Access to req, res objects

[samuelbodin]

From the examples it's not entirely clear to me how I can access data that I pass to the bindEmitter() function. In the code below I use the createServer from the http module. Now my question is, how can I save the request and response objects to later access them from my foo function?

var createNamespace = require('continuation-local-storage').createNamespace;
var session  = createNamespace('some namespace');
var http = require('http');

function foo() {
    // How do I access res/req from here?
}

http.createServer(function (req, res) {
  session.bindEmitter(req);
  session.bindEmitter(res);

  // Call foo without passing in req and res.
  foo();
}).listen(8000);

var createNamespace = require('continuation-local-storage').createNamespace;
var session  = createNamespace('some namespace');
var http = require('http');

http.createServer(function (req, res) {
  session.bindEmitter(req);
  session.bindEmitter(res);

  // Call foo without passing in req and res.
  foo();

  function foo() {
      console.log(req, res);
  }
}).listen(8000);

like this?

bindEmitter only ensures continuation through event emitters. It doesn't expose anything to the context.

What you need is to do something like session.set('request', req) and then session.get('request') later.
