Chargify API 优惠券创建

发布于 2024-11-18 08:32:57 字数 894 浏览 1 评论 0原文

我目前正在开展一个项目并面临任务问题。我正在尝试随机生成一个 6 位优惠券号码并通过 API 将其发布到 Chargify 帐户。如果优惠券创建成功，我希望通过电子邮件将相同的优惠券代码发送给客户。

根据 chargify 文档，这是我应该如何从我的应用程序发送所有详细信息到 chargify：

{"subscription":{
      "product_handle":"[@product.handle]",
      "customer_attributes":{
        "first_name":"Joe",
        "last_name":"Blow",
        "email":"[email protected]"
      },
      "credit_card_attributes":{
        "full_number":"1",
        "expiration_month":"10",
        "expiration_year":"2020"
      },
      "coupon_code":"6 digit random code"
    }}
    """

https://[@subdomain].chargify.com/subscriptions.json。

我可以通过这种方法创建 6 位随机数字代码：

rand(999999).to_s.center(6, rand(9).to_s).

但这似乎对我不起作用。任何建议将不胜感激。

谢谢

I am currently working on a project and facing a problem with a task. I am trying to randomly generate a 6 digit coupon number and post it to chargify account via there API. If the coupon creation is successful I want the same coupon code to be send to the customer through Email.

As per chargify documentation this is how I should send all the details to chargify from my application :

{"subscription":{
      "product_handle":"[@product.handle]",
      "customer_attributes":{
        "first_name":"Joe",
        "last_name":"Blow",
        "email":"[email protected]"
      },
      "credit_card_attributes":{
        "full_number":"1",
        "expiration_month":"10",
        "expiration_year":"2020"
      },
      "coupon_code":"6 digit random code"
    }}
    """

https://[@subdomain].chargify.com/subscriptions.json.

I am able to create a 6 digit random numerical code by this method :

rand(999999).to_s.center(6, rand(9).to_s).

However this does not seem to be working for me. Any suggestions would be highly appreciated.

Thanks

我不是我们的技术或开发人员，但我 99% 确定您只能在该 API 调用中指定先前定义的优惠券代码。您必须在 Chargify 管理 Web 界面中定义优惠券代码。在上面的 API 调用中，您可以将优惠券应用于订阅，但假设您已经在管理界面中定义了该优惠券代码。

我们将来会添加该功能，但我没有具体的日期。

对此感到抱歉。

我不确定您想通过调用 center 来做什么。最明智的做法是将优惠券代码清零。这样就可以了：

"%06d" % rand(1000000)

这将生成诸如“664001”和“061532”之类的代码。

请注意，您需要 rand(1000000) 而不是 rand(999999)。这是因为 rand 为您提供 0 到比参数小 1 之间的随机整数。 rand(999999) 只会给你最大 999998 的随机数。

上面的代码违反了 DRY（不要重复自己）：“06”和“1000000”都依赖于优惠券代码的长度。解决方法如下：

COUPON_CODE_LENGTH = 6
"%0#{COUPON_CODE_LENGTH}d" % rand(10 ** COUPON_CODE_LENGTH)

虽然更长，但如果优惠券代码长度发生变化，现在只需更改一件事。用命名常量替换“幻数”也有助于代码传达其意图。

I'm not sure what you're trying to do with your call to center. The most sensible thing to do would be to zero-fill the coupon code. This would do it:

"%06d" % rand(1000000)

This will generate codes such as "664001" and "061532".

Note that you want rand(1000000) rather than rand(999999). That's because rand gives you random integers between 0 and one less than the argument. rand(999999) will only give you random numbers up to 999998.

There's a violation of DRY (Don't Repeat Yourself) in the above code: Both the "06" and the "1000000" depend upon the length of the coupon code. Here's a fix for that:

COUPON_CODE_LENGTH = 6
"%0#{COUPON_CODE_LENGTH}d" % rand(10 ** COUPON_CODE_LENGTH)

Although longer, there's now only one thing to change if the coupon code length should change. The replacement of "magic numbers" with a named constant also helps the code to communicate its intent.
