如何使用ActiveMerchant和PayPal Express跳过订单确认页面

# 设置PayPal Express支付网关
gateway = ActiveMerchant::Billing::PaypalExpressGateway.new(
  login: 'your_paypal_username',
  password: 'your_paypal_password',
  signature: 'your_paypal_signature'
)

# 创建新订单
order = Order.create(
  name: 'John Doe',
  address: '123 Main St',
  city: 'Anytown',
  state: 'CA',
  zip: '12345',
  email: 'johndoe@example.com',
  total: 10.00
)

# 设置订单金额和货币类型
response = gateway.setup_purchase(order.total,
  ip: request.ip,
  return_url: 'http://example.com/success',
  cancel_return_url: 'http://example.com/cancel',
  currency: 'USD'
)

# 授权订单
authorization = gateway.authorize(order.total, response.token)

# 捕获订单
response = gateway.capture(order.total, authorization.authorization)

# 存储付款信息以跳过订单确认页面
response = gateway.store(response.token)

# 存储付款信息以便将来捕获订单
order.update(payment_token: response.token)
