APP在redirect_url上显示空白页面

发布于 2024-12-25 21:57:14 字数 3787 浏览 1 评论 0原文

我有一个 Facebook PHP SDK 应用程序处于开发阶段，但我陷入了困境...... 应用程序的逻辑是这样的：

首先用户必须喜欢该页面（应用程序就在此）//效果很好:) 之后是权限请求如果授予权限：app_data 变量将被传递，用户会收到图片。

app_data 变量是必需的，因为如果用户在再次授予权限后单击该应用程序，它会自动获取新图片。而 app_data 则不然。

我的问题是这个链接：

    $params = array(
  scope => 'publish_stream,user_photos',
  redirect_uri => 'http://www.facebook.com/XXXXX?sk=app_YYYYYY&app_data=1'
    );

<a href="<?php echo $facebook->getLoginUrl($params); ?>">Accept</a>

如果我点击它，应用程序会显示空白页面，并且什么也没有发生...:( 在直接调用时，该应用程序运行时没有任何错误。

有人可以帮我吗？

// 对不起我的英语...

谢谢！

整个index.php是：

I have a Facebook PHP SDK APP in development phase and i'm stuck on something...
The logic of the APP is this:

first the user have to like the page (app is on this) // works very well :)
after that comes the permissions request
if permission is granted: the app_data variable is pass through and the user recieves a picture.

app_data variable is necessary because, if the user clicks the app after permission granted again, it gets new picture automaticly. with the app_data don't.

my problem is this link:

    $params = array(
  scope => 'publish_stream,user_photos',
  redirect_uri => 'http://www.facebook.com/XXXXX?sk=app_YYYYYY&app_data=1'
    );

<a href="<?php echo $facebook->getLoginUrl($params); ?>">Accept</a>

If i click on it, the app shows blank page, and nothing happening... :(
On direct call, that app runs without any error.

Can someone help me out?

// sorry for my english...

Thank you!

当我深入研究 Facebook 应用程序的世界时，我曾经遇到过这种情况。

我最终所做的是对于我的 redirect_uri 我在我的域上使用了一个页面，例如 https://domain.com/facebook/redirect.php 并在redirect.php中我会有：

// user didn't give app permissions
if (isset($_GET['error_reason']))
{
    header( 'Location: http://www.facebook.com/FANPAGE' ) ;
}
else 
{
    header( 'Location: http://www.facebook.com/XXXXX?sk=app_YYYYYY' ) ;
}

I've had this before when I was delving into the world of Facebook apps.

What I eventually done was for my redirect_uri I used a page on my domain, e.g. https://domain.com/facebook/redirect.php and in redirect.php I would have:

// user didn't give app permissions
if (isset($_GET['error_reason']))
{
    header( 'Location: http://www.facebook.com/FANPAGE' ) ;
}
else 
{
    header( 'Location: http://www.facebook.com/XXXXX?sk=app_YYYYYY' ) ;
}
