standard technique for getting post parameters?

[Jason Wang]

Hi all,

I was just wondering whether there are any standard techniques for
getting post parameters from the body. Here is something i copied from
nodewiki:

function getPostParams(req, callback){
var body = '';
sys.puts('in here');
req.addListener('body', function(chunk){body += chunk;})
.addListener('complete', function(){
callback(unescape(body.substring(8).replace(/\+/g,' ')));
});
}

It doesn't seem to work, and the process just hangs (in the callback,
i just did sys.puts('done'); sys.puts(content); where content is the
sole parameter for the callback. Only 'done' gets printed).

Is there any better way of doing it?

Any enlightenment would be much appreciated!

  var body = "";
 
  // build the full request body
  req.addListener("body", function(chunk) {
        body+=chunk;
  });
 
  req.addListener("complete", function() {
       // body is the full request body
  });


Hope it helps!

Well, it turned out my code works (thank you Elljah for confirming
that the problem is somewhere else!). I didn't get anything is because
i did not put a name attribute to my form elements. Stupid me, thanks
a lot!
