我想知道如何使用php获得page access token。我做的每件事都不会返回访问令牌。
第一个代码如下，工作并以用户身份发布消息。但我需要发布一个页面，根据文档，我需要一个页面访问令牌才能发布为页面/应用程序。
所以我将我的工作代码（第一个代码）编辑到第二个代码（返回一个空白页面）。
有人可以告诉我丢失的内容或我做错了吗？
以用户身份发布的工作代码：
<?php
include_once 'inc/facebook.php';
$appId = '00000000000000000';
$secret = '00000000000000000000000000000';
$returnurl = 'https://mydomain.com';
$permissions = 'manage_pages, publish_actions';
$fb = new Facebook(array('appId'=>$appId, 'secret'=>$secret));
$fbuser = $fb->getUser();
if($fbuser){
if(isset($_POST['msg']) and $_POST['msg']!=''){
try{
$message = array(
'message' => $_POST['msg']
);
$posturl = '/'.$_POST['pageid'].'/feed';
$result = $fb->api($posturl,'POST',$message);
if($result){
echo 'Successfully posted to Facebook Wall...';
}
}catch(FacebookApiException $e){
echo $e->getMessage();
}
}
try{
$qry = 'select page_id, name from page where page_id in (select page_id from page_admin where uid ='.$fbuser.')';
$pages = $fb->api(array('method' => 'fql.query','query' => $qry));
if(empty($pages)){
echo 'The user does not have any pages.';
}else{
echo '<form action="" method="post">';
echo 'Select Page: <select name="pageid">';
foreach($pages as $page){
echo '<option value="'.$page['page_id'].'">'.$page['name'].'</option>';
}
echo '</select>';
echo '<br />Message: <textarea name="msg"></textarea>';
echo '<br /><input type="submit" value="Post to wall" />';
echo '</form>';
}
}catch(FacebookApiException $e){
echo $e->getMessage();
}
}else{
$fbloginurl = $fb->getLoginUrl(array('redirect-uri'=>$returnurl, 'scope'=>$permissions));
echo '<a href="'.$fbloginurl.'">Login with Facebook</a>';
}
echo $page_info['access_token']
?>
第二个/已编辑的代码，当从浏览器查看时返回空白页：
<?php
include_once 'inc/facebook.php';
$appId = '0000000000000';
$secret = '000000000000000000000000000';
$returnurl = 'https://mydomain.com';
$permissions = 'manage_pages, publish_actions';
$fb = new Facebook(array('appId'=>$appId, 'secret'=>$secret));
$fbuser = $fb->getUser();
if($fbuser){
if(isset($_POST['msg']) and $_POST['msg']!=''){
try{
$page_info = $facebook->api("/$pageId?fields=access_token");
if (!empty($page_info['access_token'])) {
$message = array(
'access_token' => $page_info['access_token'],
'message' => $_POST['msg']
);
$posturl = '/'.$_POST['pageid'].'/feed';
$result = $fb->api($posturl,'POST',$message);
if($result){
echo 'Successfully posted to Facebook Wall...';
}
}
}catch(FacebookApiException $e){
echo $e->getMessage();
}
}
try{
$qry = 'select page_id, name from page where page_id in (select page_id from page_admin where uid ='.$fbuser.')';
$pages = $fb->api(array('method' => 'fql.query','query' => $qry));
if(empty($pages)){
echo 'The user does not have any pages.';
}else{
echo '<form action="" method="post">';
echo 'Select Page: <select name="pageid">';
foreach($pages as $page){
echo '<option value="'.$page['page_id'].'">'.$page['name'].'</option>';
}
echo '</select>';
echo '<br />Message: <textarea name="msg"></textarea>';
echo '<br /><input type="submit" value="Post to wall" />';
echo '</form>';
}
}catch(FacebookApiException $e){
echo $e->getMessage();
}
}else{
$fbloginurl = $fb->getLoginUrl(array('redirect-uri'=>$returnurl, 'scope'=>$permissions));
echo '<a href="'.$fbloginurl.'">Login with Facebook</a>';
}
?>
编辑，这将生成访问令牌，但我不确定它是否是页面访问令牌，或者它是用户访问令牌，因为所有页面的访问令牌都相同： < / p>
include_once 'inc/facebook.php';
$appId = '000000000000000000';
$secret = '000000000000000000000000000000';
$returnurl = 'https://mydomain.com';
$permissions = 'manage_pages, publish_actions';
$fb = new Facebook(array('appId'=>$appId, 'secret'=>$secret));
$fbuser = $fb->getUser();
if($fbuser){
if(isset($_POST['msg']) and $_POST['msg']!=''){
try{
$message = array(
'message' => $_POST['msg']
);
$posturl = '/'.$_POST['pageid'].'/feed';
//$posturl2 = '/'.$_POST['pageid'].'/tabs';
//$result2 = $fb->api($posturl2,"post", array("access_token" => $pageAccessToken, "app_id" => $appId));
$result = $fb->api($posturl,'POST',$message);
if($result){
echo 'Successfully posted to Facebook Wall...';
}
}catch(FacebookApiException $e){
echo $e->getMessage();
}
}
try{
$qry = 'select page_id, name from page where page_id in (select page_id from page_admin where uid ='.$fbuser.')';
$pages = $fb->api(array('method' => 'fql.query','query' => $qry));
$pageIds=$fb->api('/me/accounts');
$pageAccessToken=$pageIds["data"][1]["access_token"];
if(empty($pages)){
echo 'The user does not have any pages.';
}else{
echo '<form action="" method="post">';
echo 'Select Page: <select name="pageid">';
foreach($pages as $page){
echo '<option value="'.$page['page_id'].'">'.$page['name'].'</option>';
}
echo '</select>';
echo 'Select Page: <select name="pageid">';
foreach($pageIds as $pageId){
echo '<option value="'.$page['page_id'].'">'.$pageAccessToken.'</option>';
}
echo '</select>';
echo '<br />Message: <textarea name="msg"></textarea>';
echo '<br /><input type="submit" value="Post to wall" />';
echo '</form>';
}
}catch(FacebookApiException $e){
echo $e->getMessage();
}
}else{
$fbloginurl = $fb->getLoginUrl(array('redirect-uri'=>$returnurl, 'scope'=>$permissions));
echo '<a href="'.$fbloginurl.'">Login with Facebook</a>';
}
echo $pageAccessToken;

我不太可能通过你的一堆代码。但你想要的很简单。只需按照以下步骤操作即可 -
（我会在用户成功授予manage_pages和publish_stream权限后开始
\GET /{page-id}?fields=access_token
使用页面访问令牌在页面上发布供稿 -
\POST /{page-id}/feed?fields=page_access_token //send any parameters with this
那就是它！

这些访问令牌与用户访问令牌类似，不同之处在于它们为读取，写入或修改属于Facebook页面的数据的API提供权限。要获取页面访问令牌，您需要先获取用户访问令牌并询问manage_pages权限。获得用户访问令牌后，您将通过Graph API获取页面访问令牌。 授予此权限后，您可以使用以下Graph API请求检索页面访问令牌：
