credentials.expiry_date problem

[MikeFang]

I am a newer on Node.Js. Could anyone do me a favor? The following code I edited from the example oauth2.js and my environmet is Windows 7. I got the messages from my condole, the major error occurred at the c:\tmp\foo\node_modules\googleapis\lib\auth\oauth2client.js:245

var expiryDate = credentials.expiry_date;
                              ^
TypeError: Cannot read property 'expiry_date' of undefined

Console's log message:

c:\tmp\foo>node index

Code:

app.get('/oauth2callback', function(req, res) {
   var code = req.query.code;
    console.log('code: '+code);
    var CLIENT_ID = 'id here';
    var CLIENT_SECRET = 'secret here';
    var REDIRECT_URL = 'http://localhost:3000/oauth2callback';
    var google = require('googleapis');
    var OAuth2 = google.auth.OAuth2;
    var plus = google.plus('v1');
    var oauth2Client = new OAuth2(CLIENT_ID, CLIENT_SECRET, REDIRECT_URL);

// retrieve an access token
getAccessToken(oauth2Client, function() {
  // retrieve user profile
  plus.people.get({ userId: 'me', auth: oauth2Client }, function(err, profile) {
    if (err) {
      console.log('An error occured', err);
      return;
    }
    console.log(profile.displayName, ':', profile.tagline);
  });
}); 

function getAccessToken(oauth2Client, callback) {
    // request access token
    oauth2Client.getToken(code, function(err, tokens) {
      // set tokens to the client
      // TODO: tokens should be set by OAuth2 client.
      oauth2Client.setCredentials(tokens);
      callback();
    });
}   
});

Your CLIENT_ID and CLIENT_SECRET parameters are respectively id here and secret here. In other words, they're not real client IDs and client secrets, which causes the credentials to be null, since those credentials are set from tokens you get in OAuth2Client.getToken.

Basically, you need to use actual credentials. You can learn how to do that in the Authorizing and Authenticating section of the readme.

Thanks for your answer. I did not show the real CLIENT_ID and CLIENT_SECRET here, but in my code, I really use those credentials from Google Developers Conole I set up.
