Synology DSM, Perl and Mojolicious

Once I remembered Synology DSM in Simultaneously assembling encrypted folders in Synology DSM , I decided to show how using Perl and Mojolicious web framework to make a simple application to fit your needs. I had to write on my knee the utility SynDevInfo , to display the necessary information on the device in the browser, since dear support does not know GNU / Linux, and users cannot log in via ssh.


Under the cat, the structure of the package, the application launch script and the script on Mojolicious :: Lite will be described.

Application launch


Mojolicious supports a bunch of different ways to deploy an application. Using the principle: simple things should be done simply, using the approach described in the Built-in web server . With this method, the script runs in daemon mode and does not require an external web server.


#!/bin/sh export PERL5LIB="${SYNOPKG_PKGDEST}/3rdparty" case $1 in start) /usr/bin/perl ${SYNOPKG_PKGDEST}/SynDevInfo daemon -m production -l http://*:12345 & sleep 5; exit 0 ;; stop) PID=`ps -aef | grep "SynDevInfo" | grep -v grep | awk '{print $2}'` kill -9 $PID exit 0 ;; restart) exit 0 ;; status) exit 0 ;; log) exit 0 ;; esac

In one file and the controller code and html templates. Before starting the I / O processing cycle, the model collects information and serializes it in json. At this point in time, the daemon does not process external requests, so a wait of 5 seconds is written in the startup script. In the helper, this model is deserialized back and displayed in the controller.
