Using POST parameters in WordPress functions.php

Question

I need to use get_header action to hook onto into my functions.php, so that I can check if the request is being sent to a proper page, but at that point in time, $_POST is empty, probably because of redirect. Is there a way to somehow pass that info to my function:

add_action('get_header', 'handle_app_post');

与WordPress开发人员交谈后，不可以，由于WordPress中的内部重定向，这是不可能的。
