Capture full request/response body logging in nginx configured in reverse proxy mode reports nginx: [emerg] unknown directive "log_by_lua_block"

December 18, 2023 11:56AM
Hi,

I am running nginx version: nginx/1.24.0 as reverse proxy on CentOS Linux
release 7.9.2009 (Core). I have the below config
file /etc/nginx/conf.d/microservice.conf
I want to capture full request/response body logging in nginx.

# cat /etc/nginx/conf.d/microservice.conf
server {
listen 80;
server_name 192.168.0.129;

location / {
# Capture request headers and body
log_by_lua_block {
ngx.var.request_headers = ngx.req.raw_header()
ngx.var.request_body = ngx.req.get_body_data()
}

# Your regular location configuration here

# Capture response headers and body
body_filter_by_lua_block {
local resp_body = ngx.arg[1]
ngx.ctx.buffered = (ngx.ctx.buffered or "") .. resp_body
if ngx.arg[2] then
ngx.var.resp_body = ngx.ctx.buffered
end
}
}
#nginx -t
*nginx: [emerg] unknown directive "log_by_lua_block" in*
/etc/nginx/conf.d/microservice.conf:8
nginx: configuration file /etc/nginx/nginx.conf test failed

Please guide me. Thanks in advance.

Best Regards,

Kaushal
