Question

我的英语不好的借口......

我下载并安装了facebook连接API。我被重定向到Facebook但是一旦在facebook上授权我遇到以下错误：＆＃39;我的错误＆＃39;

脚本＆＃39; index.php＆＃39;

<?php


      require_once __DIR__ . '/facebook_api/autoload.php';
$fb = new Facebook\Facebook([
  'app_id' => '88xxxx29',
  'app_secret' => 'xxxxxxxxxx',
  'default_graph_version' => 'v2.2',
  ]);



      $helper = $fb->getRedirectLoginHelper();
$permissions = ['email', 'user_location', 'user_about_me', 'user_birthday', 'user_actions.books']; // optional
$loginUrl = $helper->getLoginUrl('https://www.mywebsite.fr/fb-login-callback.php', $permissions);

echo '<a href="' . $loginUrl . '">Connexion</a>';

      ?>

脚本＆＃39; fb-login-callback.php＆＃39;

<?php
session_save_path("sessions/");
session_start();
require_once __DIR__ . '/facebook_api/autoload.php';

$fb = new Facebook\Facebook([
  'app_id' => '88xxxx29',
  'app_secret' => ‘xxxxxxxxxx',
  'default_graph_version' => 'v2.2',
  ]);

$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>\n\n";
    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');

?>

返回错误： Acces令牌元数据包含意外的应用ID。

但是脚本中指定的id是正确的......

Answer 1

您尝试访问$ config ['app_id']变量，但您尚未定义。试试这个：

 $config =[
  'app_id' => '88xxxx29',
  'app_secret' => ‘xxxxxxxxxx',
  'default_graph_version' => 'v2.2',
  ];
$fb = new Facebook\Facebook ($config );

Facebook api返回错误
