transaction-complete', {
method: 'post',
headers: {
'content-type': 'application/json'
},
body: JSON.stringify({
orderID: data.orderID
})
});
});
}
}).render('#paypal-button-container');
这是一整套选项的示例：

paypal.Buttons({
