how to get the complete response of a request and return to another function?

what i mean is : i want to get complete request from a treehouse api and pass it to another function by using node js , but when i tried this :

var http = require('http');
var https = require('https');
var body = '';
var request = http.createServer(function(request,response){
    response.writeHead({'content-Type':'text/plain'});
    response.write("##########################################################################");
    var req = https.get("https://teamtreehouse.com/joshtimonen.json",function(resp){
        resp.on('data',function(chunk){
            body+= chunk;
        });
        resp.on('end',function(){
            >>>>>>>>>>>>>line of problem//response.write("Name"+resp.finished+resp.statusCode+JSON.parse(body).name);
            return body;
            response.end("###########################################################################");
        });
    });
    response.end(req);

}).listen(3000);
request.on('error',function(error){
    console.log('server is getting error :: '+error.message);
});

in the line of problem marked as >>>> i am getting error because complete response not being recieved before ending write..

var http = require('http');
var https = require('https');

var httpServer = http.createServer(function(serverReq, serverRes) {
    var body = '';

    var req = https.get("https://teamtreehouse.com/joshtimonen.json", function(res) {
        res.on('data', function(data) {
            body += data;
        });
        res.on('end', function() {
            serverRes.writeHead(200, {'Content-Type': 'text/plain'});
            serverRes.end(body);
        });
    });
    req.end();
});

httpServer.listen(3000, function() {
    console.log('Server is running!');
});

httpServer.on('error', function(err) {
    throw err;
});

You want to send your data when you recieved it all, so inside the res.on('end') you close the response to your server with the content you want to respond with.

Thanks Jesus but i wanted to use the response to getname, total aand other things separately like : var http = require('http'); var https = require('https'); var body = '';

var httpServer = http.createServer(function(serverReq, serverRes) {

var req = https.get("https://teamtreehouse.com/joshtimonen.json", function(res) {
    res.on('data', function(data) {
        body += data;
    });
    res.on('end', function() {
        serverRes.writeHead(200, {'Content-Type': 'text/plain'});
        serverRes.end(body);
    });
});
getName(body);
req.end();

});

httpServer.listen(3000, function() { console.log('Server is running!'); });

httpServer.on('error', function(err) { throw err; }); var getName = function(body){ console.log(body.Name+"\n"); }

but i am getting "undefined" in the console of getName method.
