我一直在关注 Stripe 的教程，使用他们的 API 创建我自己的表单。长话短说，当提交表单时，会发生一些 Javascript 将数据发送到他们的服务器，然后附加 stripeToken输入字段。然后再次提交表单，我的 Flask 应用程序应该读取这个新表单字段的值。但是，当我尝试运行我的代码时，它会产生 500 Internal Server Error，我认为这是因为 Flask 正在立即寻找表单 stripeToken ，第一次检查时不存在。是否有 Javascript 或 Python 我可以添加到不调用 request.form['stripeToken']直到Stripe添加它之后？
这是我的相关 HTML:
<head>
<title>Settings</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="https://js.stripe.com/v1/"></script>
<script type="text/javascript">
// This identifies your website in the createToken call below
Stripe.setPublishableKey('STRIPE_TEST_KEY');
var stripeResponseHandler = function(status, response) {
var $form = $('#payment-form');
if (response.error) {
// Show the errors on the form
$form.find('.payment-errors').text(response.error.message);
$form.find('button').prop('disabled', false);
} else {
// token contains id, last4, and card type
var token = response.id;
// Insert the token into the form so it gets submitted to the server
$form.append($('<input type="hidden" name="stripeToken" id="stripeToken" />').val(token));
// and re-submit
$form.get(0).submit();
}
};
jQuery(function($) {
$('#payment-form').submit(function(e) {
var $form = $(this);
// Disable the submit button to prevent repeated clicks
$form.find('button').prop('disabled', true);
Stripe.createToken($form, stripeResponseHandler);
// Prevent the form from submitting with the default action
return false;
});
});
</script>
</head>
<body>
<div id="payments">
<h1>Add a credit card</h1>
<form action="{{ url_for('stats') }}" method="POST" id="payment-form">
这是Python:
@app.route('/stats', methods=['GET', 'POST'])
def stats():
#if signed in as user
if session['signed-in-accttype'] == 'u':
u=User.query.get(session['signed-in-id'])
if request.method == 'POST':
stripe.api_key = "STRIPE_TEST_KEY"
token = request.form['stripeToken']
customer = stripe.Customer.create(
card=token,
description=u.uemail
)
#update stripe id
u.ustripe_id = customer.id
db.session.commit()
return redirect(url_for('stats'))
return render_template('settings.html', u=u)

更新 2:我推断我的本地测试脚本上的上述错误是因为我忘记了
import stripe .这样做使它运行良好。但是，同样的代码在 Heroku 上运行时会继续产生 500 错误。更新 3(启示):所以我的 Stripe 仪表板说我确实在创建新用户。因此，我认为可以公平地假设直到(包括)
customer = stripe.Customer.create 之前的所有代码作品。那么500错误可能是由我修改数据库引起的吗？
最佳答案
NameError:未定义全局名称“Stripe ”
好像忘记导入 stripe .
