我正在尝试在我的网站上集成谷歌登录。我添加了compose并安装了googleauth2.0版本。
config.php的代码
<?php
//start session on web page
session_start();
//config.php
//Include Google Client Library for PHP autoload file
require_once 'vendor/autoload.php';
//Make object of Google API Client for call Google API
$google_client = new Google_Client();
//Set the OAuth 2.0 Client ID
$google_client->setClientId('XXXXXX');
//Set the OAuth 2.0 Client Secret key
$google_client->setClientSecret('XXXXXX');
//Set the OAuth 2.0 Redirect URI
$google_client->setRedirectUri('http://localhost/MMCOE_LINER/basic_login/login.php');
// to get the email and profile
$google_client->addScope('email');
$google_client->addScope('profile');
?>
index.php的代码
<?php
//Include Configuration File
include('config.php');
$login_button = '';
if(isset($_GET["code"]))
{
$token = $google_client->fetchAccessTokenWithAuthCode($_GET["code"]);
if(!isset($token['error']))
{
$google_client->setAccessToken($token['access_token']);
$_SESSION['access_token'] = $token['access_token'];
$google_service = new Google_Service_Oauth2($google_client);
$data = $google_service->userinfo->get();
echo $data;
if(!empty($data['given_name']))
{
$_SESSION['user_first_name'] = $data['given_name'];
}
if(!empty($data['family_name']))
{
$_SESSION['user_last_name'] = $data['family_name'];
}
if(!empty($data['email']))
{
$_SESSION['user_email_address'] = $data['email'];
}
if(!empty($data['gender']))
{
$_SESSION['user_gender'] = $data['gender'];
}
if(!empty($data['picture']))
{
$_SESSION['user_image'] = $data['picture'];
}
}
}
if(!isset($_SESSION['access_token']))
{
$login_button = '<a href="'.$google_client->createAuthUrl().'">Login With Google</a>';
}
?>

我在Xampp 上运行
所以，在运行index.php并选择我的Gmail帐户后，我收到了一个错误，完整的错误：

此外，经过一些调试，我发现错误在这里：
$token = $google_client->fetchAccessTokenWithAuthCode($_GET["code"]);
$data = $google_service->userinfo->get();
您似乎假设userinfo端点返回性别和姓名等信息。但事实并非如此。你甚至不能保证它有时会返回电子邮件和姓名。
尝试在数据变量上打印，看看实际返回的是什么
print_r($data);
这就是为什么我们使用people.get方法，因为您已经请求了配置文件范围，您应该可以访问它
