我正在设置一个基于WP的应用程序,由于facebook页面选项卡和手机的一些限制,我试图设置一个重定向,将页面定向到设备,如果通过page\\u选项卡、direct url或canvas访问页面。
ie。
重定向URL是为所访问的特定页面在自定义字段中设置的,如果未设置,则假定在以一种或另一种方式重定向之前确定它是什么帖子类型。如果它是通过手机访问的,它应该重定向,但正常运行页面。
如果直接通过浏览器访问页面,则应重定向到自定义字段url集(如果posttype为page),如果posttype为“course”,则应重定向到特定的画布应用程序。。。
如果访问(使用appdata设置/通过facebook页面选项卡),它应该显示为正常。。。
由于重定向,在发送任何其他标头之前,它需要在标头中(?)
问题是。。。如何才能高效地重定向直接访问URL的用户,即://fu。viralapps。否/tamtam至facebook版本//www.facebook。com/TheTamTampage/App123123123。但仅当通过台式机/笔记本电脑访问该网站时。而不是通过智能手机/平板电脑。
每个页面要重定向到的页面都不同(重定向url在WP页面中设置为自定义字段)//fu。viralapps。否/tamtam=>//www.facebook。com/TheTamTampage/App123123123//fu。viralapps。否/tamtamtam2=>//www.facebook。com/TheTamTampage/App232323232//fu。viralapps。否/tamtam3=>//www.facebook。com/TheTamTampage/App34343434
facebookpage选项卡/应用程序不会重定向其iframed页面,因为它包含一个通过facebook自动签名的请求。
这是我目前的代码。。。(添加了一些调试回音)
<?php
$signed_request = $_REQUEST[\'signed_request\']; // Get the POST signed_request variable.
if(isset($signed_request)) // Determine if signed_request is blank.

$pre = explode(\'.\',$signed_request); // Get the part of the signed_request we need.
$json = base64_decode($pre[\'1\']); // Base64 Decode signed_request making it JSON.
$obj = json_decode($json,true); // Split the JSON into arrays.
$page = $obj[\'page\']; // Get the page array. It has a sub array.

// RUN PAGE AS PLANNED!
