登录与Facebook不断从Facebook

Question

我申请permision确认后重定向“登录与Facebook”在我的网站。

当我点击登录与Facebook ....它重定向至Facebook请求许可。我点击确定。之后，它会同时重定向到Facebook和我的网站。

我下面提供我的代码。任何人都可以帮助我找出重定向错误的位置吗？

这里是我的代码：

的index.php

<?php 
session_start(); 

if ($_SESSION['FBID']): ?>  <!-- After user login --> 

<h1>Hello <?php echo $_SESSION['USERNAME']; ?></h1> 

<li><?php echo $_SESSION['FULLNAME']; ?></li> 

<div><a href="logout.php">Logout</a></div> 

<?php else: ?>  <!-- Before login --> 

Not Connected 
<div><a href="fbconfig.php">Login with Facebook</a></div> 

<?php endif ?> 

fbconfig.php

<?php 
require 'src/facebook.php'; // Include facebook SDK file 
//require 'functions.php'; // Include functions 
$facebook = new Facebook(array(
    'appId' => 'APP_ID', // Facebook App ID 
    'secret' => 'SECRET', // Facebook App Secret 
    'cookie' => true, 
)); 
$user = $facebook->getUser(); 

if ($user) { 
    try { 
    $user_profile = $facebook->api('/me'); 
     $fbid = $user_profile['id'];     // To Get Facebook ID 
     $fbuname = $user_profile['username']; // To Get Facebook Username 
     $fbfullname = $user_profile['name']; // To Get Facebook full name 
     $femail = $user_profile['email']; // To Get Facebook email ID 
    /* ---- Session Variables -----*/ 
     $_SESSION['FBID'] = $fbid;   
     $_SESSION['USERNAME'] = $fbuname; 
      $_SESSION['FULLNAME'] = $fbfullname; 
     $_SESSION['EMAIL'] = $femail; 
    //  checkuser($fbid,$fbuname,$fbfullname,$femail); // To update local DB 
    } catch (FacebookApiException $e) { 
    error_log($e); 
    $user = null; 
    } 
} 
if ($user) { 
    header("Location: index.php"); 
} else { 
$loginUrl = $facebook->getLoginUrl(array(
     'scope'  => 'email', // Permissions to request from the user 
     )); 
header("Location: ".$loginUrl); 
} 
?> 

Answer 1

您需要提供REDIRECT_URL（index.php文件的URL）

if ($user) { 
    header("Location: index.php"); 
} else { 
$loginUrl = $facebook->getLoginUrl(array(
     'scope'  => 'email', // Permissions to request from the user 
     'redirect_uri' => 'URL of index.php' 
     )); 
header("Location: ".$loginUrl); 
} 

一件事，你不应该透露您的APP_ID和app_secret。尽快将其删除。
