Question

我正在使用cryptocompare API在 POSTMAN 中将货币转换为EUR，我有包含128个国家/地区货币的json数据。我想将任何货币转换为 EUR 并在用户以fsyms（来自符号）输入货币时获得PRICE，它可以将其转换为EUR。当我阅读用户可以输入的fsyms时，我将此值存储在一个名为userinput的变量中，问题是当我在 jsonData.DISPLAY.userinput.EUR.PRICE 之间传递此变量时，它无法工作并且在邮递员控制台中显示错误 TypeError：无法读取未定义的属性“ EUR” 。

邮递员测试

var jsonData = JSON.parse(responseBody);
const paramsString = request.url.split('?')[1];
const eachParamArray = paramsString.split('&');
let params = {};
eachParamArray.forEach((param) => {
    const key = param.split('=')[0];
    const value = param.split('=')[1];
    Object.assign(params, {[key]: value});
});
var userinput = (params.fsyms);// this is object with request params as key value pairs
var data = jsonData.DISPLAY.userinput.EUR.PRICE;
console.log(userinput);
