Подключиться к Cloudant CouchDB с помощью Node.js?

I am trying to connect to my CouchDB database on Cloudant using Node.js.

This worked on the shell:

    curl https://weng:password@weng.cloudant.com/my_app/_all_docs

But this node.js code didn't work:

    var couchdb = http.createClient(443, 'weng:password@weng.cloudant.com', true);
    var request = couchdb.request('GET', '/my_app/_all_docs', {
        'Host': 'weng.cloudant.com'
    });
    request.end();
    request.on('response', function (response) {
        response.on('data', function (data) {
            util.print(data);
        });
    });

It gave me this data back:

    {"error":"unauthorized","reason":"_reader access is required for this request"}

How do I do to list all my databases with Node.js?
