錯誤類型錯誤：無法復制NilClass-條帶化

Question

我收到一個錯誤ERROR TypeError: can't dup NilClass在處理Strip裝料時ERROR TypeError: can't dup NilClass 。 我遵循了Rails Stripe集成文檔。

來自終端的錯誤是：

Answer 1

從顯示的代碼看來，您可能有幾個問題，但是可能還有其他與Stripe Payment設置有關的問題。

這里介紹了在應用程序中設置Stripe的過程。

在應用程序中設置條帶

將Stripe鍵添加到config/secrets.yml文件：

development:
  stripe_private_key: <%= ENV["STRIPE_PRIVATE_KEY"] %>
  stripe_public_key: <%= ENV["STRIPE_PUBLIC_KEY"] %>

您可以將STRIPE_PRIVATE_KEY和STRIPE_PUBLIC_KEY保留在您的環境中。 測試和生產環境將需要類似的配置設置。

確保將此代碼添加到您的控制器或您打算使用Stripe API的任何代碼中：

require "stripe"
Stripe.api_key = Rails.application.secrets.stripe_private_key

添加遷移以將Stripe客戶ID添加到客戶

此遷移提供了一個基於User類的示例； 您的應用程序可能使用其他模型，因此請根據需要進行調整。

class AddUserStripeCustomerId < ActiveRecord::Migration
  def change
    change_table :users do |t|
      t.string :stripe_customer_id, limit: 50, null: true
    end
  end
end

創建客戶

准備好開始為客戶開票時，請創建客戶：

if !@user.stripe_customer_id
  customer = Stripe::Customer.create(
    :email => stripe_details[:stripeEmail],
    :source  => stripe_details[:stripeToken]
  )

  User.update(stripe_customer_id: customer)
end

確保在用戶模型中保存客戶ID。 您需要注意不要為該用戶重新創建和覆蓋您的客戶ID，因為這是該用戶與Stripe付款系統的結合。

實施控制器

您提交的表單元素（參數）的作用域不像基於Rails模型的表單那樣。 通常，這是由於對不直接基於模型的表單使用了form_tag 。 這意味着對參數進行范圍限定，而不是使參數受模型哈希限制。

您的強參數不在此處，但它們可能是問題的一部分。 確保permit列表中包含stripeToken和stripeEmail ，如下所示：

params.permit(:stripeToken, :stripeCard, :stripeEmail)

確保在強參數上不包括典型的require方法，因為這可以驗證參數是否受模型對象限制。 在您的create方法中，應該調用強參數方法，並使用結果，如下所示：

require "stripe"

class ChargesController < ApplicationController
  Stripe.api_key = Rails.application.secrets.stripe_private_key

  def new
  end

  def create
    # Amount in cents
    @amount = 500

    stripe_details = stripe_params

    if !@user.stripe_customer_id
      customer = Stripe::Customer.create(
        :email => stripe_details[:stripeEmail],
        :source  => stripe_details[:stripeToken]
      )

      User.update(stripe_customer_id: customer)
    end

    charge = Stripe::Charge.create(
      :customer    => customer.id,
      :amount      => @amount,
      :description => 'Rails Stripe customer',
      :currency    => 'usd'
    )

  rescue Stripe::CardError => e
    flash[:error] = e.message
    redirect_to new_charge_path
  end

private
  def stripe_params
