google - Intentando importar contactos de gmail usando node.js

node js gmail api

Question

Estoy tratando de importar contactos de Gmail. He obtenido con éxito el access_token, pero al intentar obtener el navegador de contactos sigue arrojando el error. invalid_grant

mis códigos a continuación.

para autenticación y devolución de llamada.

    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();
    }
    });

  },

para importar contactos

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);
  });

}

Realmente aprecio ayuda.

En su función getContactsFromGoogleApi cambie el encabezado Authorization a lo siguiente;

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

El siguiente es el código en C # para hacer lo mismo

        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);

La URL que utilicé aquí es la misma que tu código; http://www.google.com/m8/feeds/

Cuando hice esto en C #, no tuve que pasar la versión.
