Question

I’ve got the following code, but it doesn’t seem to work:

var post_req = {
    array: [
        [ {
            param1: 'something',
            param2: 123
        } ],
        [ ],
        [ ],
        [ {
            param2: 'something',
            param4: 1234,
            param1: 'hello'
        } ]
    ]
};
var data_send = querystring.stringify(post_req);

var request = client.request('POST', '/', headers);
request.end(data_send);

and

if( req.method == 'POST' ) {
    req.addListener('data', function(chunk)
    {
        POST = querystring.parse(chunk);
        console.log(POST);
    }
}

I end up with 5 sub-arrays, corresponding to the 5 parameters in the objects but with extra ‘][‘ characters in their names:

{ array: 
   [ { '][param1': 'something' }
   , { '][param2': '123' }
   , { '][param2': 'something' }
   , { '][param4': '1234' }
   , { '][param1': 'hello' }
   ]
}

There is a new node package that fixes this: “npm install qs”.

https://github.com/ljharb/qs

“query string parser for node supporting nesting, as it was removed from 0.3.x, so this library provides the previous and commonly desired behaviour (and twice as fast)”

If anyone can tell me why it was removed from 0.3.x, I will give you an upvote for your comment. (I want my confidence in Node.js restored.)
