[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")) );
}
?>

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。
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));
