Question

Problem: I get an incoming HTTP request to my server application. The request is something like this : http://example.com?id=abc. I need to parse this request, patch additional URL parameters and call a hosted html file. So:

http://example.com?id=abc => http://example.com:8080/temp.html?id=abc&name=cdf.

So the client should see temp.html

Here’s the code:

function onRequest(request,response) {
if(request.method =='GET') {
        sys.debug("in get");
        var pathName = url.parse(request.url).pathname;
        sys.debug("Get PathName" + pathName + ":" + request.url);
        var myidArr = request.url.split("=");
        var myid = myidArr[1];
        //Call the redirect function
        redirectUrl(myid);
}
http.createServer(onRequest).listen(8888);

function redirectUrl(myid) {
var temp='';
    var options = {
      host: 'localhost',
      port: 8080,
      path: '/temp.html?id=' + myid + '&name=cdf',
      method: 'GET'
    };
  var req = http.request(options, function(res) {
    console.log('STATUS: ' + res.statusCode);
    console.log('HEADERS: ' + JSON.stringify(res.headers));
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
      temp = temp.concat(chunk);
    });
    res.on('end', function(){
        return temp;
      });
    });
  req.end();
  return temp;
}

Even though this is a really stupid way of going about this issue, I do see the response in the res.end() callback. How to propagate this to the parent calling function onRequest ?

Is there a simpler way of doing this just using node ? I know that there are ways to serve static html files. However, I need to pass URL parameters to temp.html – so I’m not sure how to do this.

Just wondering if a simpler redirect would serve the purpose:

  function onRequest(request,response) {
    if(request.method =='GET') {
       sys.debug("in get");
       var pathName = url.parse(request.url).pathname;
       sys.debug("Get PathName" + pathName + ":" + request.url);
       var myidArr = request.url.split("=");
       var myid = myidArr[1];
       var path = 'http://localhost:8080/temp.html?id=' + myid + '&name=cdf';
       response.writeHead(302, {'Location': path});
       response.end();
    }
