post handler

Provide a hook before receiving the body. Pre-process the header before receiving the body.

install

git clone https://github.com/aiwhj/post_handler.git
cd post_handler
phpize
configure
make && make install

config

[post_handler]
;configuration for php post_handler module
extension = post_handler.so

;whether to open 
;1-Y 0-N(Default)
post_handler.enable = 0

;handler type
;1-file(Default) 2-Command Line
post_handler.handler_type = 1

;The full path to the file or the command line
post_handler.handler = /work/post_handler/handler.php
;post_handler.handler="if (!isset($_SERVER['HTTP_HANDLER']) || $_SERVER['HTTP_HANDLER'] != 'post') { echo 'do not receive the body' . PHP_EOL; exit(1); }"

notice

works only when Content-Type = multipart/form-data
the exit status must be Integer.
when exit status is greater than 0, the post handler stops receiving the body and stops executing your real code.
you have to manually print some strings to tell the Web Server, otherwise HTTP Code will be 502.

example

<?php
/**
 * handler.php
 * 
 * When the HTTP_HANDLER in the header is not equal to the 'post', do not receive the body.
 * Global variables only $_SERVER
 */

if (!isset($_SERVER['HTTP_HANDLER']) || $_SERVER['HTTP_HANDLER'] != 'post') {
    echo 'do not receive the body' . PHP_EOL;
    exit(1);
}
