Proxy with processing

[Vladimir K]

It is my problem:

I need functions:

1) change source url (delete exactly params)

2) redirect to other host

3) get request and response for save to logs

my proxy listening  SOURCE_HOST:PORT

I get request like this SOURCE_HOST:PORT/path/path/variable?param_for_delete=345&param_must_be=356453

need redirect to NEW_HOST:PORT/path/path/variable?param_must_be=356453

my solution at this moment:

listen       PORT;

    server_name  name;

    location / {

        access_by_lua_block{

            ngx.req.read_body()

        

            local args = ngx.req.get_uri_args()

          

            args.param_for_delete = nil

            

            ngx.req.set_uri_args(args)

           

        }

            proxy_pass NEW_HOST:PORT;

    }

But I have wrong request NEW_HOST:PORT/path/path/variable?param_for_delete=345&param_must_be=356453

what am I doing wrong?

Look into proxy_redirect in addition to your proxy_pass config.
