how do I pass multiple parameters from jshelper to apex controller in lightning

Question

I would like to pass two strings to my apex controller, but I keep getting an illegal argument error in my debugger.

jshelper-

    var toDate = cmp.get("v.toDate");
    var dateStr = toDate.toString();
    console.log('date string is', dateStr);
    var addTime = cmp.get("v.statNum");
    console.log('passing time = ', addTime);
    var action = cmp.get("c.getDate");
    action.setParams({"addDate" : dateStr, "addTime" : addTime});

apex controller-

    @AuraEnabled
public static Date getDate(string addDate, string addTime){
    system.debug(addTime);
    system.debug(addDate);

Answer 1

ok so this is actually the correct way to pass two arguments from helper to apex. the issue was that I had to convert my addTime to a string (even though in my component it was of type String). working code below

js-

    var toDate = cmp.get("v.toDate");
    var dateStr = toDate.toString();
    var addTime = cmp.get("v.statNum");
    var addTimeStr = addTime.toString();
    var action = cmp.get("c.getDate");
    action.setParams({"addDate" : dateStr, "addTime" : addTimeStr}); 

apex

    @AuraEnabled
    public static Date getDate(string addDate, string addTime){
    system.debug(addTime);
    system.debug(addDate);
