我已经定义了一个访问令牌，并拥有"喜欢"facebook页面所需的权限，但firebug一直在标题中给我错误。请不要把这篇文章标记为重复的，因为我已经看过了关于这个问题的帖子，我找不到一个适合我特殊情况的答案。我不明白为什么，也不知道该怎么解决。我的代码如下:
utils.php
<?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")) );
}
?>

有没有人知道为什么会出现错误或者我该如何解决这个问题?如有任何提示，不胜感激。
注意:用户从另一个index.php登录，但我不会在这里发布它，因为它没有问题，并且访问令牌仍然收集在utils.php中。当检查权限是否在"like .php"中被授予时，它工作得很好。
假设你从Facebook收到的access_token确实是有效的…看起来你的Facebook javascript SDK的实现是不完整的。
您已经包含了库加载器，但是您没有一个FB.init();节来初始化库。我在第二个代码块中没有看到任何appId的参考，所以Facebook有办法知道你的代码是参考什么应用程序。
请参考Facebook的以下文档
具体来说，这可以解决您的问题:
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));
