Question

我需要实施Mercado Pago自定义结帐以在我的网站上接收付款。要做到这一点，我需要运行javascript代码来获取card_token_id，如此链接中所述：https://developers.mercadopago.com/documentation/custom-checkout?lang=en_US。

但是我的网站，为了业务限制，需要将这个card_token_id运行到我的班级的Java代码中。我需要将这个javascript代码运行到我的Java类中，得到结果，然后在http POST中使用它。我已经尝试过使用ScriptEngine，但不行。

请参阅下面的完整代码，该代码适用于html。
