Question

我在我的ruby on rails项目中使用了paypal-express gem。我正在尝试实施Paypal定期付款。

我能够成功完成expresscheckout，但是我面临上述无效令牌错误的定期付款。我正在做一切正常，如paypal-express gem wiki中所述。无法弄清楚这有什么问题。

def paypal_checkout
    Paypal.sandbox! if Rails.env.development?
    request = Paypal::Express::Request.new(
      :username   => "USERNAME",
      :password   => "PASSWORD",
      :signature  => "SIGNATURE"
    )
    payment_request = Paypal::Payment::Request.new(
      :currency_code => :USD,
      :billing_type  => :RecurringPayments,
      :billing_agreement_description => "Recurring"
    )
    response = request.setup(
      payment_request,
      root_url,
      root_url
    )
    uri = response.redirect_uri
    token = CGI.parse(uri)['token'].join #here I successfully get the response token

    profile = Paypal::Payment::Recurring.new(
      :start_date => Date.today,
      :description => "Recurring",
      :billing => {
        :period        => :Week,
        :frequency     => "1",
        :amount        => "15",
        :currency_code => :USD
      }
    )
    response = request.subscribe!(token, profile) # here i face the 'invalid token error'

  end

payment_request_response =

#<Paypal::Payment::Request:0x007fa3ca7b3a20 @amount=#<Paypal::Payment::Common::Amount:0x007fa3ca7b39d0 @total=0, @item=0, @fee=0, @handing=0, @insurance=0, @ship_disc=0, @shipping=0, @tax=0, @gross=0, @net=0>, @items=[], @custom_fields={}, @action=nil, @currency_code=:USD, @description=nil, @notify_url=nil, @billing_type=:RecurringPayments, @billing_agreement_description="Recurring billing description", @billing_agreement_id=nil, @request_id=nil, @seller_id=nil, @invoice_number=nil, @custom=nil>
