如何通过JSON处理查询数据？

Question

我正在使用第三方API（到目前为止，还不错，我得到了结果），但是由于我是新手，所以很难为前端（EJS）操纵这些结果** ... < / p>

系统应该做的是：

该站点是一个图形面板，我在其中使用第三方API（如果由前端使用，它将阻止源），并使用名为（CHARTJS）的图形插件填充JSON中接收的数据。在那里，因为应该在访问页面后立即使用API​​，并在使用后填充图形，但是对于我来说，要使用此JSON，我需要传递一些QS ...访问第一个图形的页面时这些QS是已经是自动的，并且可以由包含相同页面的表单来操纵，以便能够执行其他查询..

我完全迷失了，我希望得到一些帮助和解释..

CONTROLLERS / LOGIN / LOGIN.JS

module.exports.index = (_application, _request, _response) => {
    _response.render('login/index');
}

module.exports.check_login =  (_application, _request, _response) => {
    const JSON_MODEL = new _application.app.models.jsonDAO('fatVenda.xsjs', '\'BSC\'', '201807', 'vendaabs,vendam2');
    JSON_MODEL.request();

    console.log(JSON_MODEL.jsonData)

    const VENDA_MODEL = new _application.app.models.vendaDAO('', '', '', '');

    _response.render('home/home');
