Save user data in MongoDB after user registers by their google account-CodePudding

I'm developing an application that will allow users to access the website after authenticating with their Facebook or Google IDs. and this will be done by front-end and in the back-end front-end side will send only the access-token something like this: ya29.a0AVA9y1tHwvchD95jJmDNMzKkW7P9nIAyvHX58AY-bC_Dy_-7lhXkrXpfe8iRXIrLHbDKZRFmzphfMceFH3di6X_2-_FcwiXa8GvDwOmYwwzgt1MUETzlFRrcnuWDDbAsa2Yj00BFDyAqK6fuO8smUYmyXw1taCgFRDTASAQASFQE65dr8E1cHOK0krpI8Efn0d9eXDg7852

Now, Based on this access token how can I get details of that user and save it to the database.

CodePudding user response：

You can retrieve the user profile using the google node API client library. In this case, please retrieve the access token and refresh token as the scope of https://www.googleapis.com/auth/userinfo.profile. The sample script is as follows. When you use this sample, please set your ACCESS TOKEN.

var google = require('googleapis').google;
var OAuth2 = google.auth.OAuth2;
var oauth2Client = new OAuth2();
oauth2Client.setCredentials({access_token: 'ACCESS TOKEN HERE'});
var oauth2 = google.oauth2({
  auth: oauth2Client,
  version: 'v2'
});
oauth2.userinfo.get(
  function(err, res) {
    if (err) {
       console.log(err);
    } else {
       console.log(res);
       /*WRITE SIMPLE MongoDB INSERT LOGIC HERE*/
        db.users.insert(res)

    }
});

From above logic you'll be able to get user details and insert it in MongoDB
