When passport doesn't return the profile.emails, profile.name.givenName, profile.name.familyName
fields, or if they are missing, you can try to parse the https://graph.facebook.com/v3.2/
url, although you still need a token. You access the url, with of course a valid token, like:
https://graph.facebook.com/v3.2/me?fields=id,name,email,first_name,last_name&access_token=
It outputs a JSON response like:
{
"id": "5623154876271033",
"name": "Kurt Van den Branden",
"email": "kurt.vdb\u0040example.com",
"first_name": "Kurt",
"last_name": "Van den Branden"
}
Install the request module ($ npm install request --save
), to be able to parse a JSON url and in your passport.js file:
const request = require("request");
passport.use(new FacebookStrategy({
clientID : 'CLIENT_ID',
clientSecret : 'CLIENT_SECRET',
callbackURL : "https://example.com/auth/facebook/callback"
},
function(req, token, profile, done) {
let url = "https://graph.facebook.com/v3.2/me?" +
"fields=id,name,email,first_name,last_name&access_token=" + token;
request({
url: url,
json: true
}, function (err, response, body) {
let email = body.email; // body.email contains your email
console.log(body);
});
}
));
You can add a lot of other parameters to the url, although some of them require user permission to return values. You can play with it on: https://developers.facebook.com/tools/explorer/
email
permission anywhere … you said you tried to use scope, but where? And no, people do not have to give an email address to register for FB, as I already said. – CBroeaccessToken
there and try it with the Graph API Explorer. Make sure that the "email" permission on the left is not greyed out. If it is, you're not asking for the scope at the right time. See this comment on the passport-facebook project. – a paid nerd
