Google+登录,PHP一次性代码/服务器端流,没有"Silex/twig"
// Create a state token to prevent request forgery.
// Store it in the session for later validation.
$state = md5(rand());
$app['session']->set('state', $state);
// Set the client ID, token state, and application name in the HTML while
// serving it.
return $app['twig']->render('index.html', array(
'CLIENT_ID' => CLIENT_ID,
'STATE' => $state,
'APPLICATION_NAME' => APPLICATION_NAME
));
问题:如何在没有silex/twig的情况下进行服务器端工作？
我使用这个客户端库（PHP）
请测试这个代码它工作正常
index.php
<?php
session_start();
$data['state'] = md5(uniqid(rand(), true));
$_SESSION['state'] = $data['state'];
?>

加上.php

$client = new Google_Client();
$CLIENT_ID = 'CLIENT ID';
$client->setClientId($CLIENT_ID);
$client->setClientSecret('Client Secret');
$client->setRedirectUri('postmessage');
$code = explode(",",file_get_contents('php://input'));
if (isset($code[1]) && $code[1] === $_SESSION['state'])
{
$plus = new Google_PlusService($client);
$client->authenticate($code[0]);
$token = json_decode($client->getAccessToken());
// Verify the token
$reqUrl = 'https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=' .
$token->access_token;
$req = new Google_HttpRequest($reqUrl);
$tokenInfo = json_decode(
$client::getIo()->authenticatedRequest($req)->getResponseBody());
$userId = $tokenInfo->user_id;
$userEmail = $tokenInfo->email;
// If there was an error in the token info, abort.
if (isset($tokenInfo->error)) {
print $tokenInfo->error;
}
// Make sure the token we got is for our app.
if ($tokenInfo->audience != $CLIENT_ID) {
print "Token's client ID does not match app's.";
}
print 'Token from result: ' . print_r($token, true);
print '<<<<<<<<<<< tokenInfo >>>>>>> ' . print_r($tokenInfo, true);
}
else
{
echo "Invalid state parameter";
}
不要忘记添加您的CLIENT ID和Client Secret。
注销在本地主机中不起作用。
