【问题描述】：
我被困住了... 一切看起来都正确，但它不起作用。尝试使用我的应用程序在 facebook 开发人员的调试访问令牌，它工作得很好，所以它不是代码恢复的问题。
index.php
<?php
session_start();
/******Improting Facebook API Files**************/
require_once 'src/Facebook/autoload.php';
require_once 'credentials.php';
/******Facebook API Connection With My APP**************/
$fb = new Facebook\Facebook([
'app_id' => $appid,
'app_secret' => $appsecret,
'default_graph_version' => 'v2.3'
]);
/******Initializing The Login**************/
$helper = $fb->getRedirectLoginHelper();
$permissions = ['email', 'public_profile']; // optional
#echo '<script type="text/javascript">alert("'.$incommingurl.'");</script>';
#echo '<script type="text/javascript">alert("'.$permissions.'");</script>';
#var_dump($permissions);
#var_dump($helper);
$loginUrl = $helper->getLoginUrl($incommingurl, $permissions);
/******Printing The Login URL**************/
echo'<a href="' . $loginUrl . '" class="facebookLoginButton" title="Login With Facebook">Sign in with Facebook</a>';
?>
token.php
<?php
session_start();
/******Improting Facebook API Files**************/
require_once 'src/Facebook/autoload.php';
require_once 'credentials.php';
/******Facebook API Connection With My APP**************/
$fb = new Facebook\Facebook([
'app_id' => $appid,
'app_secret' => $appsecret,
'default_graph_version' => 'v2.3'
]);
$helper = $fb->getRedirectLoginHelper();
/******Getting Token From Facebook**************/
var_dump($helper);
try {
echo '<script type="text/javascript"> alert("1235")</script>';
$accessToken = $helper->getAccessToken();
var_dump($accessToken);
} 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: ' . $e->getMessage();
exit;
}
/******Storing Token In Sessions For Further Use**************/
if (isset($accessToken)) {
$_SESSION['token'] = (string) $accessToken;
echo $_SESSION['token'];
header('location: collectUserData.php');
}
else{
//echo "err";
header('location: index.php');
}
?>
使用有效令牌设置 $accesstoken 代码可以正常工作，因此我没有获得访问令牌。我可以转储 $helper，结果是：
object(Facebook\Helpers\FacebookRedirectLoginHelper)#7 (4) { ["oAuth2Client":protected]=> object(Facebook\Authentication\OAuth2Client)#8 (4) { ["app":protected]=> object(Facebook\FacebookApp)#3 (2) { ["id":protected]=> string(15) "xxxxxxxxxxxx" ["secret":protected]=> string(32) "xxxxxxxxxxxxxxxxxx" } ["client":protected]=> object(Facebook\FacebookClient)#4 (2) { ["enableBetaMode":protected]=> bool(false) ["httpClientHandler":protected]=> object(Facebook\HttpClients\FacebookCurlHttpClient)#5 (4) { ["curlErrorMessage":protected]=> string(0) "" ["curlErrorCode":protected]=> int(0) ["rawResponse":protected]=> NULL ["facebookCurl":protected]=> object(Facebook\HttpClients\FacebookCurl)#6 (1) { ["curl":protected]=> NULL } } } ["graphVersion":protected]=> string(4) "v2.3" ["lastRequest":protected]=> NULL } ["urlDetectionHandler":protected]=> object(Facebook\Url\FacebookUrlDetectionHandler)#10 (0) { } ["persistentDataHandler":protected]=> object(Facebook\PersistentData\FacebookSessionPersistentDataHandler)#9 (1) { ["sessionPrefix":protected]=> string(6) "FBRLH_" } ["pseudoRandomStringGenerator":protected]=> object(Facebook\PseudoRandomString\McryptPseudoRandomStringGenerator)#11 (0) { } }
但是 $accessToken = $helper->getAccessToken(); 没有结果 var_dump($accessToken);
有人可以帮忙吗？
最好的问候和新年快乐:-)
