Stripe and Rails 4：此客户没有附加付款来源

Question

在使用 Stripe 订阅计划时，我遇到了非常零星的错误。

点击订阅按钮后，有时会创建用户和订阅，并且我从 Stripe 返回的数据（stripe_id、stripe_subscription_id、card_last4 等）被正确保存。

每隔一段时间我都会遇到以下错误：

Stripe::InvalidRequestError in SubscriptionsController#create

This customer has no attached payment source

when 400, 404
  raise invalid_request_error(error, resp, error_obj)

SubscriptionsController#create

class SubscriptionsController < ApplicationController
  before_action :authorize

  def create
    @user = current_user

    customer =  if current_user.stripe_id?
                  Stripe::Customer.retrieve(current_user.stripe_id)
                else
                  Stripe::Customer.create(email: current_user.email)
                end

    # Get the credit card details submitted by the form
    token = params[:stripeToken]

    subscription = customer.subscriptions.create(
          source: token,
      plan: "monthly"
    )

    @user.attributes = {
      :stripe_id => customer.id,
      :stripe_subscription_id => subscription.id,
      :card_last4 => params[:card_last4],
      :card_exp_month => params[:card_exp_month],
      :card_exp_year => params[:card_exp_year],
      :card_brand => params[:card_brand]
    }

    @user.save(:validate => false)

    redirect_to root_path
  end

end

subscription.js.coffee

jQuery ->
  Stripe.setPublishableKey($("meta[name='stripe-key']").attr("content"))

  $('#payment-form').submit (event) ->
    $form = $(this)
    # Disable the submit button to prevent repeated clicks
    $form.find('button').prop 'disabled', true
    Stripe.card.createToken $form, stripeResponseHandler
    # Prevent the form from submitting with the default action
    false

stripeResponseHandler = (status, response) ->
  $form = $('#payment-form')
  if response.error
    # Show the errors on the form
    $form.find('.payment-errors').text response.error.message
    $form.find('button').prop 'disabled', false
  else
    # response contains id and card, which contains additional card details
    token = response.id
    # Insert the token into the form so it gets submitted to the server
    $form.append $('<input type="hidden" name="stripeToken" />').val(token)

    $form.append $('<input type="hidden" name="card_last4" />').val(response.card.last4)
    $form.append $('<input type="hidden" name="card_exp_month" />').val(response.card.exp_month)
    $form.append $('<input type="hidden" name="card_exp_year" />').val(response.card.exp_year)
    $form.append $('<input type="hidden" name="card_brand" />').val(response.card.brand)
    # and submit
   $form.get(0).submit()
  return

同样，有时付款有效，有时会引发错误。

（我知道关于这个话题的其他问题，但似乎没有人有那些零星的事件）

也许在您的创建下添加debugger，看看有什么异常以及出现在哪里？

class SubscriptionsController <     ApplicationController
  before_action :authorize

  def create
    debugger
    @user = current_user

    customer =  if current_user.stripe_id?
                  Stripe::Customer.retrieve(current_user.stripe_id)
                else
                  Stripe::Customer.create(email: current_user.email)
                end

    # Get the credit card details submitted by the form
token = params[:stripeToken]

    subscription = customer.subscriptions.create(
      source: token,
  plan: "monthly"
)

    @user.attributes = {
      :stripe_id => customer.id,
      :stripe_subscription_id => subscription.id,
      :card_last4 => params[:card_last4],
      :card_exp_month => params[:card_exp_month],
      :card_exp_year => params[:card_exp_year],
      :card_brand => params[:card_brand]
    }

    @user.save(:validate => false)

    redirect_to root_path
  end

end
