Rails:从服务器返回条带响应的JSON [英] Rails: Return JSON of Stripe Response from Server

问题描述

我有多个客户端依靠我的服务器来处理Stripe收费请求.处理费用后，我想向我的客户发送回JSON，以表明费用是否已成功创建，如果不是，则说明原因.

I have multiple clients relying on my server that processes Stripe charge requests. When a charge is processed, I want to send my client back JSON of whether the charge was successfully created, and if it wasn't, the reasons why.

可以在此处进行查看.

我的控制器的代码如下:

The code for my controller is the following:

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

我正在尝试使用以下URL调用我的RESTful API:

I am trying to call my RESTful API with the following URL:

curl -XPOST https://murmuring-wave-13313.herokuapp.com/charges.json?stripeToken=tok_*****************&stripeEmail=[e-mail]

我假设我需要访问某些元数据，但是我我不确定该怎么做.

I'm assuming I need to access some of the metadata, but I'm unsure how to.

这将导致500 Response

如何正确构造我的Charges控制器以返回Stripe响应的JSON?

How can I properly structure my Charges controller in order to return JSON of Stripe's response?

推荐答案

所以我在myself自己.我意识到在创建Stripe::Charge对象后，会为其分配一个JSON序列化的Charge对象.

So I'm smacking myself. What I realized was after you make the Stripe::Charge object, a JSON-serialized Charge object is assigned to it.

因此，您可以通过简单地调用charge.attribute_name来访问Charge实例中的所有元数据.例如，如果这是有效费用，则charge.status将返回成功".由于分配给您的费用是JSON，因此如果请求的格式是JSON，则只需返回render charge即可.

Because of this, you can access all the metadata in the Charge instance by simply calling charge.attribute_name. For instance, if it was a valid charge, charge.status would return "succeeded". Because what assigned back to charge is JSON you can simply return render charge if the requested format is JSON.

工作的Charge控制器如下所示:

The working Charge controller looks like the following:

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
