Question

我有多个客户端依赖我的服务器来处理Stripe充电请求。处理费用后，我想向我的客户发回JSON，说明费用是否已成功创建，如果不是，则说明原因。

我的服务器可以查看here。

我的控制器的代码如下：

class ChargesController < ApplicationController
    protect_from_forgery
    skip_before_action :verify_authenticity_token

    def new
    end

    def create
      # Amount in cents
      @amount = 500

      customer = Stripe::Customer.create(
        :email => params[:stripeEmail],
        :source  => params[:stripeToken]
      )

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

      #*WHAT I TRIED DOING THAT DIDN'T WORK*
      # respond_to do |format|
      #   msg = { :status => "ok", :message => "Success!"}
      #   format.json  { render :json => msg }
      # end

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

我尝试使用以下网址调用我的RESTful API：

curl -XPOST https://murmuring-wave-13313.herokuapp.com/charges.json?stripeToken=tok_*****************&stripeEmail=rsheeler@gmail.com

我假设我需要访问部分metadata，但我不确定如何使用。

这导致500 Response

如何正确构建Charges控制器以返回Stripe响应的JSON？

Answer 1

为什么这不起作用？

#*WHAT I TRIED DOING THAT DIDN'T WORK*
 respond_to do |format|
   msg = { :status => "ok", :message => "Success!"}
   format.json  { render :json => msg } # don't do msg.to_json
   format.html  { render :template => "charges/create"}
 end

您的日志中有哪些错误？

所以我在打自己。我意识到，在您创建Stripe::Charge对象后，会为其分配一个JSON序列化的Charge对象。

因此，您只需拨打Charge即可访问charge.attribute_name实例中的所有元数据。例如，如果它是有效的费用，charge.status将返回“成功”。因为分配回费用的是JSON，如果请求的格式是JSON，您只需返回render charge。

工作充电控制器如下所示：

class ChargesController < ApplicationController
    protect_from_forgery
    skip_before_action :verify_authenticity_token

    def new
    end

    def create
      # Amount in cents
      @amount = 500

      customer = Stripe::Customer.create(
        :email => params[:stripeEmail],
        :source  => params[:stripeToken]
      )

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

      # If in test mode, you can stick this here to inspect `charge` 
      # as long as you've imported byebug in your Gemfile
      byebug

      respond_to do |format|
        format.json  { render :json => charge }
        format.html  { render :template => "charges/create"}
      end

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