Hi,

is there any to write access log with lua api?

Hello,

Unfortunately access_log and error_log are implemented differently. The exposed ngx.Log API pertains to the error_log which writes immediately. It is not currently possible to write directly to the access log.

You can possibly work around this issue using syslog output, but file output would become a function of your syslog receiver configuration.

If you're looking to write log with Lua, I highly recommend: https://github.com/cloudflare/lua-resty-logger-socket.

1. First initialize a named Unix socket. Here we're using to listen on

sudo -u nobody sh -c 'socat - unix-listen:/tmp/resty.sock,fork

2. With we can establish a connection to the Unix socket for the nginx workers:

http {
    init_by_lua_file conf/init.lua;
}

3. Contents of

logger = require "resty.logger.socket"

if not logger.initted() then
    local ok, err = logger.init {
        path = '/tmp/resty.sock',
    }

    if not ok then
        ngx.log(ngx.ERR, "Failed to initialize the logger: ", err)
    end
end

4. Within you can log messages with:

local message = "Hello from OpenResty"

local bytes, err = logger.log(message)

if err then
    ngx.log(ngx.ERR, "Failed to log message.", err)
    return ngx.exit(ngx.HTTP_SERVICE_UNAVAILABLE)
end

This is interesting, thanks
