Question

的示例代码

  // 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？

Answer 1

有两个答案，因为有两个你想要没有的库。

对于第一个（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);

这只是存储一个会话变量供以后使用。这可以在PHP中轻松完成：

<?php
session_start();

$state = md5(rand());
$_SESSION['state'] = $state;
?>

稍后，您将通过比较客户端发送给$_SESSION['state']的内容来验证客户端的正确状态值。

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
));

这只是用已知值替换渲染HTML中的值。您可以通过使用PHP变量替换示例index.html中的 {{ VARIABLE_NAME }} 的每个实例（例如将{{ CLIENT_ID }}更改为<?php echo $CLIENT_ID; ?>）来执行此操作，然后，当然，在代码中设置该变量。

然后，您将调用您的PHP脚本，并读入您的脚本并返回index.html文件。

修改对于Step 7: Confirm the anti-request forgery state token on the server

// 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); }

改为使用：

if ($_REQUEST['state'] != $_SESSION['state'])) { header("HTTP/1.1 401 Unauthorized"); echo "Invalid state parameter"; exit; }

Step 8: Initialize the Google API client library and start the Google+ service：

对于return new Response('{Message}', {HTTP status code});的每一行，将其替换为

header("HTTP/1.1 {HTTP status code}); echo "{Message}"; exit;

然后代替

// 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);

把

// Store the token in the session for later use. $_SESSION['token'] = json_encode($token)); $response = 'Succesfully connected with token: ' . print_r($token, true);

Answer 2

我使用此Client Library(PHP)
请测试此代码它是否正常工作
的index.php

<?php
session_start();
$data['state'] = md5(uniqid(rand(), true));
$_SESSION['state'] = $data['state'];
?>

请勿忘记添加CLIENT ID和Client Secret 退出不在localhost中工作。

Google+登录，PHP一次性代码/服务器端流程，没有＆＃34; Silex / twig＆＃34;
