root_url not taken into account for template assets and routing using Caddy

[locness3]

I'm trying to set up Shaarli under a subdirectory of my server (without the installation directory being a subdirectory of my server's root content directory).

Previously I used nginx and PHP 7.4, and Shaarli was able to auto-detect that it ran in a subdirectory, and used the proper path for routing and assets, so the site was usable.

Now I'm trying with Caddy and PHP 8.2. Shaarli does not automatically detect the subdirectory so I set general.root_url and general.header_link in Shaarli's config.json.php to the full address of the subdirectory : http://locness.local/grub/ (same results with and without escaping the slashes)

Visiting http://locness.local/grub/ or any URL under that shows a 404 page instead of the correct Shaarli page, probably meaning that the routing ignores the root_url. No CSS nor JS is loaded.

Looking at the page source it turns out those are linked from the webroot :

<link type="text/css" rel="stylesheet" href="/tpl/default/css/shaarli.min.css?v=9f4e2359e31f51e95970e3c8899049eb8f4552822027e20b3429aee78b8b4feb" />

...

<script src="/tpl/default/js/shaarli.min.js?v=9f4e2359e31f51e95970e3c8899049eb8f4552822027e20b3429aee78b8b4feb"></script>

There is only one instance of the root_url being used : the feeds

<link rel="alternate" type="application/atom+xml" href="http://locness.local/grub/feed/atom?" title="ATOM Feed" />
<link rel="alternate" type="application/rss+xml" href="http://locness.local/grub/feed/rss?" title="RSS Feed" />

my Caddyfile

``` http://locness.local { log encode gzip # Set this path to your site's directory. root * /usr/share/caddy # Enable the static file server. file_server handle_path /grub/* { root * /var/www/shaarli_grub php_fastcgi * unix//run/php/php8.2-fpm.sock } } ```

my truncated shaarli config.json.php

``` ```

Let me know if you need any other config.

Hi, could it be a server-side caching problem? Can you delete the contents of tmp/, restart php8.2-fpm, and try again? Does it fix the problem?

I've did it to no avail, I've even rebooted the system a few times but nothing.

Sorry I am not familiar with Caddy, a new section could be added to https://shaarli.readthedocs.io/en/master/Reverse-proxy.html if someone wants to provide a working Caddy configuration.

At first glance I'm not sure handle_path would be the correct directive here, since it strips the prefix. Have you tried with handle or other directives?

Hi @locness3 any news regarding the problem when using Caddy? Were you able to fix it?

I'm having the same issue, but with Docker and Traefik v2. I'm willing to use Shaarli in a subdirectory. Here's the relevant configuration:

config.json.php:

[…]
    "general": {
        "root_url": "https:\/\/subdomain.domain.tld\/liens\/",
        "header_link": "\/liens\/",                       
        "links_per_page": 20,
        "enabled_plugins": [
            "qrcode",
            "default_colors",
            "shaarli2mastodon"
        ],
        "default_note_title": "Note: ",
        "retrieve_description": true,
        "timezone": "Europe\/Paris",
        "title": "Liammoù Ewen",
        "download_max_size": 4194304,
        "download_timeout": 30,
        "enable_async_metadata": true,
        "tags_separator": " "
    },
[…]

docker-compose.yml:

version: '3'

services:
  shaarli:
    image: shaarli/shaarli:v0.13.0
    restart: unless-stopped
    networks:
      - my_network
    volumes:
      - './cache:/var/www/shaarli/cache'
      - './data:/var/www/shaarli/data'
      - './plugins:/var/www/shaarli/plugins'
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.shaarli.rule=Host(`subdomain.domain.tld`) && PathPrefix(`/liens`)"
      - "traefik.http.routers.shaarli.entrypoints=web"
      - "traefik.http.routers.shaarlitls.rule=Host(`subdomain.domain.tld`) && PathPrefix(`/liens`)"
      - "traefik.http.routers.shaarlitls.entrypoints=websecure"
      - "traefik.http.routers.shaarlitls.tls=true"
      - "traefik.http.routers.shaarlitls.tls.certresolver=letsencrypttls"
      - "traefik.http.routers.shaarlitls.tls.domains[0].main=subdomain.domain.tld"
      - "traefik.docker.network=my_network"

networks:
  my_network:
    external: true

As for @locness3, only the feed URLs contain the subdirectory I've set in root_url.

Nevermind, this seems to be a normal behaviour: https://github.com/shaarli/Shaarli/issues/1244#issuecomment-443507059

I customized the Docker image to have a subdirectory. See also https://github.com/shaarli/Shaarli/issues/1778.
