Question

我正在尝试创建一个模型抵押贷款功能来学习API.ai webhooks，它正在调用一个计算每月抵押贷款支付的函数。由于某种原因，这不会向API.ai发送任何内容，并在JSON中显示错误消息“Webhook调用失败。错误：500内部服务器错误”。（我知道代码效率低下，但一旦工作，我就会清理它）

这里叫它：

var bankNames = assistant.getArgument('bankName');
        var arrayLength = bankNames.length;

        var avgYearPercent = getRandomDouble(2.5,4.2);
        var monthsLeft = 12;
        var loanAmount = getRandomInt(100000,300000);
        var output = '';

        for (var i = 0; i < arrayLength; i++) 
        {   //calcMonthlyPayments(avgPercent, monthsLeft, loanAmount)
            var speech = bankNames[i] + " has an outstanding loan of " + loanAmount + " and your monthly payment is currently " + String(calcMonthlyPayments(avgPercent, monthsLeft, loanAmount));
            output = output.concat(speech);

            }
        output = '<speak>' + output + '</speak>';
        assistant.ask(output);

这就是功能：

function calcMonthlyPayments(avgYearPercent, monthsLeft, loanAmount)
{
    var i = (avgYearPercent/12)/100;
    var r = 1/(1+i);        
    var L = loanAmount;         
    var n = monthsLeft; 
    var P = (L*((1-r)/(r-(Math.pow(r, n+1))))).toFixed(2);

    return P;   
}

混淆javascript函数？
