Tentativo di importare contatti gmail tramite node.js

Question

Sto cercando di importare i contatti di Gmail. Ho ottenuto con successo access_token ma quando provo ad ottenere il browser dei contatti continua a lanciare l'errore. invalid_grant

i miei codici di seguito.

per l'autenticazione e la richiamata.

authorize: function(req, res){ 
    var CLIENT_ID = '927112080821-vhsphqc79tb5ohfgpuvrp8uhh357mhad.apps.googleusercontent.com'; 
    var CLIENT_SECRET = 'gdgofL0RfAXX0in5JEiQiPW8'; 
    var SCOPE = 'https://www.google.com/m8/feeds'; 
     oa = new oauth.OAuth2(CLIENT_ID, 
       CLIENT_SECRET, 
       "https://accounts.google.com/o", 
       "/oauth2/auth", 
       "/oauth2/token"); 
    res.redirect(oa.getAuthorizeUrl({scope:SCOPE, response_type:'code', redirect_uri:'http://localhost:1234/callback'})); 
    }, 
    callback: function(req, res){ 
    console.log(req.query.code); 
    oa.getOAuthAccessToken(req.query.code, {grant_type:'authorization_code', redirect_uri:'http://localhost:1234/callback'}, function(err, access_token, refresh_token) { 
    if (err) { 
     res.end('error: ' + JSON.stringify(err)); 
    } else { 
      getContactsFromGoogleApi(access_token); 

     //res.write('access token: ' + access_token + '\n'); 
     //res.write('refresh token: ' + refresh_token); 
     //res.end(); 
    } 
    }); 

    }, 

per l'importazione dei contatti

function getContactsFromGoogleApi (access_token, req, res, next) { 
console.log('access_token ' + access_token); 
request.get({ 
    url: 'https://www.google.com/m8/feeds/contacts/default/full', 
    qs: { 
     alt:   'json', 
     'max-results': 1000, 
     'orderby':  'lastmodified' 
    }, 
    headers: { 
     'Authorization': 'OAuth ' + access_token, 
     'GData-Version': '3.0' 
    } 
    }, function (err, res, body) { 
    if(res.statusCode === 401){ 
     return res.redirect('index'); 
    } 
    var feed = JSON.parse(body); 

    var users = feed.feed.entry.map(function (c) { 
     var r = {}; 
     if(c['gd$name'] && ['gd$fullName']){ 
     r.name = c['gd$name']['gd$fullName']['$t']; 
     } 
     if (c['gd$email'] && c['gd$email'].length > 0) { 
     r.email = c['gd$email'][0]['address']; 
     r.nickname = r.email;//c['gd$email'][0]['address'].split('@')[0]; 
     } 
     if(c['link']){ 
     var photoLink = c['link'].filter(function (link) { 
      return link.rel == 'http://schemas.google.com/contacts/2008/rel#photo' && 
       'gd$etag' in link; 
     })[0]; 
     if(photoLink) { 
      r.picture = '/users/photo?l=' + encodeURIComponent(photoLink.href); 
     } else if (r.email) { 
      r.picture = gravatar.url(r.email, { 
      s: 40, 
      d: "https://ssl.gstatic.com/s2/profiles/images/silhouette80.png"}); 
     } 
     } 
     return r; 
    }).filter(function (u) { 
     return !!u.email &&     //we can only give access to persons with email at this point 
      !~u.email.indexOf('@reply.'); //adress with @reply. are usually temporary reply address for forum kind of websites. 
    }); 

    res.json(users); 
    }); 

}

apprezzare veramente di aiuto.

Nella funzione getContactsFromGoogleApi modificare l'intestazione Autorizzazione come segue;

headers: { 
     'Authorization': 'Bearer ' + access_token, 
     'GData-Version': '3.0' 

Quello che segue è il codice in C# per fare la stessa cosa

 webClient = new WebClient(); 
     webClient.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)"); 
     webClient.Headers.Add(HttpRequestHeader.Authorization, String.Format("Bearer {0}", AccessToken)); 

     do 
     { 

      contactStream = webClient.DownloadData(String.Format("{0}?start-index={1}", BaseApiEndpoints[Applications.Contacts], startIndex)); 

      contactDocument = System.Text.Encoding.Default.GetString(contactStream); 

      contacts = new XmlDocument(); 
      contacts.LoadXml(contactDocument); 


      // TODO: use xsl to convert results to ContactSearchResults 
      xslt    = new XslCompiledTransform(); 
      resultStream  = new MemoryStream(); 
      writer   = new XmlTextWriter(resultStream, Encoding.ASCII); 
      translateContact = new XmlDocument(); 

      xslStream  = GetRequest("GoogleContacts.xslt"); 
      xslStream.Seek(0, SeekOrigin.Begin); 
      templateReader = XmlReader.Create(xslStream); 
      xslt.Load(templateReader); 

      xslt.Transform(contacts,writer); 
      resultStream.Seek(0, SeekOrigin.Begin); 

      TranslatedContacts = ConvertByteArrayToString(ReadFully(resultStream)); 

      csr = (ContactSearchResults)Deserialize(typeof(ContactSearchResults), TranslatedContacts); 

      foreach (Contact contact in csr.Contacts) 
      { 
       contact.RecordId = Guid.NewGuid(); 
       // now we want to get the image 
       contact.Picture = GetImage(contact.PictureUrl, AccessToken); 


       if ((!String.IsNullOrEmpty(contact.Name)) || (!String.IsNullOrEmpty(contact.Email))) 
        results.Add(contact); 

      } 

      startIndex += csr.ItemsPerPage; 

     } while (startIndex < totalResults); 

URL ho usato qui è lo stesso come il tuo codice; http://www.google.com/m8/feeds/

Quando ho fatto questo in C# non ho avuto bisogno di passare la versione.
