Javascript jQuery.post返回400错误请求错误[rails]

我正在使用rails 4和balanced.js，并试图使用jQuery.post将返回的令牌发布到后端。我通过了正确的url，但收到400错误。澄清一下：在收到来自balanced的有效令牌后，我在jquery.ajax上遇到了一个错误

jQuery ->
$('#cc-submit').click (e) ->
    e.preventDefault()

    handleResponse = (response) ->
        if (response.status_code == 201)

            fundingInstrument = (if response.cards? then response.cards[0] else response.bank_accounts[0])

            alert(fundingInstrument.href)

            $('#tablecharge_uri').val(fundingInstrument.href)

            url = '/events/' + urlid + '/tablecharges'

            alert(url)

            jQuery.ajax({type: "POST", url: url, data: {uri: fundingInstrument.href, event_id: urlid}, sucess: (data) ->
                alert data.id
            error: (data) ->
                alert "not cool"})

        else
            alert(response.status + JSON.stringify(response, false, 1))

    payload = {
    name: $('#cc-name').val()
    number: $('#cc-number').val()
    expiration_month: $('#cc-expiration-month').val()
    expiration_year: $('#cc-expiration-year').val()
    ccv: $('#cc-ccv').val()
    }

    balanced.card.create(payload, handleResponse)

这是我的控制器：

class TablechargesController < ApplicationController
def new
    @event = Event.find(params[:event_id])
    @table = @event.tablecharges.build
end

def index
    @event = Event.find(params[:event_id])
    @table = @event.tablecharges.all
end

def create
    @event = Event.find(params[:event_id])
    @table = @event.tablecharges.build(table_charge_params)
    respond_to do |format|
        format.js { render json: 'Your message', status: :ok } 
    end
    if @table.save
        redirect_to @event, :notice => "Thanks for the cash"
    else
        render :new
    end
end

private

def table_charge_params
    params.require(:tablecharge).permit(:name, :email)
end

更新2： 下面是来自rails服务器的错误

 ActionController::ParameterMissing - param is missing or the value is empty
 actionpack (4.1.4) lib/action_controller/metal/strong_parameters.rb:183:in `require'

您的数据有效负载缺少键“table_charge”

require在这里是非常描述性的，如果没有键，它就会爆炸

您收到的400错误的文本是什么？POST 400（错误请求）全文是什么？来自Balanced的400个错误正好表明请求中的格式错误。哦，问题出在jQuery.ajax中，而不是balance.card.create中。balanced.js给了我正确的令牌，我只是无法将其发布到后端？@adminbanks In

url='/events/'+urlid+'/tablecharges'

我看不到您的函数中定义了urlid
