【中文标题】使用 Facebook PHP SDK API 的意外应用程序 ID【英文标题】:Unexpected App Id using Facebook PHP SDK API 【发布时间】:2016-01-10 11:14:44 【问题描述】: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();

require_once '/home/mywebsite/lab/vendor/autoload.php';
$fb = new Facebook\Facebook([
'app_id' => '999999999999999',

]);
$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,但出现以下错误:

我该如何解决?
我注意到问题出在:
$tokenMetadata->validateAppId($config['app_id']);
【问题讨论】:
【参考方案1】:除了其他答案之外,您还可以真正使用 $config 变量。在 Facebook 对象初始化之前声明它:
$config =
[
'app_id' => '999999999999999',
'app_secret' => 'removed',
'default_graph_version' => 'v2.4',
];
$fb = new Facebook\Facebook([
'app_id' => '999999999999999',
'app_secret' => 'removed',
'default_graph_version' => 'v2.4',
]);
//other stuffs
// Validation (these will throw FacebookSDKException's when they fail)
$tokenMetadata->validateAppId($config['app_id']);
我怀疑由于某些原因 Facebook 错误地删除了示例中 $config 的声明:
https://github.com/facebookarchive/php-graph-sdk/blob/5.x/docs/examples/facebook_login.md
【讨论】:
【参考方案2】:当您也将 APPID 分配为这样的整数时,您将收到 Unexpected App Id 错误。
$tokenMetadata->validateAppId(1034645623719);
您必须像这样将您的 APPID 分配为字符串(在引号内)
$tokenMetadata->validateAppId('1034645623719');
【讨论】:
为什么是 Facebook,为什么?! 是的,今天仍然如此。 Facebook 对象的所有 ID 都是字符串,但我从未在平台上看到任何非数字 ID...此外,他们称它们为“数字字符串”:developers.facebook.com/docs/graph-api/reference/application【参考方案3】:变量$config['app_id']
未定义,直接使用app id:
$tokenMetadata->validateAppId(YOU_APP_ID);
