我正在创建一个使用PHP SDK在facebook上创建即时文章的代码。我创建了一个使用它的登录，并添加了＆＃39; public_profile，email，manage_pages，pages_show_list，pages_manage_instant_articles＆＃39;权限。
当用户点击登录按钮时，它会要求所有这些权限。如果用户是页面的管理员并且他使用它登录，则他能够在该页面上创建即时文章。但是当用户具有该页面的编辑角色，尝试登录时，他被要求获得所有这些权限，即使他允许所有这些权限，他仍然无法创建即时文章。在错误日志中，出现如下错误：
PHP致命错误：未捕获Facebook \ Exceptions \ FacebookAuthorizationException：（＃200）需要扩展权限：pages_manage_instant_articles in ../facebook-php-sdk-v4-5.0.0/src/Facebook/Exceptions/FacebookResponseException.php:120
首次登录时，编辑用户被要求获得所有权限并且他批准了所有权限，但仍然发生此错误。现在当他再次尝试登录时，他没有被要求获得权限。我已经检查了编辑角色用户的权限，但是＃34; / me / permissions＆＃34;端点。作为回应，＆＃34;电子邮件，user_friends，pages_show_list和public_profile＆＃34;权限具有状态＆＃34;已授予＆＃34;，但没有关于＆＃34; manage_pages和pages_manage_instant_articles＆＃34;的任何详细信息。权限。
对于管理员角色用户，所有代码都运行良好，即时文章也是使用PHP SDK创建的，但此问题仅适用于编辑角色用户。
这是我尝试过的代码，我没有在这里包含我的app-id，app-secret，page-id和article-html：
<?php
session_start();
$page_id = '{page-id}';
$app_id='{app-id}';
$app_secret='{app-secret}';
require_once 'testing/facebook-php-sdk-v4-5.0.0/src/Facebook/autoload.php';
if(!isset($_GET['user'])){
