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

console.log('node.js application starting again ...');


var svr = http.createServer(function(req, resp) {
    
    var call_1= {
        url: "http://mocktarget.apigee.net/json",
        method: 'GET'
    };

 var call_2= {
        url: "http://mocktarget.apigee.net/json",
        method: 'GET'
    };
    
    


     call_one = function() {
            request(call_1, function(error, response, body) {
                if (!error && response.statusCode === 200) {
                 console.log("success1..."+JSON.stringify(body));
                 var jsonResponse = JSON.parse(body);
                 console.log("firstname1 : "+jsonResponse.firstName);
                call_two("1 call response")


                } else {
                    console.log("failure1...");
                    call_two("")
                }


            });


        };


     call_one();
        
    
     call_two = function(callOneRes) {
         console.log("First call response :"+callOneRes);
            request(call_2, function(error, response, body) {
                if (!error && response.statusCode === 200) {
                 console.log("success..."+JSON.stringify(body));
                 var jsonResponse = JSON.parse(body);
                 console.log("firstname : "+jsonResponse.firstName);


                } else {
                    console.log("failure...");
                }
            });


        };
        
    resp.end('Hello, World!');    
        
});


svr.listen(9000, function() {
    console.log('Node HTTP server is listening');
});
