MythWeb - protocol relative URL in the HTML - easier to use SSL with a reverse proxy like nginx

[SaveFerrisVote4Pedro]

A few code changes in MythWeb will change the URLs to protocol relative URLs. This makes it much easier to put MythWeb behind a reverse proxy (like nginx) and add the security of SSL certificates.

In a rendered page of MythWeb, the output includes links written like this

<link rel="stylesheet" type="text/css" href="http://my_myth_tv_server/mythweb/skins/default/style.css">

This breaks behind a nginx reverse proxy (which I use to give myself secure access using SSL), so my MythWeb page looks like this:

They should have the http: removed, so they look like this in the HTML:

<link rel="stylesheet" type="text/css" href="//my_myth_tv_server/mythweb/skins/default/style.css">

That is there should be no http:// in the URL, it should just be //

This would mean that the generated HTML will render correctly regardless of whether the MythWeb is hosted on a http or https webserver.

All that needs to be changed is this line in /usr/share/mythtv/mythweb/includes/defines.php

$root_url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') ? 'https://' : 'http://';

Becomes

$root_url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') ? '//' : '//';

Obviously there's a more elegant way of doing this, but I'm not a php expert. I figured this out with a bit of trial and error.

My version of MythTV

/mythbuntu/33/ubuntu jammy/main amd64 mythweb all 2:33.1+fixes.202401131706.512d723c83~ubuntu22.04.1

It is a simple fix, it won't break MythWeb for anyone, but it will help me not having to go in and edit defines.php everytime MythWeb is updated 😉

MythTV version 34 has a new web app that has all of the function of mythweb at http://backend:6544. You can try that now on the master version of mythbackend and let me know if any change is needed to support the reverse proxy.

Quick reply Peter! Does the v34 look similar to this on v33?

I don't mind this, but I like a direct URL to TV listings etc

Not just staying on http://192.168.1.234:6544/# no matter where you navigate,

MythWeb updates URLs (eg., from https://my_myth_tv_server/mythweb/tv/list and https://my_myth_tv_server/mythweb/tv/recorded) which I prefer

Call me old fashioned! 😎

The V34 app is completely rewritten. In V34 the program guide URL is http://backend:6544/dashboard/program-guide.
