我是Facebook SDK for PHP的新手。我在这里有一个非常基本的问题（这个答案没有帮助）：我目前登录到我的 Facebook 个人资料，但是getUser()没有返回任何内容。为什么？

require_once("vendor/facebook-php-sdk/src/facebook.php");

class Controller_Test extends Controller {
    public function action_me()
        {
            $config = array();
            $config['appId'] = 'dfjq454...';
            $config['secret'] = 'adfw424...';
            $config['fileUpload'] = false;
            $facebook = new Facebook($config);  
            $user = $facebook->getUser();

            // Returns '0'
            echo "Me: ".$user;
            // ...

编辑1：

我尝试在 bootstrap.php 中取消注释这一行，但它不起作用'auth' => MODPATH.'auth', // Basic authentication

编辑 2： 当我运行以下代码时

$user_profile = $facebook->api('/me');
        echo "My Profile: ".$user_profile;

我收到这个错误

必须使用活动访问令牌来查询有关当前用户的信息。

来自Facebook 开发者文档：

注意：配置为本机/桌面应用程序的应用程序将无法进行需要应用程序 access_token 的 API 调用。

转到设置→高级，并将其更改为Web：

这是此问题的最常见原因，将其更改为Web应该可以解决它。

如果不是这种情况，则可能是 PHP SDK 的问题，它依赖于$_REQUEST来自服务器的超全局数组，由于默认php.ini设置已更改，该数组在 PHP 5.4.x 中已更改。一种解决方法是模仿with和超全局数组中的使用。 source $_REQUESTbase_facebook.php$_GET$_POST$_COOKIE

在您的 中找到以下代码base_facebook.php：

<?php

protected function getCode() {
    if (isset($_REQUEST['code'])) {
        if ($this->state !== null &&
                isset($_REQUEST['state']) &&
                $this->state === $_REQUEST['state']) {

            // CSRF state has done its job, so clear it
            $this->state = null;
            $this->clearPersistentData('state');
            return $_REQUEST['code'];
        } else {
            self::errorLog('CSRF state token does not match one provided.');
            return false;
        }
    }

    return false;
}

?>

将其更改为：

<?php

protected function getCode() {
    $server_info = array_merge($_GET, $_POST, $_COOKIE);

    if (isset($server_info['code'])) {
        if ($this->state !== null &&
                isset($server_info['state']) &&
                $this->state === $server_info['state']) {

            // CSRF state has done its job, so clear it
            $this->state = null;
            $this->clearPersistentData('state');
            return $server_info['code'];
        } else {
            self::errorLog('CSRF state token does not match one provided.');
            return false;
        }
    }

    return false;
}

?>

看到不同。

I was stuck up with similar issue, here is the solution that may help you.

 $facebook = new Facebook(array(
    'appId'  => 'xxxx',
    'secret' => 'xxxxx',
    "redirect_uri" => "set the uri to point to the same page"
 ));

$user = $facebook->getUser();

if($user)
{
//your task
} else {
header('location:'. $facebook->getLoginUrl());

}

$user = $facebook->getUser();

if($user)
{
 //your task
} else {
header('location:'. $facebook->getLoginUrl());

}
