必须提供来源或客户。导轨

Question

当我尝试运行我的代码时，我收到了上面的错误。我不明白为什么我会得到这个，一切对我来说似乎都很清楚..

这是我的控制器的创建操作：

def create
    @user = current_user
    @order = current_order
    @amount = @order.subtotal
    token = params[:stripeToken]

  charge = Stripe::Charge.create(
    :amount      => (@amount.to_i * 100),
    :description => 'Rails Stripe customer',
    :currency    => 'eur',
    :source      => token
  )

  redirect_to root_path

rescue Stripe::CardError => e
  flash[:error] = e.message
  render 'new'
end

我的表格：

<%= form_tag pay_path, html: { id: 'payment-form' }  do %>
<div class="row">
</div>
<div class="row">
  <div style="position: absolute; left: 20px">
    <label class="control-label" for="email">Email</label>
    <input type="email" name="email" id="email" placeholder="you@example.com" style="width: 25em"/>
  </div>
  <div style="position: absolute; left: 400px">
    <label class="control-label" for="number">Card Number</label>
    <input type="text" size="20" data-stripe="number" id="number" placeholder="**** **** **** ****" pattern="[\d ]*" style="width: 18em"/>

    <input style="width: 2em" type="text" size="2" id="exp-month" data-stripe="exp-month" placeholder="MM" pattern="\d*"/>
    <span> / </span>
    <input style="width: 3em" type="text" size="4" id="exp-year" data-stripe="exp-year" placeholder="YYYY" pattern="\d*"/>
  </div>
</div>
<div class="row" style="margin-top: 70px">
  <div class="price" style="position: absolute; left: 20px;"><%= @amount %></div>
  <div style="position: absolute; left: 400px">
    <button type="submit" class="btn btn-primary btn-large">Buy Now</button>
  </div>
</div>

我的布局/application.html.erb：

<script type="text/javascript" src="https://js.stripe.com/v2/">    </script>
<script type="text/javascript">
$(function(){
  Stripe.setPublishableKey('<%=    Rails.configuration.stripe[:publishable_key] %>');
});
</script>

我看到了很多关于这个主题的资源，但没有一个能帮助我。 任何想法 ？

编辑：

routes.rb：

post '/payer-la-commande', to: 'transactions#create',   as: :pay

来自条带日志，解析的请求 POST 正文：

Answer 1

params[:stripeToken] 是空白的，因为您缺少将表单发送到条带、获取令牌值、将其置于隐藏字段并将其发送到服务器 (rails) 的 javascript，请参阅 https://stripe.com/docs/tutorials/forms#create-a-single-use-token 了解更多信息。

编辑：获得令牌后，您必须使用 https://stripe.com/docs/tutorials/forms#sending-the-form-to-your-server 之类的方式将其发送到服务器（与以前相同的文档，只需完整阅读）
