Hello,

How to logging requests and responses body using Lua by haproxy?

I have made a configuration for nginx and would like to make a similar configuration for HAProxy. Can someone help me to adapt it?

worker_processes 1;
error_log logs/error.log;

events {
worker_connections 1024;
}
http {
log_format log_req_resp '$remote_addr - $remote_user [$time_local] ’
'"$request" $status $body_bytes_sent ’
‘"$http_referer" “$http_user_agent” “$proxy_add_x_forwarded_for” “$http_x_real_ip” “$http_host” $request_time req_body:"$request_body" resp_body:"$resp_body"’;

server {
    listen 8899;
    proxy_set_header X-Real-IP $http_x_real_ip;
    proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
	proxy_set_header X-Real-Host $http_host;
    access_log logs/access.log log_req_resp;

    lua_need_request_body on;

    set $resp_body "";
    body_filter_by_lua '
        local resp_body = string.sub(ngx.arg[1], 1, 1000)
        ngx.ctx.buffered = (ngx.ctx.buffered or "") .. resp_body
        if ngx.arg[2] then
            ngx.var.resp_body = ngx.ctx.buffered
        end
    ';

    location / {
		proxy_pass	http://172.30.128.11:3000;
    }
}

}
