如何将照片作为 Facebook 页面本身上传到 Facebook 页面的时间线，而不是上传到用户提要

Question

好的，所以下面的鳕鱼基本上可以正常工作，当这条线是这样的：

$post_url = '/'.$userPageId.'/feed';

这成功发布到 Facebook 页面时间轴。但是我想上传一张照片，当我把这行改成

$post_url = '/'.$userPageId.'/photos';

它发布照片...但它发布到用户供稿，而不是作为 Facebook 页面。

我希望这可以将照片发布到 Facebook 页面时间轴

[config.php]

<?php
include_once("inc/facebook.php");

##################################
//Call Facebook API

// Required facebook permissions
$fbPermissions = 'publish_stream,manage_pages,photo_upload';

$facebook = new Facebook(array(
  'appId'  => $appId,
  'secret' => $appSecret,
'fileUpload' => true,
'cookie' => true  
));

$fbuser = $facebook->getUser();
?>

[进程.php]

<?php
include_once("config.php");

if($_POST)
{
    //Post variables we received from user
    $userPageId         = $_POST["userpages"];
    $userMessage         = $_POST["message"];

    if(strlen($userMessage)<1) 
    {
            //message is empty
            $userMessage = 'No message was entered!';
    }

    //HTTP POST request to PAGE_ID/feed with the publish_stream
    $post_url = '/'.$userPageId.'/photos';

    //posts message on page statues 
    $msg_body = array(
        'source' => '@' . 'test.jpg',                   
        'message' => "yo yo yo",
    );

    if ($fbuser) {
        try {
            $postResult = $facebook->api($post_url, 'post', $msg_body );
        } catch (FacebookApiException $e) {
            echo $e->getMessage();
        }
    } else {
        $loginUrl = $facebook->getLoginUrl(
            array('redirect_uri'=>$homeurl,'scope'=>$fbPermissions)
        );
        header('Location: ' . $loginUrl);
    }

    //Show sucess message
    if($postResult)

[index.php]（用于登录）

<?php

            .$fbuser.')';
        $postResults = $facebook->api(
            array( 'method' => 'fql.query', 'query' => $fql_query )
        );
    } catch (FacebookApiException $e) {

    $fbuser = null;
}

if($fbuser && empty($postResults))
{
    /*
    if user is logged in but FQL is not returning any pages, we need to make
    sure user does have a page OR "manage_pages" permissions isn't granted yet
    by the user. Let's give user an option to grant permission again.
    */
    $loginUrl = $facebook->getLoginUrl(
        array('redirect_uri'=>$homeurl,'scope'=>$fbPermissions)
    );
    echo '<br />Could not get your page details!';
    echo '<br /><a href="'.$loginUrl.'">Click here to try again!</a>'; 
}
elseif ($fbuser && !empty($postResults))
{
    //Everything looks good, show message form.
}
?>

Answer 1

如果您想充当 Facebook 主页并上传照片，您需要：

1. 成为 Facebook 页面的管理员
2. 获得授权时至少有以下范围：'manage_pages'、'photo_upload'
3. 访问令牌作为 Facebook 页面，而不是作为管理员用户

您可以通过调用Open Graph API 来获取您作为管理员的 Facebook 页面的访问令牌：

$accounts = $facebook->api('/me/accounts','GET');

为了获取访问令牌和更多信息，您需要“manage_pages”权限。

获得访问令牌后，您需要使用它并使用它重新初始化客户端。然后，您基本上可以充当它，并张贴照片。希望这足以让你开始。您的代码看起来已设置为能够将照片上传到您想要的位置。这完全是访问令牌的问题。

编辑：

您可以使用setAccessToken 使用PHP SDK 设置访问令牌：

// Set a new access token, by first getting it via means other than the SDK
$facebook->setAccessToken($new_access_token);
