[英]Sending Google+ Hybrid server-side flow one time authorization code over HTTP Safe?
[英]Google+ sign in, PHP one-time-code/server-side flow without “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
));
問題:如何在沒有silex / twig的情況下進行服務器端工作?
有兩個答案,因為有兩個你想要沒有的庫。
對於第一個(Silex):
// Create a state token to prevent request forgery.
// Store it in the session for later validation.
$state = md5(rand());
$app['session']->set('state', $state);
這只是存儲一個會話變量供以后使用。 這可以在PHP中輕松完成:
<?php
session_start();
$state = md5(rand());
$_SESSION['state'] = $state;
?>
稍后,您將通過比較客戶端發送到$_SESSION['state']
來驗證來自客戶端的正確狀態值。
第二部分(Twig):
// 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
));
這只是用已知值替換渲染HTML中的值。 您可以通過將示例index.html中的{{ VARIABLE_NAME }}
每個實例替換為PHP變量(例如將{{ CLIENT_ID }}
更改為<?php echo $CLIENT_ID; ?>
)來實現此目的,然后,當然,在代碼中設置該變量。
然后,您將調用您的PHP腳本,並讀入您的腳本並返回index.html
文件。
// Ensure that this is no request forgery going on, and that the user
// sending us this connect request is the user that was supposed to.
if ($request->get('state') != ($app['session']->get('state'))) {
return new Response('Invalid state parameter', 401);
}
而是使用:
if ($_REQUEST['state'] != $_SESSION['state'])) {
header("HTTP/1.1 401 Unauthorized");
echo "Invalid state parameter";
exit;
}
對於第8步:初始化Google API客戶端庫並啟動Google+服務 :
對於return new Response('{Message}', {HTTP status code});
每一行return new Response('{Message}', {HTTP status code});
用它替換它
header("HTTP/1.1 {HTTP status code});
echo "{Message}";
exit;
然后而不是
// Store the token in the session for later use.
$app['session']->set('token', json_encode($token));
$response = 'Succesfully connected with token: ' . print_r($token, true);
放
// Store the token in the session for later use.
$_SESSION['token'] = json_encode($token));
$response = 'Succesfully connected with token: ' . print_r($token, true);
我用這個客戶端庫(PHP)
請測試此代碼,它工作正常
的index.php
<?php
session_start();
$data['state'] = md5(uniqid(rand(), true));
$_SESSION['state'] = $data['state'];
?>
