Estoy tratando de obtener una autenticación de resumen simple (!) Que funcione con el nodo js utilizando una API de gathercontent.com.

Todo parece estar funcionando, excepto que todavía recibo una respuesta de "Credenciales erróneas" que se ve así:

{ success: false, error: 'Wrong Credentials!' }

El código se ve así:

var https = require('https'),
    qs = require('querystring');
apikey = "[my api key goes in here]",
    pwd = "[my password goes in here]",
    crypto = require('crypto');


module.exports.apiCall = function () {

    var options = {
        host:'abcdefg.gathercontent.com',
        port:443,
        path:'/api/0.1/get_pages_by_project/get_me',
        method:'POST',
        headers:{
            "Accept":"application/json",
            "Content-Type":"application/x-www-form-urlencoded"
        }
    };

    var req = https.request(options, function (res) {

        res.on('data', function (d) {
            var creds = JSON.parse(d);


            var parsedDigest = parseDigest(res.headers['www-authenticate']);
            console.log(parsedDigest);
            var authopts = {
                host:'furthercreative.gathercontent.com',
                port:443,
                path:'/api/0.1/get_pages_by_project/get_me',
                method:'POST',
                headers:{
                    "Accept":"application/json",
                    "Content-Type":"application/x-www-form-urlencoded",
                    "Authorization" : getAuthHeader(parsedDigest, apikey, parsedDigest['Digest realm'], pwd)
                }
            };

            console.log(authopts);
            console.log('\n\n\n');
            var req2 = https.request(authopts, function (res2) {
                console.log("statusCode: ", res2.statusCode);
                console.log("headers: ", res2.headers);


                res2.on('data', function (d2) {
                    var result = JSON.parse(d2);

                });
            });

            req2.end();



        });

    });


    req.write('id=1234');

    req.end();

    req.on('error', function (e) {
        console.error(e);
    });

};

function parseDigest(s){

    var parts = s.split(',');
    var obj = {};
    var nvp = '';

    for(var i = 0; i < parts.length; i++){

        nvp = parts[i].split('=');
        obj[nvp[0]] = nvp[1].replace(/"/gi, '');
    }



    return obj;
}

function getAuthHeader(digest, apikey, realm, pwd){
    var md5 = crypto.createHash('md5');
    var s = '';

    var nc = '00000001';
    var cn = '0a4f113b';

    var HA1in = apikey+':'+realm+':'+pwd;
    md5 = crypto.createHash('md5');
    md5.update(HA1in);
    var HA1out = md5.digest('hex');

    var HA2in = 'POST:/api/0.1/get_pages_by_project/get_me';
    md5 = crypto.createHash('md5');
    md5.update(HA2in);
    var HA2out = md5.digest('hex');

    md5 = crypto.createHash('md5');
    var respIn = HA1out + ':' + digest.nonce + ':'+nc+':'+cn+':'+digest.qop+':'+ HA2out;
    md5.update(respIn);
    var resp = md5.digest('hex');


    s = [   'Digest username="',apikey,'", ',
        'realm="',digest['Digest realm'],'", ',
        'nonce="',digest.nonce,'", ',
        'uri="/api/0.1/get_pages_by_project/get_me", ',
        'cnonce="',cn,'", ',
        'nc="',nc,'", ',
        'qop="',digest.qop,'", ',
        'response="',resp,'", ',
        'opaque="',digest.opaque,'"'].join('')

    return s;
}

Lo intentaría y Curl pero no estoy seguro de cómo!

Cualquier ayuda apreciada!
