[英]Paypal Checkout client integration - Problem with returning order id promise
我在集成贝宝支付网关时遇到问题。 我将 javascript 用于客户端,python 用于后端和结帐 v2 api。
在后端创建订单没有问题,但是在等待我的服务器响应时 createOrder function 引发错误:
unhandled_error

问题似乎是 createOrder 在引发错误之前没有等待 promise ,或者 promise 没有以正确的方式给出。 类似的东西。 无论如何,这里是客户端代码:
paypal.Buttons({
// button styling removed for clarity
createOrder: function() {
// purchase information
var data = {
'track_id': vm.selectedTrack.id,
'lease_id': vm.selectedLease.id,
}
// post req to api with lease and track ids
// create payment on server side
fetch('http://localhost:5000/api/paypal/create-purchase', {
method: 'post',
headers: {
'content-type': 'application/json'
},
body: JSON.stringify(data),
}).then(function(res) {
return res.json();
}).then(function(data) {
console.log(data.order_id)
return data.order_id
})
}
// conatiner element to render buttons in
}).render('#paypal-button');
和服务器端:
@app.route('/api/paypal/create-purchase', methods=['POST'])
def paypal_create_purchase():
# cart validation removed for clarity
# create paypal purchase
environment = SandboxEnvironment(client_id=app.config['PAYPAL_PUBLIC'], client_secret=app.config['PAYPAL_PRIVATE'])
client = PayPalHttpClient(environment)
paypal_request = OrdersCreateRequest()
paypal_request.prefer('return=representation')
paypal_request.request_body (
{
"intent": "CAPTURE",
"purchase_units": [
{
"amount": {
"currency_code": "USD",
"value": lease.price
}
}
]
}
)
try:
# Call API with your client and get a response for your call
response = client.execute(paypal_request)
order = response.result
print(order.id)
except IOError as ioe:
print (ioe)
if isinstance(ioe, HttpError):
# Something went wrong server-side
print(ioe.status_code)
# note that it is the same key as on the client
return jsonify(success=True,order_id=order.id)
我发现了这个类似的线程,但我不认为错误的来源与该线程中的相同(客户端上的 json 密钥不正确)
另请参阅提供此代码的文档中的相关页面:
createOrder: function() {
return fetch('/my-server/create-paypal-transaction', {
method: 'post',
headers: {
'content-type': 'application/json'
}
}).then(function(res) {
return res.json();
}).then(function(data) {
return data.orderID; // Use the same key name for order ID on the client and server
});
}
该死的,就在我输入帖子的最后一部分时,我注意到了错误。 在我的 fetch 调用之前缺少return
。 会把这个留给有同样错误的其他人。
