【问题描述】：
当我尝试向 stripe 发送付款时，我收到一条错误消息：“无效的卡对象：必须是字典或非空字符串。”
付款金额为 5 欧元。我正在使用信用卡号 4242 4242 4242 4242 来测试付款。我可以看到除了“stripe_id”之外，条纹的“Post”参数都是正确的。我一直在尝试查看“stripe_id”有什么问题，但我不知所措。
谁能帮我找出我的代码有什么问题？

这里是 stripe.js：
$(function(){
$("#payment-form").submit(function() {
console.log("#payment-form");
var form = this;
var card = {
number: $("#id_credit_card_number").val(),
expMonth: $("#id_expiry_month").val(),
expYear: $("#id_expiry_year").val(),
cvc: $("#id_cvv").val()
};
Stripe.createToken(card, function(status, response) {
console.log("#createToken");
if (status === 200) {
$("#credit-card-errors").hide();
$("#id_stripe_id").val(response.id);
// Prevent the credit card details from being submitted
// to our server
$("#id_credit_card_number").removeAttr('name');
$("#id_cvv").removeAttr('name');
$("#id_expiry_month").removeAttr('name');
$("#id_expiry_year").removeAttr('name');
form.submit();
} else {
$("#stripe-error-message").text(response.error.message);
$("#credit-card-errors").show();
$("#validate_card_btn").attr("disabled", false);
}
});
return false;
});
});
