Safari和php会话无法在facebook iframe中运行 [英] Safari and php sessions not working in facebook iframe

问题描述

我的问题是让我的Facebook应用在Safari上工作。

I'm having a problem to make my facebook app working on Safari.

这个问题与PHP会话变量有关。

The issue is related to the PHP session variables.

我知道Safari在处理跨域会话（在iframe内部）时遇到问题，我找到了大约2种类型的解决方案：

I am aware that Safari has a problem dealing with cross domain sessions (inside an iframe) and i found around 2 types of solutions:

1. 设置p3p标头：我已经尝试了很多p3p标头，但没有一个工作[例如：标头（'P3P：CP =NOI ADM DEV COM NAV）我们的STP'）; ]。


2. 使用javascript将帖子发送到iframe。这会创建交互，会话应该有效。但事实是我不控制iframe容器，因为那是facebook。

有没有人知道替代解决方案？

Does anyone know an alternative solution?

谢谢！

推荐答案

我迟到了，但可能会有所帮助别人正在查找这个问题。

I am late to this but it may well help someone else looking up this problem.

我能做的唯一方法就是从我的iframe中检测safari并在我可以设置会话cookie的时候重定向到另一个页面 - 然后重定向回来。

The only method I could make work was to detect safari from inside my iframe and redirect to another page momentarily where I could set my session cookie - then redirect back.

<?php
// sort out ie with the below header
header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');
session_start();
$_SESSION = array();

// if Safari and no cookies have been set yet, take me to another page to set a session cookie
if (strpos($_SERVER['HTTP_USER_AGENT'], 'Safari') && !strpos($_SERVER['HTTP_USER_AGENT'], 'Chrome')) {
    if (count($_COOKIE) === 0) {
     echo '<script> 
     top.location = "http://www.domain.com/setcookie.php";
     </script>';
    }
}
?>

然后来自setcookie.php

Then from setcookie.php

<?php
//inside setcookie.php
header('P3P: CP="CAO PSA OUR"');
session_start();
$_SESSION = array();

echo 
'<script>
top.location = "http://www.backtooriginaldomain.com"; 
</script>';
?>

它有点蹩脚，但确实有效并且不会干扰其他浏览器。另一种方法是使用一个弹出窗口，虽然我的safari默认阻止它。

its a bit lame but does work and doesn't interfere with the other browsers. The other method is to use a popup window although my safari had this blocked by default.
