认证后如何重定向到canvas页面？
我是菜鸟，我需要一些帮助。我刚刚创建了第一个简单的应用程序，但遇到了问题。如果用户第一次打开此应用程序并单击身份验证页面上的“允许”按钮，它将跳转到存储我的应用程序的站点，而不是应在 iframe 中显示的画布页面。
该应用程序的网址是 https://apps.facebook.com/kpxyapp/
（我删除了 appid 并来自下面的代码的秘密。）
如果您能提供帮助，我将不胜感激。谢谢。
<?php
require 'src/facebook.php';
$facebook = new Facebook(array(
'appId' => '',
'secret' => '',
));
$user = $facebook->getUser();
if ($user) {
$me = $facebook->api('/me');
echo "Hello my name is : {$me['name']}";
} else {
$loginUrl = $facebook->getLoginUrl();
echo "<script>top.location.href=\"{$loginUrl}\"</script>";
}
?>
I am a noob and I need some help. I just created my first simple app and I ran into an problem. If a user opens this app for the first time and clicks on the 'allow' button on the authentication page, it jumps to the site where my app is stored and not to the canvas page where it should be displayed in iframe.
The app's url is https://apps.facebook.com/kpxyapp/
(I removed the appid and secret from the code below.)
I would be grateful if you could help. Thanks.
<?php
require 'src/facebook.php';
$facebook = new Facebook(array(
'appId' => '',
'secret' => '',
));
$user = $facebook->getUser();
if ($user) {
$me = $facebook->api('/me');
echo "Hello my name is : {$me['name']}";
} else {
$loginUrl = $facebook->getLoginUrl();
echo "<script>top.location.href=\"{$loginUrl}\"</script>";
}
?>
