使用Facebook PHP SDK API的意外的应用程序ID

Question

这是我的登录脚本:

<?php
// session não são nativas, precisa iniciar.
session_start();
date_default_timezone_set('America/Sao_Paulo');
require_once '/home/mywebsite/lab/vendor/autoload.php';

// por algum motivo não está aceitando a referência via __DIR__
//require_once __DIR__ . '/vendor/autoload.php';

$fb = new Facebook\Facebook([
  'app_id' => '999999999999999',
  'app_secret' => 'removed',
  'default_graph_version' => 'v2.4',
]);

$helper = $fb->getRedirectLoginHelper();

$permissions = ['email']; // Optional permissions
//$loginUrl = $helper->getLoginUrl('https://www.mywebsite.com.br/lab/?secao=meusPedidos', $permissions);
$loginUrl = $helper->getLoginUrl('https://www.mywebsite.com.br/lab/fb-callback.php', $permissions);

echo '<a href="' . htmlspecialchars($loginUrl) . '">Log in with Facebook!</a>';

?>

这是我的回调脚本:

<?php
session_start();
date_default_timezone_set('America/Sao_Paulo');
require_once '/home/mywebsite/lab/vendor/autoload.php';

$fb = new Facebook\Facebook([
  'app_id' => '999999999999999',
  'app_secret' => 'removed',
  'default_graph_version' => 'v2.4',
]); 

$helper = $fb->getRedirectLoginHelper();  

try {  
  $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($accessToken)) {  
  if ($helper->getError()) {  
    header('HTTP/1.0 401 Unauthorized');  
    echo "Error: " . $helper->getError() . "\n";
    echo "Error Code: " . $helper->getErrorCode() . "\n";
    echo "Error Reason: " . $helper->getErrorReason() . "\n";
    echo "Error Description: " . $helper->getErrorDescription() . "\n";
  } else {  
    header('HTTP/1.0 400 Bad Request');  
    echo 'Bad request';  
  }  
  exit;  
}  

// Logged in  
echo '<h3>Access Token</h3>';  
var_dump($accessToken->getValue());  

// The OAuth 2.0 client handler helps us manage access tokens  
$oAuth2Client = $fb->getOAuth2Client();  

// Get the access token metadata from /debug_token  
$tokenMetadata = $oAuth2Client->debugToken($accessToken);  
echo '<h3>Metadata</h3>';  
var_dump($tokenMetadata);  

// Validation (these will throw FacebookSDKException's when they fail)  
$tokenMetadata->validateAppId($config['app_id']);  
// If you know the user ID this access token belongs to, you can validate it here  
// $tokenMetadata->validateUserId('123');  
$tokenMetadata->validateExpiration();   

if (! $accessToken->isLongLived()) {  
  // Exchanges a short-lived access token for a long-lived one  
  try {  
    $accessToken = $oAuth2Client->getLongLivedAccessToken($accessToken);  
  } catch (Facebook\Exceptions\FacebookSDKException $e) {  
    echo "<p>Error getting long-lived access token: " . $helper->getMessage() . "</p>";  
    exit;  
  } 
  echo '<h3>Long-lived</h3>';  
  var_dump($accessToken->getValue());  
}

$_SESSION['fb_access_token'] = (string) $accessToken;  

// User is logged in with a long-lived access token.  
// You can redirect them to a members-only page.  
// header('Location: https://example.com/members.php');
?>

我正在尝试使用FB-PHP-SDK登录,但是出现以下错误:

访问令牌

string(213)"my acess token"元数据

我该如何解决？

我注意到问题在于:

$ tokenMetadata-> validateAppId($配置[ 'APP_ID']);

Answer 1

变量$config['app_id']未定义,直接使用app id:

$tokenMetadata->validateAppId(YOU_APP_ID);

Answer 2

当您将APPID分配为这样的整数时,您将收到Unexpected App Id错误.

$tokenMetadata->validateAppId(1034645623719);

您必须将APPID指定为字符串(在引号内),如下所示

$tokenMetadata->validateAppId('1034645623719');
