Google+ login via Javascript and PHP

Question

Can you tell me please, how can I get user data(name, email) via Google+ Javascript/Php api? I go according this tutorial, which describes how to get authResult['code'] via Javascript.

Thats ok I have it. I send it to server via Ajax but I don't know how to get user data like name and email via PHP BUT without any redirects. Here are the samples of code Javascript:

function googleStart()
{
    console.log('googleStart');
    gapi.load('auth2', function()
    {
        auth2 = gapi.auth2.init({
            client_id: '811214467813-v3fmui5dfghte5m0kmohsf6dl11ori3tg.apps.googleusercontent.com',
            // Scopes to request in addition to 'profile' and 'email'
            fetch_basic_profile: false,
            scope: 'profile email'
        });
    });
}

function googleSignIn(authResult)
{
    console.log(authResult);

    if (authResult['code']) {

        console.log(authResult);

        // Hide the sign-in button now that the user is authorized, for example:
        $('#signinButton').attr('style', 'display: none');

        // Send the code to the server
        $.ajax({
            type: 'POST',
            url : "{link :Signgoogle:in}",
            accepts : 'json',
            // Spýtať sa na DJPW čo to tu je zakomentované
            //contentType: 'application/octet-stream; charset=utf-8',
            //processData: false,
            data : {
                'code' : authResult['code'],
                'id_token' : authResult.getAuthResponse().id_token
            },
...

PHP:

public function actionIn()
{
    $code = $_POST['code'];

    $client = new \Google_Client();
    $client->setClientId(self::APP_ID);
    $client->setClientSecret(self::APP_SECRET);
    $client->setRedirectUri(self::REDIRECT_URI);

    $client->authenticate($code);
    $access_token = $client->getAccessToken();
    $client->setAccessToken($access_token);

    $client->getAuth();


    $data = $access_token;

    if($data)
    {
        $this->sendJson(array($data));
    }
    else
    {
        $data = array('error' => '$client->verifyIdToken($id) skočil chybou.');
        $this->sendJson($data);
    }

}
....

PHP retrieves an access_token but no users data. Ofcourse it is an ajax call so I can't do any redirects as Google describes on every page. Can you help me please I can't find any solution.

Thank you very much.

Answer 1

Once you have an authenticated client for the user you will want to make a request to the Google+ people.get API method.

$client = new Google_Client();
$client->setClientId(CLIENT_ID);
$client->setClientSecret(CLIENT_SECRET);
$client->setRedirectUri(REDIRECT_URI);
$client->setAccessToken($access_token);
$plus = new Google_Service_Plus($client);
$me = $plus->people->get('me');
print "ID: {$me['id']}\n";
print "Display Name: {$me['displayName']}\n";
print "Image Url: {$me['image']['url']}\n";
print "Url: {$me['url']}\n";

For their email you will have to iterate over the $me['emails'] array and find the value with type=account.

Answer 2

if you are not using google client library you can use this google api For getting the client details you just pass the token to this api https://www.googleapis.com/oauth2/v3/tokeninfo?id_token= < your_token >

$response = file_get_contents ( 'https://www.googleapis.com/oauth2/v3/tokeninfo?id_token=' . $_REQUEST['token'] );

$response = json_decode ( $response );

echo "<pre>";
print_r ( $response );
echo "</pre>";

This will authenticate the user and it will return object

stdClass Object
(
    [iss] => accounts.google.com
    [at_hash] => hE0R********nxg
    [aud] => 79*********************p.apps.googleusercontent.com
    [sub] => 1028*****2
    [email_verified] => true
    [azp] => 7945823****p.apps.googleusercontent.com
