Ask for help - Nginx module - how to add a module to decode/modify parameter on HTTP request

[Baok Liang]

Hello,

We are new on Nginx module development. Currently we encounter an issue as below. Could you please help to check? Thanks in advanced.

Scenario:
add a module to decode/modify parameter on HTTP request. Then pass the updated HTTP request to PHP to be handled as normal.

Question:
How to modify nginx.conf and how to decode/modify HTTP request?
Currently, all examples about nginx module I got are nginx module handle HTTP request and then provide response to client directly.


nginx.conf
...
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
# NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

# With php5-cgi alone:
fastcgi_pass 127.0.0.1:9000;
# With php5-fpm:
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}

You can use the ngx_lua module for this:

https://github.com/openresty/lua-nginx-module#readme

Basically you'll find the ngx.req.get_body_data() and
ngx.req.set_body_data() handy :)

you might want to check the lua-module http://wiki.nginx.org/HttpLuaModule

there are a lot of different functions to manipulate each part/phase
of a request; i understand that is, what you want?

if you already use openresty than you'll find lua included in your nginx.

Please do not post the same question repeatedly. This is very annoying
and impolite.

You also seem to ignore both mex's and my responses to your earlier
posts. For example,

https://groups.google.com/d/msg/openresty-en/bVH-eDA8wYo/W2VByofkWAEJ

If you keep doing this, I'll have no choice but ban you from this list.
