【问题描述】：

在我的应用中，我使用“Stripe” gem 来设置付款。一切都很好，但是每当我提交付款时，它都会给我一个错误“您必须提供有效的卡”。 下面是我的代码。

广告控制器

class AdsController < ApplicationController
  before_action :set_ad, only: [:show, :edit, :update, :destroy]


  # GET /ads
  # GET /ads.json
  def index
    @ads = Ad.order('created_at DESC').search(params[:search])
    @ads_small = Ad.where(:size => "small").order('created_at DESC')
    @ads_medium = Ad.where(:size => "medium").order('created_at DESC')
    @ads_featured = Ad.where(:size => "featured").order('created_at DESC')

  end

  def myads
    @ads_mine = Ad.where(:user_id => current_user.id )
  end

  # GET /ads/1
  # GET /ads/1.json
  def show
  end

  # GET /ads/new
  def new
    @ad = Ad.new
  end

  # GET /ads/1/edit
  def edit
  end

  # POST /ads
  # POST /ads.json
  def create
    @ad = Ad.new(ad_params)
    @ad.user_id = current_user.id

    respond_to do |format|
      if @ad.save_with_payment
        format.html  redirect_to @ad, notice: 'Ad was successfully created.' 
        format.json  render action: 'show', status: :created, location: @ad 
      else
        format.html  render action: 'new' 
        format.json  render json: @ad.errors, status: :unprocessable_entity 
      end
    end
  end

  # PATCH/PUT /ads/1
  # PATCH/PUT /ads/1.json
  def update
    respond_to do |format|
      if @ad.update(ad_params)
        format.html  redirect_to @ad, notice: 'Ad was successfully updated.' 
        format.json  head :no_content 
      else
        format.html  render action: 'edit' 
        format.json  render json: @ad.errors, status: :unprocessable_entity 
      end
    end
  end

  # DELETE /ads/1
  # DELETE /ads/1.json
  def destroy
      @ad.destroy
      respond_to do |format|
        format.html  redirect_to ads_url 
        format.json  head :no_content 
      end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_ad
      @ad = Ad.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def ad_params
      params.require(:ad).permit(:title, :url, :preview, :location, :size, :info, :search)
    end
end

广告模型

class Ad < ActiveRecord::Base

    belongs_to :user
  has_attached_file :preview, :styles =>  :medium => "125x125^", :featured => "250x250^", :showpg => "400x400^" , :convert_options => :medium => "-gravity center -extent 125x125", :featured => "-gravity center -extent 250x250", :showpg => "-gravity center -extent 400x400"

  validates :title, length:  maximum: 35 
  validates :url, length:  maximum: 40 

  attr_accessor :stripe_card_token

  def self.search(search)
  if search
    find(:all, :conditions => ['LOWER(title) ILIKE ? or LOWER(info) ILIKE ? or LOWER(location) ILIKE ?', ("%#search.downcase%"), ("%#search.downcase%"), ("%#search.downcase%")])
  else
    find(:all)
  end
  end

  def save_with_payment
    if valid?
      customer = Stripe::Customer.create(description: "ad stripe customer", plan: "ad_f", card: stripe_card_token)
      self.stripe_customer_token = customer.id
      save!
    end
  end
end

ads.js.coffee

# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://coffeescript.org/

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

 ad = 
    setupForm: ->
        $('#new_ad').submit ->
            $('input[type=submit]').attr('disabled', true)
            ad.processCard()
            false

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

  handleStripeResponse: (status, response) ->
    if status == 200
        $('#ad_stripe_card_token').val(response.id)
        $('#new_ad')[0].submit()
    else
        alert(response.error.message)
        $('input[type=submit]').attr('disabled', false)

任何帮助将不胜感激。 :)

【问题讨论】：

是的，它们只是复制 n 粘贴错误，但我已经将它们整理出来了 :)

这是直播还是测试？在测试中..我认为唯一有效的是 4242424242424242 作为卡号...

【参考方案1】：

在您的 Ad 模型中，您有：

attr_accessor :stripe_card_token

然后你使用save_with_payment中的令牌：

customer = Stripe::Customer.create(..., card: stripe_card_token)
self.stripe_customer_token = customer.id

到目前为止一切顺利。但是当您创建Ad 时，您使用ad_params 在控制器中过滤params：

def ad_params
  params.require(:ad).permit(:title, :url, :preview, :location, :size, :info, :search)
end

我在任何地方的允许列表中都看不到:stripe_card_token。大概您的 HTML 中的 #ad_stripe_card_token 如下所示：

<input type="hidden" name="ad[stripe_card_token]">

所以您应该能够将:stripe_card_token 添加到ad_params 中的允许列表中并让事情顺利进行。

对不起，我没有注意到这个答案我最终还是想通了，但我仍然会投票赞成你的答案。
