因此，我试图使传递的动态总额传递到ruby脚本中的创建支付意图中的金额，并且我在创建支付意图中得到500错误，并且它说payment.js中的fetch创建支付意图存在错误（总额正确传递）
document.addEventListener('DOMContentLoaded', async () => {
// Fetch publishable key from the server
const { publishableKey } = await fetch('/config').then(r => r.json());
const stripe = Stripe(publishableKey);
// Fetch the total amount from the DOM
const totalSpan = document.getElementById("total");
const total = parseFloat(totalSpan.textContent.replace("$", ""));
console.log(total)
// Create payment intent on the server
const { clientSecret } = await fetch("/create-payment-intent", {
method: "POST",
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({ total: total })
}).then(r => r.json());
// Render payment element
const elements = stripe.elements({ clientSecret });
const paymentElement = elements.create('payment', {
fields: {
billingDetails: {
name: 'auto',
email: 'auto',
}
}
});
paymentElement.mount('#payment-element');
const nameInput = document.getElementById('name');
const emailInput = document.getElementById('email');
const form = document.getElementById('payment-form');
form.addEventListener('submit', async (e) => {
e.preventDefault();
// Get the values from the input fields
const name = nameInput.value;
const email = emailInput.value;
// Confirm the payment and redirect to the return URL
const { error } = await stripe.confirmPayment({
elements,
confirmParams: {
return_url: window.location.origin + '/complete',
payment_method_data: {
billing_details: {
name: name,
email: email,
}
},
},
});
if (error) {
const messages = document.getElementById('error-messages');
messages.innerText = error.message;
}
});

通过查看Ruby代码和HTML，我可以确定可能导致创建付款意图的500错误的几个问题。
1./create-payment-intent路由中缺少数据变量：在/create-payment-intent路由中，您引用了data ['total']来检索总金额，但没有定义data变量。要解决这个问题，您需要将请求主体解析为JSON以访问total值。修改代码如下：
post '/create-payment-intent' do request_payload = JSON.parse（request.body.read）total = request_payload['total'].to_i
payment_intent = Stripe：：PaymentIntent.create（{ amount：货币共计：'usd'，automatic_payment_methods：{ enabled：true } }）
{ clientSecret：payment_intent.client_secret }.to_json end
const { clientSecret } = await fetch（“/create-payment-intent”，{ // ...}）;
然而，在Ruby代码中，实际的路由被定义为post '/create-payment-intent' do。确保JavaScript和Ruby代码中的端点路径匹配。
应用这些更改后，请再次尝试运行代码，以查看500错误是否已解决。如果您遇到任何其他问题或错误消息，请提供更多详细信息，我很乐意为您提供进一步帮助。
