必須使用活動訪問令牌來查詢有關當前用戶的信息 訪問令牌似乎有效

[英]An active access token must be used to query information about the current user | Access token seems to be valid

我已經定義了一個訪問令牌並擁有“喜歡”Facebook頁面所需的權限,但是firebug一直在給我標題中的錯誤。 請不要將此帖標記為重復 ,因為我查看了有關問題的帖子,但我無法找到適合我特定情況的答案。 我無法理解為什么或如何解決它。 我的代碼如下:

utils.php中

    <?php
require_once('sdk/src/facebook.php');
require_once("AppInfo.php");
/**
 * @return the value at $index in $array or $default if $index is not set.
 */
function idx(array $array, $key, $default = null) {
  return array_key_exists($key, $array) ? $array[$key] : $default;
}

function he($str) {
  return htmlentities($str, ENT_QUOTES, "UTF-8");
}
$facebook = new Facebook(array(
'appId'  => AppInfo::appID(),
'secret' => AppInfo::appSecret(),
'sharedSession' => true,
'trustForwarded' => true,
'file_upload' =>true
));
$user_id = $facebook->getUser();
if($user_id)
{
  $logoutUrl =$facebook->getLogoutUrl();
}
  else
  {
      $loginUrl=$facebook->getLoginUrl();
  }
if ($user_id) {
try {
  // Fetch the viewer's basic information
  $user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
  // If the call fails we check if we still have a user. The user will be
  // cleared if the error is because of an invalid accesstoken
  if (!$facebook->getUser()) {
    header('Location: '. AppInfo::getUrl($_SERVER['REQUEST_URI']));
    exit();
  }
}
}
?>

likes.php

      <?php

require_once("sdk/src/facebook.php"); 
require_once("utils.php");
require_once("AppInfo.php");
$permissions = $facebook->api('/me/permissions    ');
if( array_key_exists('publish_actions', $permissions['data'][0]) ) {
    // Permission is granted!
    // Do the related task
    //$post_id = $facebook->api('/me/feed', 'post', array('message'=>'Hello World!'));
} else {
    // We don't have the permission
    // Alert the user or ask for the permission!
    header( "Location: " . $facebook->getLoginUrl(array("scope" => "publish_actions")) );
}
?>
    <!DOCTYPE html>
    <html xmlns:fb="http://ogp.me/ns/fb#">
    <head>

      <style type="text/css">
      li{ 
        vertical-align: middle;
        padding-top: 1em; 
      }
    </style>
    <div id="fb-root"></div>

     <script type="text/javascript">

      (function(d, debug){
         var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
         if (d.getElementById(id)) {return;}
         js = d.createElement('script'); js.id = id; js.async = true;
         js.src = "//connect.facebook.net/en_US/all" + (debug ? "/debug" : "") + ".js";
         ref.parentNode.insertBefore(js, ref);
       }(document, false)); //loads javascript-sdk

        $(function() {
          // Set up so we handle click on the buttons
          $('#like_but').click(function(){
          FB.api(
      'me/og.likes',
      'post',
      {
        object: "http://facebook.com/216730015024772"
      },
      function(response) {
        alert(response);
      });});}); // they are closed properly, don't bother checking it. (!) Should like the 'object'
     </script>
    </head>
    <body> 
    <div style="position:fixed; display:block">
      <input type="button" value="Like" id="like_but"/>
 </div>    
</body>
</html>

有沒有人知道為什么會出現錯誤或如何解決這個問題? 任何提示都將不勝感激。

注意:用戶從另一個index.php登錄,但我不會在此處發布,因為它沒有問題,訪問令牌仍然在utils.php中收集。 此外,當檢查是否在“likes.php”中授予權限時,它工作正常。

假設您從Facebook收到的access_token確實有效......看起來您的Facebook javascript SDK的實現並不完整。

你已經包含了庫加載器,但你沒有FB.init(); 部分初始化庫。 我看不到第二個代碼塊中任何appId引用,因此Facebook有辦法知道您的代碼所引用的應用程序。

請參閱Facebook以下文檔

具體來說,這可以解決您的問題:

window.fbAsyncInit = function() {
    // init the FB JS SDK
    FB.init({
        appId      : 'YOUR_APP_ID', // App ID from the App Dashboard
        channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File for x-domain communication
        status     : true, // check the login status upon init?
        cookie     : true, // set sessions cookies to allow your server to access the session?
        xfbml      : true  // parse XFBML tags on this page?
    });

    // Additional initialization code such as adding Event Listeners goes here
    document.getElementById('like_but').addEventListener('click', function() {
        FB.api('me/og.likes', 'post', {
            object: "http://facebook.com/216730015024772"
        }, function(response) {
            console.log(response);
        });
    }, false);
};

(function(d, debug){
    var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
    if (d.getElementById(id)) {return;}
    js = d.createElement('script'); js.id = id; js.async = true;
    js.src = "//connect.facebook.net/en_US/all" + (debug ? "/debug" : "") + ".js";
    ref.parentNode.insertBefore(js, ref);
}(document, /*debug*/ false));
