An esay way to accept GET or POST variables on a node.js server is the sample show below:

var fu = require("./fu"),
sys = require("util"),
url = require("url"),
qs = require("querystring");
var nodemailer = require('nodemailer');

fu.get("/entrar", function (req, res) {
   // ------ condition to chech if call are POST o GET
   if(req.method=="POST") {
      var body="";
      req.on("data", function (data) {
        body +=data;
      });
      req.on("end",function(){
         var variables =  qs.parse(body);
         var pathname = url.parse(req.url).pathname;
         //rest of code - this function is executed when all the variables are received

      });
      req.on("error",function(e){
         //console.log('problem with request: ' + e.message);
      });
   }
   else if(req.method=="GET") {
      var variables = url.parse(req.url, true).query;
      var pathname = url.parse(req.url).pathname;
      //rest of code - We have no wait variables like POST request
   }

   // end condition post o get
   return ;//"ok:
});

In this case this funcion works with POST and GEt request, on the GET request case, there is no problem to get the variables with the function: url.parse(req.url, true).query;

as you can see, the trick in a POST request is  the instruction: req.on( when the variables “POST” are fully recived , then req.on(“end”,function(){}) are executed.

remember that node.js is an asyncronous envirovment and the function req.on is executed after main function end.
