Question

Could any one please paste some sample code or any suggestions on how to get the email address from the google plus API?

Answer 1

You can retrieve a user's email address if they specifically authorize your application to see their email address.

Set your scopes to:

https://www.googleapis.com/auth/plus.login
https://www.googleapis.com/auth/userinfo.email

The JavaScript calls look like this:

gapi.client.load('oauth2', 'v2', function() {
  gapi.client.oauth2.userinfo.get().execute(function(resp) {
    // Shows user email
    console.log(resp.email);
  })
});

gapi.client.load('plus', 'v1', function() {
  gapi.client.plus.people.get( {'userId' : 'me'} ).execute(function(resp) {
    // Shows other profile information
    console.log(resp);
  })
});

Note that you do not need scopes for plus.me or userinfo.profile.

Answer 2

Exposing E-mail addresses of people who have not set it to be visible to 'Public' would obviously be a privacy issue, so that's not possible.

Exposing E-mail addresses of people who have set their E-mail address visibility to 'Public' is possible, but not yet there. It is currently an open issue
