我尝试与Facebook连接建立连接,但有一些错误。

Further Facebook Login Javascript Errors

我有这个链接的类似问题.Php $ _COOKIE没有找到相关的cookie

Notice: Undefined index: fbs_appID in /opt/lampp/htdocs/phpdeneme/index.php on line 10

Notice: Undefined index: sig in /opt/lampp/htdocs/phpdeneme/index.php on line 22

Warning: file_get_contents(https://graph.facebook.com/me?access_token=) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request in /opt/lampp/htdocs/phpdeneme/index.php on line 30



<?php


define('FACEBOOK_APP_ID', 'APP_ID');
define('FACEBOOK_APP_SECRET','SECRET_ID');


function get_facebook_cookie($appID,$appSecret){
    $args = array();
    parse_str(trim($_COOKIE['fbs_' . $appID], '\\"'), $args);


    ksort($args);
    $payload = '';
    foreach($args as $key=>$value){

        if($key != 'sig'){
            $payload .= $key . '=' . $value;
        }
    }

    if(md5($payload . $appSecret) != $args['sig'])
            return null;

    return $args;

}

$cookie = get_facebook_cookie(FACEBOOK_APP_ID, FACEBOOK_APP_SECRET);
$user = json_decode(file_get_contents('https://graph.facebook.com/me?access_token=' . $cookie['access_token']));

?>


    <html>
        <body>
            <?php if($cookie){ ?>

            Welcome <?= $user->name ?>
            <?php } else { ?>
        <fb: login-button></fb:login-button>
        <?php } ?>
        <div id="fb-root"></div>
        <script src="http://connect.facebook.net/en_US/all.js"></script>
        <script>
        FB.init({appId: '<?= FACEBOOK_APP_ID ?>' , status: true, cookie: true, xfbml:true});
        FB.Event.subscribe('auth.login',function(response){
           window.location.reload(); 

        });
        </script>

        </body>
         </html>

怎么了?少了什么东西 ?什么fbs cookie没有创建?

您使用旧的oauth 1.0格式。您现在必须使用新格式。

来自PHP代码的一个例子,应该足够接近,以最小的变化修改成js:

function get_facebook_cookie() {      $ CI =&amp; get_instance();      $ app_id = $ CI-&gt; config-&gt; item('facebook_app_id');      $ application_secret = $ CI-&gt; config-&gt; item('facebook_app_secret');       if(isset($ COOKIE ['fbsr '。$ app_id])){          list($ encoded_sig,$ payload)= explode('。',$ COOKIE ['fbsr '。$ app_id],2);

     $sig = base64_decode(strtr($encoded_sig, '-_', '+/'));
     $data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);

     if (strtoupper($data['algorithm']) !== 'HMAC-SHA256') {
         return null;
     }
     $expected_sig = hash_hmac('sha256', $payload,
     $application_secret, $raw = true);
      if ($sig !== $expected_sig) {
          return null;
      }
      $token_url = "https://graph.facebook.com/oauth/access_token?"
     . "client_id=" . $app_id . "&client_secret=" . $application_secret. "&redirect_uri=" . "&code=" . $data['code'];
      $response = file_get_contents($token_url);

      $params = null;
      parse_str($response, $params);
      $data['access_token'] = $params['access_token'];
      return $data;
  }else{
      return null;
 }

}
