javascript - Passport-Facebook authentication is not providing email for all Facebook accounts -


i using passport-facebook authentication.

   passport.use(new facebookstrategy({             clientid: 'client_id',             clientsecret: 'client_secret',             callbackurl: "http://www.example.com/auth/facebook/callback"         },         function (accesstoken, refreshtoken, profile, done) {                         process.nexttick(function () {                                console.log(profile)             });                        }     ));

for of facebook accounts don't email_id , tried using scope variable such below, still unable email_id.

profileurl : " " , profilefields : ['','']

make sure these 2 things in code:

  passport.use(new facebookstrategy({             clientid: 'client_id',             clientsecret: 'client_secret',             callbackurl: "http://www.example.com/auth/facebook/callback"             passreqtocallback : true,             profilefields: ['id', 'emails', 'name'] //this         },

and this:

app.get('/connect/facebook', passport.authorize('facebook', { scope : ['email'] }));

this gives access following:

  • profile.id
  • profile.name.givenname
  • profile.name.familyname
  • profile.emails

the last 1 being array, use profile.emails[0].value first email address of user.

as shamim reza pointed out, might want check if profile.emails !== undefined because property exists if user has @ least 1 verified email address.
