echo_read_request_body in content phase about echo-nginx-module HOT 5 CLOSED

@chirkin Please use the ngx_lua module instead. It is just a single line for your use case:

rewrite_by_lua 'ngx.req.read_body()';

Simple enough. Although ngx_lua is way more powerful than just that.

@agentzh Thank you, it is really more powerful. I think the performance is not much affected.

@agentzh I found that this solution has drawbacks. In particular postgres_escape function is called before than the ngx.req.read_body() processed. I need to protect sql query. Do you have any solutions?

@chirkin Well, just use the ndk.set_var.set_quote_pgsql_str() API function in Lua to do the escaping. You'll need the ngx_set_misc module too. See
