如果我有 Stripe 卡令牌，如何检索客户 ID？

我的应用程序使用设计来创建新用户，并将其与 Stripe 集成。

当我创建新客户时，我会返回（作为响应）一个令牌，该令牌是卡的令牌。有没有办法使用该令牌检索客户的 ID？

我有一个相关问题 https://stackoverflow.com/q/21455575这显示了我当前的实现。我提出这个问题是因为我现在明白问题是我在创建新客户期间没有检索/存储客户的 ID。

任何提示都是有价值的。谢谢。

我的 JS（咖啡脚本）

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

user =
  setupForm: ->
    $('#new_user').submit ->
      $('input[type=submit]').attr('disabled', true)
      if $('#card_number').length
        user.processCard()
        false
      else
        true

  processCard: ->
    card =
      number: $('#card_number').val()
      cvc: $('#card_code').val()
      expMonth: $('#card_month').val()
      expYear: $('#card_year').val()
    Stripe.createToken(card, user.handleStripeResponse)

  handleStripeResponse: (status, response) ->
    if status == 200
      $('#user_stripe_card_token').val(response.id)
      $('#new_user')[0].submit()
    else
      $('#stripe_error').text(response.error.message)
      $('#stripe_error').show()
      $('input[type=submit]').attr('disabled', false)

我在控制器中没有做任何事情。我只在我的 user.rb 中使用它：

 after_create :create_a_customer

 def create_a_customer
    token = self.stripe_card_token
    customer = Stripe::Customer.create(
      :card => token,
      :plan => 1,
      :email => self.email
      )         
  end

我们的 JS 看起来相同，所以我想我应该发布我的表单和控制器操作以及对用户进行一些处理和保存的模型。如果有帮助，请告诉我！抱歉，我似乎找不到确切的错误，但我知道，对我来说，有一个有效的示例来查看总是有帮助的！

FORM --

<%= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => {:class => 'form card_form' }) do |f| %>

  <%= f.email_field :email, :required => true, :class => "deviseFormInput", :placeholder => "EMAIL" %><br />
  <i>PASSWORD MINIMUM OF 6 CHARACTERS</i>
  <%= f.password_field :password, :required => true, :class => "deviseFormInput", :placeholder => "PASSWORD" %>
  <%= f.password_field :password_confirmation, :required => true, :class => "deviseFormInput", :placeholder => "PASSWORD CONFIRMATION" %>
  <div class="field">
    <%= f.input :meatless, as: :boolean, :class => "deviseFormInput", :label => "I AM A VEGETARIAN" %>
  </div>
  <%= f.input :comments, as: :text, :placeholder => "ALLERGIES OR INTOLERANCES", :label => false, input_html: { class: 'deviseFormInput', style: 'width: 280px; height: 100px;' } %>

  <% if @user.stripe_customer_token %>
    <p>Credit card acceptance is pending.</p>
  <% else %>
    <div class="field">
      <%= text_field_tag :card_number, nil, name: nil, :class => "deviseFormInput", :placeholder => "CREDIT CARD NUMBER" %>
    </div>
    <div class="field">
      <%= text_field_tag :card_code, nil, name: nil, :class => "deviseFormInput", :placeholder => "CARD SECURITY CODE (CVV)" %>
    </div>
    <div class="field">
      <%= label_tag :card_month, "CARD EXPIRATION" %>
      <br>
      <div class="presser presserDeep">
        <%= select_month nil, {add_month_numbers: true}, {name: nil, id: "card_month"} %>
      </div>
      <div class="presser">
        <%= select_year nil, {start_year: Date.today.year, end_year: Date.today.year+10}, {name: nil, id: "card_year"}%>
      </div>
    </div>
  <% end %>
  <%= f.hidden_field :stripe_card_token %>
  <%= f.button :submit, 'SIGN UP', :class => 'deviseBtn' %>

<% end %>

控制器 -

def create
  shopping_cart_id = session[:shopping_cart_id]
  @shopping_cart = session[:shopping_cart_id] ? ShoppingCart.find(shopping_cart_id) : ShoppingCart.create
  session[:shopping_cart_id] = @shopping_cart.id
  @user = User.new(params[:user])
  if @user.save_with_payment
    sign_in @user
    redirect_to root_path, :notice => "Thank you for signing up!"
  else
    render :new
  end
end

模型（用于 save_with_ payment 方法）--

def save_with_payment
  if valid?
    customer = Stripe::Customer.create(description: email, card: stripe_card_token)
    self.stripe_customer_token = customer.id
    self.last_4_digits = customer.cards.data.first["last4"]
    save!
  end
rescue Stripe::InvalidRequestError => e
  logger.error "Stripe error while creating customer: #{e.message}"
  errors.add :base, "There was a problem with your credit card."
  false
end
