Ruby on rails 试图通过自定义表单处理单条付款

我正试图通过一个自定义表单通过Stripe处理付款；但是，我反复遇到一个Stripe:：invalidRequester错误，即您必须提供卡或客户id错误。我在SO上引用了类似的错误消息，但我无法将其应用于我的代码

根据我的日志，我发现问题出在

操作中的

学生

控制器中，但我可以找出如何修复代码。非常感谢您的帮助

学生\u控制器.rb：

class StudentsController < ApplicationController

def index
    @students = Student.all
end

def show
    @student = Student.find(params[:id])
end

def new
    @student = Student.new
end

def create
    @student = Student.create(student_params)
    #@payment = Payment.create

    Stripe.api_key = [STRIPE_KEY]

    token = params[:stripeToken]

    begin

      charge = Stripe::Charge.create( 
        amount:      total(@student),
        currency:    "usd",
        card:        token,
        description: student_params[:email]  
      )

      redirect_to @student, :notice => "Thank you for registering!"

    rescue Stripe::CardError => e
        # The card has been declined or some other error has occured
      @error = e
      render :new
    end
end

事件注册

参数[:stripeToken]应该来自哪里？我在您的表单中没有看到它，通常会有一些（Java | Coffee）脚本将卡的详细信息发送到Stripe并取回令牌。很抱歉，我遗漏了

application.html.erb

layout文件。现在已经添加了。我只是把回调脚本放在这里，我认为这不是问题。您检查了

create

调用的请求日志了吗？它应该告诉您

params

中的真正内容。是的，除了

stripeToken

之外，所有内容都被传递到

params

。这就是让我发疯的原因。Stripe的令牌调用脚本在那里，但我不知道为什么它不起作用。我正在使用更好的错误gem，错误发生在'charge=Stripe:：charge.create（`在我的控制器中。您确定提交的

与您的JavaScript所认为的一样吗？请注意，这里有两个

。
