making multiple api endpoint calls from array nodejs

I'm having trouble making calls to API endpoints from an array. The array contains values that I need to feed into the endpoint in order to get data that I need. The trouble I am having is when I console log the data from the api call I receive JSON text. However, when I try to parse the text and get a specific value from the JSON text it is not giving me the results. Here is the code I am working on:

var http = require("http");
var areaCodes = ["'0071950')", "'0072850')", "'0073450')", "'0075700')", "'0076450')", "'0078700')", "'0900001')", "'0900000')"];
var results = [];
var encode = [];

    //source: http://stackoverflow.com/questions/17811827/get-a-json-via-http-request-in-nodej
for(var i = 0; i < areaCodes.length; i++){
    var realmStatus = "http://api.dol.gov/V1/Statistics/OES/OE_SERIES/?KEY=XXXXXXXXXXXXXXXXXXXXXXXXXX&$filter=(OCCUPATION_CODE eq '151131' ) and (AREA_CODE eq " + areaCodes[i];
     encode.push(encodeURI(realmStatus));

var options = {
        host: 'api.dol.gov',
        path: encode[i],
        type: 'GET',
        dataType: 'json',
        headers: {'accept' : 'application/json'}
};
console.log("Start");
var x = http.request(options,function(res){
    console.log("Connected");
     var str = '';
    res.on('data', function(chunk) {
        str += chunk;
    });
    res.on('data',function(data){
        if(res.statusCode == 200){
            //console.log("res status is good");
            try{
                 var dataA = JSON.parse(str);
                //run a for loop 
                for(var h = 0; h < dataA.d.results.length; h++){
                    var seriesNum = dataA.d.results[h].SERIES_ID; 
                    array.push(seriesNum);
                    console.log(seriesNum);
                }
                 //end for
            }catch(e){
                console.log('Error parsing JSON');
            }
        }
    });
});
x.end();
}//end for loop

I'd appreciate if someone would be willing to explain if there is anything I did incorrectly, or if there is something I am missing. Thanks!
