OSM Tile Proxy

Description

OSM Tile Proxy is a proxy/tile cache (written in PHP) for openstreetmap tiles which also can modify the tiles on the fly to create custom colorful maps.

Prerequisites

You will need apache or nginx with PHP support and php-imagick (imagmagick) support.

Installing

• Clone the repository

• copy example/index.php-dist to public/index.php

• make sure your webserver has write permissions on cache/ and log/ directories

• redirect all requests to index.php, e.g. in apache with mod_rewrite

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . /index.php [L]

or for nginx

 location /  {
            include /etc/nginx/fastcgi_params;
            fastcgi_param   SCRIPT_FILENAME  $document_root/index.php;
            fastcgi_pass unix:/var/run/php/php7.3-fpm.sock;
}

your tiles will now be served at

http://<mydomain>/<stylename>/${z}/${x}/${y}.png

CORS Error when hostin tile proxy on subdomain

Hi @NlL5

I use the updated tile proxy on a dedicated sub-domain.
I have set a referrer to limit access to the tile proxy.

currently the code will cause a cors error in this setup because the required header 'Access-Control-Allow-Origin: *' is never set in the code.

I would like to contribute this fix but want to start a discussion before submitting any changes.

My Idea currently is:

default the $referrer to '*'. Use the $referrer to always create the cors header in

osm-tile-proxy/src/TileProxy.php

Line 260 in 0c2e18f

public function handle(): void

Enable the code to use more than one $referrer.

If a referrer other than '*' is set then also limit the CORS header to the given URLs of the $referrer.

What do you think?
