示例代码来自 Google+ Sign-In for server-side apps 

  // 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？

最佳答案

我用这个Client Library(PHP)
请测试此代码是否正常工作
索引.php

<?php
session_start();
$data['state'] = md5(uniqid(rand(), true));
$_SESSION['state'] = $data['state'];
?>
<html itemscope itemtype="http://schema.org/Article">
<head>
  <!-- BEGIN Pre-requisites -->
  <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js">
  </script>
  <meta name="google-signin-scope" content="https://www.googleapis.com/auth/plus.login https://www.googleapis.com/auth/plus.moments.write https://www.googleapis.com/auth/plus.me https://www.googleapis.com/auth/plus.profile.agerange.read https://www.googleapis.com/auth/plus.profile.language.read https://www.googleapis.com/auth/plus.circles.members.read https://www.googleapis.com/auth/drive.file https://www.googleapis.com/auth/userinfo.email" />

  <script type="text/javascript">
    (function () {
      var po = document.createElement('script');
      po.type = 'text/javascript';
      po.async = true;
      po.src = 'https://plus.google.com/js/client:plusone.js';
      var s = document.getElementsByTagName('script')[0];
      s.parentNode.insertBefore(po, s);
    })();
  </script>
  <!-- END Pre-requisites -->
</head>
<body>
<!-- Add where you want your sign-in button to render -->
<div id="signinButton">
  <span class="g-signin"
    data-scope="https://www.googleapis.com/auth/plus.login"
    data-clientid="Your clientid"
    data-redirecturi="postmessage"
    data-accesstype="offline"
    data-cookiepolicy="single_host_origin"
    data-callback="signInCallback">
  </span>
</div>
<button id="signoutButton" style="display:none" onclick="signout()">signout</button>
<div id="result"></div>

<script type="text/javascript">
function signInCallback(authResult) {
  if (authResult['code']) {
    // Hide the sign-in button now that the user is authorized, for example:
    $('#signinButton').attr('style', 'display: none');
    $('#signoutButton').attr('style', 'display: block');
    var state = '<?php echo $_SESSION['state']; ?>';
    var param = new Array();
    var param = [authResult['code'],state];
    // Send the code to the server
    $.ajax({
      type: 'POST',
      url: 'plus.php?storeToken&state',
      contentType: 'application/octet-stream; charset=utf-8',
      success: function(result) {
        // Handle or verify the server response if necessary.
       console.log(result);
        alert('connected');
      },
      processData: false,
      data: param
    });
  } else if (authResult['error']) {
    alert('Could not automatially log in the user');
     console.log('There was an error: ' + authResult['error']);
  }
}

function signout(){ 
       gapi.auth.signOut();
        $('#signoutButton').attr('style', 'display: none');
        $('#signinButton').attr('style', 'display: block');
        console.log('sign out');
}
</script>
</body>
</html>

加.php

<?php
session_start();
require_once 'src/Google_Client.php';
require_once 'src/contrib/Google_PlusService.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。
注销不在本地主机上工作。
