Question

我使用以下代码获取用户的帖子，APP_ID和APP_SECRET替换为相应的字段。

<?php
session_start();
require_once __DIR__ . '/src/Facebook/autoload.php';

$fb = new Facebook\Facebook([
'app_id' => 'APP_ID',
'app_secret' => 'APP_SECRET',
'default_graph_version' => 'v2.5',]);

$helper = $fb->getCanvasHelper();

$permissions = ['user_posts']; // optionnal

try {
if (isset($_SESSION['facebook_access_token'])) {
$accessToken = $_SESSION['facebook_access_token'];
} else {
    $accessToken = $helper->getAccessToken();
}
} catch(Facebook\Exceptions\FacebookResponseException $e) {
// When Graph returns an error
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
// When validation fails or other local issues
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}

if (isset($accessToken)) {

if (isset($_SESSION['facebook_access_token'])) {
    $fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
} else {
    $_SESSION['facebook_access_token'] = (string) $accessToken;

    // OAuth 2.0 client handler
    $oAuth2Client = $fb->getOAuth2Client();

    // Exchanges a short-lived access token for a long-lived one
    $longLivedAccessToken = $oAuth2Client->getLongLivedAccessToken($_SESSION['facebook_access_token']);

    $_SESSION['facebook_access_token'] = (string) $longLivedAccessToken;

    $fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
}

// validating the access token
try {
    $request = $fb->get('/me');
} catch(Facebook\Exceptions\FacebookResponseException $e) {
    // When Graph returns an error
    if ($e->getCode() == 190) {
        unset($_SESSION['facebook_access_token']);
        $helper = $fb->getRedirectLoginHelper();
        $loginUrl = $helper->getLoginUrl('https://apps.facebook.com/APP_NAMESPACE/', $permissions);
        echo "<script>window.top.location.href='".$loginUrl."'</script>";
        exit;
    }
} catch(Facebook\Exceptions\FacebookSDKException $e) {
    // When validation fails or other local issues
    echo 'Facebook SDK returned an error: ' . $e->getMessage();
    exit;
}

// getting all posts published by user
try {
    $posts_request = $fb->get('/me/posts?limit=500');
} catch(Facebook\Exceptions\FacebookResponseException $e) {
    // When Graph returns an error
    echo 'Graph returned an error: ' . $e->getMessage();
    exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
    // When validation fails or other local issues
    echo 'Facebook SDK returned an error: ' . $e->getMessage();
    exit;
}

$total_posts = array();
$posts_response = $posts_request->getGraphEdge();
if($fb->next($posts_response)) {
    $response_array = $posts_response->asArray();
    $total_posts = array_merge($total_posts, $response_array);
    while ($posts_response = $fb->next($posts_response)) {  
        $response_array = $posts_response->asArray();
        $total_posts = array_merge($total_posts, $response_array);  
    }
    print_r($total_posts);
} else {
    $posts_response = $posts_request->getGraphEdge()->asArray();
    print_r($posts_response);
}

// Now you can redirect to another page and use the access token from $_SESSION['facebook_access_token']
} else {
 $helper = $fb->getRedirectLoginHelper();
 $loginUrl = $helper->getLoginUrl('https://apps.facebook.com/APP_NAMESPACE/', $permissions);
 echo "<script>window.top.location.href='".$loginUrl."'</script>";

}

当我在命令行（php post.php）上本地运行它时，我得到以下内容：

<script>window.top.location.href='https://www.facebook.com/v2.5/dialog/oauth?client_id=843019182480437&state=bb8b088f64641baed7d1e4de734ad19b&response_type=code&sdk=php-sdk-5.1.2&redirect_uri=https%3A%2F%2Fapps.facebook.com%2FAPP_NAMESPACE%2F&scope=user_posts

这意味着语法正确。当我转到链接时，我得到Facebook的以下通知：

Given URL is not allowed by the Application configuration: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.

我已将网站网址设置为适当的值。当我尝试从我的服务器访问post.php时，我收到内部服务器错误。

有没有其他人经历过这个？
