title: Nodejs http request not working
body: <p>I have a piece of code that's supposed to do a http get request. The program exited successfully without error, but I didn't see any response and it didn't even go inside the callback function! At first I thought it's because http is asynchronous and put a large loop in the end but that didn't work either. Does anyone know this issue? Only the first console log sendHttpRequest and 444 gets printed. I also tried the http.get but it didn't work either.</p>
  
  <pre><code>function sendHttpRequest (url, callBack) {
      console.log("sendHttpRequest");
      //constrct options
      var options = {
          host: 'www.google.com',
          path: '/index.html',
          method: 'GET',
          headers: {
             'Content-Type': 'application/x-www-form-urlencoded'
          }
      };
  
      http.get("http://www.google.com/index.html", function(res) {
          console.log("Got response: " + res.statusCode);
      });
  
      var req = http.request(options, function(res) {
          console.log("333");
          var output = '';
          console.log(options.host + ':' + res.statusCode);
          res.setEncoding('utf8');
  
          res.on('data', function (chunk) {
              console.log("DATATATAT!")
              output += chunk;
          });
  
          res.on('end', function () {
              console.log('222');
              var obj = JSON.parse(output);
              callBack(res.statusCode, obj);
          });
      });
  
      req.on('error', function (err) {
          console.log('error: ' + err.message);
      });
  
      req.end();
      console.log("444");
      }
  }
