为什么即使没有到期年份，Stripe 也会生成卡令牌？

Question

我在user.rb中有以下方法：

  def create_card(params)
    begin
      token = Stripe::Token.create(:card => {
        :number => params["number"],
        :exp_month => params["expiry_month"],
        :exp_year => params["expiry_year"],
        :cvc => params["cvc"]})
    rescue Stripe::CardError => card
    end
    if token.present?
      begin
        card_object = Stripe::Customer.create(:card => token.id, :description => "#{token.card.type} #{token.card.last4}")
      rescue Stripe::CardError => card
      end
    end
    if card_object.present?
      card = self.cards.create! :card_id => card_object.id, :brand => token.card.type, :display_number => token.card.last4, :expiry_month => token.card.exp_month, :expiry_year => token.card.exp_year
    end
    return card
  end

即使我向它提供了不正确的卡片信息，它也会生成令牌（和卡片），所以我使用 Pry 进入了该方法。这是我看到的：

> params
=> {"number"=>"4242424242424242", "cvc"=>"123", "expiry_month"=>"12", "expiry_year"=>""}
> token = Stripe::Token.create(:card => {
    :number => params["number"],
    :exp_month => params["expiry_month"],
    :exp_year => params["expiry_year"],
    :cvc => params["cvc"]})
=> #<Stripe::Token:0x3ffec3d0e9d4 id=test_tok_1> JSON: {
  "id": "test_tok_1",
  "livemode": false,
  "used": false,
  "object": "token",
  "type": "card",
  "card": {"id":"test_cc_2","object":"card","last4":"4242","type":"Visa","brand":"Visa","funding":"credit","exp_month":"12","exp_year":"","fingerprint":"eXWMGVNbMZcworZC","customer":"test_cus_default","country":"US","name":"Johnny App","address_line1":null,"address_line2":null,"address_city":null,"address_state":null,"address_zip":null,"address_country":null,"cvc_check":null,"address_line1_check":null,"address_zip_check":null,"number":"4242424242424242","cvc":"123"}
}

为什么要生成令牌？

当我检查此方法 returns 的卡片对象时，我得到：

> card
+----+------------+----------------+--------------+-------------+-------+-------------------------+-------------------------+----------+---------+
| id | card_id    | display_number | expiry_month | expiry_year | brand | created_at              | updated_at              | order_id | user_id |

Answer 1

您好像提供了后续的卡号参数。所有的测试号都是documented here.

无论您是否指定了有效的到期年份，此特定号码将始终成功。

如果您尝试提出 expired_card CardError，请尝试使用 4000000000000069

Answer 2

这绝对不应该起作用：

[1] pry(main)> require "stripe"
=> true
[2] pry(main)> Stripe.api_key = "sk_test_..."
=> "sk_test_..."
[3] pry(main)> params = {"number"=>"4242424242424242", "cvc"=>"123", "expiry_month"=>"12", "expiry_year"=>""}
=> {"number"=>"4242424242424242",
 "cvc"=>"123",
 "expiry_month"=>"12",
 "expiry_year"=>""}
[4] pry(main)> token = Stripe::Token.create(:card => {
[4] pry(main)*     :number => params["number"],
[4] pry(main)*     :exp_month => params["expiry_month"],
[4] pry(main)*     :exp_year => params["expiry_year"],
[4] pry(main)* :cvc => params["cvc"]})
Stripe::CardError: Your card's expiration year is invalid.
from /usr/local/lib/ruby/gems/2.3.0/gems/stripe-1.36.0/lib/stripe.rb:310:in `handle_api_error'

我建议您检查仪表板中的 logs 以找出令牌创建请求的实际内容。

为什么即使没有到期年份，Stripe 也会生成卡令牌？

Why is Stripe generating a card token even when the expiry year is absent?
