快速入门指南

安装与配置

通过RubyGems安装Active Merchant:

# Gemfile
gem 'activemerchant'

# 或直接安装
gem install activemerchant

基础使用示例

以下是一个完整的支付处理示例:

require 'active_merchant'

# 设置测试模式
ActiveMerchant::Billing::Base.mode = :test

# 初始化支付网关(以Stripe为例)
gateway = ActiveMerchant::Billing::StripeGateway.new(
  login: 'sk_test_your_api_key'
)

# 创建信用卡对象
credit_card = ActiveMerchant::Billing::CreditCard.new(
  first_name: 'John',
  last_name: 'Doe',
  number: '4242424242424242',
  month: '12',
  year: '2025',
  verification_value: '123'
)

# 验证信用卡信息
if credit_card.valid?
  # 执行支付(金额以分为单位)
  amount = 1000  # $10.00
  response = gateway.purchase(amount, credit_card)
  
  if response.success?
    puts "支付成功!交易ID: #{response.authorization}"
  else
    puts "支付失败: #{response.message}"
  end
else
  puts "信用卡信息无效: #{credit_card.errors.full_messages.join(', ')}"
end

核心功能深度解析

1. 支付操作类型

Active Merchant支持多种支付操作,满足不同业务场景需求:

操作类型方法名描述适用场景
即时支付purchase授权并立即扣款普通商品购买
预授权authorize只授权不扣款酒店预订、租车
扣款capture对预授权进行扣款确认交易完成
退款refund退还已扣款项客户退货
撤销void取消未完成的交易交易错误

2. 信用卡处理

Active Merchant提供了强大的信用卡处理能力:

# 信用卡验证示例
credit_card = ActiveMerchant::Billing::CreditCard.new(
  first_name: 'Alice',
  last_name: 'Smith',
  number: '4111111111111111',
  month: '10',
  year: '2026',
  brand: 'visa'
)

# 自动检测卡类型
puts "卡类型: #{credit_card.brand}"  # 输出: visa

# 验证卡片有效性
if credit_card.valid?
  puts "信用卡验证通过"
else
  puts "验证错误: #{credit_card.errors}"
end

3. 地址信息处理

高级功能与最佳实践

1. 错误处理与重试机制

def process_payment_with_retry(gateway, amount, credit_card, options, max_retries = 3)
  retries = 0
  
  begin
    response = gateway.purchase(amount, credit_card, options)
    
    if response.success?
      return { success: true, data: response }
    else
      # 根据错误码决定是否重试
      if should_retry?(response.params['error_code'])
        retries += 1
        raise "支付失败,进行第#{retries}次重试"
      else
        return { success: false, error: response.message }
      end
    end
  rescue => e
    if retries < max_retries
      sleep(2 ** retries)  # 指数退避
      retry
    else
      return { success: false, error: "支付失败: #{e.message}" }
    end
  end
end

def should_retry?(error_code)
  # 可重试的错误码(如网络超时、临时系统错误)
  retryable_errors = ['timeout', 'system_busy', 'temporary_error']
  retryable_errors.include?(error_code)
end

2. 交易状态管理

class PaymentProcessor
  def initialize(gateway)
    @gateway = gateway
    @transactions = {}
  end
  
  def create_payment(amount, credit_card, options = {})
    response = @gateway.purchase(amount, credit_card, options)
    
    if response.success?
      transaction = {
        id: response.authorization,
        amount: amount,
        status: 'completed',
        timestamp: Time.now,
        raw_response: response.params
      }
      @transactions[transaction[:id]] = transaction
      transaction
    else
      { error: response.message, status: 'failed' }
    end
  end
  
  def refund_payment(transaction_id, amount = nil)
    transaction = @transactions[transaction_id]
    return { error: '交易不存在' } unless transaction
    
    response = @gateway.refund(amount || transaction[:amount], transaction_id)
    
    if response.success?
      transaction[:status] = 'refunded'
      transaction[:refunded_at] = Time.now
      { success: true, refund_id: response.authorization }
    else
      { error: response.message }
    end
  end
end

3. 安全最佳实践

# 敏感信息处理
class SecurePaymentHandler
  def self.sanitize_credit_card(params)
    # 移除敏感信息
    sanitized = params.dup
    sanitized.delete(:verification_value)
    sanitized[:number] = mask_credit_card(params[:number])
    sanitized
  end
  
  def self.mask_credit_card(number)
    return unless number
    "XXXX-XXXX-XXXX-#{number.last(4)}"
  end
  
  def self.validate_pci_compliance(credit_card)
    # PCI DSS合规性检查
    errors = []
    
    # 不存储CVV
    errors << "不应存储CVV值" if credit_card.verification_value.present?
    
    # 卡号加密
    errors << "卡号未加密" unless credit_card.number.encrypted?
    
    errors
  end
end

Rails集成示例

# app/models/payment.rb
class Payment < ApplicationRecord
  belongs_to :order
  
  enum status: { pending: 0, completed: 1, failed: 2, refunded: 3 }
  
  def process!
    gateway = ActiveMerchant::Billing::StripeGateway.new(
      login: Rails.application.credentials.stripe[:secret_key]
    )
    
    response = gateway.purchase(
      order.total_cents,
      credit_card_data,
      payment_options
    )
    
    if response.success?
      update!(
        status: :completed,
        transaction_id: response.authorization,
        processed_at: Time.now,
        response_data: response.params
      )
      order.complete!
    else
      update!(
        status: :failed,
        error_message: response.message,
        response_data: response.params
      )
    end
  end
  
  private
  
  def credit_card_data
    {
      number: card_number,
      month: expiry_month,
      year: expiry_year,
      verification_value: cvv,
      first_name: first_name,
      last_name: last_name
    }
  end
  
  def payment_options
    {
      order_id: order.number,
      email: order.email,
      ip: order.ip_address,
      billing_address: order.billing_address.to_active_merchant,
      description: "Order #{order.number}"
    }
  end
end

故障排除与调试

常见问题解决方案

问题现象可能原因解决方案
信用卡被拒绝卡号错误、余额不足验证卡信息、联系发卡行
网络超时网关响应慢、网络问题实现重试机制、检查网络
认证失败API密钥错误、权限不足检查密钥配置、联系网关支持
金额格式错误货币单位不一致确保使用分作为单位

调试技巧

# 启用详细日志
ActiveMerchant::Billing::Base.wiredump_device = File.open('payment.log', 'a+')
ActiveMerchant::Billing::Base.wiredump_device.sync = true

# 测试模式验证
ActiveMerchant::Billing::Base.mode = :test

# 使用测试信用卡号
test_cards = {
  visa: '4242424242424242',
  mastercard: '5555555555554444',
  amex: '378282246310005',
  discover: '6011111111111117'
}

性能优化建议

1. 连接池管理

# 初始化网关连接池
class GatewayConnectionPool
  def initialize
    @pool = {}
    @mutex = Mutex.new
  end
  
  def gateway_for(provider)
    @mutex.synchronize do
      @pool[provider] ||= create_gateway(provider)
    end
  end
  
  private
  
  def create_gateway(provider)
    case provider.to_sym
    when :stripe
      ActiveMerchant::Billing::StripeGateway.new(
        login: Rails.application.credentials.stripe[:secret_key],
        test: Rails.env.test?
      )
    when :paypal
      ActiveMerchant::Billing::PaypalGateway.new(
        login: Rails.application.credentials.paypal[:username],
        password: Rails.application.credentials.paypal[:password],
        signature: Rails.application.credentials.paypal[:signature]
      )
    end
  end
end

2. 批量处理优化

# 批量退款处理
def process_batch_refunds(refund_requests)
  results = []
  
  refund_requests.each_slice(10) do |batch|  # 分批次处理
    batch_results = batch.map do |request|
      Thread.new do
        begin
          response = gateway.refund(request[:amount], request[:transaction_id])
          { success: response.success?, data: response.params }
        rescue => e
          { success: false, error: e.message }
        end
      end
    end
    
    results.concat(batch_results.map(&:value))
    sleep(1)  # 避免速率限制
  end
  
  results
end
