动态生成 Facebook Open Graph 元标记更新：
2022-08-30 10:24:38
正如标题所暗示的那样，我正在尝试动态生成Facebook Open Graph元标记，但我无法让它工作。这有可能吗？
更新：
最后，我在@saccharine的帮助下完成了它。以下代码对我有用：
<?php
$params = array();
if(count($_GET) > 0) {
$params = $_GET;
} else {
$params = $_POST;
}
// defaults
if($params['type'] == "") $params['type'] = "restaurant";
if($params['locale'] == "") $params['locale'] = "en_US";
if($params['title'] == "") $params['title'] = "default title";
if($params['image'] == "") $params['image'] = "thumb";
if($params['description'] == "") $params['description'] = "default description";
?>

<!-- Open Graph meta tags -->
<meta property="fb:app_id" content="MY_APP_ID" />
<meta property="og:site_name" content="meta site name"/>
<meta property="og:url" content="http://mysite.com/index.php?type=<?php echo $params['type']; ?>&locale=<?php echo $params['locale']; ?>&title=<?php echo $params['title']; ?>&image=<?php echo $params['image']; ?>&description=<?php echo $params['description']; ?>"/>
<meta property="og:type" content="MY_APP_NAME_SPACE:<?php echo $params['type']; ?>"/>
<meta property="og:locale" content="<?php echo $params['locale']; ?>"/>
<meta property="og:title" content="<?php echo $params['title']; ?>"/>
<meta property="og:image" content="http://mysite.com/img/<?php echo $params['image']; ?>.png"/>
<meta property="og:description" content="<?php echo $params['description']; ?>"/>
</head>
</html>
我现在放入Facebook调试器中的URL可以包含任何动态参数，甚至不包含任何动态参数，全部或仅包含一个选择，并且以任何顺序（如so：
http://mysite.com/index.php?type=restaurant&title=luigis
或this：
http://mysite.com/index.php?locale=de_DE&description=hi&type=bistro
完成此操作后：我现在可以将操作发布到用户的流中：
function postRestaurant() {
FB.api('me/MY_APP_NAMESPACE:have_lunch?\
start_time=2000-12-12T04:00:00&\
expires_in=7200&\
restaurant=' + encodeURIComponent(getRedirectURI() + '?type=restaurant' + '&description=arnold' + '&title=stalone'), 'post', function (response) {
if (!response || response.error) {
console.log('postRestaurant: Error occured => ' + response.error.message);
} else {
console.log('postRestaurant: Post was successful! Action ID: ' + response.id);
}
});
}
像魔咒一样工作！: ]
