Facebook - how to go directly to the request permission dialog with an iframe app?
提问by Scott Szretter
When a user accesses my facebook app via http://apps.facebook.com/myappxxxxx, I want it to immediately show the request permissions fb dialog - like so many others do.
当用户通过http://apps.facebook.com/myappxxxxx访问我的 facebook 应用程序时，我希望它立即显示请求权限 fb 对话框 - 就像许多其他人一样。
I have tried all sorts of things - including php redirect using the getLoginUrl, javascript window location redirect using the same.
我已经尝试了各种各样的事情 - 包括使用 getLoginUrl 的 php 重定向，使用相同的 javascript 窗口位置重定向。
The problem is that it shows a big facebook icon instead of the request permissions. However, if you click on that icon, it in fact goes to the correct request permissions page!
问题是它显示了一个大的 Facebook 图标而不是请求权限。但是，如果您单击该图标，它实际上会转到正确的请求权限页面！
Does anyone know how to redirect to the facebook permissions page properly?
有谁知道如何正确重定向到 Facebook 权限页面？

I had the exact same problem a while ago. Here's a little hack:
不久前我遇到了完全相同的问题。这是一个小技巧：
if(!$me) {
$url = "https://graph.facebook.com/oauth/authorize?"
."client_id=YOUR_APP_ID&"
."redirect_uri=http://apps.facebook.com/APP_SLUG/&"
."scope=user_photos,publish_stream";
echo "<script language=javascript>window.open('$url', '_parent', '')</script>";
} else {
your code...
}
How it looks in my code (a bit dirty, I had a deadline):
它在我的代码中的样子（有点脏，我有一个截止日期）：
require_once 'facebook-php-sdk/src/facebook.php';
$appid = '';
$facebook = new Facebook(array(
'appId' => $appid,
'secret' => '',
'cookie' => true,
));
$session = $facebook->getSession();
$me = null;
if ($session) {
try {
$uid = $facebook->getUser();
$me = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
}
}
if(!$me) {
// here we redirect for authentication:
// This is the code you should be looking at:
$url = "https://graph.facebook.com/oauth/authorize?"
."client_id=$appid&"
."redirect_uri=http://apps.facebook.com/APP_SLUG/&"
."scope=user_photos,publish_stream";
?>

A simple header redirect won't work since it will only redirect your iframe. Javascript is needed to access the _parent window.
简单的标头重定向将不起作用，因为它只会重定向您的 iframe。访问 _parent 窗口需要 Javascript。

Keep in mind that there is a proper way to do this (see answer below) and I do not recommend doing this. But hey, what ever floats your boat...
请记住，有一种正确的方法可以做到这一点（请参阅下面的答案），我不建议这样做。但是，嘿，是什么让你的船漂浮...

Why don't you try the Facebook authenticated referrals? It's the proper solution for such problem. Since it asks Facebook to traps the non-connected users and redirect them directly to the connect page.
你为什么不试试Facebook 认证的推荐？这是解决此类问题的正确方法。因为它要求 Facebook 捕获未连接的用户并将他们直接重定向到连接页面。
This insure that all of the users are connected to your app by default.
这确保默认情况下所有用户都连接到您的应用程序。

Here's another option:
这是另一种选择：
<script>
(function () {
var url = 'your_permission_url';
window.top.location.href = url;
} ());
</script>
回答by MeetM
The url should be from getLoginUrl($PARAMS). It worked for me. In your case,
url 应该来自 getLoginUrl($PARAMS)。它对我有用。在你的情况下，
$PARAMS = array('scope' => 'user_photos,publish_stream',
redirect_uri => 'https://apps.facebook.com/myappxxxxx');
$PARAMS = array('scope' => 'user_photos,publish_stream',
redirect_uri => 'https://apps.facebook.com/myappxxxxx');

When I change the url as below, it worked !!!!!
当我更改如下网址时，它起作用了！！！！
if(!$me) {
$url = "https://www.facebook.com/dialog/oauth?"
."client_id=YOUR_APP_ID&"
."redirect_uri=http://apps.facebook.com/APP_SLUG/&"
."scope=user_photos,publish_stream";
echo "<script language=javascript>window.open('$url', '_parent', '')</script>";
} else {
your code...
}
