虚拟卡相信很多人都不陌生，尤其是在海外购物的时候虚拟卡的作用就尤为重要。很多人不愿意绑定自己的信用卡。又有很多海外平台不支持国内的信用卡。这时候虚拟卡就是很好的一个平替方案。随用随充，不用就注销。那么我们开发这套虚拟信用卡系统最关键的点就是接口。接口我们用stripe提供的接口。以下是我们开源的部分代码

**接口代码**

`from flask import Flask, render_template, request import stripe

app = Flask(name)

设置Stripe API密钥

stripe.api_key = 'YOUR_STRIPE_SECRET_KEY'

@app.route('/') def index(): return render_template('index.html')

@app.route('/checkout', methods=['POST']) def checkout(): if request.method == 'POST': # 获取订单金额（以分为单位） order_amount = int(request.form['order_amount']) * 100

    try:
        # 创建虚拟信用卡 PaymentMethod
        payment_method = stripe.PaymentMethod.create(
            type="card",
            card={
                "number": "4242424242424242",
                "exp_month": 12,
                "exp_year": 2024,
                "cvc": "123",
            },
        )

        # 创建 PaymentIntent
        payment_intent = stripe.PaymentIntent.create(
            amount=order_amount,
            currency='usd',
            payment_method=payment_method.id,
            confirmation_method='manual',
            confirm=True,
        )

        return render_template('checkout.html', client_secret=payment_intent.client_secret)

    except stripe.error.CardError as e:
        return f'Error: {e.error.message}'

if name == 'main': app.run(debug=True) `

**然后我们提供处理逻辑代码**

`from flask_mail import Mail, Message import os

app = Flask(name)

设置Flask-Mail

app.config['MAIL_SERVER'] = 'smtp.example.com' app.config['MAIL_PORT'] = 587 app.config['MAIL_USE_TLS'] = True app.config['MAIL_USE_SSL'] = False app.config['MAIL_USERNAME'] = 'your_email@example.com' app.config['MAIL_PASSWORD'] = 'your_email_password'

mail = Mail(app)

存储支付成功的订单信息

successful_orders = []

...

@app.route('/checkout', methods=['POST']) def checkout(): if request.method == 'POST': order_amount = int(request.form['order_amount']) * 100

    try:
        payment_method = stripe.PaymentMethod.create(
            type="card",
            card={
                "number": "4242424242424242",
                "exp_month": 12,
                "exp_year": 2024,
                "cvc": "123",
            },
        )

        payment_intent = stripe.PaymentIntent.create(
            amount=order_amount,
            currency='usd',
            payment_method=payment_method.id,
            confirmation_method='manual',
            confirm=True,
        )

        # 处理支付成功
        handle_successful_payment(payment_intent)

        return render_template('checkout.html', client_secret=payment_intent.client_secret)

    except stripe.error.CardError as e:
        return f'Error: {e.error.message}'

处理支付成功的函数

def handle_successful_payment(payment_intent): order_details = { 'order_id': payment_intent.id, 'amount': payment_intent.amount / 100, # 转换为美元 'status': payment_intent.status, }

# 存储支付成功的订单信息
successful_orders.append(order_details)

# 发送确认邮件
send_confirmation_email(order_details)

发送确认邮件的函数

def send_confirmation_email(order_details): msg = Message('支付确认', sender='your_email@example.com', recipients=['customer_email@example.com']) msg.body = f"感谢您的支付！订单详情：\n订单ID: {order_details['order_id']}\n支付金额: ${order_details['amount']}\n状态: {order_details['status']}"

# 发送邮件
try:
    mail.send(msg)
except Exception as e:
    print(f"邮件发送失败: {e}")
