为什么无法获取用户访问令牌（离线）来管理页面？
i'm trying to write a script to post to a page while the admin is offline. my application has the manage_pages extended permission of the admin user. here is my code:
require('php-sdk/src/facebook.php');
$facebook = new Facebook(array(
'appId' => 'MY_APP_ID', // YOUR APP ID
'secret' => 'MY_SECRET', // YOUR API SECRET
'cookie' => true
));
$user_admin_id = 'MY_ADMIN_ID';
$page_id = 'MY_PAGE_ID';
//get the access token to post to my page via the graph api
$accounts = $facebook->api("/" . $user_admin_id . "/accounts");
foreach ($accounts['data'] as $account)
{
if ($account['id'] == $page_id)
{
//found the access token, now we can break out of the loop
$page_access_token = $account['access_token'];
break;
}
}
but I always get this message:
"Fatal error: Uncaught OAuthException: A user access token is required to request this resource. thrown in /home/itrade10/public_html/khodiersoftware/php-sdk/src/base_facebook.php on line 1033"
我正在尝试编写一个脚本，以便在管理员离线时发布到页面。 应用程序具有 manage_pages扩展了管理员用户的权限。 我的代码是： p>
require（'php-sdk / src / facebook.php'）;
$ facebook = new Facebook （数组（
'appId'=＆gt;'MY_APP_ID'，//你的APP ID
'秘密'=＆gt;'MY_SECRET'，//你的API SECRET
'cookie'=＆gt; true
）） ;
$ user_admin_id ='MY_ADMIN_ID';
$ page_id ='MY_PAGE_ID';
//通过图表api
$ accounts = $ facebook-＆gt;获取访问令牌以发布到我的页面 api（“/”。$ user_admin_id。“/ accounts”）;
foreach（$ accounts ['data'] as $ account）
{
if（$ account ['id'] == $ page_id）
{
//找到访问令牌，现在我们可以突破循环
$ page_access_token = $ account ['access_token'];
break;
}
}
code > pre>
但我总是收到此消息： p>
“致命错误：未捕获OAuthException：需要用户访问令牌
请求此资源。 在第1033行的
/home/itrade10/public_html/khodiersoftware/php-sdk/src/base_facebook.php
中引用“ p>

You forgot to authorize the User, that´s how you get a User Access Token:
https://developers.facebook.com/docs/reference/php/facebook-getLoginUrl/
Don´t forget to add the "manage_pages" permission in the scope Parameter. You will also have to use the Function "setExtendedAccessToken" of the PHP SDK to extend the User Token. After that, you will get a Page Access Token that is valid forever with the /me/accounts endpoint.
If you used getLoginUrl already, then there´s something wrong with that code, you may want to add it to the question.
Before getting the accounts (with /me/accounts, not with your id), get the User ID:
$user = $facebook->getUser();
If you got a valid User Token, your ID will be in the $user Variable.
The error message is telling you exactly what the problem is... you need to get a user access token to access your page tokens
