如何在ruby rails中重用多个API调用中的异常处理？

# app/exceptions/api_exception.rb
class APIException < StandardError
  attr_reader :status, :message

  def initialize(status, message)
    @status = status
    @message = message
  end
end

# app/services/api_service.rb
class APIService
  def self.call_api(url, params)
    response = HTTParty.get(url, params)
    
    if response.code == 200
      response.parsed_response
    else
      raise APIException.new(response.code, response.message)
    end
  rescue APIException => e
    # 处理自定义异常
    Rails.logger.error("API Exception: #{e.message}")
    # 可以选择记录日志、发送通知等操作
    # ...
  rescue StandardError => e
    # 处理其他异常
    Rails.logger.error("Unexpected Exception: #{e.message}")
    # ...
  end
end

# app/controllers/api_controller.rb
class APIController < ApplicationController
  def index
    begin
      response = APIService.call_api('https://api.example.com', {})
      render json: response
    rescue APIException => e
      render json: { error: e.message }, status: e.status
    rescue StandardError => e
      render json: { error: 'Unexpected error occurred' }, status: :internal_server_error
    end
  end
end
