Google Api 获取用户电子邮件地址

我正在使用 Google Api PHP 客户端登录用户。我想获取用户的电子邮件地址。我有以下代码。

Scope:

$client->setScopes('https://www.googleapis.com/auth/userinfo.profile');

Code:

$request = new apiHttpRequest("https://www.googleapis.com/oauth2/v2/userinfo?alt=json");
$userinfo = $client->getIo()->authenticatedRequest($request);

$response = $userinfo->getResponseBody();
print "<pre>" . print_r(json_decode($response, true), true) . "</pre>";

这仅给我以下详细信息

Array
(
    [id] => 110084312800396764
    [name] => Harsha M V
    [given_name] => Harsha M
    [family_name] => V
    [picture] => https://lh6.googleusercontent.com/-Xusc8lwgLIQ/AAAAAAAAAAI/AAAAAAAAAAA/sOthy23uJGk/photo.jpg
    [locale] => en
)

在数组中设置范围就可以完成这项工作。

$this->client->setScopes(array('https://www.googleapis.com/auth/analytics.readonly', 'https://www.googleapis.com/auth/userinfo.email', 'https://www.googleapis.com/auth/userinfo.profile'));
