Question

我正在尝试使用PayPal SOAP API执行TransactionSearchReq方法，并收到以下警告：

ShortMessage：搜索警告

LongMessage：结果数被截断。如果您希望查看所有结果，请更改搜索参数。

ErrorCode：11002

SeverityCode：警告

它还在文档中说“可以从TransactionSearch API调用返回的最大事务数为100”。（https://developer.paypal.com/docs/classic/api/merchant/TransactionSearch_API_Operation_SOAP/）

是否有某种方式对结果进行分页，以便从多个查询中获得100多个结果？

这是你在Rails中可以做到的一种方法。这假设您要从特定时间点开始搜索，但您可以更改end_date以指定结束日期。请注意，我已将'paypal-sdk-merchant' gem添加到我的gemfile（请参阅https://github.com/paypal/merchant-sdk-ruby）并按照说明设置我的身份验证。

您要在下面编辑的两件事是start_date方法（设置您自己的开始日期）和do_something(x)方法，这将是您想要对每个方法做的任何事情。您日期范围内的个别订单。

module PaypalTxnSearch
  def check_for_updated_orders
    begin
      @paypal_order_list = get_paypal_orders_in_range(start_date, end_date)

      @paypal_order_list.PaymentTransactions.each do |x|
        # This is where you can call a method to process each transaction
        do_something(x)
      end
      # TransactionSearch returns up to 100 of the most recent items.
    end while txn_search_result_needs_pagination?
  end

  def get_paypal_orders_in_range(start_date, end_date)
    @api = PayPal::SDK::Merchant::API.new
    # Build Transaction Search request object
    # https://developer.paypal.com/webapps/developer/docs/classic/api/merchant/TransactionSearch_API_Operation_NVP/
    @transaction_search = @api.build_transaction_search(
      StartDate: start_date,
      EndDate: end_date
    )
    # Make API call & get response
    @response = @api.transaction_search(@transaction_search)
    # Access Response
    return_response_or_errors(@response)
  end

  def start_date
    # In this example we look back 6 months, but you can change it 
    Date.today.advance(months: -6)
  end

  def end_date
    if defined?(@paypal_order_list)
      @paypal_order_list.PaymentTransactions.last.Timestamp
    else
      DateTime.now
    end
  end

  def txn_search_result_needs_pagination?
    @@paypal_order_list.Ack == 'SuccessWithWarning' &&
      @@paypal_order_list.Errors.count == 1 &&
      @@paypal_order_list.Errors[0].ErrorCode == '11002'
  end

  def return_response_or_errors(response)
    if response.success?
      response
    else
      response.Errors
    end
  end
end

是否有交易搜索的分页？
