Google plus API shutdown, How it will affect Google auth2 login for web sites? - google-plus

Question

I am confused with shutdown notification mails from Google one of the recent mail mentioned as
projects directly requesting the “plus.me” scope are affected. This scope may have been listed in some emails, even if not directly
requested by your project. We apologize for any confusion caused.
I am using following JS code for login, may I know will it affect anyway due to Google plus api shutdown?
<script async defer src="https://apis.google.com/js/api.js" onload="this.onload=function(){};HandleGoogleApiLibrary()" onreadystatechange="if (this.readyState === 'complete') this.onload()"></script>
<script type="text/javascript">
//google login starts
function HandleGoogleApiLibrary() {
// Load "client" & "auth2" libraries
gapi.load('client:auth2', {
callback: function() {
// Initialize client library
// clientId & scope is provided => automatically initializes auth2 library
gapi.client.init({
apiKey: 'API KEY HERE',
clientId: 'XXXXXXXXXXXXXXXXX.apps.googleusercontent.com',
scope: 'https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email'
}).then(
// On success
function(success) {
// After library is successfully loaded then enable the login button
//CODE AFTER SUCCESS
},
// On error
function(error) {
alert('Error : Failed to Load Library');
}
);
},
onerror: function() {
// Failed to load libraries
}
});
}
// Click on login button
$("#login-button").on('click', function() {
// API call for Google login
gapi.auth2.getAuthInstance().signIn().then(
// On success
function(success) {
// API call to get user information
gapi.client.request({ path: 'https://www.googleapis.com/plus/v1/people/me' }).then(
// On success
function(success) {
console.log(success);
var user_info = JSON.parse(success.body);
//VALIDATION
},
// On error
function(error) {
alert('Error : Failed to login');
}
);
},
// On error
function(error) {
$("#login-button").removeAttr('disabled');
alert('Error : Login Failed');
}
);
});

There is good news and bad news.
The good news is that you're not using any of the plus scopes.
The bad news is that you're using the plus API, which is also being shut down, and which was mentioned in a previous email that should have been sent to you.
Specifically, this chunk of code:
gapi.client.request({ path: 'https://www.googleapis.com/plus/v1/people/me' }).then(
calls the "plus.people.me" API.
Fortunately, you should be able to switch to a different API, such as the "userinfo" API, by changing endpoints to
https://www.googleapis.com/oauth2/v2/userinfo
You may also wish to look into the more modern People API, which works very similarly, and is slightly more complicated, but can provide other profile fields.
