使用PHP Lib v2、Oauth 2.0使用Google 登录。
经过长时间的配置,我终于配置了它,它曾经正常工作,但之后就无法正常工作。点击登录链接后,用户将向 Google 进行身份验证。在完成身份验证之前工作正常。
在使用GET
变量进行回调时:
?code=something&authuser=0&prompt=consent&session_state=something
它正在生成以下错误:
致命错误:C:\xampp\htdocs\test\google-api-php-client\src\auth\Google_OAuth2.php:115 中的消息“获取 OAuth2 访问令牌时出错,消息:'invalid_client'”未捕获异常“Google_AuthException”堆栈跟踪:#0 C:\xampp\htdocs\test\google-api-php-client\src\Google_Client.php(127): Google_OAuth2->authenticate(Array, 4/xUGSPbXR0LNzW...') #1 C: \xampp\htdocs\test\google-api-php-client\index.php(40): Google_Client->authenticate('4/xUGSPbXR0LNzW...') #2 {main} 在 C:\xampp\htdocs\第 115 行的 test\google-api-php-client\src\auth\Google_OAuth2.php
使用以下代码(它将帮助您理解):
<?php
ini_set('display_errors',1);
error_reporting(E_ALL);
require_once 'src/Google_Client.php';
require_once 'src/contrib/Google_PlusService.php';
session_start();
$client = new Google_Client();
$client->setApplicationName("Google+ PHP Starter Application");
$plus = new Google_PlusService($client);
if (isset($_REQUEST['logout'])) {
unset($_SESSION['access_token']);
}
if (isset($_GET['code'])) {
$client->authenticate($_GET['code']);
$_SESSION['access_token'] = $client->getAccessToken();
header('Location: http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']);
}
if (isset($_SESSION['access_token'])) {
$client->setAccessToken($_SESSION['access_token']);
}
if ($client->getAccessToken()) {
$me = $plus->people->get('me');
$url = filter_var($me['url'], FILTER_VALIDATE_URL);
$img = filter_var($me['image']['url'], FILTER_VALIDATE_URL);
$name = filter_var($me['displayName'], FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);
$personMarkup = "<a rel='me' href='$url'>$name</a><div><img src='$img'></div>";
$optParams = array('maxResults' => 100);
$activities = $plus->activities->listActivities('me', 'public', $optParams);
$activityMarkup = '';
foreach($activities['items'] as $activity) {
$url = filter_var($activity['url'], FILTER_VALIDATE_URL);
$title = filter_var($activity['title'], FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);
$content = filter_var($activity['object']['content'], FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);
$activityMarkup .= "<div class='activity'><a href='$url'>$title</a><div>$content</div></div>";
}
$_SESSION['access_token'] = $client->getAccessToken();
} else {
$authUrl = $client->createAuthUrl();
}
?>
