Stripe 不接受付款，收费一直失败。我收到此错误：

看起来好像它可能没有创建条纹令牌？这是怎么回事？
这是我的表格：
<% content_for :head do %>
<%= tag :meta, :name => "stripe-key", :content => STRIPE_PUBLIC_KEY %>
<% end %>
<%= form_for @charge, :html => { :class => 'form' } do |f| %>
<div class="form-inputs">
<div class="row">
<%= f.hidden_field :contest_id, value: @contest.id %>
<%= f.hidden_field :user_id %>
<%= f.hidden_field :amount %>
<!-- TODO CHANGE THIS ACCORDINGLY -->
<%= f.hidden_field :stripe_card_token %>
<div class="small-12 medium-6 large-2 columns">
<%= f.label "Amount:", class: "text-right" %>
</div>
<div class="small-12 medium-6 large-10 columns" style="margin-bottom: 0.5rem; margin-top: 0.5rem;">
<%= number_to_currency(@charge.amount, :unit => "$") %>
</div>
<% if @charge.stripe_card_token.present? %>
Credit card has been provided.
<% else %>
<div class="small-12 medium-6 large-2 columns">

<% end %>
<div id="stripe_error">

<div class="row">

<% content_for :js do %>
<%= javascript_include_tag "https://js.stripe.com/v1", "application" %>
<%= javascript_include_tag asset_path("stripe/stripe.js"), "application" %>
<% end %>
这是我的收费控制器：
class ChargesController < ApplicationController
def new
@contest = Contest.find(params[:id])
@charge = Charge.new(amount: params[:amount])
end
def create
@charge = Charge.new(charges_params)
if @charge.save_with_payment(@charge)
redirect_to root_path, :notice => "Contribution was recorded succesfully!"
else
redirect_to root_path, :notice => "Transaction was not able to be recorded"
end
end
def charges_params
params.require(:charge).permit(:stripe_card_token, :contest_id, :user_id, :amount)
end
end
我的收费模式：
class Charge < ActiveRecord::Base
attr_accessor :stripe_card_token
belongs_to :contest
belongs_to :user
def save_with_payment(charge)
if valid?
Stripe::Charge.create(
:amount => (charge.amount.to_i)*100,
:currency => "usd",
:card => stripe_card_token);
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
end
很可能看起来 stripe_card_token 是空白的
:card => stripe_card_token
尝试将其更改为
:card => charge.stripe_card_token与
stripe_card_token来自 Stripe 入门文档：
注意输入字段如何表示敏感卡数据（号码、CVC、 到期月份和年份）没有“名称”属性。这 提交表单时防止他们访问您的服务器。
Rails 标签助手默认生成一个 name 属性。在这种情况下这是不可取的。
您可以通过为
namevalue<%= text_field_tag nil, nil, 'data-stripe' => 'card_number' %>
这里我使用了 Stripe 当前推荐的
data-stripeid回到原来的问题，问题出在您的 Charge 模型中，您在其中覆盖 Active Record 并屏蔽数据库中的数据：
class Charge < ActiveRecord::Base
attr_accessor :stripe_card_token # Don't do this!
attr_accessorirb(main):001:0> Charge.first
Charge Load (0.3ms) SELECT "charges".* FROM "charges" ORDER BY "charges"."id" ASC LIMIT 1
=> #<Charge id: 1, stripe_card_token: "0xdeadbeef", created_at: "2014-06-11 14:27:40", updated_at: "2014-06-11 14:27:40">
irb(main):002:0> c.stripe_card_token
=> nil
话虽如此，您开始使用的 Railscast 已经有近三年的历史了，到处都违反了最佳实践，并且使用了早已过时的 API 端点。一旦你纠正了你的模型，你仍然最好开始你的表单和 JavaScript，而不是使用 Stripe 的当前教程和文档。
我遇到了同样的问题。
我的subscription.js.coffee：
jQuery ->
Stripe.setPublishableKey($('meta[name="stripe-key"]').attr('content'))
subscription.setupForm()
subscription =
setupForm: ->
$('#new_subscription').submit (e) ->
$('input[type=submit]').attr('disabled', true)
subscription.processCard()
return false
processCard: ->
card =
number: $('#card_number').val()
cvc: $('#card_code').val()
expMonth: $('#card_month').val()
expYear: $('#card_year').val()
Stripe.createToken(card, subscription.handleStripeResponse)
handleStripeResponse: (status, response) ->
if status == 200
$('#subscription_stripe_card_token').val(response.id)
$('#new_subscription')[0].submit()
else
$('#stripe_error').text(response.error.message)
$('input[type=submit]').attr('disabled', false)
false
正如您所看到的，当用户按下
submit$('#new_subscription').submit (e)在我的情况下，有时不会引发提交函数，因此空的
stripe_card_toke奇怪的行为是由 Rails Turbolinks 设施引起的。
我是这样解决的：
gem 'jquery-turbolinks'//= require jquery.turbolinks//= require jquery //= require jquery.turbolinks //= require jquery_ujs //= require turbolinks //= require bootstrap //= require jquery_nested_form //= require_tree .
