Php Facebook应用重定向

我制作了一个facebook应用程序，当从

apps.facebook.com/myapp

打开时，它完美地指向我的域的index.php，可以在facebook应用程序窗口中看到，但当我尝试将其重定向到我的注册页面时，问题出现了，它被重定向到我的域，我希望所有页面都能在facebook应用程序窗口中查看。试图使用fb:redirect sdk功能，但网站表示他们将不推荐这些代码

<?php
if(preg_match('/apps.facebook.com/',$_SERVER[HTTP_REFERER])){
    $app_id = '';
    $api_key = '';
    $app_secret = '';
    $canvas_page = 'mydomain/index.php';
    $auth_url = "http://www.facebook.com/dialog/oauth?client_id=".
    $app_id."&redirect_uri=".urlencode($canvas_page)."&scope=email,user_birthday,user_interests,user_about_me";
    $signed_request = $_REQUEST["signed_request"];
    list($encoded_sig, $payload) = explode('.', $signed_request, 2);
    $data = json_decode(base64_decode(strtr($payload,'-_', '+/')), true);
    if (empty($data["user_id"])){
        echo("<script> top.location.href='".$auth_url ."'</script>");
    }else{
        $canvas_page="mydomain/register.php";
        echo ("<script> top.location.href='".$auth_url."'</script>");
    }
}else{
    echo "No facebook";
}
?>

您的$auth\u url不会更改：

$canvas_page="mydomain/register.php";
echo ("<script> top.location.href='".$auth_url."'</script>");

$canvas\u page=“mydomain/register.php”；
echo（“top.location.href=”。$auth_url。””；

$auth url仍然是顶部定义的url，带有
$canvas_page='mydomain/index.php'
 这与
facebook
无关。这是ABC PHP

<?php
$a = "John";
$b = "Hello " . $a;
$a = "Bob";
print $b; // returns: Hello John
$b = "\nHello " . $a;
print $b; // returns: Hello Bob
?>



Live.
你是说window.location=$auth\u url而不是top.location.href='“$auth\u url.”它们是你真正的api秘密吗？不是为什么我要提供我真正的秘密？
