Facebook PHP发布到粉丝页面与cronjob？

我使用以下代码发布到我的Facebook粉丝页面,它工作正常.现在我想使用cronjob发布到Facebook.我知道我必须使用访问令牌,但我不知道如何设置它.我试图使用echo我自己的访问令牌和页面的访问令牌,并在post api中使用它,但这不起作用我得到了这个错误:

Uncaught OAuthException: An active access token must be used to query information about the current user.

这是我尝试的代码:

require_once('scripts/facebook.php');
    $config = array('appId' => 'xxx','secret' => 'xxx');

    $params = array('scope'=>'user_likes,publish_actions,email,offline_access,publish_stream,manage_pages');
    $facebook = new Facebook($config);
    $user = $facebook->getUser();
    if($facebook->getUser()) {
    try {

        $user_profile = $facebook->api('/me');
        $access_token = $facebook->getAccessToken();
        //echo "1. ".$access_token;

      } catch(FacebookApiException $e) {
                        $login_url = $facebook->getLoginUrl($params);
                        error_log($e->getType());
                        error_log($e->getMessage());
      }   
    } else {
        $login_url = $facebook->getLoginUrl($params);

    }    

$page_id = "xxxxxxxxxxxxx";
            $page_access_token = "";
            $result = $facebook->api("/me/accounts");
            foreach($result["data"] as $page) {
                if($page["id"] == $page_id) {
                $page_access_token = $page["access_token"];
                //echo '<br>';
                //echo "2. ".$page_access_token;
                break;
                    }
                }


        $args = array(
            'access_token'  => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
            'message'       => stripslashes($image_caption).$animaged_gif,
            'name' => stripslashes($image_caption).$animaged_gif,
            'link' => "http://www.example.com/images.php?i=".$image_name,
            'picture' => "http://www.example.com/thumbnails/".$image_name.".png",
            'actions' => array(
            'name' => 'See Pic',
            'link' => "http://www.example.com/images.php?i=".$image_name
            )

        );
       $post = $facebook->api("/$page_id/feed","post",$args);

正如您所看到的那样,我尝试使用我在回显自己的访问令牌时获得的实际访问令牌.但那没用.我还使用了页面的访问令牌,但这也没有用.你能告诉我这里缺少什么或者这样做的正确方法是什么？在我做了一些进一步的搜索后,我遇到了setAccessToken,$page_info = $fb->api("/".$sInfo['pageId']."?fields=access_token");但是如何使用它们的资源非常有限.我甚至不确定这些是否适合这个问题.我需要知道的是我需要使用哪个访问令牌以及设置它的适当代码是什么？

这是你如何做到的:

获得短暂的访问权限.
扩展它.
获取一个长期访问的页面.(无所谓,这里我们每次都要获取新的accessstoken.不那么复杂,可靠.)

以为我会使用算法,而是添加所有可能的代码和文档,因为这可能对其他人有所帮助.

获取短期访问令牌并扩展它:

fetchtoken.php

<?php

//read more : https://developers.facebook.com/docs/howtos/login/server-side-login/
session_start();
$app_id = "xxxxxxxxxxxxxx";
$app_secret = "xxxxxxxxxxxxxxxx";
$my_url = "www.stackoverflow.com/";  // redirect url

$code = $_REQUEST["code"];

if(empty($code)) {
    // Redirect to Login Dialog
    $_SESSION['state'] = md5(uniqid(rand(), TRUE)); // CSRF protection
    $dialog_url = "https://www.facebook.com/dialog/oauth?client_id=" 
       . $app_id . "&redirect_uri=" . urlencode($my_url) . "&state="
       . $_SESSION['state'] . "&scope=publish_stream,read_friendlists,email";


    echo("<script> top.location.href='" . $dialog_url . "'</script>");
}
if($_SESSION['state'] && ($_SESSION['state'] === $_REQUEST['state'])) {
    $token_url = "https://graph.facebook.com/oauth/access_token?"
       . "client_id=" . $app_id . "&redirect_uri=" . urlencode($my_url)
       . "&client_secret=" . $app_secret . "&code=" . $code;

     $response = file_get_contents($token_url);
     $params = null;
     parse_str($response, $params);
     $longtoken=$params['access_token'];


//save it to database   
} 
?>

因此,您现在可以在数据库,文本文件或其他任何内容中使用长期存在的accessstoken.

cronjob.php

<?
require_once('scripts/facebook.php');
// Pull access token from the file/db
$access_token = "access token from file or db";
$facebook->setAccessToken($access_token); // sets our access token as the access token when we call something using the SDK, which we are going to do now.

$config = array('appId' => 'xxx','secret' => 'xxx');

$params = array('scope'=>'user_likes,publish_actions,email,publish_stream,manage_pages');
$facebook = new Facebook($config);
$user = $facebook->getUser();
if($facebook->getUser()) {
    try {

        $user_profile = $facebook->api('/me');
    } catch(FacebookApiException $e) {
        $login_url = $facebook->getLoginUrl($params);
        error_log($e->getType());
        error_log($e->getMessage());
    }   
}
else {
    $login_url = $facebook->getLoginUrl($params);
}    

$page_id = "xxxxxxxxxxxxx";
$page_access_token = "";
$result = $facebook->api("/me/accounts");
foreach($result["data"] as $page) {
    if($page["id"] == $page_id) {
        $page_access_token = $page["access_token"];
        //echo '<br>';
        //echo "2. ".$page_access_token;
        break;
    }
}

$args = array(
    'access_token'  => $page_access_token,
    'message'       => stripslashes($image_caption).$animaged_gif,
    'name' => stripslashes($image_caption).$animaged_gif,
    'link' => "http://www.example.com/images.php?i=".$image_name,
    'picture' => "http://www.example.com/thumbnails/".$image_name.".png",
    'actions' => array(
            'name' => 'See Pic',
             'link' => "http://www.example.com/images.php?i=".$image_name
    )
);
$post = $facebook->api("/$page_id/feed","post",$args);
?>

确保您没有在脚本中再次获取access_token(用户访问令牌/ $ access_token).

此外,access_token在$args这页面访问令牌应该由$ page_access_token变量不能手动插入,和.

其offline_access在范围确实没有什么比他们展示在他们的数据可以被访问,可以不用该通知反正做的任何时间权限对话框.

只要您在开始时访问fetch.php一次,并且每60天手动访问一次,这应该有效.

让我知道.
