php - 商店 Facebook 应用引荐来源网址

Question

我有一些 Facebook 广告和外部广告指向位于页面选项卡上的应用。

当我的应用存储一些用户信息时，我还想记录哪个广告通过某些标识符将他们引至应用。

我知道 $_SERVER['HTTP_REFERER'] 在大多数情况下是不可靠的，并且任何作为查询字符串传递的参数(http://www.facebook.com/pages/Test -Page/21814976xxxxxxx?sk=app_25966185xxxxxxx&referrer=advert_1) 不要坚持。

有什么方法可以准确确定用户如何访问我的 iframed Facebook 应用程序？

转储应用程序上的所有 HTTP 请求 header :

Answer 1

您可以使用 app_data 参数将其他数据传递到在 Page Tab 中工作的应用程序

In addition, your application will also receive a string parameter called app_data as part of signed_request if an app_data parameter was set in the original query string in the URL your tab is loaded on. For the Shop Now link above, that could look like this: "http://www.facebook.com/YourPage?v=app_1234567890&app_data=any_string_here". You can use that to customize the content you render if you control the generation of the link.
