我有两个晚上没有睡觉试图解决这个问题,但今天我感到失败了,我来找你帮忙。
我在使用High Sierra的MacOS上,在使用MAMP的localhost上。
的index.php
<?php
session_start();
require_once 'vendor/autoload.php';
$fb = new Facebook\Facebook([
'app_id' => 'APP_ID',
'app_secret' => 'APP_SECRET',
'default_graph_version' => 'v2.10',
]);
$helper = $fb->getRedirectLoginHelper();
$permissions = ['email'];
$loginUrl = $helper->getLoginUrl('http://localhost/facebookphp/fb-callback.php', $permissions);
echo '<a href="' . htmlspecialchars($loginUrl) . '">Log in with Facebook!</a>';
?>
FB-callback.php
<?php
session_start();
require_once 'vendor/autoload.php';
$fb = new Facebook\Facebook([
'app_id' => 'APP_ID',
'app_secret' => 'APP_SECRET',

]);
$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)
$tokenMetadata->validateAppId('APP_ID'); // Replace {app-id} with your app id
// If you know the user ID this access token belongs to, you can validate it here
//$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: http://localhost/members.php');

尝试在 fb-callback.php 文件中修改此内容
替换
$accessToken = $helper->getAccessToken();
的
$accessToken = $helper->getAccessToken("http://localhost/facebookphp/fb-callback.php");
在方法getAccessToken
中添加相同的有效OAuth重定向URI字段
