How to modify a POST arg within Nginx?

elvis.deng

Hi all,

I want to modify a POST value in Nginx and then put it back (don’t change its original data flow).

Does any existing module do the similar work?

Best wishes,

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 :)
