我正在使用Facebook PHP SDK v5將帖子發佈到我管理的頁面。下面的代碼在發佈頁面鏈接時效果很好。然而，當我試圖修改此代碼以刪除它使返回錯誤後：如何使用PHP SDK v5從Facebook頁面中刪除帖子
Graph returned a page request error: Unknown path components: /xxxxxxx_xxxxxxxxx
xxxxxxx_xxxxxxxxx的是，我試圖刪除
我無法弄清楚如何調整帖子ID我的工作代碼刪除帖子，而不是發佈它們。有誰知道如何使這項工作？
工作代碼後發佈到頁面：
<?php

我在上面的修改工作代碼刪帖的嘗試。不工作：
基本上我改變了：
要：
$post = $fb->delete('/'.$pageID.'/feed/'.$postIDtoDelete ,array(), $pageAccessToken);
代碼：

$postIDtoDelete = 'xxxxxxx_xxxxxxxxx';
$linkToPost = 'https://www.test-post.com';
$fb = new Facebook\Facebook([
'app_id' => 'xxxxxxxxxxx',
'app_secret' => 'xxxxxxxxxxxxxxxxxxxxxxxxxx',
'default_graph_version' => 'v2.10',
]);
$helper = $fb->getRedirectLoginHelper();
try {
if (isset($_SESSION['facebook_access_token'])) {
$accessToken = $_SESSION['facebook_access_token'];
} else {
$accessToken = $helper->getAccessToken();
}
} catch(Facebook\Exceptions\FacebookResponseException $e) {
